Installs solely via npm without external libraries or software, as the README emphasizes 'generate captcha without install any other libraries'.
Generates captcha images at 1204 per second, making it suitable for high-traffic web applications needing fast response times.
Offers a straightforward API with a get() method returning both text and image buffer, reducing implementation complexity for basic captcha needs.
Allows configuration of width, height, spacing, quality, font size, and custom text functions, providing flexibility in captcha appearance.
Only supports JPEG on Linux and BMP on Windows/macOS, with the README explicitly warning against production use on non-Linux systems.
Requires compiling C++ code during installation, which can fail without proper gcc versions (v4.8+ on Linux) and adds setup overhead.
The README has typos and unclear instructions, such as 'compile maybe cost you 1 minute,simply wait;', making it challenging for developers to troubleshoot.
