Pros

- ✔No vendor lock-in
Cons
- ✕Self-hosting needs technical setup
- ✕Smaller ecosystem than Airtable
- ✕Fewer polished integrations
For Airtable users whose main gripes are per-seat cost and cloud lock-in, Baserow is the clearest answer: it's open source and self-hostable, so you can run it on your own server for free and own your data outright. The interface is a familiar spreadsheet-database, and there's a hosted cloud option if you'd rather not run infrastructure. The trade-offs are the usual open-source ones — self-hosting takes technical setup, the integration ecosystem is smaller than Airtable's, and some polish is missing. But for a team that values ownership and wants to escape per-user pricing, Baserow is a compelling, no-lock-in switch. CSV/Airtable import is supported.
