TestDriver vs mabl

From $20 per seat/month (120 testing minutes included, then $0.14/minute)

Quote on request

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.

Quote-based, typically sold as an annual contract sized by test runs and users. Expect mid five figures for a team deployment.

Free trial rather than a standing free tier; paid seats include 120 testing minutes a month.

14-day free trial.

• 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.

• Self-healing genuinely reduces maintenance on UIs that change often.
• Auto-captured visual, performance and accessibility signals on every run without extra setup.
• Very little infrastructure to own — no grid, no runners.

• 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.

• Cloud-only. If your application is not reachable from mabl's infrastructure, the setup gets complicated.
• Complex conditional logic hits the ceiling of the low-code model.
• Opaque pricing and a substantial minimum commitment.

Teams testing extensions, desktop apps or canvas-heavy UIs, where selector-based runners simply cannot see the thing under test.

Mid-market teams that want broad automated coverage without hiring an automation team.
