Build apps with AI in the 99xDev studio

Why teams choose 99xDev

Full-stack output, built-in data tools, and code you can export when the project outgrows the studio.

Natural language to full stack

The agent scaffolds UI, routes, and data models in one project—iterate in chat until it matches your spec.

Persistence built in

SQLite and migrations ship with every app so you can store users, orders, and content on day one.

See it run instantly

Preview updates as the agent works—share links with stakeholders without deploying staging.

Own your output

Export a standard repo or self-host when compliance or scale requires your infrastructure.

Inside the studio

AI-built app running in preview

From idea to running app

Watch signup flows, dashboards, and CRUD appear in the Preview tab while you refine prompts.

Code editor for AI-built applications

Inspect and extend the code

Open the Code tab anytime—your team can harden, test, and deploy like any React project.

Common questions

Do I need to know how to code?
No for v1—stay in chat and Preview. Technical teammates can jump into the Code tab or export when you need deeper changes.
