One connection. That is the whole pitch in the image: Claude Code on the left, a single line into OmniRoute in the middle, and 250+ AI providers fanning out on the right. No ten dashboards, no ten API keys to juggle, no coding session dying halfway through a refactor because one provider hit its rate limit.
OmniRoute is a free, open-source (MIT) AI gateway that runs on your own machine. Written in TypeScript on Node.js, it puts hundreds of providers behind one OpenAI-compatible endpoint — http://localhost:20128/v1 — with a web dashboard at http://localhost:20128. Point Claude Code, Codex, Cline, OpenCode, Aider, Copilot, or any OpenAI-compatible client at that address and the tool talks to it as if it were OpenAI. Behind the scenes, OmniRoute picks a provider for each request, and when one fails, runs dry, or goes down, it rolls the request to the next one automatically.
It is not a model. It generates no text itself, and it needs no GPU. It is a router: traffic cop, fallback machine, and cost cutter sitting between your tools and everyone else's models.
What OmniRoute actually is
The key word is local-first. Unlike a hosted gateway, OmniRoute runs as a process on your computer. Your configuration and your provider keys live on your machine, stored with AES-256-GCM encryption, and telemetry is off by default. There is no OmniRoute subscription, no per-token charge from OmniRoute itself, and no account you must create to start. You pay only what your chosen providers charge — and if you only use free tiers, that is zero.
The project moved repositories during 2026 from diegosouzapw/OmniRoute to cheaper-inference/OmniRoute, which is the address to trust now. Its latest release at the time of writing is v3.8.52 (October 19, 2026), and its GitHub star count sits around 82,500 (October 2026). Treat that as momentum, not proof of quality: stars measure excitement, and this is a fast-moving independent project, not a product from Anthropic, OpenAI, Google, or any provider it lists.

The provider count: why you see five different numbers
Do not trust any single provider number for this project, including the one in the image. The image says 250+, and that is a safe headline. But 2026 coverage variously reports 231, 237, 268, 290+, 350+, and 377 providers, with 500+ models, because the catalog grows with nearly every release and different pages count it at different dates. The honest way to say it: 250+ providers (with the project's own counts ranging from roughly 230 to roughly 350+ across 2026 coverage) and 500+ models.
The free-tier side needs the same honesty. Around 90 providers offer some kind of free tier, and 11 were free-forever as of July 2026. The project documents roughly 1.5–1.6 billion free tokens per month across its free-tier pools — but that is the project's aggregate estimate across documented pools, deduplicated so shared quotas are not counted twice, not a promise that you personally can burn through that much. Free tiers are shared, rate-limited capacity with terms that change. Treat the pool as a large buffet, not an infinite one.
How routing works: the 4-tier fallback
OmniRoute's core trick is a four-tier fallback chain. Tier 1 drains your paid subscriptions first — Claude Pro, Codex Plus, GitHub Copilot. Tier 2 uses pay-per-use API keys, the cheap ones. Tier 3 routes to ultra-cheap models. Tier 4 is the free tier pool, which never runs a bill. When a tier hits its quota, returns a 429 rate-limit error, or goes down, quota-aware fallback moves the request to the next tier automatically, backed by circuit breakers, exponential backoff, and per-connection cooldowns.
On top of the tiers sits auto-combo scoring. Instead of sending every request to one fixed model, the auto route scores every available provider across live factors and picks the best per request. Coverage of the scoring write-ups gives the weights: health 25%, quota remaining 20%, cost (cheaper scores higher) 20%, latency 15%, task fit 10%, and stability 10%. Providers that score badly are auto-excluded for a few minutes with progressive backoff, so a sick provider stops getting traffic until it recovers.
The auto family has a variant for each mood. Set your model to auto for the balanced default, which sticks to your last good provider. Auto/coding weights quality first for code generation. Auto/fast chases the lowest latency. Auto/cheap chases the lowest price. Auto/smart is quality-first plus about 10% exploration, deliberately trying other models so it can discover better ones. Auto/offline prefers the most quota and rate-limit headroom. Some setups also expose virtual models like auto/best-free, which resolve per request from whatever free providers you have connected.
| Routing strategy | What it does |
|---|---|
| auto / auto-combo | Scores all providers on live factors and picks the best per request |
| auto/coding | Quality-first weights for code generation |
| auto/fast | Lowest latency first |
| auto/cheap | Cheapest per token first |
| auto/smart | Quality-first plus about 10% exploration of other models |
| auto/offline | Most quota and rate-limit headroom first |
| priority | Fixed order: drain the first provider, then the next |
| round-robin / weighted | Spread requests across providers, evenly or by weight |
| p2c | Power-of-two-choices: sample two providers, use the better one |
| cost-optimized | Route to the lowest-cost eligible provider |
| headroom | Prefer providers with the most remaining quota |
| context-relay | Keeps session continuity when accounts rotate, with a handoff summary |
| fusion | Fans out to multiple models and a judge synthesizes one answer |
| pipeline | Chains steps across providers in sequence |
| quota-share | Deficit round-robin sharing across accounts |
The count of strategies itself moves with releases — 17 in July 2026 coverage, up to 19 or 20 in later versions — so treat "17–20 routing strategies" as the range, and pick from what your installed version actually lists.
Token compression: the honest numbers
OmniRoute runs a stacked compression pipeline before your request leaves the machine. RTK filters and deduplicates tool output — shell results, git diffs, test logs — while Caveman applies rule-based prose shortening. Together the project claims 15–95% token savings. That range is real, but only if you read both ends correctly.
The 95% end belongs to tool-heavy sessions: long git diffs, build logs, and repetitive tool output compress dramatically. Normal prompts typically save 15–30%. And one independent tester measuring their own traffic reported only about 5% from RTK alone — a useful reminder that your mileage depends on what your sessions actually look like. The project says code blocks, file paths, and URLs are preserved byte-perfect through compression, and you can check what really happened per request in the response headers (x-omniroute-decision and x-omniroute-compression), which is the honest way to verify any savings claim on your own traffic.
Performance and the extras
The local hop itself costs milliseconds, but the full request path carries overhead: independent coverage reports roughly 50–150ms extra per request. For a coding agent working through a long task, that is invisible. For rapid-fire interactive chat, you may feel it. Fallback, by contrast, is where the gateway earns its keep — a rate limit or outage on one provider becomes a silent switch instead of a dead session.
Beyond routing, the gateway bundles features that explain why it grew so fast. TLS stealth and header reordering mimic native CLI fingerprints so provider-side checks see ordinary tool traffic. MITM/TPROXY capture catches CLIs that ignore proxy environment variables. Remote mode lets a CLI drive a distant OmniRoute instance (for example on a VPS) with scoped read, write, and admin tokens, while process-spawning routes stay loopback-only. Multi-account pooling spreads load across several accounts on the same provider. A built-in MCP server (87 tools in earlier versions, up to 110 in later ones, over stdio, HTTP, and SSE transports) plus A2A agent-to-agent support (JSON-RPC plus SSE) let an agent drive the gateway itself. Guardrails cover PII, injection, and vision filters.
Security and privacy: what local really means
Local-first is a genuine privacy advantage, but it is easy to overread. What stays on your machine: your configuration, your provider keys (AES-256-GCM encrypted), and your routing decisions, with telemetry off by default. What does not stay on your machine: the requests themselves. Running locally does not mean offline AI — every request still travels to whichever upstream provider the gateway picks, and that provider sees your prompt under its own terms.
So the rule is simple. The gateway removes one middleman (a hosted proxy that would see everything) but it cannot remove the providers. Do not send private, client, or sensitive code through a free tier you have not vetted, and for real work, route sensitive traffic through your own paid key. Also remember the operational side of local-only: you run the updates, you manage OAuth flows, and you are responsible for disk encryption on the machine holding the keys. The gateway gives you control; control comes with chores.
Why developers use it
The benefits stack up in a specific order. First, sessions stop dying: a 429 or an outage becomes a quiet provider switch instead of a lost afternoon. Second, one dashboard replaces a dozen billing pages and key drawers. Third, you can try dozens of models without wiring a new SDK or account for each one — the gateway speaks one API and translates. Fourth, the money story flips: free tiers carry the everyday bulk, and paid frontier models are reserved for the hard 10% of work where quality actually decides the outcome. Fifth, subscriptions stop going to waste: the gateway drains quota you already paid for before it touches anything else.
Three use cases show it best. Refactoring a legacy codebase: long, tool-heavy sessions that used to stall on rate limits now roll across providers while compression trims the tool output. A zero-cost everyday stack: a student or freelancer codes all day on free tiers and only spends on the few calls that truly need a frontier model. Model shopping: a team compares several models on the same task through one endpoint before committing to any provider.
Setup: from zero to Claude Code in minutes
Step 1 — Node.js. OmniRoute needs Node 22.x, 24 LTS (recommended), 25.x, or 26.x, at minimum version 22.22.2. Check yours first, and note that npm 11 and above needs the --allow-scripts flag for the postinstall step:
node -v npm -v
Step 2 — Install and start. One global install, then one command to run it. Guides also recommend setting your own secrets (JWT_SECRET, API_KEY_SECRET, STORAGE_ENCRYPTION_KEY) before the first start rather than accepting defaults:
npm install -g omniroute omniroute
The dashboard opens by itself at http://localhost:20128. If it does not, type that address into your browser. Keep the terminal open — OmniRoute has to keep running while you use it. Docker, a desktop app, Termux on Android, and a PWA install are also available if npm is not your route.
Step 3 — Connect providers. In the dashboard, open Providers and add your first ones. Three options work with no key and no card: Kiro AI (free Claude models), OpenCode Free (several models, no login), and Pollinations (access to GPT, Claude, Gemini, and more). NVIDIA's NIM free tier is another strong early add — coverage notes it imports 51 free models. Start with two or three providers, not the whole catalog, so failures stay easy to diagnose. Then confirm the gateway answers:
curl http://localhost:20128/v1/models -H "Authorization: Bearer YOUR-OMNIROUTE-KEY"
A populated JSON model list means routing works.
Step 4 — Point Claude Code at it. The simplest route is the gateway's own setup command, which writes the config, followed by a launch that injects the endpoint:
omniroute setup-claude omniroute launch --profile auto-coding-free
The manual route is one environment variable: run Claude Code with ANTHROPIC_BASE_URL set to http://localhost:20128, and set the model to auto (or the auto/best-free virtual model, which resolves per request from your connected free providers):
ANTHROPIC_BASE_URL=http://localhost:20128 claude
Other tools follow the same base-URL pattern. Codex takes OPENAI_BASE_URL=http://localhost:20128/v1, and Cline, OpenCode, Continue, and Aider accept the same local endpoint with your OmniRoute key:
OPENAI_BASE_URL=http://localhost:20128/v1 codex
Two honest tool caveats. Not every tool connects the same way. Cursor requires a public URL, not just your laptop, because Cursor's app talks to its own cloud first. Antigravity uses OmniRoute's built-in Google OAuth connector — and note that the built-in Google OAuth credentials only work on localhost, so a remote or VPS deployment needs your own Google Cloud OAuth credentials registered first. Do not expect one identical set of steps for all three tools.
System requirements
Because OmniRoute is a router and not a model, the requirements are refreshingly small. No GPU, no model weights, no cluster. Any modern computer that runs Node.js can run the gateway; the heavy lifting happens on the providers' servers.
| Route | What you need | Notes |
|---|---|---|
| Local gateway (recommended) | Any modern PC, Mac, or Linux machine; Node.js 22.22.2 or newer (24 LTS recommended); a terminal; internet; port 20128 free | No GPU needed at all; storage is a local SQLite database |
| Docker | Docker installed; port 20128 mapped | See the repo for the current image name — it moved with the repo |
| Desktop / mobile | Desktop app, or Termux on Android, or the PWA install | Same gateway, different shell |
| Remote mode | A VPS running OmniRoute, plus scoped tokens for the CLI | Built-in Google OAuth creds work on localhost only — remote setups need your own Google Cloud OAuth credentials |
Pricing: what $0 really means
The gateway costs nothing. The models cost whatever their providers charge. That distinction is the whole pricing story, and it is why the "$0" headline needs one sentence of unpacking: OmniRoute itself is free and MIT-licensed, with no subscription and no per-token charge from the gateway. If you only use free tiers, your total bill is zero. The moment you add paid providers, you pay their rates — the gateway just stops you paying for the wrong tier first.
| Route | Gateway cost | Model cost | Notes |
|---|---|---|---|
| OmniRoute | $0 (MIT) | Only what your chosen providers charge | Free tiers cost nothing but carry their own rate limits and quotas |
| OpenRouter | Hosted service | Prepaid credits at provider list prices | 5.5% platform fee on credit top-ups; free tier is 25+ models, 50 requests per day |
One more pricing honesty note: the roughly 1.5–1.6 billion free tokens per month is the project's aggregate estimate across documented pools, and provider terms change. Check the dashboard's free-tier page before building a workflow that depends on any single pool.
Comparison: OmniRoute vs the other gateways
| Dimension | OmniRoute | OpenRouter | LiteLLM | Portkey | 9Router |
|---|---|---|---|---|---|
| Hosting | Self-hosted, local-first | Hosted cloud | Self-hosted or cloud | Self-hosted or cloud | Self-hosted, local |
| License | MIT | Proprietary service | MIT, with a separately licensed enterprise directory | Open-source core | MIT |
| Providers | 250+ (varies by release) | 500+ models, 80+ providers | 100+ providers | Around 20–30, enterprise-focused | 40+ |
| Free tiers | 90+ providers | 25+ models, 50 requests/day | A handful | None as the pitch | Free tier is the last fallback step |
| Routing | 17–20 strategies, auto-combo scoring | Simple provider routing | Priority and fallback policies | Guardrail-first routing | 3-tier: subscription, then cheap, then free |
| Compression | RTK + Caveman, 15–95% claimed | None built in | None built in | Some built-in reduction | RTK / Headroom / Caveman |
| MCP / A2A | Built in | No | No | No | No |
| Best for | Pure-free starters, feature breadth | Zero-ops simplicity | Python teams, battle-tested self-hosting | Production safety and compliance | People who already pay for a subscription |
OpenRouter wins on zero-ops simplicity: one key, no infrastructure, hosted reliability, and the widest model shelf — but your requests and metadata pass through their servers, and top-ups carry the 5.5% platform fee. LiteLLM is the self-hosted workhorse: simpler than OmniRoute, more battle-tested, Python-native, with spending caps and virtual keys — but no built-in compression pipeline and no built-in MCP server. Portkey is the enterprise choice: guardrails, PII redaction, jailbreak guards, and audit trails, with a much smaller provider list because its pitch is safety, not breadth. 9Router is the closest cousin: a free MIT local router whose three-tier fallback runs subscription first, then cheap, then free — best if you already pay for a subscription and want to drain it before anything else.
The verdict is that there is no universal winner. If your wallet is empty, OmniRoute's free-tier breadth is unmatched. If you want zero maintenance, OpenRouter's hosted service is the honest pick. If you run Python infrastructure and want something proven, LiteLLM is the safe pair of hands. If compliance decides, Portkey. If you already hold a subscription, 9Router's drain-first order fits best. Wallet and hosting preference decide — not a star count.
Who it is for — and who should skip it
OmniRoute is for freelancers and students who want a zero-cost coding stack; for developers tired of rate-limit stalls mid-task; for privacy-minded users who want their keys stored locally rather than in a hosted middleman; and for teams that want to pool quotas across accounts.
Skip it, or pair it with a hosted gateway, if you want zero maintenance, contractual SLAs, or frontier-only quality on every call. If your work is judged on the hardest reasoning and a free model will not cut it, no router fixes that — route the bulk through OmniRoute and keep a frontier model for the few calls that truly need it.
Limitations and fine print
The full catalog means signing up for 15–20 provider accounts if you want all of it; start with two or three. Free-tier terms change, and the free-token totals are estimates, not guarantees. Release velocity is high, which means configuration formats shift — pin your version for anything serious. Documentation is scattered across many pages, so specific answers take digging. Proprietary SDK parameters may need custom mapping rather than working out of the box. Free models do not match frontier quality on hard agent work: combos stretch access, they do not create capability. Local-only by default means you run the updates, the OAuth flows, and the disk encryption. And it remains an independent project — not an official product of Anthropic, OpenAI, Google, or any provider it lists — so there is no vendor support line to call.
Frequently asked questions
Is OmniRoute really free?
The software is free under the MIT license, with no subscription and no per-token charge from the gateway. You pay only what your chosen providers charge. Free tiers cost nothing but carry their own rate limits and quotas, and the roughly 1.5–1.6 billion monthly free-token figure is the project's aggregate estimate, not a personal guarantee.
Does it work with Claude Code?
Yes, and it is the simplest connection. Install OmniRoute, run omniroute setup-claude, then launch with the auto-coding-free profile — or set ANTHROPIC_BASE_URL to http://localhost:20128 manually and use the auto model. Codex, Cline, OpenCode, and Aider follow the same local base-URL pattern.
How many providers does it actually have?
The safe headline is 250+ providers and 500+ models. Coverage across 2026 reports anywhere from about 230 to about 350+ providers depending on the release and the counting date, so check the dashboard's live list for the number that matters to you.
Will it make free models as good as Claude or GPT frontier models?
No. Routing, fallback, and compression stretch access to good models; they do not create frontier capability. Use free tiers for the everyday bulk and keep a paid frontier model for the hard calls where quality decides the outcome.
Is my code private when I use it?
Your keys and configuration stay on your machine, encrypted, with telemetry off by default — but your requests still travel to whichever upstream provider answers them. Do not send sensitive or client code through a free tier you have not vetted, and remember that local does not mean offline.
