Nightshift

It finds what you forgot to look for.

Nightshift is a Go CLI tool that runs AI-powered maintenance tasks on your codebase overnight, using your remaining daily token budget from Claude Code or Codex subscriptions. Wake up to a cleaner codebase without unexpected costs.

Your tokens get reset every week — you might as well use them. Nightshift runs overnight to find dead code, doc drift, test gaps, security issues, and 20+ other things silently accumulating while you ship features.

Like a Roomba for your codebase. Runs overnight, worst case you close the PR.

Key Principles​

  • Everything is a PR — Nightshift never writes directly to your primary branch. Don't like something? Close it. That's the whole rollback plan.
  • Budget-aware — Uses remaining daily allotment, never exceeds your configured max (default 75%).
  • Multi-project — Point it at your repos, it already knows what to look for.
  • Zero config defaults — Works out of the box with sensible defaults. Customize when you need to.
