Some New Projects Are Using Harper

I re­cently did some snoop­ing (through Dependabot) on what open source pro­jects have been us­ing Harper. Since I last checked, there are some new ones. I won­der if the re­cent ad­di­tions have any­thing to do with Harper go­ing 1.0.

Someone also wrote a book us­ing Harper.

This post is now out-of-date. There are even more pro­jects us­ing Harper to­day (as of 6.11.2026). The canon­i­cal list ex­ists in Harper’s Documentation

First of all, I have to say Harper is a very great project. Keep up the good work 💪. I am curious whether Harper supports Harper or plans to support python

Thank you for the kinds words! Right now, it is not on the roadmap. One of our main contributors did some tinkering a while back, which you're welcome to take a look at. If you'd like that work to turn into an official library, please file an issue. https://github.com/hippietrail/harper-py
