Spacebar Endurance Test
The spacebar endurance test measures your click stamina. You choose a target CPS (clicks per second), start pressing, and try to stay above that speed for as long as possible. The run ends once your CPS drops below the threshold for more than a brief grace period.
This mode is useful if you want to train for longer fights in games, stress-test your keyboard, or simply challenge yourself to keep a stable high CPS.
First tap/space starts the endurance run and counts as a press.

Spacebar Endurance Test FAQ
What do my endurance results say?
The endurance test is more about stamina than raw speed. You can think of your performance in two parts:
- Target CPS chosen: higher targets are harder to maintain
- Time survived: how long you kept your CPS at or above the target
As a loose guide:
- Surviving 30+ seconds at a low target (3-5 CPS) shows decent basic stamina
- Surviving 20+ seconds at a medium target (6-8 CPS) is strong
- Surviving 10+ seconds at a high target (9+ CPS) is very challenging for most users
If you constantly fail early at a given target, try lowering the target slightly and working up over time. A -good- endurance result is simply one where you can repeat a similar time several runs in a row without your hands feeling completely destroyed.
These ranges are approximate and meant only as rough guidelines.
What is the endurance test?
It is a stamina-based CPS test. You set a target CPS value, and the test measures how many seconds you can maintain a clicking speed at or above that threshold before you slow down.
How do I use it?
Pick a target CPS from the presets (3, 5, 7, 10, 12, 15) or select Custom to enter your own. Press the spacebar or tap the main button to start - your first press begins the timer. Keep pressing to maintain your CPS. If your current CPS stays below the target for longer than the built-in grace time, the run ends. Use Reset to cancel and start over.
How should I read the results?
After each run, you will see how long you lasted (time survived) and your average CPS across the run. The "Endurance results" table shows your most recent endurance attempts in this browser session so you can see which target values and techniques give you the best survival time.
Can I use this for gaming or training?
Yes. This mode is useful if you want to train for longer fights in games, stress-test your keyboard, or simply challenge yourself to keep a stable high CPS.
Does it work on mobile and with the mouse?
Yes. You can use the spacebar, mouse clicks on the button, or touch on mobile screens. The endurance logic does not care how you trigger the presses, so you can treat it as a mouse endurance CPS test or a mobile stamina test too.
How accurate is the timing and CPS?
The test uses millisecond timestamps to track press times and calculate CPS. That is accurate enough for personal training, keyboard testing and gaming warm-ups. Device, browser, and system differences can affect precision slightly, so it is best used for comparing runs on the same setup rather than as a lab instrument.
Is this tool free, safe, and local?
Yes. This tool is free and the core test logic runs in your browser. No account or installation is required, and we do not send your individual test results to our own database.
