The short version

  • 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.; 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: APITable covers API first design, Mathesar covers Direct PostgreSQL editing.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

APITable

  • Embedding an editable table view inside a product you are building, rather than sending users to another toolnot Mathesar
  • An internal platform where tables are read and written mostly by code through the API and only occasionally by peoplenot Mathesar
  • A self hosted replacement for a per seat spreadsheet database where seat count is the cost drivernot Mathesar
  • Building a custom dashboard widget that sits beside the data instead of in a separate reporting toolnot Mathesar

  • Giving analysts a safe editing interface governed by database roles that already existnot APITable
  • Replacing a hand built Django or Rails admin screen that nobody wants to maintainnot APITable
  • Editing production reference data where an export, edit and reimport cycle would risk losing concurrent changesnot APITable

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.

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

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.

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.

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.

Mathesar: How does it handle permissions?

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

APITable: Is the hosted version representative?

No. Its free tier caps records per space, which is a commercial limit rather than a technical one.

Mathesar: What is the row limit?

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

APITable: How hard is self hosting?

Harder than a single container. Plan for several services and someone to keep them running.

Mathesar: Does it support databases other than PostgreSQL?

No.

APITable: Does it do automations?

Lightly. Expect to pair it with an external automation tool for anything multi step.

Mathesar: Can it replace Airtable?

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