Description

Fillo is a developer tool that lets AI coding agents build forms directly into applications, handling form generation as a discrete, well-defined capability an agent can call rather than having the agent hand-write form markup and validation logic from scratch each time. It is aimed at developers using AI coding agents who want reliable, consistent form-building instead of agent-generated form code that varies in quality each time.

Supadev is a web app that generates six types of AI-optimized project documentation -- covering requirements, tech stack, frontend and backend architecture, security guidelines, and an implementation plan -- which you paste into any AI coding assistant so it produces accurate, context-aware code. It's aimed at individual developers, indie builders, and small teams who want to ship features faster with fewer AI-generated bugs. Its differentiator is that it focuses on the upstream documentation layer rather than being another code generator, working alongside tools like Claude, Cursor, Copilot, and Replit.
