The short version
Replit is one of the most capable places to build software with AI. Its agent writes the code, sets up the database and login, and publishes the app, and the code is yours. That power comes with the work of running software, and with hosting that's billed separately.
Crevio is built for selling, not software. The store, checkout, courses, memberships, email list, and hosting come in one plan, and AI bots keep running the marketing and follow-up after launch.
Which one should you pick?
If you're building a software product, especially one that needs custom code or a mobile app, pick Replit. If you're selling something and want the business run for you, pick Crevio.
