Replit

Replit is a browser-based development platform that lets people build and deploy applications by describing what they want in natural language, alongside traditional code editing for those who prefer to write it directly. Its AI agent, currently called Agent 4, generates code from prompts and can run multiple tasks in parallel while the user watches progress, and a visual "Infinite Canvas" interface lets non-coders assemble web apps, mobile apps, landing pages, and other artifacts without touching code. Every project includes built-in authentication, a database, hosting, and monitoring, so an app can go from idea to a live URL without separate infrastructure setup. Replit supports team collaboration with multiple simultaneous editors and task management, and lists over 100 integrations, including OpenAI, Stripe, and Google Workspace. The platform serves a wide range of users, from hobbyists and non-technical founders prototyping an idea to enterprise teams that need SSO and centralized admin controls. Pricing runs from a free Starter tier with limited daily AI credits up to a $95/month Pro plan and custom Enterprise contracts. Because AI-generated code from natural-language prompts can still produce mistakes, users building anything beyond a simple prototype should expect to review and adjust the generated code themselves.
