Things we build in the open.
The libraries we built while shipping the products, MIT-licensed, on PyPI and GitHub. We solve a real problem in our own work, then put the tool in the open for anyone who has it too.
Two libraries. Both MIT.
Updated 2026
hwpkit. Korean HWP, in Python.
Read, fill, and edit Korean HWP (Hancom Office) documents in Python, the binary format Korean government, universities, and most Korean enterprises run on. If your RAG pipeline can’t read HWP, it can’t index Korean enterprise data. pip install hwpkit.
Claude AI Usage Widget. Live usage gauge for Claude.
A system-tray gauge that shows how close you are to your Claude plan limits in real time, plus persistent local analytics: per-project, per-model, per-tool spend with budgets and forecasts. Cross-platform CLI and a Linux GTK dashboard.

These are the tools we built for ourselves. If you have a harder problem, tell us what you’re trying to build and who it’s for, or write to contact@ebenworks.co.
