Backport is an open-source API gateway built with FastAPI and Next.js. It adds WAF security, rate limiting, smart caching, and idempotency to any backend — with zero code changes required.
The project started from a simple frustration: adding API gateway features shouldn't mean deploying heavy enterprise solutions like Kong or writing complex middleware. Backport was built to solve this — a lightweight reverse proxy that you can set up in under a minute.
Every request passes through a security pipeline — WAF inspection, rate limiting, cache checks, and idempotency guards — before reaching your origin server. Your backend stays untouched while gaining production-grade protection.
Currently in beta. We're actively building and improving. Check the changelogfor what's new.
