Hack vs Phalcon: What are the differences?
What is Hack? A programming language for HHVM that interoperates seamlessly with PHP. Hack provides instantaneous type checking via a local server that watches the filesystem. It typically runs in less than 200 milliseconds, making it easy to integrate into your development workflow without introducing a noticeable delay.
What is Phalcon? Web framework delivered as a C-extension for PHP. Phalcon is a web framework implemented as a C extension offering high performance and lower resource consumption.
Hack belongs to "Languages" category of the tech stack, while Phalcon can be primarily classified under "Frameworks (Full Stack)".
"Interoperates seamlessly with php" is the primary reason why developers consider Hack over the competitors, whereas "Fast" was stated as the key factor in picking Phalcon.
Phalcon is an open source tool with 9.71K GitHub stars and 1.77K GitHub forks. Here's a link to Phalcon's open source repository on GitHub.
Sellsuki, Learning Data, and Ringostat are some of the popular companies that use Phalcon, whereas Hack is used by Facebook, Slack, and Wizters. Phalcon has a broader approval, being mentioned in 28 company stacks & 13 developers stacks; compared to Hack, which is listed in 8 company stacks and 3 developer stacks.

Throughout 2016, Slack began migrating from PHP5 to Hack. They cite several well-known challenges inherent to PHP, including surprise type conversions, inconsistency around reference semantics, inconsistencies in the standard library, and the fact that “PHP tries very, very hard to keep the request running, even if it has done something deeply strange.”
To overcome these challenges while maintaining the unique values of PHP, Slack turned to Hack, a gradual typing system for PHP. Hack runs on the HipHop Virtual Machine, or HHVM, an open source just-in-time (JIT) environment for PHP.
Since the beginning, Cal Henderson has been the CTO of Slack. Earlier this year, he commented on a Quora question summarizing their current stack.Apps
- Desktop: And Electron to ship it as a desktop application.
- Android: a mix of Java and Kotlin.
- iOS: written in a mix of Objective C and Swift.
- The core application and the API written in PHP/Hack that runs on HHVM.
- The data is stored in MySQL using Vitess.
- Caching is done using Memcached and MCRouter.
- The search service takes help from SolrCloud, with various Java services.
- The messaging system uses WebSockets with many services in Java and Go.
- Load balancing is done using HAproxy with Consul for configuration.
- Most services talk to each other over gRPC,
- Some Thrift and JSON-over-HTTP
- Voice and video calling service was built in Elixir.
- Built using open source tools including Presto, Spark, Airflow, Hadoop and Kafka.
'm a professional web developer from Vietnam with B.S Physics and Engineering. I'm a Phalcon enthusiast as Opensource. In free time, I was support on forum Phalcon also my forum and contribution core Phalcon.
I think precompiled PHP is the way to go. It saves CPU cycles, RAM and overall I/O. It saves money too. Smaller requirements = smaller bills.
I've tried symfony and zend. Phalcon was easiest to use.
