polyrouter
One endpoint for every model.
polyrouter launched on July 26, 2026.
In plain words
Polyrouter is an open-source, self-hosted LLM gateway that gives developers a single endpoint and API key to route requests across multiple language models. It uses explicit-first routing with automatic fallbacks, enforces hard spending limits, and tracks costs transparently without markup. Users maintain their own API keys and connect directly to providers like OpenAI and Anthropic, giving them full control over their infrastructure and expenses.

Open-source, self-hosted LLM gateway. Point your agents at one URL with one key — explicit-first routing with fallbacks, hard spend limits, and honest, metadata-only cost tracking. Your keys, your box, zero markup.
Open-source, self-hosted LLM gateway. One URL, one key for every model — explicit-first routing, fallbacks, and hard spend limits. Your keys, your box.
Point your agents at one URL with one key. polyrouter routes each request to the right model across your providers — explicit-first, with fallbacks, hard spend limits, and honest cost tracking. Your keys, your box, zero markup. Precedence is dead simple — first match wins. Whatever decides, your budgets and cost recording still apply, and anything that resolves to a tier also gets that tier's ordered fallback chain. All five phases → Filter by how a request was routed, or by fallback and escalation — then open any row: the inspector shows the routing reason verbatim, the workload class the router recorded, tokens, snapshot-priced cost, and latency. Requires Docker with Compose v2. The first…from polyrouter.app

LLM Gateway2025 · llmgateway.io · ▲296I built an OpenAI-compatible LLM gateway that routes requests to OpenAI, Anthropic, Ollama, vLLM, llama-server, SGLang... anything that speaks /v1/chat/completions. Single Go binary, one YAML config file, no infrastructure. It does the things you'd expect from this kind of gateway... semantic routing via a three-layer cascade (keyword heuristics, embedding similarity, LLM classifier) that picks the best model when clients omit the model field, weighted round-robin load balancing across local inference servers with health checks and failover. The part I think is most…
OpenRouter Model FusionApr 2026 · openrouter.ai · ▲144Hey HN, We've been building a multi-model API for LLMs called OpenRouter since we launched the Window AI extension in April this year [0]. The events of the last week make it clear the LLM landscape is unpredictable, so LLM aggregators are picking up interest. Unlike others, we're making a router on top of a public, explorable dataset. We recently built a way to rank and visualize this data, including the token counts we see going to and from different models, both open-sourced (like Llama, Mistral, finetunes, and variants) and closed-sourced (OpenAI, Anthropic). The API supports - 50+…
Any-LLM – Lightweight router to access any LLM Provider2025 · github.com · ▲125We built any-llm because we needed a lightweight router for LLM providers with minimal overhead. Switching between models is just a string change : update "openai/gpt-4" to "anthropic/claude-3" and you're done. It uses official provider SDKs when available, which helps since providers handle their own compatibility updates. No proxy or gateway service needed either, so getting started is pretty straightforward - just pip install and import. Currently supports 20+ providers including OpenAI, Anthropic, Google, Mistral, and AWS Bedrock. Would love to hear what you think!

I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…

OpenSEO▲928Hello! For the last 2 months, I've been building OpenSEO. It's a user friendly UI wrapping the DataForSEO API which has high quality SEO data for keywords, backlinks, AI SEO and competitor research. Instead of paying $100+ per month, you buy DataForSEO credits and pay only for usage. The coolest thing about the project so far has been hearing about what people are building on top of it. People are using coding agents to quickly integrate with Google Search Console, Google Ads and building their own AI SEO and reporting features. Many were already building their own custom solutions around…
