The short version

  • Only Mathesar has a free tier, so it costs nothing to try first.
  • Each has a real cost: Coefficient google Sheets is capped at ten million cells per spreadsheet, so a wide dataset exhausts the sheet in the low hundreds of thousands of rows no matter how much data the source holds.; Mathesar there is no hosted offering of any kind, so a team without someone who can run and secure a server cannot use it at all.
  • They diverge on capability: Coefficient covers Scheduled refresh, Mathesar covers Direct PostgreSQL editing.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Coefficient

  • Google Sheets is capped at ten million cells per spreadsheet, so a wide dataset exhausts the sheet in the low hundreds of thousands of rows no matter how much data the source holds.
  • Write back from a spreadsheet into a system of record bypasses the validation and audit trail that system was given, which many data governance teams will refuse outright.
  • Pricing is not published, so it cannot be compared against alternatives without a sales conversation, and per seat costs across a whole revenue operations team add up quickly.
  • Every refresh runs a query against the source, so an aggressive schedule across many sheets consumes warehouse credits or Salesforce API calls that are billed elsewhere and easily overlooked.
  • It keeps analysis inside spreadsheets, which entrenches the sprawl of untracked business logic that a business intelligence tool or a semantic layer would have consolidated.

Mathesar

  • There is no hosted offering of any kind, so a team without someone who can run and secure a server cannot use it at all.
  • It works only with PostgreSQL, so a MySQL, SQL Server or SQLite estate is excluded outright.
  • There are no automations, no webhooks and effectively no integration catalogue, so it edits data and does nothing else.
  • Because it writes to the live database, a careless bulk edit or column type change is a production change with no staging step and no undo.
  • Development is grant and community funded rather than commercially funded, so roadmap pace and long term continuity carry a different risk profile from a venture backed vendor.

Answered from the vendors’ own pages

Coefficient: How much data can I actually pull in?

Google Sheets allows ten million cells per spreadsheet in total. Divide by your column count for the real row limit.

Mathesar: Is there a cloud version?

No. Self hosting is the only option, and that is a deliberate project decision rather than a gap waiting to be filled.

Coefficient: Does it write data back?

Yes, to supported systems such as Salesforce. Confirm with your data governance team before enabling it.

Mathesar: How does it handle permissions?

Through PostgreSQL roles and privileges directly, so there is no second permission model to keep in step.

Coefficient: Is there a free tier?

Pricing is not published in a form that can be quoted reliably. Ask the vendor before budgeting.

Mathesar: What is the row limit?

Whatever PostgreSQL can handle. Mathesar adds no storage layer of its own.

Coefficient: Does it work in Excel?

Yes, across both Google Sheets and Microsoft Excel with the same connectors.

Mathesar: Does it support databases other than PostgreSQL?

No.

Coefficient: What is the hidden cost?

Warehouse query credits and source API calls consumed by scheduled refreshes, which are billed by those vendors and not by Coefficient.

Mathesar: Can it replace Airtable?

Only for editing and exploring data. There are no automations, apps or integrations.
