Apicat

What is Apicat?

Apicat is an open-source API client designed for developers who need to test and manage APIs offline. Unlike traditional tools that rely on cloud synchronization, Apicat stores all API requests and configurations as .http files locally on a developer's machine, making it well-suited for teams using version control systems like Git. Built with OpenAPI compatibility in mind, Apicat provides functionality similar to Postman while maintaining a lightweight, self-contained approach. The tool supports local file storage, allowing developers to commit API specifications and test cases directly into their repositories alongside code. This makes it particularly useful for teams that prioritize local-first workflows and version-controlled documentation. The project is completely open-source and free to use, with source code available on GitHub. Apicat targets developers who prefer offline-first solutions, work in Git-based environments, or need an alternative to cloud-dependent API testing tools. Its compatibility with Postman makes it accessible to users already familiar with that ecosystem while offering the advantage of local data storage and no dependency on external services. Apicat is suitable for individual developers, small teams, and organizations looking for a self-hosted, transparent, and git-friendly API testing solution.
