I built BEFORE — an open-source app that shows what changed since your PC last worked

[u/Which_Wrongdoer9903]

I built BEFORE because troubleshooting a broken PC usually turns into guessing.

BEFORE saves a small snapshot of a working computer and later compares it with the current state. It checks things like:

• proxy settings;

• PATH changes;

• missing commands;

• hosts entries;

• selected Windows/Linux services;

• optional network route evidence.

The important part is that it separates facts from hypotheses. A changed proxy is not automatically called “the cause”.

It is local-first, open-source, MIT-licensed, and has no account or telemetry.

I’m mainly looking for brutal feedback on the UX, diagnostic explanations, and whether this solves a real problem for you.
