Replit is a browser-based, AI-powered platform that lets people turn ideas into working software — websites, mobile apps, dashboards, and internal tools — without needing to set up a local development environment. Founded in 2016 in San Mateo, California by Amjad Masad, Faris Masad, and Haya Odeh, Replit began as a cloud IDE and has since evolved into an 'agentic' app-building platform built around Replit Agent, which plans, writes, tests, and deploys code on a user's behalf.
What it does
At the center of Replit is Agent (currently in its fourth generation), which can run multiple tasks in parallel while keeping progress visible to the user. Agent handles authentication, database setup, and UI design as part of building an app, and Replit describes the workflow as 'vibe coding': the user supplies the idea, taste, and judgment, and Agent turns it into testable software. Beyond the agent, Replit bundles a full application stack — authentication, a built-in PostgreSQL database, hosting, monitoring, and one-click deployment to a live URL — so a project can go from idea to a shareable web address inside the same session. An 'Infinite Canvas' design surface lets teams sketch and apply visual design directly onto an app, and a single project can combine web apps, mobile experiences, landing pages, and short videos with shared design assets. Existing projects can be imported from GitHub, Figma, Vercel, Bolt, Lovable, or a plain ZIP file. Replit also offers more than 100 integrations, including OpenAI, Stripe, and Google Workspace, to connect building blocks into an app quickly.
Pricing
Replit uses a subscription model with monthly usage credits included. The Starter plan is free and includes daily Agent credits, the built-in database, and the ability to publish one project (including password-protected deployments). Replit Core costs $20/month billed annually (or $25/month billed monthly) and adds $25 of monthly credits, access for up to 5 collaborators, 2 concurrent agents, and unlimited workspaces. Replit Pro costs $95/month billed annually (or $100/month billed monthly) and raises the credit allowance to $100/month, collaborator seats to 15, concurrent agents to 10, adds access to more powerful models, 28-day database rollbacks, and premium support. An Enterprise tier with custom pricing adds SSO/SAML, advanced privacy controls, custom seats, and dedicated support.
Who it's for
Replit targets a wide range of builders: non-technical founders and product managers who want to go from idea to a working prototype without writing code, professional developers who want an agent to handle infrastructure busywork, small businesses building internal tools, and teams that need design and engineering to happen in the same collaborative space. Its emphasis on removing manual hosting and credential management, plus instant publishing, positions it closer to a rapid-prototyping and MVP-building tool than a traditional line-by-line coding assistant plugged into an existing IDE, which differentiates it from IDE-embedded copilots like GitHub Copilot or Gemini Code Assist.
