  • No pricing published on website; requires contacting AdaCore directly for quotes
  • Vendor indicates per-user, per-year subscription model but does not disclose specific costs

Lovable

  • Credit-metered rather than unlimited: Free plan gets 5 build credits/day capped at 30/month, plus 20 cloud-hosting credits/month and 4 AI-feature credits/month
  • Credits expire: monthly plan credits expire after 2 months unused, annual-plan credits expire 1 month after the annual period ends, and all credits are non-refundable
  • Not open source; only the legacy precursor CLI gpt-engineer is open source (MIT), and that repo was archived read-only on 2026-04-22
  • Hosting is free only for smaller apps; significant traffic or size draws additional charges from the credit balance
