System & Network Tests
Review your public IP address, browser-exposed device details, browser capabilities and real internet speed measurements with transparent limitations.
Device Information
View browser-exposed device, screen, touch, language, timezone and online status information.
Browser Information
Check browser family, platform, storage, cookies, JavaScript, WebGL, WebGPU and API support.
What Is My IP?
Check the public IP address and coarse request location seen by the server, with one-click copy and clear privacy notes.
Internet Speed Test
Measure ping, jitter, download and upload speed with a sustained browser-based network test.
What these system & network tests cover
System and network tools show only information a browser or the current web request can legitimately expose. The speed test performs real network transfers; device and browser pages avoid pretending they can read hidden hardware details.
When to use these tests
Use this group to check your public IP, browser capabilities, screen/device signals, or to compare ping, download and upload performance under the same network conditions.
Tips for more consistent results
For speed comparisons, disable VPNs unless you intend to measure the VPN path and test near the same time of day. Public IP geolocation is approximate and can reflect your ISP or VPN exit point.
