Speed Test History
Every test you run is saved locally so you can compare results over time and export them — your private, on-device record.
Your saved results
Stored privately in this browser. Results from the speed tools land here automatically.
Why keep a test history?
A single test is a snapshot. A history is evidence. Connection problems
are often intermittent — worse in the evening, or only when the line is
busy — so one good reading proves nothing and one bad reading is easy to
dismiss. By keeping a dated record of every test you run, you can spot
patterns (slower at peak hours, spikier on Wi-Fi than wired) and build a
timeline you can show your ISP. Everything here is stored locally in your
browser under the key std_history;
nothing is uploaded, and you can export or clear it any time.
How to use it
- 1. Run any speed tool — ping, jitter, packet loss, bufferbloat or stability. Results save here automatically.
- 2. Repeat at different times of day and on Wi-Fi versus cable to surface patterns.
- 3. Press Export to download a JSON record for your files or for your ISP.
Frequently asked questions
- Where are my results stored?
- Entirely in your browser, in local storage on this device. Nothing is uploaded to a server and nothing leaves your machine. That also means your history won't follow you to another browser or device.
- Which tools save to my history?
- The ping, jitter, packet loss, bufferbloat and long-run stability tests all save a result automatically when they finish. Run any of them and come back here to see the entry.
- How do I keep a permanent copy?
- Use Export to download your full history as a JSON file. It's perfect for keeping a dated record — for example, evidence to share with your ISP when your connection misbehaves.
- Will clearing my browser data delete this?
- Yes. Because results live in local storage, clearing site data or browsing in private mode will remove them. Export first if you want to keep them.
