Both are free, both target Windows, and both are massively popular — but the differences in speed, footprint, and safety are bigger than most people realize. Here's the full comparison.
If you've searched for a free Windows auto clicker in the last decade, you've seen both names. OP Auto Clicker and GS Auto Clicker are the two most-downloaded free auto clickers for Windows — but they're built differently and serve different users.
Short answer: OP Auto Clicker is faster, smaller, open source, and portable. GS Auto Clicker is the older project with a more conventional installer and a slightly easier UI for first-time users. The full comparison is below.
Every spec that matters, in one table.
| OP Auto Clicker | GS Auto Clicker | |
|---|---|---|
| Maximum CPS | 100+ CPS | 30–50 CPS |
| Minimum interval | 1 ms | 10 ms |
| Installation required | No (portable) | Yes (installer) |
| File size | 512 KB | ~5 MB installer |
| Open source | Yes (GitHub) | No |
| Bundleware in installer | None | Historically yes |
| Code-signed | Yes | Varies |
| Custom hotkey | Any key | Any key |
| Fixed-position click | Yes | Yes |
| Click count limit | Yes | Yes |
| Single & double click | Yes | Yes |
| Telemetry / analytics | None | Unknown (closed) |
| Windows 11 verified | Yes | Yes |
| Price | Free | Free |
| Last updated | 2024 | Older release cadence |
Honest pros and cons for both.
If you need 100+ CPS — Minecraft PvP, Roblox sims at max gain rate, drag-clicking benchmarks — OP Auto Clicker is roughly 2–3× faster.
USB stick, sandbox, locked-down work PC, school computer — OP runs without admin rights or registry writes.
Open-source code on GitHub, no bundleware, no telemetry, code-signed releases.
If you've used GS for years and don't need higher CPS, there's no urgent reason to switch.
Some users prefer Start Menu entries and an uninstall flow. GS provides that; OP doesn't.
Same hotkey behavior, similar configuration UI, similar Windows compatibility.
OP Auto Clicker hits 100+ CPS with a 1ms minimum interval and is open source. GS Auto Clicker tops out around 50 CPS with a 10ms minimum and isn't open source. Both are free for Windows.
GS Auto Clicker is generally safe but is not open source — its installer has historically bundled optional third-party offers. OP Auto Clicker is a cleaner alternative: open source, no bundleware, no installer.
OP Auto Clicker is faster. It supports a 1ms minimum interval (theoretical 1,000 CPS) vs GS Auto Clicker's 10ms floor (100 CPS theoretical). In real-world tests OP sustains 100+ CPS, GS sustains 30–50 CPS.
OP Auto Clicker is 512 KB and runs portably. GS Auto Clicker requires a 5+ MB installer that writes to the registry and adds Start Menu entries.
No. They are separate, independently developed Windows auto clickers. Both are free, but they have different authors, source code, feature sets, and distribution models.
Match your use case to the right pick.
| If you... | Pick | Why |
|---|---|---|
| Need 100+ CPS for Minecraft PvP | OP Auto Clicker | GS caps around 50 CPS |
| Run from a USB / locked-down PC | OP Auto Clicker | Portable, no admin needed |
| Want to audit the source code | OP Auto Clicker | Open source on GitHub |
| Have used GS for years and don't need higher CPS | GS Auto Clicker | No urgent reason to switch |
| Want a Start Menu shortcut + uninstaller | GS Auto Clicker | OP is portable, no installer |
| Need to avoid bundleware risk | OP Auto Clicker | No third-party offers in installer |
| Run Roblox clicker simulators at 40 CPS | OP Auto Clicker | Tighter timing at higher CPS |
| Need a tiny binary for a sandbox | OP Auto Clicker | 512 KB vs 5 MB |
| Want code-signed releases | OP Auto Clicker | Signed since v2.5 (2022) |
Five-minute migration. Settings carry over conceptually.
Write down your GS Auto Clicker interval, click type, and hotkey.
Settings → Apps → uninstall GS Auto Clicker. Reboot if prompted.
Set the same interval, click type, hotkey. The OP Auto Clicker UI is similar — takes 30 seconds.
