ProxAI
Hard budget caps for LLM APIs — one base_url change
ProxAI is a transparent reverse proxy that enforces hard hourly/daily spending caps per LLM API client. Change one base_url — no SDK required. Works with OpenAI, Anthropic, Mistral, Groq, DeepSeek, and 5 more. Over cap → 429 before the upstream is ever called. Worst case is your cap, not your credit card. Self-hostable: single Go binary, ~10 MB Docker image (amd64/arm64), no telemetry. Or use the hosted beta at proxai.eu — free, no credit card. AGPL-3.0. Built end-to-end with Claude Code.
API cost becomes painful surprisingly fast. Curious—what pattern do you see most often when teams realize they actually need ProxAI instead of just monitoring usage manually?
I built ProxAI after reading too many postmortems of agent loops and leaked keys burning API budgets overnight — while provider alerts are monthly and org-wide. It looked like a problem that deserved a hard, technical answer.
Two things I want to be upfront about:
1. I never got burned myself — I built this to prevent it, not recover from it.
2. This project is an experiment: it's built end-to-end with Claude Code, without me writing a single line of code. I specify, review, test and decide; the AI writes. The commit history shows it plainly.
Happy to discuss that workflow as much as the proxy. The self-host path is first-class: docker compose up, multi-arch image on ghcr.io, no telemetry, no account with me.
Happy to answer anything — would especially love feedback from anyone running LLM workloads in prod.

Who hunted ProxAI ?
ProxAI was hunted by Matthieu Chartier. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
