Hack Lang features and specs

  • Static Typing
    Hack adds static typing to PHP, which helps catch type-related errors early and improves code quality and maintainability.
  • Async Programming Support
    Hack has built-in support for asynchronous programming, making it easier to write non-blocking, high-performance applications.
  • Compatibility with PHP
    Hack is designed to be compatible with existing PHP code, making it easier for developers to transition from PHP to Hack without completely rewriting their codebase.
  • Type Annotations
    With type annotations, developers can specify the types of variables, return types of functions, and parameter types, which leads to more readable and self-documenting code.
  • Collections API
    Hack provides a rich collections API, which includes various data structures like Vector, Map, and Set, making it easier to work with data in a type-safe way.
  • Integrated Development Environment (IDE) Support
    IDE tools like HHVM and Hack development environments provide robust support for Hack, offering features such as autocompletion, real-time type checking, and error detection.

Possible disadvantages of Hack Lang

  • Limited Ecosystem
    Hack does not have as large an ecosystem of libraries and frameworks as PHP, which might limit third-party integrations and available resources.
  • Learning Curve
    For developers coming from PHP or other dynamically-typed languages, there is a learning curve associated with the static typing and other advanced features of Hack.
  • Facebook Dependency
    Hack was developed by Facebook and is heavily associated with their infrastructure. This can lead to concerns about its future direction being tightly controlled by a single company.
  • Deployment Complexity
    Deploying Hack applications often requires the HipHop Virtual Machine (HHVM), which can add complexity to the deployment process compared to traditional LAMP stack setups.
  • Community Support
    Compared to more established languages like PHP, Hack has a smaller community, which may result in fewer tutorials, forums, and community-driven support options.
  • Performance Overheads
    While HHVM improves performance for PHP and Hack code, there can still be situations where performance tuning and optimization are necessary to achieve the desired performance.

  • PHP Almost Generics: Guided Journey Through the Official Compile-Time Proposal
    I'm glad that PHP has adopted more and more from Hack, Facebook's once fork and now completely separate language - https://hacklang.org/. It was never going to replace it (Go's success separate from Google has astounded me to be honest) but it heavily influencing PHP's direction feels like the best of both worlds. - Source: Hacker News / 10 months ago
  • Upcoming Hardening in PHP
    Doesnโ€™t Facebook still run most of their backend on Hack[0] (compiled PHP subset)? [0] https://hacklang.org/. - Source: Hacker News / over 1 year ago
  • PHP is the new JavaScript?
    What ever happened to Hack (https://hacklang.org) the language Meta built as a superset of PHP? Why not take an approach more similar to TypeScript? I sometimes do wonder if many of the server side rendering approaches (or alternative Node runtimes) would be better off trying to emulate some aspects of PHP. - Source: Hacker News / almost 2 years ago
  • Javascript Ecosystem, How Trash It Actually Is?
    On top of all that, now we want to make JavaScript type-safe. So let's add 10 more configuration files, add a compiler, and now we have bullcrap^2. Just like Facebook invented HackLang, Microsoft invented TypeScript, but only companies of this magnitude need such features. The average Joe from Delaware does not need all that. - Source: dev.to / about 2 years ago
  • Benchmarking 20 programming languages on N-queens and matrix multiplication
    PHP results: Is Hack still popular with PHP people? I was stupid enough to write some scientific code in PHP once so know how slow it can be. But if your going to do try write performant code in PHP use the HHVM interpreter. It's much faster. Hack (https://hacklang.org/) uses that under the hood by default. - Source: Hacker News / over 2 years ago

  • Best Cloud Monitoring Tools in 2026: A Developer's Honest Comparison
    Better Stack bundles uptime monitoring, incident management, on-call scheduling, log management, and status pages into one dashboard. For cloud monitoring, it sits closer to the external/uptime layer than to deep infra telemetry. It watches your cloud-hosted endpoints, collects logs, and gives you on-call and a status page without stitching together separate products. - Source: dev.to / 5 days ago

  • Best Synthetic Monitoring Tools in 2026: Honest Comparison
    Better Stack bundles uptime, real Playwright/Chromium browser checks, incident management, on-call, logs, and status pages in one product โ€” and its native on-call and escalation are the best in this list.

  • Best Status Page Software in 2026: Honest Comparison for Engineering Teams
    Better Stack (formerly Better Uptime + Logtail) is the most ambitious all-in-one in this list โ€” it bundles uptime monitoring, on-call scheduling, incident management, status pages, AND log management into a single platform. If you want one vendor for your entire observability and incident communication stack, this is the closest thing to that vision. - Source: dev.to / about 1 month ago
