Open Source No Code Platform
The promise of a visual builder is shipping an internal tool in an afternoon, but the bargain underneath decides whether that speed lasts: most platforms meter you per user and keep the app inside their cloud, so a quick admin panel turns into a per-seat bill you can't take with you. The open source builders here let you drag together the same forms, tables, and dashboards over your own database, then run the result on infrastructure you control, so the tool and its data stay yours rather than rented by the head.
