Replit

Key facts: Replit is a browser-based development platform where you write, run and deploy code without installing anything, and its AI agent can build a working app from a plain-language prompt — then let you edit the result in the same workspace. It supports dozens of languages, real-time collaboration and one-click deployment.

Plans: Replit is free to start with a monthly credit allowance, and paid plans add more agent credits, private projects and higher deployment limits. The free tier is a genuine way to prototype an idea.

Best for: beginners learning to code, hackathon builders and anyone who wants a working prototype fast. Watch out: agent-built apps still need a human to review security, data handling and edge cases before real users touch them.
