Replit
Replit is a browser IDE now running Agent 4, which builds apps, designs, and dashboards from chat. Plans run free to $100/month plus usage credits.
About Replit
Replit is a browser-based coding platform that lets you write, run, and deploy software without installing anything locally, and has expanded into an AI-driven app builder through its Agent product line. You describe what you want in plain language and Agent writes the code, sets up a database, and deploys a live URL inside the same workspace.
What is Replit (2026 update)
Replit combines a full cloud IDE (editor, terminal, package management, hosting) with an AI agent layer that can build complete applications end to end, covering UI, backend logic, database schema, and deployment configuration from a single natural-language prompt. It supports solo developers as well as teams collaborating on the same live project.
What is new in 2026
Replit shipped Agent 4 in 2026, described by the company as a creative partner rather than just a coding assistant. Agent 4 replaced the earlier Design Mode with Design Canvas, an infinite board where you can explore mockups before committing to code, and it dropped the old fork-and-merge collaboration model in favor of teammates working together in one shared project with agent-assisted merging. Agent 4 also runs tasks in parallel, connects directly to outside tools like BigQuery, Linear, Slack, and Notion from chat, and extends beyond web apps into mobile apps, pitch decks, data visualizations, and marketing sites from the same workspace.
Key features
- Full cloud IDE with instant hosting, no local setup required
- Agent 4 builds full-stack apps end to end from natural-language prompts
- Design Canvas for exploring visual mockups before generating code
- Parallel agent tasking so multiple parts of a build (auth, database, frontend) progress at once
- Direct data connections to tools like BigQuery, Linear, Slack, and Notion
- Built-in database, secret management, and one-click public deployment
Pricing in 2026
Replit prices around a free Starter tier plus paid plans that bundle a monthly dollar amount of usable AI credit on top of the subscription fee. Once included credits run out, Agent usage switches to pay-as-you-go billing, so actual monthly cost can run higher than the base subscription price depending on how much you build.
| Plan | Price | What you get |
|---|---|---|
| Starter | Free | Free daily agent usage, 1 published app, one background task at a time, built-in database |
| Core | $20/month ($17/month billed annually) | $20 of monthly AI model credit, Plan mode, unlimited workspaces, badge removal |
| Pro | $100/month ($95/month billed annually) | $100 of monthly AI model credit, 10 parallel agents, up to 15 collaborators, 50 viewer invites, 28-day database rollback, premium support |
| Enterprise | Custom | SSO/SAML, single-tenant environments, static outbound IPs, custom seat limits |
Who should use it
Replit fits solo builders, startups, and non-engineers who want to go from idea to a working, deployed app without managing separate hosting and infrastructure, especially for prototypes, internal tools, and small production apps. It is a weaker fit for large engineering teams with existing complex codebases and strict local development workflows, since heavy Agent usage adds unpredictable pay-as-you-go cost on top of the subscription.
Limitations and alternatives
The main limitation reported by users is cost unpredictability: Agent interactions bill on an effort-based model, so even small requests consume credit, and once your monthly allotment runs out you are charged per use. Unused Core credits also do not roll over between billing cycles, so unused capacity is lost each month. For alternatives, GitHub Copilot Workspace focuses more narrowly on AI-assisted coding inside existing repos, Cursor offers a similar AI-first editor experience with more control over local setup, and Lovable focuses specifically on generating full web apps from a prompt with less emphasis on general-purpose coding. Check the official pricing page for current credit costs before scaling up usage.
Frequently asked questions
What is Replit Agent 4?
Agent 4 is Replit's 2026 AI agent release that builds full applications, designs, and dashboards from natural-language prompts, adds a Design Canvas for mockups before coding, and supports parallel agent tasks and direct connections to tools like BigQuery, Slack, and Notion.
Is Replit free to use?
Yes, the Starter plan is free and includes daily agent usage, one published app, and a built-in database, though paid plans are needed for more agent credit, parallel agents, and higher collaboration limits.
Does Replit charge extra beyond the subscription price?
Yes, once the AI credit included with your plan (for example $20 on Core or $100 on Pro) is used up, further Agent usage switches to pay-as-you-go billing, so your actual monthly cost can exceed the base subscription fee.
How many collaborators can I add on Replit Pro?
The Pro plan, at $100/month, supports up to 15 collaborators plus 50 viewer invites, along with 10 parallel agents and 28-day database rollback.
