MongoDB .local San Francisco · BUILD LAB
ONE PROMPT.
ONE LIVE APP.
One prompt becomes a deployed web app with a MongoDB Atlas database backend and a built-in LLM chosen for the job. You leave with a working production app and a live link.
AVAILABLE INGREDIENTS
Choose the capabilities that make your idea useful.
Use one ingredient or combine a few. Describe the experience you want; the builder selects the specific MongoDB Atlas features and LLM that fit it.
HOW IT WORKS
From idea to a live app.
Describe one useful outcome
Tell us who the app is for and what it should help them do.
Review or submit
Stay for an optional plan review, or let the builder make the product and technical decisions automatically.
We build and verify it
The builder creates the interface, MongoDB Atlas backend, LLM features, tests, and production deployment.
Track it, then open it
After submitting, you get an email with a private tracking link and another when the app is ready. The ready page offers one optional post-build feedback round; your claim code is a backup.
BUILD ASSISTANT
Ask how to turn your idea into an app.
STARTING DATA
15 documents by default. 100 maximum.
15 starter documents
When starter data fits the idea, the builder researches and writes 15 useful documents to MongoDB Atlas by default.
Up to 100 documents
An initial build can contain no more than 100 documents. Apps designed around user-created content may begin empty.
No open-internet search
The live app cannot search the open internet for new data. New documents can come from user input or a user-triggered LLM action.
BUILD + WIN
Participate, play, and compete.
Claw machine token
Use the token you receive after submitting your project to play while your app builds.
Top team + top individual
Projects are ranked on MongoDB and technical ambition, impact and utility, creativity and originality, and the verified implementation.
Three confirmed votes
Each email address gets three votes total. Every vote must be confirmed from the email we send. Voting emails are not used for tracking and are removed from pending votes after confirmation or expiry; only private one-way codes enforce the limit.
