Prototypes, built by a crew that never sleeps.
Hand Protocrew a brief tonight. A crew of AI agents plans it, builds it, tests it in a real browser and hands you a working prototype with a preview link and the code by morning.
Under the hood
Real code.
Real tests.
This is what the crew actually writes: TypeScript on its own branch, then the full test suite, lint and build. Only green work goes to review, and only reviewed work reaches main.
Brief in.
Prototype out.

Art direction
Concept, moodboard, type and motion are set before a line of code.
one signature moment per page
Build
Builders claim tasks from the board, each on its own branch, tests first.

Review
Reviewers test in a real browser at three widths and send weak work back.

Checkpoint. You.
At every phase the crew stops and waits for your yes, your comments or a new direction.

Preview link, code you own, a final report and a time-lapse of the build.

Meet the crew
Five specialists.
Zero stand-ups.
Clara
ArchitectTurns your brief into a plan the crew can build without stepping on each other.
- Superpower
- Cuts work so five agents never touch the same file.
- Habit
- Keeps a register, so nothing gets built twice.
Jonas
Builder · interfaceOwns everything you see: design system, pages, motion.
- Superpower
- Typography, layout and animation that feel finished.
- Habit
- Takes interface work only, nothing else.
Mia
Builder · backendAPIs, data, accounts and sandboxes behind every screen.
- Superpower
- Fixes what review finds, fast.
- Record
- Closed a data leak eleven minutes after it was found.
Paul
ReviewerRuns the full test suite on every single change.
- Superpower
- Nothing reaches the main branch without him.
- Habit
- Says no politely, and says why.
Lena
ReviewerTests like a hostile user in a real browser, at three screen widths.
- Superpower
- Finds what nobody asked her to look for.
- Record
- Spotted a security hole on her own initiative.
Proof, not promises
It built its own platform. Yours is next.
Overnight
From a brief in the evening to a clickable prototype with a preview link in the morning.
Self-built
The platform you see here was planned, built and tested by the crew itself.
Gated
Nothing reaches the main branch without a reviewer and a fully green test suite.
Any AI
Works with the AI subscriptions you already pay for, and switches when one runs low.
Any machine · any AI
Your server. Your subscriptions.
Protocrew measures the hardware it lands on and sizes the crew to fit. It pools the AI accounts you already pay for and moves work to whichever has quota left, so one limit never stops the shift.

When one subscription runs low, the crew moves its work to another one. Automatically, mid-shift.

When to use something else.
Lovable · Bolt · v0
A page in ten minutes
- One agent, their cloud, their stack
- Great for a quick mock-up
- No crew, no review, no checkpoints
Devin · Factory · Agent HQ
An agent in your repo
- Built for enterprise codebases
- One task at a time, or agents side by side
- Their infrastructure, their pricing
Protocrew
A crew that ships a prototype
- Architect, builders and reviewers on one board
- Your hardware, your AI subscriptions
- Live view, preview links, checkpoints for clients
- Real code with tests a team can take over
Who it is for
Studios first. Investors welcome.
Studios and agencies
- Show a working prototype at the second meeting
- Clients watch the build and comment on the preview
- Every comment becomes a task on the board
- Final report and code archive for the handover
Investors
- Problem: prototypes take weeks; coding agents speed up people, not delivery.
- Product: a managed AI crew with process, on any hardware, with any provider.
- Traction: two products shipped, one of them its own platform; studio pilots next.
- Model: per project for studios first, self-service later.
- Team: DESATIV Studio, Munich, since 2013.
