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.; Weka the package management system needs an internet connection to download and install packages, so an air-gapped install gets only the core distribution
  • They diverge on capability: APITable covers API first design, Weka covers Classification.
  • 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.

  • An internal platform where tables are read and written mostly by code through the API and only occasionally by peoplenot Weka
  • A self hosted replacement for a per seat spreadsheet database where seat count is the cost drivernot Weka

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.

Weka

  • The package management system needs an internet connection to download and install packages, so an air-gapped install gets only the core distribution
  • Weka is split into a stable 3.8 branch that receives only bug fixes and compatibility-safe upgrades and a 3.9 development branch that may receive features that break compatibility
  • Weka requires a 64-bit Java VM; the bundled installers ship Bellsoft OpenJDK 25 per platform and architecture

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.

Weka: What is the cost of Weka software?

Weka is provided at no cost as open-source software released under the GNU General Public License, making it freely available for download and use.

Source
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.

Weka: Are there commercial licensing options available?

Yes, the project offers information about commercial licenses for organizations requiring non-GPL terms, which can be found in their commercial applications documentation.

Source
APITable: Is the hosted version representative?

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

Weka: What support resources are available to users?

Multiple support avenues exist including comprehensive documentation, frequently asked questions, dedicated help resources, and access to courses for learning the platform.

Source
APITable: How hard is self hosting?

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

Weka: Is source code access provided?

Yes, developers have full access to source code through the Git repository, along with development documentation and code credits for contributors.

Source
APITable: Does it do automations?

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