Selenium Grid vs TestingBot
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.

Strengths
- No per-session licensing — parallelism is limited only by your compute budget.
- Runs inside your network, so private environments and data never leave.
- Fully under your control, including browser versions.
- Transparent pricing and no enterprise sales process.
- EU-based, which simplifies some data-residency conversations.
- Responsive support relative to company size.
Limitations
- You own the operations: scaling, browser image updates, flaky node debugging.
- No real iOS or Android devices, and no Safari without macOS hosts.
- No built-in video, analytics or dashboards without extra tooling.
- Smaller device and browser matrix than the leaders.
- Fewer adjacent products — no visual testing or analytics suite.
- Small vendor risk for critical infrastructure.
Best for
Organisations with platform engineering capacity and either scale or data-residency constraints.
European small and mid-sized teams wanting a no-nonsense grid at a fair price.
All of these integrate with: Selenium, Jenkins.
