Replit – Build Apps with AI Agent 4 | No Coding
Build production-ready web, mobile, and design apps in minutes with Replit's Agent 4. AI handles code, design, and deployment. Free tier available.
Replit is a browser-based IDE powered by Agent 4, an AI system that builds full-stack applications from natural language prompts. It enables teams to design visually on an infinite canvas, execute parallel tasks simultaneously, and deploy to production instantly—all without manual infrastructure setup. Built-in authentication, PostgreSQL database, hosting, and monitoring eliminate configuration overhead. Available globally with US and India data center options. Pricing starts free (limited) and scales to enterprise custom pricing.
Pricing
Starter (free) with limited Agent access. Core at $20/month (annual) with $25 monthly credits. Pro starts at $100/month with tiered credits up to $4,000/month. Enterprise custom pricing. Effort-based billing applies to Agent usage beyond included credits—simple tasks cost $0.06+, complex tasks $1-5+.
Frequently Asked Questions
What is Agent 4 and how does it differ from previous Replit agents?
Agent 4 is Replit's most capable AI agent, featuring parallel task execution where multiple agents work simultaneously on different parts of your app (auth, database, frontend, design) while maintaining a shared understanding of the project. Previous agents worked sequentially. Agent 4 also introduces an infinite design canvas and task-based workflows with Kanban boards for team collaboration.
Can I use Replit for HIPAA-compliant healthcare applications?
No. Replit explicitly does not offer HIPAA-compliant hosting and does not provide Business Associate Agreements (BAAs). While it has SOC 2 Type 2 compliance, this does not meet HIPAA requirements. You must use a platform with a signed BAA for any application handling Protected Health Information (PHI).
How does Replit's effort-based pricing work?
You pay per task ('checkpoint') based on the computing resources and time the Agent uses. Simple tasks cost $0.06-$0.25; complex builds cost $1-5+. All plans include monthly credits ($25 for Core, tiered for Pro), and unused credits roll over one month. Once credits deplete, you're charged pay-as-you-go. The 'effort' is based on CPU/RAM consumed, making costs unpredictable.
Does Replit support mobile app development?
Yes. With Agent 4, you can build native iOS and Android apps directly in Replit. You can convert existing web apps to mobile apps seamlessly or build mobile-native projects from scratch. Mobile apps share the same backend and design system as your web app in a single unified project.
What integrations does Replit offer?
Replit offers 100+ integrations including: OpenAI, Anthropic, Google Gemini, Stripe, Notion, Linear, Slack, Databricks, BigQuery, Google Workspace, and native Replit Auth. You can also use bring-your-own-API-key options for additional providers via OpenRouter.
Is Replit free? What's the best tier for me?
Starter is free but limited (1 vCPU, public projects only, limited AI access). Core ($20/mo annual) is best for solo developers. Pro ($100/mo) suits small teams with Turbo mode (2.5x faster builds) and tiered credits. Enterprise (custom) is for orgs with SSO/SAML, VPC peering, and compliance needs.
How is Replit different from Cursor or GitHub Copilot?
Replit is a full-stack platform: IDE + AI agent + design canvas + built-in infrastructure (auth, database, hosting, deployment). Cursor and GitHub Copilot are primarily code assistants for existing IDEs. Replit targets non-technical users and teams seeking end-to-end app building; Cursor targets professional developers wanting IDE-integrated coding help.
