What teams are saying
Early users are shipping schemas faster and with fewer production migrations.
“We replaced three whiteboarding sessions with a single AI prompt. The generated schema was 90% there, and the visual editor handled the rest.”
“The multi-format import saved us a week of hand-converting a legacy MySQL schema into our new Postgres setup. Everything just mapped.”
“Finally a schema tool that doesn't feel like a 2010 Java applet. Shareable links mean our PMs can actually read the data model.”
