# Browser Debugging Utilities


Device info, network info, key codes, microphones, cameras, JavaScript playgrounds, and browser-side testing.

This guide is the canonical guide page for related tools on ilham.dev. It should grow into practical explanations, caveats, examples, and references instead of creating one thin article per utility.

## Notes for future edits

- Keep the guide reusable and factual.
- Link to personal posts only when there is a real incident, measurement, migration, or lesson.
- For sensitive inputs, mention whether the related tool runs locally in the browser and warn against pasting production secrets without understanding the trust boundary.
