No. The package is abandoned (last commit 2020-06-05), carries a copyleft license that may conflict with your project, has high install friction, and offers no documented compatibility with modern Python or Django. The author warned against production use at release. Use a maintained alternative instead.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Django (not listed as explicit dependency); Python version compatibility unknown; source-only distribution requires build tools.
- High install friction due to source-only distribution.

What it is and what it does
Jason is a minimal helper library for Django views that serialize data to JSON responses. It was released on 2014-06-24 and has not been maintained since; the author explicitly noted the API was still in flux and not recommended for production at the time of release.
The package provides convenience functions to reduce boilerplate when returning JSON from Django view handlers. With no runtime dependencies declared and a source-only distribution, installation requires a working build environment. The project shows no activity since 2020-06-05 and there is no indication of support for modern Python or Django versions.
Use it for
- Legacy Django projects that already depend on jason and need to remain on old codebases.
- Educational reference for understanding early Django JSON serialization patterns.
- Retrofitting minimal JSON endpoints in very old Django applications where upgrading is not feasible.
