What This Actually Does
You run out of Claude, and then you're stuck
You know the moment. You're deep in a build with Claude Code, it's flowing, and then the usage limit hits. Now you're staring at a wall, waiting hours for your quota to reset, or reaching for your credit card to buy more.
OmniRoute is a free, open-source tool that removes that wall. Instead of Claude Code talking straight to Anthropic, it talks to OmniRoute, running quietly on your own computer. OmniRoute is connected to 290+ AI providers, 90+ of them with free tiers. The moment your Claude usage runs out, it hands the work to a free model and you keep going like nothing happened.
It's over 26,000 stars on GitHub for a reason. This is the setup, in plain English, for someone who has never touched a terminal in their life.
How It Works
One address, four tiers, automatic fallback
Think of OmniRoute as a smart switchboard sitting between Claude Code and every AI model out there. Claude Code sends its request to the switchboard. The switchboard decides who answers.
It works down a ladder of four tiers, in order:
Your Claude subscription. As long as you have usage left, it uses the real Claude, exactly like normal. Nothing changes.
Any API keys you've added. Got a paid key sitting around? It uses that next. Optional, and totally fine to skip.
The cheap models. Low-cost providers that cost pennies, for when you want to stretch further before going fully free.
The free models. 90+ of them. This is your safety net. When everything above is tapped out, it lands here and keeps you coding for $0.
In plain English: OmniRoute always tries your best option first and only drops down when it has to. You never pick a model or babysit a quota. You just keep working, and it keeps finding you a way to answer for free.
The Setup
Three steps, about two minutes
One thing to check first: OmniRoute runs on Node.js (version 22 or 24). If you already use Claude Code, you almost certainly have it. Not sure? Paste node --version into your terminal. If you see a number like v22 or higher, you're set. If not, install it free from nodejs.org first.
Step 1: Install and start OmniRoute. One line. This downloads the tool and starts it running on your computer. Leave this terminal window open, it's your switchboard.
Step 1 — install and launch
npm install -g omniroute && omniroute
Step 2: Grab your key from the dashboard. Once it's running, open http://localhost:20128 in your browser. That's the OmniRoute control panel, living on your own machine. Go to the Endpoints section and copy the access token it gives you. You'll paste it in the next step. That's the only setup the dashboard needs, the free models work out of the box, no accounts to create.
Step 2 — open the dashboard
http://localhost:20128
Step 3: Launch Claude Code through it. Here's the easy part. OmniRoute has a single command that points Claude Code at your switchboard and opens it for you. Run this in a new terminal window and Claude Code starts up already wired for free fallback.
Step 3 — the one command that does it all
omniroute launch
That's it. Claude Code now runs through OmniRoute, and it'll fall back to free models on its own the moment you run out. You don't have to think about it again.
Want to wire it by hand instead? If you'd rather point Claude Code yourself (or you're on a setup where launch isn't handy), it's just two lines. Paste your token from Step 2 where it says your-token-here, run these, then start claude in the same window. One gotcha the docs are firm about: the address has no /v1 on the end. Claude Code adds that itself.
Optional — the manual way (Mac / Linux)
export ANTHROPIC_BASE_URL=http://localhost:20128 export ANTHROPIC_AUTH_TOKEN=your-token-here claude
What You Get
Four things worth knowing about
90+ free models, one endpoint
OmniRoute pools 290+ AI providers into a single address on your own computer. Over 90 of them have free tiers, and 40+ are permanently free. Your Claude Code points at that one address instead of straight at Anthropic, and it can reach every one of those models without you juggling a single API key.
It catches you the moment you run out
This is the part that matters. OmniRoute uses a 4-tier fallback: your Claude subscription first, then any API keys, then the cheap models, then the free ones. The second your Claude usage taps out, it slides down to a free model and you just keep coding. No error, no "come back in 5 hours," no switching tools.
It quietly shrinks your bill too
Built-in compression trims the fat out of what gets sent to the model. The project reports 15% to 95% token savings depending on the request. Fewer tokens per message means your paid usage lasts longer before you ever hit the free tier at all.
It works in the tools you already run
Claude Code is the headline, but the same endpoint feeds Codex, Cursor, Cline, Copilot, OpenCode, and more. Set it up once and every coding tool on your machine gets the same free fallback for free.
The Honest Part
What to know before you dive in
Free models aren't Claude. When you drop to a free tier, you're on a different model, and the quality can be a step down. It's the difference between "keep the momentum going" and "your best possible answer." For serious, important work, stay on your Claude subscription. For grinding through the routine stuff after you've run dry, free fallback is a gift.
Free tiers have their own limits. These are other companies' free plans that OmniRoute pools together. Any single one can hit its own cap or get rate-limited. That's exactly why there are 90+ of them: when one's tapped, it rolls to the next. The pool is the point.
It runs on your computer, not the phone app. This is for coding-style tools like Claude Code, Cursor, and Codex, where the assistant runs commands on your machine. If you're brand new, the desktop Claude Code app is the friendliest place to start.
It's genuinely free and open source. MIT licensed, no account, no paywall, no per-run fee. You install it and it's yours.

Running out of Claude used to mean you were done for the day. Now it just means OmniRoute quietly slides you onto a free model and you keep building. Two minutes, three steps, and you never hit that wall the same way again.
Go set up your safety net.
