After months of coding and testing, I finally finished programming a tool called CrashVault, a lightweight, local‑first crash/error vault with a simple CLI. Log errors, group them into issues, search, export/import, and keep a local history. I’m also implementing auto‑update, instancing, and more features!

Why I built it

I was looking for an open‑source tool to monitor errors—something unlike Datadog or Sentry—but couldn’t find anything that suited my needs. So I decided to build my own in Python.

NOTE: CrashVault uses a tool called Patchy (another tool I made) that currently only has support for Node.js and Python. I’m looking for help adding support for other languages.
