Replit AI

Replit AI is the agentic layer inside Replit, the browser-based development platform founded in 2016 by Amjad Masad and Haya Odeh. The current flagship, Agent 4, builds full-stack applications from natural language prompts inside a cloud IDE that handles hosting, databases, authentication, and deployment as native features. Replit AI targets a wider audience than traditional coding assistants, covering both professional developers and non-technical builders.

Key Capabilities:

• Agent 4 with parallel multi-task execution across auth, database, backend, and frontend

• Autonomous sessions running up to 200 minutes with Economy, Power, and Turbo effort modes

• Self-testing reflection loop that runs the app in a browser and patches detected issues

• Built-in database, authentication, hosting, and monitoring with zero local setup

• React Native and Expo support for full-stack mobile apps with web-to-mobile conversion

• Design canvas with multi-select, hover state editing, responsive overrides, and variant generation

• 100+ connectors for Stripe, Figma, Notion, Salesforce, BigQuery, Snowflake, and Databricks

• MCP server support for custom tool integration in Agent workflows

• Multiplayer collaborative editing across 50+ programming languages

• Agent-builds-agents capability for automating workflows through Slack, email, and kanban boards

• SOC 2 Type II compliance with SSO, SCIM provisioning, and Bitbucket and GitLab integration
