I see a lot of comments about people who are worried that Google might shutdown the service entirely and I agree with your concerns. The last months we have seen a lot of giants building their own database spreadsheet like hybrid, Google Tables, Microsoft Lists and Amazon Honeycode. Tools like these contain your most important data and you want to have freedom, security and independence as they can be an important part of your business.
Because of these reasons I started Baserow (https://baserow.io), which is an open source (https://gitlab.com/bramw/baserow) alternative to Airtable and the listed tools above. It is still in an early phase, but every week new features are implemented.
Some unique points:
- Unlimited rows.
- Open source, released under the MIT license.
- Uses popular frameworks like Django and Nuxt.js
- Uses PostgreSQL as database backend.
- It can be self hosted.
- You can have many rows per table, 100k+.
- Headless and API first.
- Supports plugins.
