Your Git Branches Are Already A/B Test Variants
If you've ever shipped a landing page from a dist/ folder, you already have the hard parts of an A/B testing platform. You have build artifacts. You have branches. You have a CI pipeline that knows how to push them somewhere. The thing you're missing — the thing Unbounce and Instapage charge $200–$600/month for — is a router that picks one of those builds per visitor and remembers the choice. That's it. That's the whole feature.
This post is about wiring that router in front of your existing build pipeline. Each variant stays a normal git branch with a normal build artifact. BFFless splits traffic across them at the edge and sets a cookie so visitors stay sticky. No SDK, no template lock-in, no per-page pricing.
