Keyboard Tester is a browser-based utility that lets you evaluate your keyboard’s performance. Test key response, detect latency, check key conflicts (rollover), and measure typing speed & accuracy. No installation or registration required.
Key Features
- Key Test: press individual keys to verify they register correctly
- Latency Test: measure how fast the keyboard responds when prompted
- Conflict (Rollover) Test: press multiple keys at once to see which combinations work and whether there are ghosting issues
- Typing Test: check typing speed (WPM) and accuracy using standard text
- Download or share results of typing test
Use Cases
| Scenario | Why It’s Useful |
|---|---|
| Gaming | Ensure fast response and correct key rollover for fast combinations |
| Hardware Diagnostics | Identify unresponsive keys or conflicting signals |
| Typing Improvement | Measure speed and accuracy gains over time |
| Purchasing Decisions | Compare different keyboards based on measurable performance |
| Professional Work | Make sure keyboard behaves reliably for code, writing, data entry |

- Use Latency Test: wait until the signal/tracker prompts, then press a key to measure reaction time
- Use Conflict / Rollover Test: hold several keys down simultaneously to see which are registered and whether there are conflicts
- Use Typing Test: type the given sentence for a fixed time to get speed, accuracy, character count; download/share if desired
Advantages
- Instant diagnostics without downloads or setup
- Covers multiple performance aspects: latency, rollover, typing speed & accuracy
- Works on many keyboard types (mechanical, membrane, wireless) via browser
- Helps identify both visible and subtle keyboard issues
FAQ
What is key rollover / conflict detection?
It tests whether multiple keys pressed at the same time are all correctly recognized (important for gaming or fast typing).
What is considered good latency?
Lower is better. Excellent is under ~5ms, good 5–15ms, moderate 15–30ms. Higher than that may feel laggy.
Is this tool free?
Yes. The tool is free and doesn’t require creating an account.
Does it work with wireless keyboards?
Yes. Wireless, mechanical, membrane keyboards should all work; detection happens via browser input.
Can I save or share the test results?
Yes. You can download or share results from the typing test portion.
