praetr
Praetr is a local-first Windows desktop application that streamlines the workflow from code changes to live deployment. It acts as a safety layer for developers who generate code quickly—whether from AI tools or manual edits—by providing a unified interface to review incoming changes, apply them safely with atomic snapshots, and ship to production with confidence. The tool includes file intake that maps dropped files or ZIPs to the correct project locations, per-file diff review before writing, snapshot-based overwrites, and automatic hot reload in the browser. Praetr also integrates Git: you can commit and push to GitHub from the dashboard, with dirty workspace checks. Deployment is simplified with one-click publishing to Cloudflare Pages, Vercel, or Netlify, complete with post-deploy verification. If something goes wrong, recovery options let you restore files, revert commits, or roll back deployments instantly. Everything runs locally; the API binds to localhost, and secrets are scrubbed from error logs, ensuring your code and keys never leave your machine.
