Saltcorn: sovereignty score and 8 European alternatives

Saltcorn is an open-source no-code builder for database applications. On a relational data model with linked tables, you build views, pages and actions by drag and drop, with output as web, mobile, PDF or email. Workflows and actions continue running after failures, and an AI copilot builds pages and workflows from a description. Saltcorn is MIT-licensed and can be self-hosted, for example through npm, Docker or on a Linux server with PostgreSQL. A free multitenant instance runs at saltcorn.com, intended for exploring the product; according to the project there are no guarantees about security or availability.

Saltcorn Collective Ltd is registered in the United Kingdom, outside the EU. According to the website, the software runs without telemetry and can be placed behind your own firewall so that data stays on your own server. For a European organisation this means that self-hosting in an EU data centre gives full control over the data, while operations and security are then your own responsibility.

Why digital sovereignty matters with Saltcorn

Saltcorn is headquartered in GB, outside the EU. Contracts and data therefore also fall under non-European law. The GDPR applies through contractual terms, but in a conflict with local legislation you have less certainty than with a European vendor.

Data is hosted exclusively in the EU, so Saltcorn scores best on data residency.

Saltcorn is open source. You can audit the source code, self-host the software and keep the encryption keys under your own control. Switching is easier because data and software are not tied to a single party.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Saltcorn together with your other vendors and gives a total score, a heatmap and the main risk drivers.
