Nginx and Apache support

The docs describe the Nginx handler as stable and commercially supported by Unbit, and say Apache's mod_uwsgi is stable and commercially supported.Read 8 Oct 2026 · uwsgi-docs.readthedocs.io

Nginx integration

The uWSGI module has been included in the official Nginx distribution since version 0.8.40, and the documentation calls the handler stable and commercially supported by Unbit.Read 8 Oct 2026 · uwsgi-docs.readthedocs.io

Operating systems

The supported systems page lists Linux, BSD variants, Windows Cygwin, Mac OSX, Solaris and several other Unix-like systems.Read 8 Oct 2026 · uwsgi-docs.readthedocs.io

Project status

The project is in maintenance mode, with bug fixes and updates for new language APIs; the project says not to expect quick responses to GitHub issues or pull requests.Read 8 Oct 2026 · uwsgi-docs.readthedocs.io

Resource controls

Linux cgroups can constrain CPU, memory, scheduling priority, and I/O, and the documentation says uWSGI must run as root to use cgroups.Read 8 Oct 2026 · uwsgi-docs.readthedocs.io

Security guidance

The documentation warns against exposing a uWSGI protocol socket to the public network because it allows dynamic application loading, and recommends a proxy or a loopback-bound socket.Read 8 Oct 2026 · uwsgi-docs.readthedocs.io

Subscription security

Subscription requests can be signed with public/private keys and the server rejects packets whose signatures do not verify; the docs describe this subsystem as intended for trusted networks.Read 8 Oct 2026 · uwsgi-docs.readthedocs.io
