Proprietary SaaS app builder; closed source. (GPT Engineer, its open source predecessor, is a separate legacy repo; the scored product is the proprietary Lovable platform.) The product site is no longer fetchable - lovable.dev answers 403 to a non-browser request - so the claim rests on Lovable's own documentation, which describes a hosted platform throughout: account creation, dashboard, enterprise tier, a managed Cloud backend, connectors, git sync and a managed npm registry, with no source distribution and no self-host path.

Lovable reports millions of projects built, around 8 million users and $400M ARR at about 146 employees, which puts usage in the 1-10M band. The user total carries no period, so it is neither a download count nor an active count, but the level is the same on either reading.

  Lovable crossed $400 million in ARR in February, confirmed to TechCrunch by the company, and has attracted "some 8 million users"
