> AI-powered full-stack web app builder that turns plain-language descriptions into real React + Express + SQLite projects with built-in database, storage, and hosting.

99xDev is a web-based AI app builder made by the team at 99x that converts plain-language prompts into deployable full-stack web applications. It targets solo makers, founders, and agencies who want real, exportable code without local setup. The platform is actively live and featured on Product Hunt.

## What It Is

99xDev is an AI-powered vibe-coding platform that generates React + Express + SQLite full-stack codebases from natural-language descriptions. Unlike tools that produce static prototypes, it produces a runnable project with a real backend, database migrations, and file storage — all managed inside a browser-based studio. Users can iterate with the AI agent through multi-turn chat, preview the running app live, and export the full codebase as a ZIP at any time.

## How the Workflow Works

The platform follows a four-step flow described on the homepage:

- **Describe**: Write what you want in plain words (or paste a screenshot/image).
- **AI builds**: The agent writes code, runs migrations, wires up storage, and autofixes issues with live streaming progress in chat.
- **Use the studio**: Manage the database, files, and logs without leaving the workspace.
- **Ship**: Publish to a custom domain or download the full repo to self-host anywhere.

No local environment setup is required at any stage.

## Studio Architecture

The built-in studio has four main tabs:
- **Preview** — live running app view with a shareable preview link.
- **Code** — full project file tree and editor showing the generated React + Express codebase.
- **Database** — table browser and read-only SQL console backed by SQLite with migrations.
- **Prompts** — a library of 18+ integration recipes (auth, Stripe, OpenAI, email, and more) that send a pre-written prompt to the agent in one click.

Per-project object storage for uploads, images, and files is also built in, so no external bucket or database service needs to be provisioned.

## Target Audience and Use Cases

The homepage lists specific use-case landing pages for internal tools, dashboards, MVPs, founders, and agencies. The AI agent supports multi-turn building with clarifying questions and autofix, making it suited for non-engineers who want a working app as well as developers who want to skip boilerplate. Workspaces support team invites with owner, admin, and member roles.

## No Lock-In Export Model

A key differentiator the site emphasizes is code ownership: users can download a standard React + Express + SQLite repository at any time and run it on a laptop, VPS, or cloud provider. Custom domain support lets users point their own hostname at a published app with DNS verification handled by the platform.
