A gateway is a single endpoint in front of many model providers. It adds routing, fallbacks, cost tracking and access control.\n\n## Most widely used\n\n- **LiteLLM** is the open-source, self-hosted default. One source lists it as having the widest adoption, with 53.8K GitHub stars, 100+ providers, and a Python-first design. It's best when you want control and are willing to run it yourself. The same source advises you to pin and verify releases.\n- **OpenRouter** is a managed service with nothing to run. It's recommended for a large model catalog behind a single OpenAI-compatible endpoint. It also suits smaller teams, since it offers breadth and unified billing.\n- **Portkey** is aimed at governance and guardrails. It has an MIT license, 1,600+ models, and is now backed by Palo Alto Networks.\n- **Cloudflare AI Gateway** is managed and runs at the edge. It fits if you already front everything with Cloudflare and want basic caching. Its core features are free.\n- **Vercel AI Gateway** is a managed gateway for teams building with Vercel, Next.js or the AI SDK. It advertises zero markup on tokens.\n- **Kong AI Gateway** suits teams that already run Kong. It's best for enterprises already running a Kong API mesh.\n- **AWS Bedrock** and **Azure** make sense if you're already in those clouds. One comparison says these options make sense only when a gateway needs to sit inside infrastructure you already run.\n\n## Newer or more specialized\n\n- **Bifrost** (by Maxim AI) is an open-source Go gateway that claims about 11 µs of overhead at 5,000 RPS.\n- **TrueFoundry** is a Kubernetes-native AI gateway with governance, RBAC, and budgets.\n- **Helicone** puts logging and analytics first, gateway second.\n\n## Quick picks\n\n| Need | Pick |\n|---|---|\n| Self-hosted and open source | LiteLLM |\n| Zero ops, many models | OpenRouter |\n| Enterprise guardrails | Portkey |\n| Already on Cloudflare, Vercel or Kong | That vendor's gateway |\n| Very high throughput | Bifrost, or LiteLLM alternatives |\n\nSeveral of these \"top 5\" lists were published by gateway vendors.

Why people use it: It is widely considered the fastest way to stand up a local or self-hosted proxy with budget tracking, virtual keys for different teams, and load balancing out of the box. Check out the details on Vercel's Open Source AI Gateways Comparison. Bifrost (Best for High-Performance Enterprise & Platform Teams) What it is: An open-source, highly performant gateway engineered for minimal latency overhead (roughly 1 1 𝜇 𝑠 at 5,000 requests per second). Why people use it: It can be deployed fully air-gapped, on-premises, or inside a private VPC under an Apache 2.0 license, making it a top pick for security-heavy enterprise environments. Cloudflare AI Gateway (Best for Teams Already on Cloudflare) What it is: A managed cloud service that sits on Cloudflare’s edge network. Why people use it: If your infrastructure already touches Cloudflare, it offers dead-simple setup, built-in caching (to instantly save money on repeated prompts), rate limiting, and real-time analytics without managing dedicated proxy servers. OpenRouter (Best for Model Exploration & Prototyping) What it is: A hosted model marketplace and unified API router. Why people use it: It gives you a single API key to access hundreds of different open-source and proprietary models. While less suited for locked-down enterprise data governance, it is unmatched for trying out different LLMs on the fly. Kong AI Gateway (Best for Enterprise API Management) What it is: The AI extension of the ubiquitous Kong API Gateway ecosystem. Why people use it: Large enterprises that already use Kong for traditional microservices can leverage its native AI Proxy plugins to route, secure, and monitor LLM traffic alongside normal backend traffic—including zero-code tracing integration with observability tools like Langfuse.

Adoption shows in GitHub stars (e.g., LiteLLM’s high count), forum discussions, and repeated mentions in comparisons. There is no single “best”—it depends on self-hosting needs, performance, governance, or existing stack (e.g., Cloudflare or Kong).[[3]](https://blog.redlinesoft.net/posts/best-ai-proxy-gateway-2026/)[[4]](https://www.citehawk.com/leaderboards/ai-gateways)\n\nHere are the **top brands/products people actually use**, drawn from 2026 comparisons, adoption signals, and real-world feedback:\n\n- **LiteLLM** — Most widely adopted open-source/self-hosted option (MIT license core; ~53.8K GitHub stars reported). Supports 100+ providers, virtual keys, per-team budgets, fallbacks, caching, and Prometheus metrics. Python-first proxy (self-hosted via Docker/Helm or hosted/enterprise tiers). Best for teams wanting full control and zero markup on their own keys. Trade-offs: Ops overhead at scale (multiple services like Postgres/Redis); some note latency or config sprawl in production. Frequently the default self-hosted pick.[[1]](https://www.marktechpost.com/2026/10/14/best-ai-gateways-2026/)[[5]](https://www.edgewisely.com/7-best-ai-gateways-in-2026-kong-litellm-truefoundry-portkey-cloudflare-helicone-and-openrouter-compared/)\n\n- **Portkey** (now integrated into Prisma AIRS / Palo Alto Networks) — Strong for enterprise governance, guardrails, routing/fallbacks, semantic caching, observability, and compliance (SSO, RBAC, audits). Self-hosted core (MIT/Apache) + managed/private cloud options; supports 1,600+ models. Good for production safety and prompt management. Trade-offs: Hosted tiers meter logs; enterprise features may require paid plans. Popular for teams prioritizing controls over pure self-hosting.[[1]](https://www.marktechpost.com/2026/10/14/best-ai-gateways-2026/)[[2]](https://www.requesty.ai/blog/best-ai-gateways-2026)\n\n- **OpenRouter** — Leading managed aggregator/marketplace for broad, low-friction access (400–500+ models from 60+ providers). One API key, automatic fallbacks/routing (by price/latency/etc.), OpenAI-compatible. No self-hosting needed. Popular for quick prototyping or unified billing. Trade-offs: ~5.5% fee on credit purchases (pass-through inference pricing otherwise); hosted only (data transits their service). Strong for developers wanting zero ops.[[6]](https://llmscape.com/gateways/)[[7]](https://aitoolsbakery.com/blog/best-ai-llm-gateways/)\n\n- **Bifrost** (Maxim AI) — High-performance self-hosted Go binary (Apache 2.0). Ultra-low overhead (~11 µs at 5K RPS), strong for high-throughput workloads. Supports multiple providers, load balancing, fallbacks, semantic caching, and MCP/tool traffic. Best for performance-sensitive or high-RPS self-hosted setups. Trade-offs: Fewer providers than LiteLLM in some reports; newer ecosystem. Often praised in benchmarks vs. LiteLLM.[[1]](https://www.marktechpost.com/2026/10/14/best-ai-gateways-2026/)[[8]](https://www.lyzr.ai/blog/best-ai-agent-gateways-compared/)\n\n- **Kong AI Gateway** — Best if you already run Kong for API management. Extends to LLM/MCP/A2A traffic with plugins/policies for routing, limits, caching, and guardrails. Open core + commercial options. Trade-offs: Steeper learning curve if not already in the Kong ecosystem; AI features can feel retrofitted. Solid for platform/API teams.[[1]](https://www.marktechpost.com/2026/10/14/best-ai-gateways-2026/)[[9]](https://www.requesty.ai/blog/ai-gateway-vs-api-gateway)\n\n**Other notable mentions** (widely discussed for specific use cases):\n- **Cloudflare AI Gateway**: Managed edge proxy with free core features (caching, logging, rate limits). Ideal if already on Cloudflare.[[2]](https://www.requesty.ai/blog/best-ai-gateways-2026)\n- **Vercel AI Gateway**: Managed, zero token markup, tight integration with Vercel AI SDK. Good for Vercel/Next.js users.[[2]](https://www.requesty.ai/blog/best-ai-gateways-2026)\n- **Helicone**: Observability- and logging-first (cost tracking, traces); self-host or managed. Complements routing gateways.[[2]](https://www.requesty.ai/blog/best-ai-gateways-2026)\n\n**Quick decision guide** (common recommendations):\n- Self-hosted control/no markup → LiteLLM or Bifrost.\n- Broad models, zero infra → OpenRouter.\n- Governance/guardrails/enterprise → Portkey/Prisma AIRS.\n- Existing stack (Cloudflare/Kong/Vercel) → Use the native one.\n- Observability focus → Helicone (or pair with others).\n\nMany teams start with OpenRouter or LiteLLM for speed, then layer governance or switch for scale/performance. Evaluate based on your volume, compliance needs, data residency, and whether you want to self-host. Check current docs/pricing for the latest (features and acquisitions evolve quickly). Reddit threads and benchmarks often highlight real ops trade-offs like latency or setup effort.","extractedBrands":[{"name":"LiteLLM","domain":null,"position":1},{"name":"Portkey","domain":null,"position":2},{"name":"OpenRouter","domain":null,"position":3},{"name":"Bifrost","domain":"maximai.com","position":4},{"name":"Kong AI Gateway","domain":"konghq.com","position":5},{"name":"Cloudflare AI Gateway","domain":"cloudflare.com","position":6},{"name":"Vercel AI Gateway","domain":"vercel.com","position":7},{"name":"Helicone","domain":"helicone.ai","position":8}]},{"provider":"openai","run":1,"model":"gpt-6-sol","capturedAt":"2026-11-01T05:14:26.145Z","text":"Assuming you mean **gateways for LLM APIs**—one endpoint for accessing models, routing requests, and controlling usage—these are the established products I’d shortlist.
