The New Choice for HttpClient Tool

Currently, popular Http Client Tools on the market include Postman and Insomnia. While they are versatile, they have the following drawbacks:

• Both are developed based on JavaScript, resulting in slow startup speeds. When dealing with a large number of requests, the interface may become sluggish.
• Due to the cloud-oriented design of such software, there are inherent security risks, making them less suitable for use in high-security environments.
• Commercial purposes are evident, with many convenient features requiring payment.

In response to these issues, we have developed Postcat as the next-generation HttpClient tool. It is built using Rust as the programming language, benefiting from Rust's cross-platform capabilities and Egui's immediate rendering mode. Postcat demonstrates excellent performance, with almost negligible opening times. The initial core installation package is only 3MB in size, and even with the addition of built-in fonts and deno-core, the package size remains under 30MB.

With Postcat, you can:

• Debug APIs using the most popular protocols and formats.
• Test APIs using JavaScript.
• Build CI/CD pipelines for testing using the native Postcat CLI. (Coming soon)
• Collaborate with others on your project using Git.

Your projects, collections, specifications, and all other files support the following storage options:

• Workspaces: Easily switch between multiple workspaces, each isolated from the others.
• Git Sync: Workspaces support Git synchronization, organizing file storage at the granularity of APIs, reducing the likelihood of conflicts during modifications.
• No involvement with remote server storage ensures the safety of your data.

And there's more!

• Support for importing data from Postman. We also plan to support data import from Insomnia.
• Real-time rendering of environment variables, allowing you to immediately see the results of environment variable operations.
• Introduction of deno-core as the JavaScript runtime, providing comprehensive support for ES6.

Currently, Postcat supports all features of HTTP requests, and its operations are almost identical to Postman. Tests using deno-core fully support ES6 syntax and event loops.

Of course, Postcat still has its limitations. Being relatively new, it lacks extensive testing, and its features may not be as robust as those of established tools. We welcome everyone to try it out and provide valuable feedback.
