Replit

Replit is a cloud-based software creation platform that lets anyone build, run, and deploy applications using AI, without installing or configuring any local development environment. Founded in April 2016 by Amjad Masad, his wife Haya Odeh, and his brother Faris Masad, Replit started as a browser-based collaborative coding IDE (originally Repl.it) built to remove the setup friction that kept new programmers from writing their first line of code. The company released its first AI coding agent, Replit Agent, in September 2024, and has since repositioned itself around a broader mission: letting anyone who can use a computer build software by describing what they want.

Replit's current flagship is Agent 4, which writes production-ready code, evolves it based on feedback, and stays out of the builder's way. Agent 4 introduces an Infinite Canvas for visually designing interfaces and applying those designs directly to an app, and Parallel Agents that work on multiple subtasks like authentication, database setup, and design simultaneously while keeping progress visible to the team. A single project can now produce multiple artifacts, including web apps, mobile apps, slides, and videos, sharing a consistent design without switching tools. Every project runs on Replit's built-in full-stack infrastructure, with authentication, database, hosting, and monitoring included by default, plus 100+ integrations connecting to services like OpenAI, Stripe, and Google Workspace.

Replit serves a wide range of builders, from complete non-coders using natural language prompts to professional engineering teams at companies like Zillow, Databricks, Talkdesk, and Gusto, who use Agent 4 for rapid prototyping, internal tools, and production applications. The company reports serving teams from 85% of Fortune 500 companies and raised $400 million at a $9 billion valuation in March 2026, backed by Andreessen Horowitz, Coatue, Georgian, and others. Plans scale from a free Starter tier through Core, Pro, and custom Enterprise offerings with SSO/SAML, single-tenant environments, and VPC peering for security-sensitive organizations.

Replit offers four tiers, with paid plans discounted for annual billing. Starter is free and includes daily free Agent credits, a built-in database, the ability to create slides and videos, and publishing for 1 project (private or password-protected deployments included). Replit Core costs $20/month billed annually and adds $25 of monthly credits, up to 5 collaborators, 2 parallel agents, unlimited workspaces, publishing in any region, and removal of the "Made with Replit" badge. Replit Pro costs $100/month billed monthly or $95/month billed annually, and includes $100 of monthly credits, up to 15 collaborators and 50 viewers, 10 parallel agents, access to the most powerful AI models, and 28-day database rollbacks. Enterprise uses custom pricing and adds custom seat limits, SSO/SAML, advanced privacy controls, design system support, single-tenant environments, static outbound IPs, and VPC peering, available by contacting sales.
