Hey r/ProductHunters,

We launched re_gent on PH today.

it’s an open-source tool for people building with AI coding agents.

The problem we kept running into:

AI agents can change a lot of code very quickly, but when something breaks, it’s surprisingly hard to reconstruct what actually happened (especially after /compact).

In Git you can see the final diff, but not:

• which prompt caused a specific change
• what the agent touched along the way
• why it made a certain edit
• what happened before the session was compacted
• how to safely rewind the agent’s work without manually untangling everything

So we built re_gent.

It gives you activity history for AI coding agents, so you can:

• trace what the agent did step by step
• blame a line of code back to the prompt/session that caused it
• rewind agent work across code and conversation
• preserve history across compacted or fragmented sessions

It’s open source, Apache 2.0, and free forever.

We’d love feedback from the Product Hunt community, especially from people already building with Claude Code, Cursor, Codex, or other agentic coding tools.
