Base44 Free Plan (25 message credits + 100 integration credits per month)

The Free plan allows at most 5 messages per day and 25 messages per month in total, plus 100 integration credits per month, with an unlimited number of apps; the official page says the free plan has all core features (frontend, backend, database, user auth)

Official pricing page, Free card verbatim: "Free. All of Base44's core features, for free. See what you can build. 25 message credits … 100 integration credits", with the note "Credits are your monthly usage allowance for AI messages and integration actions. Exact usage varies based on the action and the selected AI model." FAQ verbatim: "The free plan gives you a daily allowance of 5 messages and a monthly cap of 25 messages total." "You can start building with Base44 for free, with every core feature included." "When you hit your monthly credit limit or want premium integrations, you can upgrade to a paid plan." The paid Starter plan has 100 message credits and 2,000 integration credits plus a free domain for 1 year; the Free card does not list a free domain.

⚠️25 message credits a month run out quickly, so it suits validating an idea. How many credits one message uses depends on the action and the chosen model, and the official page gives no conversion.
