#1 Baserow
Best for: Teams wanting a fully open-source, self-hostable Airtable alternative from an EU-registered company
- Operating company. Baserow B.V. (KvK 81129254)
- Jurisdiction. EU (Netherlands)
- Where the data sits. Germany (EU)
- Source code. MIT-licensed core, open-core premium features
Baserow started as a straightforward pitch: give teams the spreadsheet interface they already know, backed by a real database instead of a flat grid, published under MIT so nobody is locked into one vendor's cloud. Baserow B.V. is a Dutch B.V. registered in Amsterdam, and its €5M seed round in 2022 came entirely from European venture firms — INKEF Capital led it, with firstminute capital, Seedcamp and Frontline joining. No US institutional money appears in the cap table.
The product covers what an Airtable user expects — grid, gallery, kanban and calendar views, row-level permissions, a REST and webhook API, no-code automations — and Baserow's own documentation commits to hosting cloud customer data exclusively in Germany. The one inconsistency worth flagging: cloud pricing is listed in US dollars rather than euros, despite the company being Dutch.
What Baserow does well
- Dutch B.V. with only European venture investors on record
- Cloud data hosted exclusively in Germany, stated as policy
- MIT-licensed core, genuinely free to self-host with no row cap
- Direct Airtable-style feature set: multiple views, API, automations
Where Baserow falls short
- Premium views and automations require a paid licence even when self-hosting
- Cloud pricing listed in USD rather than EUR
- Free tier capped at 3,000 rows per workspace
Standout feature. Data residency stated as policy, not just as a default: cloud customer data is committed to Germany rather than left to whichever region happened to be nearest.
