In one line: Replit Agent turns a description like "a booking page for my dog-walking business" into a working app with a database, then publishes it to a live link, with a free Starter plan (daily Agent credits, Lite build only, one published app that goes down after 30 days) and paid plans from $18 a month billed yearly.
What it is
Replit started as an online code editor and is now mostly an AI app builder. You type what you want in the prompt box and Replit Agent plans it, writes the code, sets up a database and shows you a preview you can click through. You keep going in plain English ("add a sign-up form", "the button is broken on mobile") until it works, then publish it to a live URL from the same place. Agent has three modes: Free Mode, which uses an included allowance and lets Replit pick the model, plus Power Mode and Max Mode for bigger or harder jobs, which spend your monthly credits (Replit warns you before a request switches to a paid mode). Paid plans add Plan Mode, where Agent helps you map out the work without touching your code, connectors to services like Google and Stripe, and other kinds of projects such as slide decks, data visualizations and animated videos. There's also a Design Canvas for trying visual ideas before you build.
Who it's for
Founders testing an idea, small business owners who need a simple internal tool or booking page, and product managers or designers who want a clickable prototype without waiting on engineers. It also suits people who can code a little and want the hosting, database and publishing handled in one place. If you mostly want a polished front end and are happy to bring your own backend, Lovable (issue #9) is the closer comparison. If you'd rather keep an AI coding agent in your own terminal and repo, OpenCode (issue #2) is that.
Try this today
Go to replit.com and sign up for the free Starter plan. Pick something small you'd actually use, and describe it in one paragraph with the who, the what and one rule, for example: "A page where clients pick a 30-minute slot from my weekday availability and enter their name and email. Show me the list of bookings on a separate admin page." Leave the mode on Free, let Agent build it, then test it like a stranger would: book a slot, refresh, and check the admin page. Ask Agent to fix whatever breaks, one problem per message. When it works, publish it and send the link to one friend. Check Settings → Usage afterward to see how much of your allowance that took.
The catch
The free plan is a real test drive but a short one. Starter gets daily Agent credits up to a monthly cap and only Lite build, the quick-edit mode; Full build, where Agent works more independently, needs Core. You get one published app, and that link goes down after 30 days, with a "Made with Replit" badge on it. Connectors to outside services, Plan Mode and the extra project types are paid too. On paid plans the bigger risk is cost creep: Power and Max Mode draw from monthly credits, and Replit bills pay-as-you-go once those run out, so set a spending limit before a long build session. Agent can also make mistakes (Replit says so on its own pricing page), so test anything that handles customer data or payments before you share it.
