Agentic coding is making development and code review more efficient than ever – teams are shipping thousands of PRs in the time it would've taken to manually create a handful. With evals and verification, we're approaching an ideal world where 99% of PRs are written, evaluated, and reviewed entirely by agents.
But that last 1% – the 1% where we still want to personally experience how a new feature looks and feels before signing off on it – is where sidebranch lives. Sidebranch is a browser extension paired with a local sidecar daemon that lets you easily switch between git worktrees while your app is running locally, and compare different branches side by side within a dedicated diff shell. Your working tree, uncommitted changes and all, is never touched.
In-page branch switching Pick any branch from the pill and it builds in an isolated worktree on its own dev server.
🖥️ Side-by-side diffs Both panes live, plus blend and onion diff modes where UI changes are highlighted.
🧘 Framework agnostic Next, Vite, Django, Rails, everything supported as long as it answers HTTP on a port.
📦 Zero dependencies The entire tool is Node builtins, with no external packages or dependencies.

Who hunted sidebranch?
sidebranch was hunted by Cristobal graña. 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.
