Hi, Iโ€™m Boris, co-founder of AppStruct โ€” a new no-code platform built for web, mobile, and desktop apps development. Weโ€™re a team of no-code enthusiasts who set out to fix the two biggest pain points we kept running into: speed and complexity.

Weโ€™re not the first to build in the no-code space โ€” but we felt the idea has never been pushed to its full potential. So we started fresh and built AppStruct from the ground up with one goal in mind:

Combine powerful functionality with simple UX โ€” and make app creation faster than ever.

  • Five Years of json-tool and 3,000 Active Users Later
