Open-source self-hosting as the top of the funnel, the cloud-hosted version as the paid tier — 21K GitHub stars carrying $9K MRR
Fewer bars = easier, cheaper, or faster for an AI-assisted solo builder. Editorial judgments based on the case details.
Jonathan is a developer and the co-founder of Chartbrew/ChartDB. The team originally wanted to build "a database client with AI," but it required users to hand over database credentials and install local software — too high a trust barrier, so nobody adopted it. They narrowed hard to "turn your database into a chart / ER diagram" — far more intuitive, a strong wow effect, and requiring neither credentials nor an install, so friction is minimal. GitHub has accumulated 21K+ stars, with roughly 250,000 developers using it a year.
