Please, what is the maximum number of rows and columns available in the Glide table? And how can I build an app, such that the data is stored locally by the users of the app?

The number of rows depends on the plan you are building:

- 25k for spreadsheet data sources: Glide Tables, Google Sheets, Excel, Airtable
- Millions for high-scale data sources: Glide Big Tables, SQL

I’ve heard of some creators have Glide tables with 300+ columns. There probably is a limit, or a least a number of columns where performance goes down, but that limit is probably quite high.

As far as I understand how Glide works, data cannot be stored locally by the users. Instead, data is stored on Glide’s servers and syncs with the end device of users and external data sources. Something like this:

- Basic columns: end user’s device ↔︎ Glide’s servers (incl. Glide Tables & Glide Big Tables) ↔︎ external sources (Google Sheets, Airtable, etc.)
- Computed columns: the data is not stored but computed on the end user’s device
