Summary

Handler is a Mac app built by solo developer Vignesh that lets developers review AI-generated code in smaller, reviewable edits (similar to stacked PRs) while the AI agent is still generating. Each edit includes an explanation of what changed, why, and what it affects. Users can open side chats on specific edits to ask follow-up questions or request changes without disrupting the main agent run. The app works with Codex and OpenCode.

While the agent is generating code, Handler breaks the work into smaller reviewable edits.

Each edit comes with a short explanation: what changed, why it changed, and what it touches.

If something feels unclear, you can open a side chat on that specific edit and ask follow-ups... without derailing the main agent run.

The idea is similar to why stacked PRs are easier to review than one giant diff.

Snippet from the RSS feed

Every edit the agent proposes arrives with a built-in explanation and its own chat. Ask why, what it touches, or tell it to redo it. None of it derails the main agent.
