The short version

  • Only Rowy 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.; Rowy every Firestore limit is inherited, including the one megabyte per document ceiling and roughly one sustained write per second per document, which surprises users who expect spreadsheet behaviour.
  • They diverge on capability: Coefficient covers Scheduled refresh, Rowy covers Firestore backed grid.
  • 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.

Rowy

  • Every Firestore limit is inherited, including the one megabyte per document ceiling and roughly one sustained write per second per document, which surprises users who expect spreadsheet behaviour.
  • Firestore has no joins, so linking tables in the grid is a convenience layer rather than a relational feature and reports across collections still need a separate query.
  • It is useful only to teams already on Firebase, so choosing it effectively locks the operational tooling to one cloud vendor.
  • Query costs are billed by document read, and an unfiltered grid on a large collection can generate a bill that a spreadsheet user has no intuition for.
  • Development activity has slowed relative to the broader category, so evaluate current maintenance before making it load bearing for internal operations.

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.

Rowy: Where is my data stored?

In your own Firestore instance inside your own Google Cloud project. Rowy does not hold a copy.

Coefficient: Does it write data back?

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

Rowy: What does it cost to run?

No licence fee. You pay Google Cloud for Firestore reads, writes, storage and function invocations, and an open grid on a big collection reads a lot.

Coefficient: Is there a free tier?

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

Rowy: Can it do joins across collections?

Not really. Firestore does not support joins, and no interface layer can add them.

Coefficient: Does it work in Excel?

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

Rowy: Is there a row limit?

Not from Rowy. The limits that bite are Firestore document size and per document write throughput.

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.

Rowy: Is it suitable if I am not on Firebase?

No. It is specifically a Firestore interface.
