Parallel by default

Know what every agent is doing—without babysitting terminals.

Open a Workspace when you need it. Keep several Threads moving inside it. The sidebar tells you what is streaming, waiting for approval, or ready for your next prompt.

Reasoning

The retry branch is losing the original payment intent…

Vibe

I found the race: the retry path creates a second intent before the first request resolves. I’m moving intent creation behind the idempotency guard and adding a regression test.

Thin on purpose

Vibe keeps the intelligence.
Mistro gives it a proper room.

No embedded model. No second agent loop. Vibe Mistro speaks the Agent Client Protocol, supervises the process, and turns its live work into a desktop interface.

Your call, at the right moment

Stay in the loop without living in the loop.

Permission requests arrive inside the Thread that caused them. Approve one action, reject it, or choose a different approval posture for the work ahead.

  • 02Accept edits while guarding commands
  • 03Give trusted Threads more autonomy

Everything beside the conversation

The side work stays beside the work.

Inspect files, review a diff, stage a change, or open a real shell without losing the Thread that explains why you are doing it.
