SelfControl features and specs

  • Effective Website Blocking
    SelfControl blocks access to distracting websites based on a customizable blocklist, helping users stay focused.
  • Timer Functionality
    Users can set a timer for how long they want websites to remain blocked, ensuring focused work periods without distraction.
  • Free to Use
    SelfControl is open-source and free to download and use, making it accessible to anyone without financial barriers.
  • Easy to Use
    The interface is straightforward and user-friendly, allowing users to quickly set their preferences and get started.

Possible disadvantages of SelfControl

  • Mac-Only
    SelfControl is only available for macOS, excluding Windows and Linux users from using the application.
  • No Undo Option
    Once the block period is set and started, it cannot be undone even by restarting the computer, which could be an issue if access to blocked sites is needed unexpectedly.
  • Limited Feature Set
    The app primarily focuses on website blocking, lacking additional productivity tools or features like app blocking or usage analytics.
  • No Scheduled Blocking
    SelfControl does not offer the ability to schedule block sessions in advance, meaning users must manually start each session.

Crystal (programming language) features and specs

  • Performance
    Crystal is designed to have the performance of C, thanks to its compilation to efficient native code. Its static type system and low-level memory management capabilities allow optimized execution.
  • Syntax
    Crystal offers a syntax that is heavily inspired by Ruby, making it intuitive and familiar for Ruby developers. This can significantly reduce the learning curve and improve developer productivity.
  • Type Inference
    Crystal provides powerful type inference, enabling developers to write less boilerplate code while still benefiting from the safety and performance of a statically-typed language.
  • Concurrency
    Crystal supports lightweight concurrency with fibers, which allows developers to write efficient and scalable concurrent programs with a simpler syntax compared to traditional threading models.
  • Community and Ecosystem
    Crystal has an active and growing community. It also boasts a rich ecosystem with libraries and tools, making it easier for developers to find resources and support.

Possible disadvantages of Crystal (programming language)

  • Maturity
    Crystal is still a relatively young language compared to more established languages like Python or Java. This can mean fewer resources, libraries, and tools, as well as potential instability in certain areas.
  • Compilation Time
    Crystal's compilation times can be slower compared to interpreted languages, particularly for larger codebases. This can impact development workflows and iteration speed.
  • Binary Size
    Compiled Crystal programs tend to generate larger binary sizes compared to other compiled languages like Go or Rust. This can be a consideration for resource-constrained environments.
  • Platform Support
    Being less mature, Crystal may have fewer options for platform-specific optimizations and integrations, which could limit its use in certain specialized applications.
  • Tooling
    Although the situation is improving, Crystal's tooling ecosystem is not as mature as those of older languages. This can affect the availability and quality of IDE support, debugging tools, and other development aids.

Really hard to bypass this even if you know networking stuff - iOS: Enable downtime 24/7 ask someone else to set the password.

  • My 30-Year Quitting Addiction
    There is a free and open source app called SelfControl for macOS. It allows one to block access to any site one adds to the list in the app for the amount of time the user chooses. Attempt to use multiple browsers, restarting one's machine, deleting the app, etc. won't get around the block either. It's been super helpful for me, so I thought I'd just throw it out there. https://selfcontrolapp.com. - Source: Hacker News / over 2 years ago

  • Ruby for Good
    Which can include type assertions but also a lot more. The agents seem to do well with this. I've also had good results using agents to write Crystal https://crystal-lang.org/ which is Ruby-like but does have the static types and produces blazing fast static binaries. Might be a sweet spot for coding agents if you're building some backend services. But I'd still pick Ruby on Rails for a new full stack project. - Source: Hacker News / about 2 months ago
  • Ask HN: What Are You Working On? (May 2026)
    Sounds a lot like Crystal, which is also similar to Ruby and features a green fiber runtime: https://crystal-lang.org/#concurrency. - Source: Hacker News / 2 months ago
  • A Grand Vision for Rust
    > 1. Go with a better type system. A compiled language, that has sum types, no-nil, and generics. I was looking for something like that and eventually found Crystal (https://crystal-lang.org) as a closest match: LLVM compiled, strong static typing with explicit nulls and very good type inference, stackfull coroutines, channels etc. - Source: Hacker News / 4 months ago
