Enter a public URL. The audit measures load and Core Web Vitals. Read LCP and CLS. Fix your own site from the notes.
You work in English (US) on this page. Labels are in plain words. If a control is optional, the page says so. You can ignore optional boxes on the first run.
What Website Speed Test is not
Website Speed Test is not a hosted backend for your company. It is not legal advice. It is not a place to store customer databases. Use it for samples, teaching, and quick jobs.
When a Website Speed Test run is worth your time
Use Website Speed Test when you need website speed test in a browser and you can review the output yourself.
- You are on a laptop that blocks random installers.
- You want to show a teammate the click path on a call.
- You need a second opinion before you change production data.
- You are learning website speed test and want a safe sandbox.
Skip Website Speed Test when the file is classified, when a policy forbids web tools, or when you need a signed SLA.
Also skip it when the job is a million rows. Browsers freeze. Split the work. Or use a script you own after Website Speed Test taught you the settings.
URLs, files, and tokens to have ready
Have these nearby before you click Run test.
- A tiny sample named speed_test_sample_47. Keep it under a few kilobytes if you can.
- A note of the encoding or delimiter your source system uses.
- A place to save output, such as a folder named speed test out.
- A second device or phone if you must scan a QR or read an OTP.
- The Privacy Policy if the sample includes personal data.
If you cannot redact names, stop. Make a fake sample. Website Speed Test still teaches the clicks. Fake data is easier to share in tickets.
Open Website Speed Test in your browser
Go to https://devswallet.com/tools/speed-test. Confirm the heading says Website Speed Test.
If you landed on a category page, use search. Type website speed test. Open the card. Bookmark the tool URL, not a search result, so you do not grab the wrong cousin tool.
DevsWallet also lists this write up at https://devswallet.com/blog/speed-test. Keep both tabs: one for the tool, one for this guide.
Check your browser zoom. The layout is built for a normal desktop width. A very small phone works for tiny jobs. Large files prefer a computer.
Run Website Speed Test without guesswork
Do this in order. Do not skip the tiny sample even if you feel busy.
- Enter the URL, two texts, or the payload Website Speed Test asks for.
- Set method, headers, or device type if those fields exist.
- Click Run test.
- Read the status, the timing, or the highlighted diff.
- Write down one action. Example: compress a hero image, or fix a 401 header.
If the page spins
Worker tools (PDF, OCR, speech, video) need time. Stay on the tab. If it fails, shrink the file. Then retry once. Three retries with the same huge file waste the afternoon.
One retry, then shrink the file
If Website Speed Test fails twice on the same huge input, the file is the problem. Cut speed_test_sample_47 down, click Run test again, then grow the job.
If you need a teammate
Send the tool link https://devswallet.com/tools/speed-test plus your sample name speed_test_sample_47. Do not send production passwords.
A Website Speed Test case study you can repeat
Pretend you are helping a US teammate named Alex. Alex has a file called speed_test_sample_47. The goal is website speed test before lunch.
Run the tiny sample first
You open Website Speed Test. You paste only the first record or the first page. You click Run test. You get a result you can explain in two sentences.
Write those two sentences in the ticket. Example: "I ran Website Speed Test on speed_test_sample_47. Output matched the number 42 and the date 2026-03-12." That is a useful note. "It worked" is not.
Then run the real file
Then you run the full file. If the full file fails, you already know the tool path is fine. The data is the issue.
Keep speed_test_sample_47 in a folder of golden samples. Next month, when Website Speed Test gets a UI tweak, you re run the same file. That is how you avoid surprises.
How to read the Website Speed Test panel
Here is a compact map of Website Speed Test. Labels may shift slightly, but the jobs stay the same.
| Control | What it is for | Note |
|---|---|---|
| Target | URL or two texts | Required |
| Method / flags | GET vs POST, etc. | Match production |
| Inspector | Status, timing, diff | Write one follow up |
If a control is missing, you are on a smaller screen. Open the advanced row. Or rotate the phone. Do not assume a missing box means the feature is gone.
