TestLap started from a familiar situation: standing in a shop with a used laptop in your hands, wanting to check it properly, but with no software available and no clear idea of what to look for.
So every tool here runs directly in the browser: nothing to download, nothing to install, no account. Just open the page on the machine you want to test.
Our principles
- Private: webcam images, microphone audio and the keys you press are processed inside your browser. There is no server receiving data. You can go offline after the page loads and keep testing.
- Plain language: every tool comes with a "what counts as a fault" section written for non-technical readers, including which issues are acceptable and which mean walking away.
- Honest: benchmark scores and thresholds are compiled from public sources, with the source and update date stated.
What these tools cannot do
A browser cannot read CPU temperature, drive health or exact battery wear. For those we publish guides to dedicated software with instructions on reading the results.
