Replit
AI app-building platform where autonomous coding agents build, test, and deploy full-stack web and mobile apps from a prompt.
What it does
Replit is a cloud-based AI development platform where an autonomous coding agent (currently Agent 4) writes, tests, and deploys apps from natural-language prompts. It includes a built-in database, a visual design canvas, publishing/hosting, and support for running multiple agent tasks in parallel across a shared project.
How to use: Sign in at replit.com and describe the app you want; Agent builds it — writing the code, wiring the database, and iterating with you. Use the design canvas to change the look visually while the agent keeps building other parts in parallel: multi-select, hover and active state editing, responsive overrides, and 'Generate variants' to explore options in context. When it is ready, publish from the same project. The Starter plan gives free daily Agent credits; Core and Pro include monthly credit allowances.

FAQ
Do I need to know how to code?
No. Replit's Agent builds apps, sites and decks from a description, and the design canvas lets you adjust the result visually rather than in code.
What is Agent 4?
The current generation of Replit's app-building agent, which can work on parts of your app in parallel while you design other parts.
Can I design without leaving the app?
Yes — the design canvas edits designs visually and applies them directly to the app, including responsive overrides and interaction states.
Is there a free plan?
Yes. Starter is $0/month and includes free daily Agent credits.
What do the paid plans cost?
Core is $20/month billed annually or $25/month billed monthly; Pro is $95/month billed annually or $100/month billed monthly. Both include a monthly credit allowance.
