Describe your idea and Replit builds a working app in minutes
Describe the product you want and the agent plans, codes, tests and iterates on a working full-stack application.
Authentication, databases, hosting and monitoring work out of the box, so apps scale without separate DevOps work.
A no-cost mode lets you brainstorm and build without spending tokens before upgrading to stronger models.
Connect services such as OpenAI, Stripe and Google Workspace in minutes rather than writing glue code.
An open-source toolkit for adding AI agents to your React app
Register your existing React components once and the agent renders them with the correct props, inheriting your styling, design system and business logic instead of inventing new markup.
Streaming, message threads, cancellation, error states, conversation storage and component state are handled for you, so AI features do not require rebuilding core app infrastructure.
The agent inherits the signed-in user's permissions and session, keeping AI features inside your existing security and authorisation boundaries.
Model Context Protocol integration on both sides connects the agent to external tools and data sources, with MCP OAuth support for authenticated servers.
