Yes. The code of all 6 is public under AGPL 3.0, Apache 2.0, MIT or GPL 3.0, so you can use them with no licence fee. Running one yourself costs the server and your time to look after it, and some makers also sell a hosted plan.

Start from the job you use Airtable for. Choose AITable.ai when you want open source code you can run and change yourself. Choose Baserow when you want to host it yourself and keep your data on your own server.

AGPL 3.0 (2), MIT (2), Apache 2.0 (1), GPL 3.0 (1). MIT, BSD and Apache let you change and reuse the code freely. GPL and AGPL ask you to share your changes under the same licence when you give the software to others, and AGPL also counts letting people use it over a network.

The hosting. Airtable's maker runs the servers for you; with an open source tool the updates, backups, security fixes and support are yours, unless you take the maker's hosted plan. Features differ too, so check what each one imports and exports before you move your data.
