Replit

Replit is a browser-based coding platform that includes Replit Agent, an AI that builds working apps from a plain-language description. You can write code, run it, store data and publish the result without installing anything, which makes it popular with beginners, founders and anyone prototyping quickly. Its billing is credit-based, with the Agent’s work charged by effort.

Quick facts

• Made by: Replit, a company founded in 2016 and based in San Francisco
• Free plan: Yes. Starter includes daily Agent credits up to a monthly cap and one published app.
• Paid plans: Core and Pro, plus a custom Enterprise plan
• Works on: Web, iOS and Android
• Pricing last checked: October 2026, using several recent published sources. Replit changed its plans in February 2026, so older pages show different prices. Confirm on Replit’s official pricing page.

What Replit is best at

• Building apps from a description: ask the Agent for an app and iterate by chat.
• Everything in one place: editor, running environment, database and hosting in the browser.
• Quick publishing: deploy a working app with a few clicks.
• Learning and prototyping: a low-friction way to try an idea or learn to code.
• Small team building: collaborators can work in the same project, with pooled credits on Pro.

Plans and pricing

Credits pay for Agent work, deployments, compute and storage. The Agent is billed by effort, so a bigger request costs more, and once credits run out usage is billed on a pay-as-you-go basis. That means the subscription fee is predictable but your total bill is not. Confirm all figures on Replit’s official page.

Best for

• Beginners and non-developers who want to turn an idea into a working app.
• Founders prototyping a product quickly.
• Small teams that want a shared build environment with pooled credits.

Less suited to

• Anyone who needs a fixed monthly bill, since Agent usage and hosting can exceed the included credits.
• Large production systems needing custom infrastructure and strict engineering control.
• Developers who prefer a local editor, where Cursor or GitHub Copilot fit better.

How to get started

1. Sign up for the free Starter plan and describe a small app in one clear paragraph.
2. Review what the Agent builds and test it as a user would before asking for changes.
3. Keep an eye on how many credits each request uses.
4. Check security basics, such as keys and logins, before you publish anything real.
5. Move to Core when you need more than the free daily credits and one published app.

Prompt ideas to copy

Build a simple habit tracker web app with user login. Users can add habits, tick them off each day and see a weekly streak. Use a clean, simple design.

Add a feature that emails me a daily summary of new sign-ups. Explain which service you used and what it will cost to run.

Review this app for security problems such as exposed keys or missing input checks. List them by severity and fix the top three.

Explain this code to a beginner, file by file, and suggest three improvements.

Limitations and things to watch

• Costs can rise quickly once credits are used up, especially with large Agent tasks and hosting.
• Generated apps still need testing, particularly for logins, payments and private data.
• Plans changed in February 2026, so older guides quote outdated prices.
• Check how you can export your code before you build something important.
