Summary

asp-classic-emulator is an open-source tool that allows developers to run ASP Classic (VBScript) applications on macOS, Linux, and BSD without needing Windows, IIS, or a virtual machine. It provides a high-fidelity HTTP server that interprets VBScript with full support for the ASP object model, SQLite/MySQL/PostgreSQL databases, and uses a hand-written Chevrotain parser. The tool aims to help developers maintain legacy ASP Classic codebases on modern POSIX systems with zero configuration.

ASP Classic never died — it just got stranded on Windows.
Millions of lines of VBScript are still running in production, and maintaining them means either keeping a Windows Server around or setting up a VM every time someone needs to touch the code.
Drop it into any folder with .asp files, run one command, and get a fully working HTTP server that interprets VBScript with high fidelity to the original IIS behavior — on any POSIX system.
Zero config — works out
Snippet from the RSS feed
