Description
Casbin is a versatile open-source library designed for authorization, enabling the implementation of various access control paradigms such as Access Control Lists (ACL), Role-Based Access Control (RBAC), and Attribute-Based Access Control (ABAC). This library is available in numerous programming languages, including Golang, Java, C/C++, Node.js, JavaScript, PHP, Laravel, Python, .NET (C#), Delphi, Rust, Ruby, Swift (Objective-C), Lua (OpenResty), Dart (Flutter), and Elixir, ensuring developers have a unified API experience across different environments. By utilizing the PERM metamodel, Casbin allows developers to define access control models through configuration files, making it easy to modify or upgrade authorization systems with minimal effort. It also provides a variety of policy storage solutions, compatible with databases such as MySQL, PostgreSQL, Oracle, MongoDB, Redis, and AWS S3, catering to diverse storage needs. Additionally, Casbin includes a role manager that efficiently manages RBAC role hierarchies and supports filtered policy management, which enhances the effectiveness of access enforcement. As a result, developers can easily adapt Casbin to their specific project requirements while maintaining robust security practices.
Description
Featureflip offers a flat-rate pricing model that stands as an alternative to LaunchDarkly, Split, and Flagsmith, catering specifically to small teams who prefer not to incur escalating costs with each new hire. Unlike most competitors that charge based on the number of seats or monthly active users, Featureflip maintains a single, fixed price across all its plans. Every tier, including the complimentary Solo plan—which operates in production without a trial expiry—includes features like rollouts, targeting, segments, kill switches, audit logs, and access to all 13 SDKs. Users can conveniently disable features without redeploying via kill switches, implement percentage rollouts, and utilize rule-based targeting based on user attributes or segments. Additionally, the platform facilitates A/B testing through multi-variation flags and boasts sub-millisecond evaluation times, ensuring that server SDKs can evaluate in-process and maintain functionality even during outages. Featureflip supports a comprehensive suite of 13 SDKs, which encompasses JavaScript, Node, Python, .NET, Java, Go, PHP, Ruby, React, Browser, Swift, Flutter, and Android. Furthermore, every plan comes equipped with a REST Management API, Terraform provider, MCP server, and OpenFeature integration, enhancing usability and flexibility for diverse development needs. Overall, Featureflip aims to empower small teams with robust feature flag infrastructure without the burden of unpredictable pricing.
