Use with care

Terms

Sketch Density Check is a free diagnostic aid, not a guarantee that every physical device will behave identically.

Permission

Use the CLI only on sketches and URLs you own or are authorized to test. You are responsible for network requests made by pages you choose to open.

Results

Frame and input measurements vary with hardware, browser version, temperature, power mode, extensions, and background load. Treat the publish card as reproducible evidence from one environment, not certification.

Software license

The software is provided under the MIT License, without warranty. The full license in the repository controls if this summary differs from it.

Changes

These terms may change alongside the project. Material changes will appear in the repository history. Last updated: 27 August 2026.
