Baserow

Baserow is an open source database and low-code app builder built on PostgreSQL that emphasizes data ownership and self-hosting. It supports real-time collaboration on spreadsheets and forms, carries SOC 2 and HIPAA compliance certifications, and offers GDPR guarantees for those running it self-hosted. The database-first architecture means you build apps around structured data, rather than designing UI first and wiring the backend later.

Baserow works best for teams that want to own their data infrastructure or need strong compliance guarantees, and for building database-backed internal tools and workflows. Compared to Airtable or Retool, Baserow's open source nature gives you transparency and hosting flexibility, though its ecosystem of integrations and professional templates is smaller. For teams already comfortable with PostgreSQL, the self-hosted option provides both cost control and full deployment ownership.
