Compare Airtable alternatives
Airtable popularized the spreadsheet-meets-database interface, but it's closed-source and cloud-only, with row limits and collaboration features gated behind paid plans — there's no way to self-host it or run it on your own infrastructure.
Baserow and NocoDB both replicate Airtable's spreadsheet-as-database interface and are free to self-host. NocoDB's particular strength is turning an existing SQL database into an Airtable-style interface, which is worth knowing if you already have data living in Postgres or MySQL rather than starting from scratch.
