A browser-based YouTube enhancer versus a free, open-source Mac website blocker with a timer. Which one fits your platform and goals?
SelfControl is beautifully simple — set a timer, add sites, and you’re locked out. No way to cheat. Clify is equally focused but on the opposite goal: making YouTube better instead of blocking it. SelfControl is Mac-only and blocks entire sites; Clify works on any browser and enhances YouTube.
Below is a detailed side-by-side breakdown of what each tool offers.
| Feature | Clify | SelfControl |
|---|---|---|
| YouTube ad blocking | Yes | — |
| YouTube Shorts removal | Yes | — |
| SponsorBlock integration | Yes | — |
| Block websites | — | Yes |
| Timer-based blocking | — | Yes |
| Cannot be undone | — | Yes |
| Cross-device sync | — | No |
| Audio equalizer | Yes | — |
| Price | Free forever | Free |
| Open source | Yes | Yes |
| Platform | Browser | Mac only |
Both tools are free and open source, but they take opposite approaches. SelfControl blocks entire websites with an unbreakable timer. Clify enhances YouTube by removing specific distracting elements. One removes access; the other removes friction.
SelfControl is a free, open-source Mac application that does one thing extremely well: it blocks websites for a set time period. You add websites to a blocklist, set a timer, and click Start. Once the timer begins, you cannot access those sites — and you cannot undo it, even by restarting your Mac, deleting the app, or changing your system clock.
The app is beautifully simple. There are no accounts, no subscriptions, and no cloud sync. You download it, install it, and use it. The blocklist and timer are the only settings. This simplicity is both its greatest strength and its limitation.
SelfControl is Mac-only and has been around for years. It is one of the most respected open-source productivity tools in the Mac ecosystem. However, it has no YouTube-specific features — it blocks entire sites rather than modifying their content.
Clify takes a fundamentally different philosophy. Instead of blocking YouTube entirely, Clify enhances it. It is a free, open-source browser extension that removes the parts of YouTube that waste your time and add clutter, while keeping the content you actually want.
Specifically, Clify removes YouTube advertisements (including mid-roll video ads), strips out YouTube Shorts from the interface so you do not fall into the infinite scroll, integrates with SponsorBlock to automatically skip sponsor segments in videos, and provides a built-in audio equalizer for better sound quality. All of this runs entirely in your browser, with no account required.
The key insight is that YouTube is not inherently bad. It hosts incredible educational content, tutorials, documentaries, and creative work. The problem is the engagement-maximizing design around that content: ads, Shorts, and sponsor segments that pull you away from what you came for. Clify addresses the actual problem instead of throwing the baby out with the bathwater.
SelfControl excels when you need a simple, unbreakable website block on your Mac. Here are the scenarios where it is the right choice:
The trade-off is that SelfControl is Mac-only and treats all content equally. If you need YouTube for work, you either block it completely or leave it completely open. There is no middle ground.
Clify fills a gap that SelfControl ignores entirely. If your main digital distraction is YouTube but you still need YouTube for productive purposes, Clify is the better tool.
The limitation is clear: Clify does not block distracting websites or apps outside of YouTube. If your procrastination extends to Reddit, Twitter, and Instagram, Clify will not help with those.
Both SelfControl and Clify are free and open source, making them rare examples of fully transparent productivity tools. You can inspect exactly what each application does and verify that there are no hidden data collection or tracking mechanisms.
SelfControl’s block is truly unbreakable. Even deleting the app, restarting your Mac, or changing your system clock will not bypass it. Once a session starts, the only way to end it is to wait for the timer to expire.
SelfControl is Mac-only, while Clify works in any Chromium-based browser on any platform. If you use Windows or Linux, Clify is the only option of the two that is available to you.
Yes. They serve different purposes and can complement each other. You could use SelfControl to block distracting sites like social media on your Mac while using Clify to clean up your YouTube experience in your browser. This combination gives you both system-level blocking and YouTube-specific enhancement.
No. SelfControl is a Mac-only application. It is built specifically for macOS and has no Windows or Linux version. If you need website blocking on Windows, you would need a different tool. Clify, however, works in any Chromium-based browser on any operating system.
No. SelfControl’s block is designed to be truly unbreakable. Even restarting your Mac, deleting the app, changing your system clock, or modifying your hosts file will not bypass the block. Once a session starts, the only way to end it is to wait for the timer to expire. This is what makes SelfControl so effective for people who cannot trust their own willpower.
It depends on your needs. If you need unbreakable website blocking on your Mac, SelfControl is one of the best tools available — free, open source, and impossible to bypass. If you use YouTube for productive purposes and want to remove the distractions while keeping the platform, Clify is the better choice. Many Mac users find that using both together works best — SelfControl for blocking distracting sites and Clify for enhancing YouTube.
