Launching today on Product Hunt: GitWhy

Hey everyone 👋 I’m Quan, founder of GitWhy.

GitWhy is the context layer for git. It helps developers save the reasoning behind AI-generated code, link it to commits, and surface it in GitHub PRs for review. It works with Claude Code, Cursor, and other coding agents.

We built GitWhy after running into a simple problem: AI could help write the code, but the reasoning behind it was getting lost. The prompt, trade-offs, and decisions stayed in the chat window, while the team only saw the diff.

Would love your feedback — especially if your team is already using AI heavily in development. How are you making sure the “why” behind code doesn’t get lost? 🎁 For the PH community, we're offering 14 days of Premium free for teams up to 5 seats.
