Why it holds

A spreadsheet has a race condition.
Yours has bitten you.

Two members open the sheet, both see 14:00 free, both write their name. Somebody drives across town for a laser that is already cutting. That is not a discipline problem — it is what shared documents do.

🔒

One booking wins, always

We fired 7,467 simultaneous booking attempts at one machine and got zero double-bookings — checked against the database, not against our own API's say-so.

🧰

Machines, not people

Built for a resource with a queue: per-machine hours, cooldown between jobs, maintenance windows, and a cap on how far ahead members can book.

🔑

No account to use it

Members book from a link. No seat to buy, no password to reset, no onboarding evening for the whole lab.

Pricing

One price. That is the whole pricing page.

No seats, no per-machine fee, no booking limit, no annual commitment. The number you see is the number you pay.

They also do access control, billing and training records. creneau does not — it does the booking, and it does not charge you per machine for it.

Future-proof

And your members' agents can book it.

Every slot is JSON and every booking is one POST. A member planning a build can have their assistant reserve the laser for Thursday without opening anything — and a taken slot answers 409, so it simply takes the next one.

📊

Slots are data

Hours come back sorted, with bookings, cooldown and maintenance already applied. Nothing to scrape, nothing to click.

🔁

Conflict is a status, not a toast

A red banner stops a human. 409 lets a script branch and carry on. Same board, two audiences.

🚪

Yours to leave

The engine is MIT and self-hostable. If you ever want it on your own box, the door is open and the data is a file.
