Replit

Short verdict: Replit is a cloud development platform whose Agent 4 plans, builds, tests and hosts apps from a prompt. It runs up to 10 background tasks in parallel on Pro, keeps checkpoints you can roll back, optionally including the database, and publishes to its own usage-billed hosting with managed Postgres. The main catch is cost: Agent work, hosting and databases draw from one credit balance under effort-based pricing, and on Starter and Core there is no documented way to keep your content out of Replit's model training. Free Mode, added in August 2026, softens the bill with no-credit work in 5-hour windows. It suits founders and small teams who want one place to build and run apps; developers who live in a local editor, or who need a fixed monthly cost, should look elsewhere.

How we reviewed it: We did not sign up for Replit or run Agent. On 21 October 2026 we read the pricing page in monthly and yearly billing, Replit's docs on plans, Agent modes, models, billing, publishing, checkpoints, background tasks and model improvement, the changelog, the Pro Agreement, the privacy policy and the Free Mode announcement. Plans and limits change often; check the pricing page before you pay.

What Replit costs and includes

What Replit adds to prompt-to-app building

A cloud workspace that is not limited to JavaScript

Each project runs in a cloud workspace with unlimited development time on paid plans, and Replit can stream native desktop apps written in Python, Java or C++ to the browser over VNC. It imports from GitHub, Bitbucket, Vercel, Figma, ZIP files and Bolt, Lovable or Base44 exports, and Agent can open a pull request on GitHub.

Parallel tasks on a board

Agent splits work into tasks on a board and runs them in the background in isolated copies of your project: 1 at a time on Core, up to 10 on Pro and 64 on Enterprise. You review each task's log, tests and preview before applying it, and Agent resolves conflicts between tasks with AI.

Checkpoints that can include the database

Every completed request creates a checkpoint of your files, Agent context, settings and database, and one click rolls them back (the database only if you select it). Pro keeps 28 days of point-in-time database recovery instead of the standard 7.

Hosting priced by use

Published apps run on Autoscale ($0.60 per million compute units and $0.40 per million requests, plus a base fee), Reserved VMs from $15 a month, scheduled jobs, or free static hosting with $0.05 per GB of transfer, per Replit. Production Postgres costs $0.16 per compute hour and $0.35 per GiB a month after price cuts on 1 August 2026. Agent can also build native iOS apps and upload them to App Store Connect for TestFlight.

Credits, effort pricing and other catches

• Effort-based pricing. "The Agent will spend more credits as it works longer," per Replit's pricing FAQ, so a complex build costs more than a bug fix, and on the paid path even Plan Mode reasoning can be billed. Higher Effort settings add up to about 2x on hard tasks.

• One balance for building and running. A budget is a hard cap: when you reach it, Replit suspends all usage-based services until the next cycle or a higher limit.

• Expiry. Core credits do not roll over, Pro credits last 2 months, and credit packs expire after 6 months.

• A thin free plan. Starter's single published app goes down after 30 days, and it has no Plan Mode, connectors or background tasks.

• Training controls only on Pro. Replit uses "your prompts, instructions, context, and responses generated for you" to improve its models. Pro users can opt out and Enterprise content is excluded; the docs describe no opt-out for Starter or Core.

• Unpublished Free Mode limits. Free Mode, added on 18 August 2026, has 5-hour and weekly limits that Replit does not give as numbers.

Pros and cons

Pros

• A full cloud workspace that is not tied to JavaScript.

• Up to 10 parallel background tasks on Pro, each reviewed before it merges.

• Checkpoint rollback covers files, Agent context and, if you choose, the database.

• Free Mode covers everyday Agent work without credits on Core and Pro.

• Hosting, Postgres, domains and native iOS submission in one account.

Cons

• Effort-based charges make a month's bill hard to predict, and hosting draws on the same credits.

• Reaching a budget suspends usage-based services.

• Only Pro and Enterprise keep content out of model training.

• Starter's only published app expires after 30 days.

• Free Mode limits are not published as numbers.

How Replit compares

• Bolt.new runs a Node.js environment in the browser and bills tokens rather than effort: Free includes 1M tokens a month and Pro costs $25 a month for 10M. Its backends must be JavaScript. Choose it for JavaScript web apps or Expo mobile apps if you would rather budget in tokens.

• Lovable costs $25 a month for 100 credits on Pro and lets every Free and Pro user opt out of model training, which Replit allows only on Pro at $100 a month or more. Choose it for web apps when you want that opt-out without Replit Pro's price.

• Claude Code is Anthropic's agent for your own terminal and editor (macOS, Linux, Windows, VS Code and JetBrains), from Claude Pro at $20 a month, or $17 billed yearly; it has no free tier and no hosting. Choose it if you are a developer who wants an agent working on your local codebase.

Who should use Replit

Use Replit if you want one cloud account to build, test, host and keep iterating on apps with an agent, especially if you need more than JavaScript, parallel tasks for a small team or a native iOS app. Look elsewhere if you need a fixed monthly cost, prefer your own editor and hosting, or need your code kept out of model training without paying for Pro.

FAQ

Is Replit free?

Yes. As of 21 October 2026 the Starter plan costs $0 and includes daily Agent credits up to a monthly cap, a capped Free Mode and 1 published app that goes down after 30 days. Core costs $20 a month, or $18 a month billed yearly, and includes $20 of monthly credits for Agent, hosting and databases.

How does Replit charge for Agent?

By effort. Each request you send in Build mode ends in one checkpoint, priced by how much work Agent did and the mode and model you chose, so a complex feature costs more than a bug fix. Free Mode work costs no credits within an allowance that resets every 5 hours, with weekly limits, on Core and Pro; Power and Max modes draw on your monthly credits and then pay-as-you-go.

Does Replit use my code to train its models?

Yes, unless you are on Pro or Enterprise. Replit's docs say it uses your prompts, instructions, context and the responses generated for you to improve its models; Pro users can opt out under Settings, Personalization, Enterprise content is not used, and the docs describe no opt-out for Starter or Core.

Can Replit build mobile apps?

Yes. Agent builds iOS and Android apps that you preview on your phone with Expo Go, and Replit's Launch feature builds, signs and uploads iOS apps to App Store Connect for TestFlight and App Store review. You need your own Apple Developer Program membership.
