Build Fullstack Web Apps using AI
99xDev is an AI internal tool builder that enables teams to create full-stack web applications by connecting their database and describing workflows in plain English. It positions itself as a Retool alternative for small and medium-sized businesses and operations teams who need custom internal tools without extensive development resources. The core value proposition is generating real, production-ready React and Express code that users fully own and can export anytime. By leveraging AI to handle the scaffolding, routing, schema, and integration wiring, 99xDev dramatically reduces the time from idea to shipping an internal application.
Traditional internal tool development often requires dedicated developer time, leading to either long delays or reliance on spreadsheets and manual processes. Proprietary low-code platforms like Retool can be expensive and lock users into their runtime, making customization and self-hosting difficult. 99xDev directly addresses these pain points by generating standard, auditable code that can be run anywhere. Teams no longer need to wait for engineering cycles or sacrifice code transparency. The AI agent handles the heavy lifting of writing routes, UI components, and database migrations, allowing non-technical staff to build and iterate on internal tools independently while maintaining full code ownership.
Database connectivity is a foundational feature. 99xDev provides built-in SQLite for greenfield projects and supports connecting existing Postgres or MySQL databases. Users access the Database tab within the studio to browse tables, run read-only SQL queries, and understand their schema before the AI builds the application. This direct connection means the generated internal tool works with live production data from the start, without import or export steps. The agent can interpret the database structure to create appropriate CRUD screens, approval workflows, and dashboards that reflect actual business data, making the tool immediately useful.
The AI workflow builder is the core of the platform. Users type a description of the internal tool they need—for example, an approval queue for purchase requests with role-based views or an inventory admin with low-stock alerts. The AI agent then scaffolds the entire application: routes, UI components, database schema, and integrations. It operates as a multi-turn conversational builder, providing streaming updates, asking clarifying questions, and automatically fixing issues when errors occur. The chat interface shows live progress as code is written, migrations are run, and dependencies are installed, giving users transparency and control over the build process.
