Replit Agent review

Replit Agent is the most capable builder here for apps that need more than screens and a form. You describe the app, and the agent builds it inside Replit's workspace with a built-in database and authentication, plus connections to services like Stripe and OpenAI where your keys stay stored securely. The feature that sets it apart is self-testing: while building, the agent opens the app in a browser, writes a report and fixes what it finds, which Replit says is 3x faster and 10x more cost effective than computer use models. It can also build agents and automations that run in Slack or email. Pricing starts with a free Starter plan that publishes one app, and Core is $18 a month billed annually with $20 toward stronger models. The limits are real, though: Full build mode and Plan Mode need Core, and the next tier, Pro, is $90 a month billed annually.
