DEVELOPER PREVIEW
Your next agent should know what changed.
Register free, and it will. The Developer Preview is for developers who code with an AI agent every day. It takes a minute.
Vybright will reach back through your code’s history as far as you want. For the Developer Preview we’ve reined that reach in to a rolling history of your last 5 changes, for testing.
The Developer Preview is for a selected group of developers who run AI coding agents every day. You get the AI Code Ledger on your own repositories, a direct line to the people who built it, and a say in what ships next.
What you get to do in the Developer Preview
Whole undo
Undo an entire agent change. Everything goes back. Your other work stays.
One-change undo
Remove the bad part of a change and keep the good work.
Chained undo
Take back a change and the later changes built on it, in one move.
A clear no
Where a change cannot be taken back cleanly, nothing goes back and you get a clear reason.
A record you can check
Every change and every undo, from the first snapshot forward, checkable by you.
Why join now
The Developer Preview is small on purpose. Every developer in it talks to the Vybright team directly, and what you report shapes the beta. If you have ever watched an agent rewrite a paragraph when you asked for a word, you already know what we are fixing.
It runs beside the tools you already use. Cursor, Claude Code, Copilot and Codex write to one record and read the same record back. Nothing about your editor or your workflow changes.
- Free for you
- No credit card
- No new editor
What we ask
Run it on real work. If something breaks, the tool gives you a link to tell us. If your token bill changes, tell us there too.
Smarter context. Better AI code.
When agents write most of the code, somebody has to keep the receipts. That is Vybright.
