Bolt.new
Browser-based app builder that runs a full Node.js environment via WebContainers.
+ Runs npm, dev servers, and builds entirely in the browser so nothing is installed.
− Token-metered pricing burns through the monthly allowance on larger projects.

+ Built-in integrations for AI models, Stripe, and databases without API wiring.
− Smaller community and fewer templates than Lovable or v0.
+ Supabase auth, database, and edge functions are wired up without any configuration.
− Credits run out fast when debugging, since every fix attempt costs a message.
+ Backend, user management, and hosting are all included, so there is nothing to connect.
− Limited code export and less customisation than Lovable or Bolt.
+ Hosting, database, auth, and secrets live in one place, so deployment is a button.
− Effort-based billing makes costs unpredictable and the agent has deleted user data in a notorious incident.
+ Produces a real Python backend, which suits data-heavy and API-heavy apps.
− Slower and pricier per build than front-end-only builders.
