The short version
- Only Vitest has a free tier, so it costs nothing to try first.
- Each has a real cost: 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.; Vitest assumes Vite: projects on webpack or other bundlers lose the main advantage
- They diverge on capability: Tricentis Tosca covers Model based test design, Vitest covers Shares Vite config.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
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.
Vitest
- Assumes Vite: projects on webpack or other bundlers lose the main advantage
- Younger than Jest, so some plugins and matchers in the Jest ecosystem have no equivalent
- Jest compatibility is close but not exact, and unusual Jest configurations still need work to port

Answered from the vendors’ own pages
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.
Vitest: Is Vitest free?
Yes, open source under the MIT licence.
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.
Vitest: Is Vitest compatible with Jest?
The API is deliberately Jest-compatible and most migrations are mechanical, though unusual configurations and some ecosystem plugins need attention.
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.
Vitest: Do I need Vite to use Vitest?
It works without a Vite app but the main benefit — sharing one config and transform pipeline — only applies if you are already using Vite.
