Project Status

mod_wsgi is a mature project. It has been used in production by Python web applications for over 15 years and is functionally complete for typical Apache + Python WSGI deployments. Active work today is focused on polish, internal cleanup, and rounding out auxiliary capabilities rather than on changing the core hosting model.

Active development

The project is maintained by its original author, Graham Dumpleton. The 6.x release line is the current focus of development. Recent and ongoing themes include:

  • Surfacing and documenting mod_wsgi’s internal metrics, including a monitoring UI and paths for integration with external monitoring systems.

  • Opt-in support for Python’s evolving concurrency models: the per-interpreter GIL (PEP 684) and free-threaded Python (PEP 703).

  • Reliability improvements, such as the v6 request-timeout machinery.

  • Worked examples of using AI tooling to help tune Apache and mod_wsgi configuration for a particular workload.

Version support

  • 6.x — current development line. New features and fixes go here.

  • 5.x — stable. Once 6.x has stabilised, 5.x will receive backports of essential fixes only; new features will not be backported.

  • Older versions (4.x and earlier) — no longer maintained. Linux distributions sometimes ship older versions of mod_wsgi as part of long-term-support releases; those older versions are not supported by this project even when shipped by an LTS distribution.

Python and Apache support

The current release requires Python 3.10 or later and Apache 2.4.

Earlier mod_wsgi releases held compatibility with end-of-life Python versions for a long time, largely because the code base was not seeing active updates. With 6.x, support for end-of-life Python versions is dropped more proactively, in line with upstream Python’s own support timeline.

Windows support

mod_wsgi has historically built and run on Windows, but Windows is not a platform that the project’s author actively uses or tests on. In earlier release lines, Windows confirmation amounted to verifying that pip install mod_wsgi produced a working build; some features were known not to work on Windows, including mod_wsgi-express start-server.

With the substantial changes in 6.x, it is currently unknown whether mod_wsgi still builds and runs cleanly on Windows. Continued Windows support will depend on users running mod_wsgi on Windows reporting issues, and helping to investigate them, via the GitHub issue tracker.

The historical mod_wsgi mailing list still exists as a read-only archive of past discussions but is no longer active and should not be used for new questions.
