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 Token Tracker. Claude Code spend, tracked.
Local SQLite analytics for Claude Code: per-project, per-model, per-tool spend, 5-hour block forecasts, and budgets that fire desktop alerts. Cross-platform CLI plus a Linux GTK dashboard. Co-built with Statotech Systems.

Want us to build something?
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@ebstar.co.
