Classic ASP,
without the OS lock-in.
OpenASP brings a Classic ASP interpreter and resident runtime to Linux, Unix and MacOS. Keep your existing `.asp` business code and leave the Windows Server and IIS dependency behind.

THE OPEN ASP RUNTIME
Bring legacy code to
modern infrastructure.
Implemented in pure C11, OpenASP compiles ASP templates and includes into validated bytecode and provides standalone rendering, a persistent interactive environment, multi-process FastCGI, shared bytecode caching and an optional OAC disk cache. The current version is 0.1.0.
02
Complete tools and deployment
Use openasp, openasp-cli, openasp-dis, openasp-dbg and openasp-fpm for rendering, interactive execution, disassembly, debugging and FastCGI deployment.
See supported platforms →03
AI, data and extensions
Connect databases, caching and AI through OpenASP.MySQL, OpenASP.Redis and OpenASP.OpenAI, with native SQLite, MDB, Memcache, HTTP/WebSocket, JSON, XML and cryptography.
Join the project →UP AND RUNNING
Launch your
first ASP app in three steps.
Install the Linux x86-64 or MacOS Apple Silicon package, or build from source, then render ASP pages directly or start the FastCGI service.
Read the full docs ↗01
Install OpenASP 0.1.0
Download the package for your platform, or install a C11 compiler and dependencies before running `make all` and `make test`.
02
Run existing ASP pages
Render a page with openasp and point `--root` to the physical site root; the persistent CLI, debugger and OAC disassembler are also included.
03
Start FastCGI
Start openasp-fpm and let Nginx, Egret-web-server or another gateway forward `.asp` requests; enable the shared opcode cache in production and keep shell and process execution disabled.
$ openasp-fpm --root /srv/www/example --host 127.0.0.1 --port 9000 --workers 4 --opcache-memory 64

BUILT FOR THE LONG RUN
From Windows servers,
