Emisar is the last MCP server youโ€™ll need to install: a Zero-Trust gateway connecting Claude, Cursor, ChatGPT, and any AI agent to your infrastructure. One server handles production access, debugging, alerts, and internal operations, with new capabilities added as packs. Agents can inspect real production state, debug what they shipped, and help resolve incidents. Safe reads run automatically; policy allows, blocks, or routes risky actions for approval. No SSH keys, VPNs, remote shells, or standing shell access โ€” and every call is recorded.

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.

Analysis of Hack Lang

Overall verdict

  • Hack Lang is considered good for projects that require the balance of PHPโ€™s dynamic nature with the advantages of static typing. It provides a strong type system and useful modern features, making it a robust choice for developers familiar with PHP looking to optimize performance and code reliability.

Why this product is good

  • Hack Lang is an extension of PHP that was developed by Facebook to improve the efficiency, safety, and speed of their large codebase. It introduces static typing while still supporting PHP interop, which helps catch errors earlier in the development process. Hack Lang also includes features like collections, lambda expressions, and async programming, all of which are designed to modernize and enhance PHP development.

Recommended for

    Hack Lang is recommended for developers and large-scale organizations already using PHP who want to transition to a more modern and type-safe environment. It is particularly suitable for projects that require high performance and code maintainability, such as large web applications with complex business logic.

Questions & Answers

As answered by people managing Hack Lang and Emisar.dev.

How would you describe the primary audience of your product?

Emisar.dev's answer:

emisar is for SRE, DevOps, platform engineering, infrastructure, and security teams that want AI agents to inspect and operate production systems. It is especially relevant to teams managing multiple Linux hosts, clusters, databases, cloud services, or regulated environments where unrestricted shell access and incomplete audit records are unacceptable.

Which are the primary technologies used for building your product?

Emisar.dev's answer:

The hosted control plane and operator interface use Elixir, Phoenix, LiveView, PostgreSQL, and Tailwind CSS. The host runner and MCP bridge are written in Go. Action packs use YAML and JSON Schema, while production infrastructure is managed with Terraform on Google Cloud. The system communicates through MCP, OAuth 2.1, TLS, and WebSockets.

Who are some of the biggest customers of your product?

Emisar.dev's answer:

  • Blitz.gg - game analytics for billions of matches and a pretty large infrastructure.

What's the story behind your product?

Emisar.dev's answer:

Founder Andrii Dryga spent a decade working as a CTO, full-stack engineer, SRE, and DevOps engineer. He experienced the cost of running the wrong command on the wrong cluster, while also seeing AI solve operational problems in seconds. emisar grew from the need to preserve both truths: AI agents are useful, and production access must remain bounded. Its answer is to give agents a reviewed catalog of operations instead of a blank terminal.

What makes your product unique?

Emisar.dev's answer:

emisar lets AI agents work on real infrastructure without giving them a shell. Agents choose from a finite catalog of typed, versioned actions. Policy decides what runs, what requires approval, and what is denied, while an outbound-only runner verifies the action again on the host. New capabilities arrive as packs behind the same MCP integration, and every request is recorded in both a searchable audit trail and a tamper-evident host journal. [

Why should a person choose your product over its competitors?

Emisar.dev's answer:

Choose emisar when you want an agent to keep investigating and handling routine operations without handing it SSH credentials or supervising every call. Compared with raw shell access, copy-paste workflows, or one-off MCP servers, emisar provides reviewed action contracts, host-level enforcement, risk-based policy, scoped access, approvals, pack integrity checks, and a durable audit trail. It is built specifically for governed infrastructure access rather than generic automation.

Hack Lang mentions (21)

  • 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
