Butterbase is a backend, and its complaints are about the free tier and metering. Playground projects pause after a week of inactivity, the plan is limited to 1 project and only $1 of one-time AI usage, and paid plans bill overage on storage and bandwidth. An account is required, and the docs and privacy URLs returned the homepage when we checked.
Lovable turns prompts into working web apps with a credit-based model; it has a free tier, but no starting price is stated in our data. Replit goes further by building and hosting the app from a chat: Core is $20 per month and a free tier exists. Cursor is an editor rather than a hosted backend, so you bring your own database and hosting; Individual (Pro) is $20 per month with usage-based billing and a free Hobby tier. Butterbase stays the narrower fit if your assistant is already working over MCP and you only need Postgres, auth and storage.
