TestDriver vs Tricentis Tosca
Feature checklists rarely decide anything. What decides it is the pricing metric, who has to write the tests, and which limitation you can live with.

The metric that actually scales your invoice.
The seat price is the small half of the bill: $20 per seat covers 120 testing minutes, then metering kicks in at $0.14 a minute (about $8.40 an hour). Seats are billed for every GitHub user who gets a PR review or runs a test, and a vision model driving a desktop is slower per test than a headless browser — model the minutes before committing a large suite.
Enterprise licensing only, negotiated annually. Six-figure contracts are normal at scale.
Free tier
Free trial rather than a standing free tier; paid seats include 120 testing minutes a month.

Strengths
- Tests surfaces nothing else reaches — browser extensions, packaged desktop apps, canvas and third-party OAuth screens.
- No selectors to maintain, so a refactor that renames every class breaks nothing.
- Runs per pull request in a disposable sandbox rather than against a shared staging environment.
- Unmatched coverage of enterprise packaged software, especially SAP end-to-end processes.
- Model-based design means one change updates every affected test case.
- Risk-based prioritisation is a real answer to eight-hour regression packs.
Limitations
- A vision model is non-deterministic. Reruns of an unchanged test do not always take the same path, which makes a genuine failure harder to distinguish from a bad frame.
- Billed by testing hours, and driving a real desktop is slow — a suite that costs pennies on Playwright can cost real money here.
- Young product with a small community; expect to be an early reporter of your own bugs.
- Expensive, and priced for organisations with a procurement department.
- Steep learning curve; most customers buy consulting alongside the licence.
- Heavy and slow compared to modern code-first tools for plain web applications.
Best for
Teams testing extensions, desktop apps or canvas-heavy UIs, where selector-based runners simply cannot see the thing under test.
Large enterprises running SAP or similar packaged systems where no open-source tool reaches.
