The seat price is only part of it: CI execution needs add-ons priced separately — Runtime Engine at $145/licence/month and cross-browser or mobile device sessions at $158/session/month — so a parallel CI setup costs several times the headline seat figure.

Quote-based. Human-executed runs are billed separately from automated ones and are the expensive component.

• One tool spanning web, API, mobile and desktop, which avoids stitching four frameworks together.
• Manual testers become productive in days rather than months.
• Built-in reporting and test management reduce the number of separate purchases.

• The human fallback covers scenarios automation genuinely cannot reach.
• Anyone on the team can author a test.
• Results in minutes, integrated into the deployment pipeline.

• Record-and-playback suites become brittle at scale unless someone refactors them into keywords and objects.
• Proprietary project format makes migrating away expensive — real lock-in.
• Heavy desktop IDE; version control and code review are awkward compared to plain-text tests.

• Human runs get expensive quickly at any real frequency.
• Human testers lack product context, so results need interpretation.
• Web only.

QA teams without dedicated automation engineers that need coverage across several platforms.

Teams that need broad release-gate coverage including flows nobody wants to automate.
