• Transparent pricing and no enterprise sales process.
• EU-based, which simplifies some data-residency conversations.
• Responsive support relative to company size.

• 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.

• Smaller device and browser matrix than the leaders.
• Fewer adjacent products — no visual testing or analytics suite.
• Small vendor risk for critical infrastructure.

• 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.

European small and mid-sized teams wanting a no-nonsense grid at a fair price.

Organisations with platform engineering capacity and either scale or data-residency constraints.
