Every company keeps two copies of its business logic: a document people read and code that runs. They drift. GoRules keeps one copy. Rules read like sentences, live in visual graphs or policy documents, and ship with reviews, releases, and tests. The open-source ZEN engine (MIT, Rust) answers your API, your agents, and your batch jobs in about 10 microseconds. An AI copilot builds and explains rules; people release. Cloud, self-hosted, or embedded.

    The pricing of GoRules.io might be on the higher side for small businesses or startups with limited budgets, which could be a potential barrier to entry.
  • Complexity for Non-Technical Users
    While the interface is user-friendly, some complex rule configurations might still require technical understanding, posing challenges for non-technical users.
  • Limited Customization Options
    The platform may have constraints regarding customization, which can limit its flexibility to adapt to specific business requirements or unique use cases.
  • Learning Curve
    New users might experience a learning curve when getting accustomed to the platform's functionalities and optimizing its use for their business needs.
  • Dependence on Internet Connectivity
    Like many cloud-based solutions, GoRules.io requires a stable internet connection, and connectivity issues could interrupt access to the platform.

assertpy features and specs

  • Fluent API
    Assertpy offers a fluent API that makes assertions more readable and expressive, enabling developers to write assertions in a natural language style that is easy to understand.
  • Chainable Assertions
    It allows for chainable assertions, enabling multiple checks to be performed in a single line of code, thereby reducing verbosity and enhancing clarity.
  • Comprehensive Assertion Methods
    The library provides a wide range of built-in assertion methods, catering to various types of data validations, such as checking for size, type, value, and more.
  • Extensibility
    Assertpy supports extending its functionality by defining custom assertions, allowing developers to tailor it to their specific needs.
  • Pythonic
    Designed with Pythonic principles in mind, Assertpy fits seamlessly into Python projects, enabling idiomatic and consistent code style.

Possible disadvantages of assertpy

  • Learning Curve
    Developers new to the library may encounter a learning curve due to the distinct approach of using fluent and chainable assertions as opposed to traditional methods.
  • Limited by Python Version
    The library may have limitations in terms of compatibility with older versions of Python, requiring users to ensure their environment is up-to-date.
  • Performance Overhead
    The additional abstraction layer introduced by a fluent interface might introduce some performance overhead, especially in performance-critical or resource-constrained environments.
  • Less Community Support
    Compared to more established testing libraries, Assertpy might have less community support and fewer resources available for resolving issues or getting help.
  • Dependency Management
    Using a third-party library introduces additional dependencies to manage, which could complicate project maintenance and compatibility.

  • ๐Ÿš€ GoRules Zen Engine: Cross-platform rules engine written in Rust
    On a serious note: We bought gorules.io domain with initial plans for using GoLang, however after a while, the name stuck with us and our clients, and it felt difficult to go back on something we were used to. We don't associate GoLang with the engine, but we do plan support for it sometime soon (via FFI). Source: over 3 years ago
  • ๐Ÿš€ Introducing GoRules: Open-Source Business Rules Engine
    GoRules is a modern, open-source rules engine designed for high performance and scalability. Our mission is to democratise rules engines and drive early adoption. Rules engines are very useful as they allow business users to easily understand and modify core business logic with little help from developers.
