Limit Extender
Limit Extender stretches your coding subscriptions with input and output token reduction and smart model routing. Combine two $20 pro plans — Claude and Codex — and get more than one $100 Max plan, for less than half the price.
With Limit Extender Pro you run Claude and Codex pro plans combined. Token reduction and model routing make those limits last dramatically longer — so you get Max-plan capacity without the Max-plan price.
UsageX reduces input and output token use while preserving the result, so your existing limits last longer.
Requests are routed to the model that fits the job, saving your heavy-model quota for the work that actually needs it.
Token optimization is designed to preserve the requested result. Fewer tokens, identical quality.
Extend your Codex plan with token reduction and model routing. $7.99/month excl. VAT.
See pricing →Run both pro plans as one extended pool — never hit your limits again. $16.99/month excl. VAT.
See pricing →Three steps, then you stop thinking about limits.
Link your Codex plan (Starter) or your Claude and Codex pro plans together (Pro). Limit Extender treats them as one extended pool.
Nothing changes in your workflow. UsageX reduces token use and routes each request to the right model automatically.
Fewer tokens per task and smarter model use mean the same subscriptions stretch dramatically further. Never hit your limits again.
Starter works with your Codex plan. Pro combines your Claude and Codex pro plans into one extended pool.
Two $20 pro plans plus Pro ($16.99 excl. VAT) is about $57/month with more combined capacity than one $100 Max plan — and you keep both ecosystems.
No. Easy tasks genuinely don't need heavy models, and the hardest work still goes to Opus Planner. Routing and token optimization are designed to preserve the result — 0% quality loss.
