undb

undb is a no-code platform that doubles as a backend for applications. Tables are managed through a browser interface, data sits in SQLite, and the same project can be one file on a laptop or a service running for a whole team, which removes the usual jump between a spreadsheet and a real backend.

Because the storage engine is SQLite, the whole thing stays light. Bun can package it into a single binary, or it runs as a Docker container listening on one port with a mounted volume for the data directory. A one-click Render deployment and a hosted cloud version cover the other end of the range.

Table management goes well past storing rows.

• Views: kanban, gallery, calendar and pivot layouts over the same underlying table.
• Forms: collect entries from people who never see the table behind them.
• Formula fields: calculated columns in the style of Excel or Airtable.
• REST API: an OpenAPI-described interface, which is what makes it usable as a backend service.
• Playground mode: try the product without setting anything up first.
• Progressive deployment: begin as a single local file and grow into a cloud stack later.

Local development needs Bun and a clone, with dependencies installed and a dev server started in two commands, or a Docker Compose file for the same result. The project calls itself private and local first, which is the appeal for anyone wanting Airtable-shaped tooling without their data leaving the building.
