How it works

From spreadsheet to internal app in four steps.

No platform team required.

  1. 1

    Connect your data

    Use built-in SQLite or connect Postgres or MySQL from the Database tab—build on data you already have.

  2. 2

    Describe the workflow

    Tell us the approvals, CRUD screens, roles, or dashboards you need. The AI agent scaffolds routes, UI, and schema.

  3. 3

    AI builds for you

    Watch it write code, run migrations, wire integrations, and fix issues—with live progress in chat.

  4. 4

    Ship your way

    When you are ready to go live on your terms, see how to ship.

See the studio

Preview, code, database connections, and integrations

in one workspace.

Live preview

Open your internal tool in the Preview tab as the AI builds.

Share a preview link with teammates—or publish when you are ready.

Real full-stack code

Browse and edit your project in the Code tab.

The same React + Express app you can export—no proprietary runtime.

Connect any database

Built-in SQLite for greenfield tools—or connect Postgres and MySQL to your existing data.

Browse tables and run read-only SQL without leaving the studio.

Integration prompts

18+ drop-in recipes—auth, Stripe, OpenAI, email, and more.

Search the library and send a prompt to the agent in one click.

When you are ready

Ship your way

You own what you build.

Publish on your hostname or take the full stack anywhere—no Retool-style lock-in.

Download the code

Export a standard React + Express repo anytime. Run it on your laptop, VPC, or cloud—the same project you edited in the studio.

Connect a custom domain

Point your own hostname at a published app. Verify DNS, set a primary domain, and we route traffic for you while you keep building.

Three ways to ship

Same platform — pick how much help you want.

From DIY trials to a senior developer on your workspace.

Starter

$20/mo

You describe the internal tool, AI builds it. Great for ops teams and first admin panels.

Start free trial

Pro

$100/mo

More projects and messages when you ship multiple internal apps or iterate fast.

Start Pro trial

Expert

$500/mo

A dedicated senior developer builds your internal tools on your workspace. You own the code.

Request Expert build

Data without the enterprise tax

SQLite included free. Postgres and MySQL connectors built in.

No separate database project to provision for v1.

Connect your database
Embedded SQLite for new tools—or connect Postgres and MySQL to build admin panels and dashboards on existing data.
Built-in storage
Per-project object storage for uploads, images, and files. Upload, browse, and serve assets from the same workspace as your app.

And there is more

Keep iterating with the agent and bring teammates into the same workspace.

AI agent in the loop
Multi-turn builder with streaming updates, clarifying questions, and autofix when something breaks.
Workspaces and invites
Share a workspace with teammates. Invite by email with owner, admin, or member roles.

Frequently asked questions

01What internal tools can I build?

Admin panels, approval queues, inventory trackers, support dashboards, customer 360 views, and any CRUD workflow with roles and a database.

02How is this different from Retool?

Retool is drag-and-drop on a proprietary runtime. 99xDev builds real React + Express code you can audit, export, and self-host—at SMB-friendly pricing.

03Can I connect my existing database?

Yes. Connect Postgres or MySQL from the Database tab in your project. New tools can also start on built-in SQLite.

04What do paid plans include?

More projects and monthly messages, custom domains on Starter and Pro, and priority support. See pricing for details.

05How do I sign up?

Use Google sign-in or email with a one-time verification code. A card is required to start your 7-day trial — you are not charged until the trial ends.
