Google Firestore

Here’s the practical shortlist I’d recommend in 2026, focusing on products people actually use—not obscure “cool” databases.

Quick picks

My ranked recommendations

1. Amazon DynamoDB — best battle-tested serverless database overall

Use it when you’re on AWS and need huge scale, low latency, and minimal ops. DynamoDB is fully managed/serverless, requires no server provisioning or patching, supports on-demand pay-as-you-go pricing, and can scale down to zero throughput when idle. (aws.amazon.com)

Best for: high-scale APIs, serverless backends, event-driven apps, carts, sessions, user metadata, IoT, gaming.
Avoid if: you need rich ad hoc SQL queries, joins, or flexible relational modeling.

---

2. Neon — best serverless Postgres

If you want “normal Postgres” but with serverless behavior, Neon is the standout. It supports autoscaling, scale-to-zero/autosuspend, and database branching, which makes it popular for modern web apps, Vercel/Next.js apps, AI tools, and dev/test environments. (neon.com)

Best for: SaaS apps, AI apps with pgvector, modern web apps, dev/staging branches, teams that want Postgres compatibility.
Avoid if: you need the absolute most mature enterprise Postgres platform with traditional dedicated instances.

---

3. Firebase / Google Cloud Firestore — best for mobile/web realtime apps

Firestore is a serverless NoSQL document database for storing, syncing, and querying app data at global scale, with strong integration into Firebase and Google Cloud. (firebase.google.com)

Best for: mobile apps, realtime collaboration, offline sync, Firebase-native apps, frontend-heavy teams.
Avoid if: your data is highly relational or you need complex SQL analytics.

---

4. Amazon Aurora Serverless v2 — best serverless relational DB on AWS

Aurora Serverless v2 is a good pick if you want MySQL/Postgres compatibility with AWS-native autoscaling. It now supports scaling to 0 ACUs with automatic pause/resume in supported configurations, which makes it more “serverless” than older Aurora Serverless v2 setups. (docs.aws.amazon.com)

Best for: AWS teams that need relational SQL, migrations from MySQL/Postgres, production apps with variable load.
Avoid if: you need ultra-simple pricing or low-cost hobby projects; Aurora can get expensive and has more AWS/RDS complexity.

---

5. Supabase — best “app backend with Postgres”

Supabase is not “pure serverless Postgres” in the same way Neon is: Supabase projects run on dedicated Postgres compute, and compute size changes are not automatic zero-downtime autoscaling. But it is widely used because it bundles Postgres, Auth, Storage, Realtime, Edge Functions, REST/GraphQL APIs, and now branching workflows. (supabase.com)

Best for: indie SaaS, internal tools, Firebase alternative, apps that need auth + database + storage quickly.
Avoid if: your main requirement is true scale-to-zero database compute.

---

6. PlanetScale — best serverless-ish MySQL/Vitess workflow

PlanetScale is a strong choice if you want MySQL compatibility, Vitess-based scaling, safe schema changes, and database branching/deploy-request workflows. Its big differentiator is developer workflow around schema changes and scaling MySQL-style workloads. (planetscale.com)

Best for: MySQL teams, SaaS apps, schema-heavy production workflows, apps that may need horizontal scaling.
Avoid if: you specifically want Postgres features, extensions, or the PostgreSQL ecosystem.

---

7. Cloudflare D1 — best SQL database for Cloudflare Workers

D1 is Cloudflare’s managed serverless SQL database based on SQLite semantics, built directly into the Workers platform. It’s especially attractive if your app already runs on Cloudflare Workers and you want a simple relational database close to that ecosystem. (cloudflare.com)

Best for: Cloudflare Workers apps, edge APIs, small-to-medium relational workloads, low-cost serverless projects.
Avoid if: you need mature Postgres/MySQL features, high write throughput, or broad database tooling.

---

8. Turso — best SQLite-style edge / microdatabase option

Turso is a SQLite-compatible database platform focused on many small databases, edge workloads, and agentic/AI use cases. It’s compelling when you like SQLite’s simplicity but need a managed cloud story and lots of lightweight isolated databases. (turso.tech)

Best for: edge apps, per-tenant databases, AI agents, local-first-ish architectures, lightweight SQL.
Avoid if: you need traditional Postgres/MySQL semantics or heavy concurrent write workloads.

---

9. Upstash Redis — best serverless cache / queue / rate-limit DB

Upstash is the go-to serverless Redis-style service. It offers pay-per-request pricing, scales to zero when idle, and works well from serverless and edge functions via HTTP without connection-pool headaches. (upstash.com)

Best for: caching, rate limits, queues, sessions, ephemeral state, AI agent memory.
Avoid if: you need it as your primary relational/document database.

---

10. Azure Cosmos DB serverless / Azure SQL Database serverless — best if you’re Azure-native

Cosmos DB serverless charges for consumed request units and storage without capacity planning, while Azure SQL Database serverless automatically scales compute, can auto-pause during inactivity, and bills compute per second. (learn.microsoft.com)

Best for: Azure shops, enterprise apps, Microsoft stack, global NoSQL workloads, SQL Server-compatible workloads.
Avoid if: you’re not already on Azure; the mental model and pricing can be less appealing than simpler alternatives.

---

Honorable mention: MongoDB Atlas — use Atlas, but not “Atlas Serverless”

MongoDB itself is widely used, but MongoDB Atlas Serverless instances are no longer the thing to choose: MongoDB says Atlas stopped supporting M2/M5 clusters and Serverless instances as of January 22, 2026, with migrations to Free, Flex, or Dedicated clusters. If you want MongoDB, look at Atlas Flex or dedicated Atlas clusters instead. (mongodb.com)

Avoid: Fauna for new projects

Fauna was once a notable serverless database, but Fauna announced in March 2025 that it would sunset the Fauna service and stop accepting new customers. Don’t start new production work on it. (fauna.evanweaver.com)

My opinionated recommendation

For most new projects:

1. Use Neon if you want SQL/Postgres and modern serverless behavior.
2. Use DynamoDB if you’re AWS-native and can model your access patterns upfront.
3. Use Supabase if you want a full backend platform, not just a database.
4. Use Firestore if you’re building mobile/realtime apps.
5. Use Upstash Redis alongside any of the above for cache, queues, sessions, and rate limiting.
6. Use Cloudflare D1 or Turso when your app is edge-first or SQLite-shaped.

If you’re unsure, pick Postgres—usually Neon for serverless Postgres or Supabase if you also want auth/storage/realtime. PostgreSQL remains one of the most widely used and admired databases among developers, and Stack Overflow’s 2025 survey highlighted PostgreSQL as the top database developers wanted to use or keep using. (stackoverflow.co)

Best Serverless Databases (2026)

Serverless databases have become the default choice for modern app development because they eliminate server management, scale automatically, and often let you pay only for what you use. Here's a breakdown of the top products people actually use, organized by category.

🐘 Serverless SQL / Postgres & MySQL

Neon – The leader for serverless Postgres. It separates storage and compute, allowing your database to scale to zero when idle. It offers PostgreSQL with full compatibility, scale-to-zero pricing, database branching (like git for your schema), instant database cloning for testing, and autoscaling based on load. It's a favorite for startups and Vercel/Next.js deployments. Neon dropped prices 15-25% after the Databricks acquisition — its Launch plan starts at $19/month with 300 compute hours and 10GB storage.

Supabase – Supabase is the go-to when you want more than just a database. It's the full-stack choice when you want auth, storage, real-time, and Postgres in one platform.

PlanetScale – Originally known for MySQL/Vitess, it now also offers Postgres. PlanetScale now serves two distinct needs: low-cost managed Postgres and MySQL-compatible Vitess for horizontal scale, branching, and online schema changes. It has no free plan, but single-node Postgres starts at $5/month; production-grade and Vitess configurations cost more.

TiDB Cloud – A strong pick if you expect unpredictable traffic spikes. TiDB is a distributed MySQL database whose "Starter" plan is fully serverless and handles "spiky" traffic better than most — if a marketing campaign suddenly sends 10,000 users to your site, TiDB's architecture is designed to spread that load across nodes automatically.

Prisma Postgres – Positioned as the DX optimizer for developers who want tight tooling integration.

⚡ Edge/SQLite-Based

Turso – The top choice for latency-sensitive, globally distributed apps. Turso is built on libSQL (an open-source fork of SQLite) and is the one to pick if you care about latency above all else. Its free tier includes 5GB storage, 100 databases, and 500M row reads/month — the most generous free tier in the market. It also has a unique feature: embedded replicas let you run a Turso database inside your application process with automatic sync to the remote database.

📦 NoSQL / Document & Key-Value

Amazon DynamoDB – The classic enterprise-grade choice. It's AWS's fully managed, serverless NoSQL database built for ultra-low latency, massive scale, and seamless performance. It auto-scales to handle traffic spikes, offers predictable single-digit millisecond response times, and integrates tightly with the wider AWS ecosystem — designed for high-performance workloads like gaming, IoT, and real-time personalization.

Google Cloud Firestore – The best fit for mobile/real-time apps tied to the Firebase ecosystem. It's Google's scalable, serverless NoSQL database designed for real-time applications across web, mobile, and IoT, offering strong synchronization, offline support, and automatic multi-region replication, so developers can focus on building features without managing infrastructure.

IBM Cloudant – A lesser-known but capable option. It's one of the few NoSQL databases that scales elastically as a pure serverless offering — for teams running distributed apps that need global throughput and managed replication, its auto-sharding and always-on availability just work.

The landscape of serverless databases has expanded significantly, driven by the decoupling of compute and storage. In a serverless database model, the database automatically scales up during traffic spikes, scales down (often to zero) when idle, and bills you strictly for the storage and compute queries you actually use.

The following are the top serverless databases that developers and enterprises actually use, categorized by their data models and primary use cases.

---

1. Relational (SQL) Serverless Databases

For modern web apps, SaaS platforms, and standard relational workloads, these are the market leaders.

Neon (Serverless Postgres)

Neon has quickly become the developer favorite for serverless PostgreSQL. It separates compute from storage, allowing databases to scale down to zero when they aren’t being used, saving massive amounts of money on inactive preview environments or dev databases.

• Best For: Modern web applications, Next.js/Vercel projects (Neon actually powers Vercel Postgres), and rapid prototyping.
• Why people love it: Database Branching. You can instantly branch your database (schema and data) just like a Git branch to test migrations or new features safely.
• The Catch: If a database scales to zero, there is a minor "cold start" latency (usually 1–2 seconds) when the database wakes up for the first query.

Supabase (Postgres Backend-as-a-Service)

While Supabase is technically an entire open-source backend suite, its core is serverless-friendly PostgreSQL. It handles the database, authentication, file storage, real-time sync, and edge functions in one unified platform.

• Best For: Full-stack apps, MVPs, and projects where you want a "Firebase-like" developer experience but want to stay on Postgres.
• Why people love it: Real-time listeners, a beautiful UI, built-in vector search (via pgvector), and rapid setup.
• The Catch: While it has generous free and usage-based tiers, the underlying database compute is conventionally provisioned behind the scenes, meaning it doesn't "scale to zero" in the same way Neon does unless configured specifically.

Turso (SQLite at the Edge)

Turso is built on libSQL (an open-source fork of SQLite) and is designed to run close to your users on edge networks. It allows you to run hundreds of thousands of isolated database instances globally.

• Best For: Low-latency edge applications, multi-tenant SaaS (where every tenant gets their own micro-database), and mobile-backend synchronization.
• Why people love it: Virtually zero cold starts, sub-millisecond query latency when run from edge functions, and an extremely generous free tier (which includes up to 9GB of storage across multiple databases).
• The Catch: SQLite has limited support for highly complex concurrent write operations compared to Postgres or MySQL.

Amazon Aurora Serverless v2

If you are already embedded in the AWS ecosystem and need enterprise-grade scaling, Aurora Serverless is the gold standard. It scales database capacity (ACUs) up and down instantly in response to application demand.

• Best For: High-traffic, highly variable enterprise workloads, and legacy SQL migrations to AWS.
• Why people love it: Seamless multi-region replication, extreme reliability, and compatibility with standard Postgres and MySQL.
• The Catch: It does not scale to zero. Even when your database is completely idle, you must pay for a minimum allocation (usually 0.5 ACUs), making it expensive for small side projects or hobbyists.

---

2. Document & NoSQL Serverless Databases

For unstructured data, high write throughput, and massive scale.

Amazon DynamoDB

DynamoDB is the "OG" serverless database. It is a fully managed, multi-region NoSQL database that offers single-digit millisecond latency at virtually any scale.

• Best For: High-volume APIs, microservices, and massive gaming or e-commerce backends.
• Why people love it: Its "On-Demand" mode is truly serverless; you only pay for the exact read and write request units (RRUs/WRUs) your application uses. It handles massive throughput spikes without breaking a sweat.
• The Catch: Highly restrictive query pattern requirements. If you need to perform complex ad-hoc queries, joins, or aggregations, DynamoDB’s key-value design makes it incredibly frustrating to use compared to SQL.

MongoDB Atlas Serverless

This is the official serverless deployment option for MongoDB. It offers the flexible JSON-like document model that developers love, but with automated scale-to-zero compute provisioning.

• Best For: Applications built on the MERN/MEAN stack that experience highly unpredictable or bursty traffic.
• Why people love it: You get the full power of MongoDB's expressive query API without having to provision or pay for idle cluster instances.
• The Catch: If your database has consistent, steady-state traffic, the serverless tier can end up being significantly more expensive than MongoDB’s standard provisioned tiers.

---

3. Specialized & Reactive Serverless Databases

These databases are built for specific, modern application architectures like AI/Vector Search and real-time collaborative state management.

Convex (Reactive Document Backend)

Convex is a rising star in the serverless space. It is a reactive database where the frontend is directly synchronized with the database. Instead of writing SQL or setting up WebSockets, you write TypeScript functions that run directly inside the database platform.

• Best For: Real-time collaborative apps (like Figma or Notion clones), live chat, and AI-agent workflow orchestrations.
• Why people love it: If any data changes, the UI updates automatically across all active users in real-time. It completely eliminates the complexity of WebSockets, state sync, and caching layers.
• The Catch: It uses its own custom query engine rather than standard SQL, locking you into the Convex ecosystem.

Pinecone (Serverless Vector Database)

Pinecone is the dominant serverless vector database used to store high-dimensional machine learning embeddings, which are necessary for Retrieval-Augmented Generation (RAG) and LLM memory.

• Best For: Generative AI applications, semantic search, and AI agent memory.
• Why people love it: Unlike older vector database architectures that required expensive, dedicated compute pods running 24/7, Pinecone Serverless separates compute from storage, allowing you to store massive vector indexes in cheap object storage and only pay for active searches.
• The Catch: Highly specialized. It is strictly a vector database; you cannot use it as your main application relational database.

Upstash (Serverless Redis / Kafka)

Traditional Redis is memory-bound and requires an active, expensive server. Upstash solved this by creating a Serverless Redis (as well as serverless Kafka and QStash queues) billed entirely on per-request usage.

• Best For: Caching, rate-limiting, session management, and job queues in serverless architectures (like Next.js on Vercel or AWS Lambda).
• Why people love it: Extremely fast (sub-millisecond), scales to zero, and integrates perfectly with edge runtimes where traditional TCP connection pooling is difficult.
• The Catch: Because of its on-demand HTTP API translation layer, it can have slightly higher latency than a traditional, self-hosted Redis cluster deployed on the same virtual network.

---

Important caveats

“Serverless” is often used loosely. Check whether the product actually scales to zero, has cold starts, connection limits, and predictable pricing at scale. Some popular options — like Supabase, Aurora Serverless v2, and PlanetScale — are managed/auto-scaling rather than always pure scale-to-zero. MongoDB Atlas is hugely popular, but its Serverless tier has been deprecated/steered toward Flex/dedicated clusters, so verify current status before choosing it.

For most startups and indie projects today, the common real-world picks are Supabase or Neon, plus Upstash, and Pinecone/pgvector for AI search. For enterprise AWS/GCP/Azure shops, DynamoDB/Firestore/Cosmos DB and their managed relational/analytics companions are the safest bets.

Neon, Supabase, Turso (libSQL/SQLite), PlanetScale (MySQL/Vitess), Cloudflare D1, and established options like AWS DynamoDB and Aurora Serverless v2 stand out as the most-used serverless databases in 2026.

These are highlighted across developer comparisons, benchmarks, adoption signals (e.g., GitHub activity and production mentions), and real-world recommendations for variable/bursty workloads, edge apps, and serverless/edge architectures. Popularity favors Postgres-based solutions for general web/SaaS use, with strong NoSQL and edge alternatives.

Top Recommendations (Relational/SQL Focus)

These dominate recent discussions for new projects and production use:

• Neon (Serverless PostgreSQL): Frequently cited as the default or top pick for most developers in 2026. It separates compute from storage for true scale-to-zero (pay nothing when idle), instant database branching (git-like clones for previews/CI/CD), and strong Vercel/Next.js integration. Cold starts are typically ~300–500 ms (or faster with minimum compute). Generous free tier (e.g., 512 MB storage with auto-suspend). Excellent DX with broad ORM support (Prisma, Drizzle, etc.). Best for: General web apps, bursty traffic, dev/staging environments, Postgres users.

• Supabase (PostgreSQL + Backend Platform): Extremely popular all-in-one open-source platform (managed Postgres + auth, storage, realtime, edge functions, vectors). Not always "pure" serverless (paid plans often keep compute always-on; free projects may pause after inactivity). Strong for rapid full-stack development. Best for: MVPs, apps needing built-in backend services beyond just the DB. Many teams start here for speed.

• Turso (libSQL/SQLite fork): Optimized for edge and low-latency reads via distributed replicas and embedded-replica patterns (reads can be local/microseconds). Excellent cold starts and multi-tenant support (easy per-tenant DBs). Generous free tier. Best for: Edge-first apps, global read-heavy workloads, multi-tenant SaaS, or SQLite-compatible stacks. Often praised for performance in specific architectures.

• PlanetScale (MySQL-compatible via Vitess, with Postgres options emerging): Excels at safe, zero-downtime schema changes via branching/deploy requests and horizontal scaling/sharding. Strong for high write throughput. Free tier was removed (more production-oriented). Best for: Existing MySQL teams, complex migrations, or large-scale relational workloads.

• Cloudflare D1 (SQLite): Tight integration with Cloudflare Workers for cheap, serverless SQLite at the edge. Good free tier and low latency. Best for: Cloudflare ecosystem users or simple edge apps.

Strong NoSQL/Key-Value and Cloud-Native Options

These see heavy real-world production use, especially at scale:

• AWS DynamoDB: The classic, battle-tested serverless NoSQL (key-value/document) with instant scaling, global tables, and millisecond latency. Widely adopted in AWS ecosystems for high-traffic, real-time, or simple access-pattern apps (e.g., IoT, gaming, mobile backends). True pay-per-use with no cold starts.

• AWS Aurora Serverless v2 (MySQL or PostgreSQL compatible): Auto-scaling relational option deeply integrated with AWS. Scales in seconds but has a minimum compute floor (not true scale-to-zero). Best for: AWS-native apps with variable but not fully idle workloads.

• Others worth noting: MongoDB Atlas Serverless (flexible document model), CockroachDB Serverless (distributed Postgres-compatible for global consistency), and Upstash (serverless Redis for caching/sessions).

Quick Decision Guide

• New web/SaaS app or Postgres preference — Start with Neon (or Supabase for full backend features).
• Edge/low-latency or multi-tenant — Turso or D1.
• MySQL stack or heavy schema changes — PlanetScale.
• High-scale NoSQL or AWS-heavy — DynamoDB or Aurora Serverless.
• All-in-one backend fast — Supabase.

Key considerations: True scale-to-zero saves costs on idle workloads but introduces cold starts (trade-offs vary by product). Pricing is usage-based (compute hours, storage, reads/writes) with varying free tiers—check current details as they evolve. Most support standard drivers/ORMs, though serverless/HTTP modes help with connection limits in functions.

These recommendations reflect consensus from 2025–2026 comparisons and developer feedback. Evaluate based on your stack (SQL flavor, cloud provider, latency needs), traffic patterns, and team expertise—many allow easy migration later. Test free tiers for your workload.

The top serverless databases widely used today include Neon, Supabase, Turso, PlanetScale, Fauna, MongoDB Atlas, and Amazon Aurora Serverless, each excelling in specific workloads from MVPs and web apps to global high-traffic platforms.
