The short version
- Only APITable has a free tier, so it costs nothing to try first.
- Each has a real cost: APITable records are held in the product own schema rather than as native database tables, so the practical row ceiling is a product limit and large tables should be load tested before commitment.; 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.
- They diverge on capability: APITable covers API first design, Coefficient covers Scheduled refresh.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
APITable
- Records are held in the product own schema rather than as native database tables, so the practical row ceiling is a product limit and large tables should be load tested before commitment.
- The hosted free tier caps records per space, so evaluating on the cloud version gives a misleading picture of what the software can do when self hosted.
- Automation is thin compared with the commercial alternatives, and most real workflows end up in an external automation tool.
- The self hosted deployment is heavier than a single container, so running it properly means managing several services rather than one.
- Documentation and community activity are uneven in English, and finding an answer to an operational problem can take longer than the problem itself deserves.
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.

Answered from the vendors’ own pages
APITable: What is the record limit?
The self hosted edition has no product cap, but performance is bounded by the internal schema rather than by your database. Test at your expected size.
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.
APITable: Can I embed it in my own product?
Yes, and that is the main reason to choose it. Views embed and the widget SDK extends them.
Coefficient: Does it write data back?
Yes, to supported systems such as Salesforce. Confirm with your data governance team before enabling it.
APITable: Is the hosted version representative?
No. Its free tier caps records per space, which is a commercial limit rather than a technical one.
Coefficient: Is there a free tier?
Pricing is not published in a form that can be quoted reliably. Ask the vendor before budgeting.
APITable: How hard is self hosting?
Harder than a single container. Plan for several services and someone to keep them running.
Coefficient: Does it work in Excel?
Yes, across both Google Sheets and Microsoft Excel with the same connectors.
APITable: Does it do automations?
Lightly. Expect to pair it with an external automation tool for anything multi step.
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.
