Pound

Pound sits in front of one or more backend web servers and handles their HTTPS. The manual documents the poundctl management client and the optional Lua extension. Pound is installed by building it from a source tarball or a git clone, and building it needs OpenSSL. Once started, it detaches from the controlling terminal and serves requests.

Worth knowing

The code was first written at Apsis GmbH, which discontinued the project in 2022. The current maintainer continued it from a fork, and the README says Pound is not a web server, although its special backends can serve static files.
