Baserow is itself already open source — its core is MIT licensed, free to self-host, and covers most of what most teams need for a no-code database and app builder, with paid tiers reserved for premium and enterprise features like advanced automations and support.
Since Baserow is already open, the useful comparison is to other open-source spreadsheet-database tools rather than an "escape the proprietary vendor" pitch. NocoDB is a direct open-source alternative if you want to compare feature sets or connect to an existing SQL database rather than Baserow's own managed Postgres backend.
