The short version

  • Only Kong has a free tier, so it costs nothing to try first.
  • Each has a real cost: Kong the Plus plan includes 1M API requests a month and charges $200 a month for each additional million; Tricentis Tosca licensing is quoted per workstation at enterprise figures, so the tool only pays back where testing headcount is already large; a team of five will not recover the cost.
  • They diverge on capability: Kong covers API Gateway, Tricentis Tosca covers Model based test design.
  • 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.

Kong

  • The Plus plan includes 1M API requests a month and charges $200 a month for each additional million
  • Plus is capped at 10M requests a month, so growth past that forces an Enterprise contract
  • Plus limits published APIs to 20 and includes one Developer Portal, with a second at $200 a month
  • SSO and audit logging are Enterprise only
  • Enterprise pricing is custom and billed annually

Tricentis Tosca

  • Licensing is quoted per workstation at enterprise figures, so the tool only pays back where testing headcount is already large; a team of five will not recover the cost.
  • Building the initial application model takes months and is usually done with paid consultants, meaning value arrives long after the invoice does.
  • The authoring environment is Windows only and heavy, which sits awkwardly in organisations whose engineers work on macOS or Linux.
  • Tricentis has assembled its portfolio through acquisitions, so products sold together vary in how deeply they are integrated and a buyer should verify the joins rather than the diagram.
  • Skills are specific to Tosca and not transferable, so recruiting testers means hiring for a niche tool and losing a trained one hurts more than losing a Selenium engineer.
