Methodology
What We Measure
Each benchmark provisions a headless browser session, connects over CDP, navigates to a target page, and releases the session, measuring the time for each phase independently.
Five metrics are captured per iteration: create, connect, navigate, release, and total end-to-end latency.
Each provider is tested with 100 iterations per run. Benchmarks run automatically via GitHub Actions on a recurring schedule. All results are committed to the public benchmarks repo.
How We Score
The Composite Score is a weighted blend of total-latency percentiles and create latency, multiplied by the success rate. Latency is scored against a fixed 10-second ceiling: 100 × (1 − value / 10,000ms).
The weighted score is multiplied by the success rate (0–1), so providers that fail frequently are penalized proportionally.
- • Total median: 40%
- • Create median: 30%
- • Total P95: 20%
- • Total P99: 10%
