NocoDB

NocoDB connects to your existing relational database — it does not own the data. You point it at a Postgres instance and it reflects every table as a NocoDB view, including data that other apps are writing to. Baserow and Airtable own their data in their own Postgres/proprietary store. This makes NocoDB the right choice when you need a no-code UI on top of a production app database, and Baserow the right choice when you are building a brand-new database from scratch.

NocoDB's AGPL-3.0 core is free to self-host with no row or user limits. Self-hosting on Docker takes about 5 minutes on any $5 VPS. The hosted nocodb.com cloud has a free tier with limits and paid tiers starting around $10/user/month. Enterprise plans add SSO, audit logs and dedicated support. The AGPL license means SaaS resellers must open-source their modifications, which is a common reason large companies pick enterprise licensing.

Retool and Appsmith are internal-tool builders — you compose UIs from drag-drop widgets and write SQL/JS. NocoDB is a database-first UI: it gives you tables, views and forms without writing any UI code. For 'I need a spreadsheet on top of my Postgres', NocoDB is faster. For 'I need a custom admin dashboard with charts and approval workflows', Retool or Appsmith are stronger. Many teams use both: NocoDB for data ops, Retool for custom dashboards.

The PWA shell installs offline but NocoDB depends on a live database connection for all operations. For offline-tolerant scenarios, host NocoDB on a local server alongside the database — useful in retail, field-ops and air-gapped industrial environments where everything sits on a LAN.

NocoDB respects database-level permissions when you connect with a least-privilege user. For production, use a read-only or schema-scoped Postgres role for read-heavy dashboards, and a write role only for tables that should be edited via NocoDB. The enterprise edition adds row-level and column-level access controls. Always run NocoDB behind a VPN or SSO for any non-public deployment.
