The short version

  • Only Selenium has a free tier, so it costs nothing to try first.
  • Each has a real cost: Selenium flaky tests are the standing complaint: explicit waits and synchronisation are the tester’s job, where newer tools handle it automatically; 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: Selenium covers W3C WebDriver, 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.

Selenium

  • Flaky tests are the standing complaint: explicit waits and synchronisation are the tester’s job, where newer tools handle it automatically
  • Setup involves drivers, versions and grid infrastructure that Playwright and Cypress bundle away
  • Slower to run than tools that talk to browsers over a debugging protocol rather than WebDriver

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.

Answered from the vendors’ own pages

Selenium: Is Selenium free?

Yes, open source with no licence fee. Paid costs come from grid infrastructure or services like BrowserStack.

Tricentis Tosca: Is Tosca scriptless?

Test assembly is scriptless, but non trivial estates still need TQL queries and custom modules, which is programming under another name.

Selenium: Selenium or Playwright?

Playwright handles waiting automatically and is faster to set up, which removes most flakiness complaints. Selenium wins on language breadth, browser coverage including Safari, and existing suites you already have.

Tricentis Tosca: Why does it dominate SAP testing?

It holds SAP certification, covers SAP GUI and Fiori at transaction level, and is sold through the same integrators that run SAP programmes.

Selenium: Is Selenium still relevant?

Yes. Its WebDriver protocol is a W3C standard implemented by every major browser, and very large existing suites are not rewritten cheaply.

Tricentis Tosca: Can it replace Selenium for a web only product?

It can, but the economics do not work. Model based testing pays off across large heterogeneous estates, not one web application.
