EXAMPLE · NOT A REAL ENDORSEMENT“The kind of security app I’d want to understand, not just install.”
EXAMPLE · NOT A REAL ENDORSEMENT“Clear tools, readable code, and room to contribute. That’s a promising start.”

Yes. The source code is MIT licensed. There are no paid editions, subscriptions, upgrade prompts, or limits created to sell you a higher tier.
The application has no telemetry, analytics, or sample uploads. Signature updates contact only the feed you explicitly configure. This static website includes no analytics or tracking scripts.
This is an early source preview with example signatures, not independently certified endpoint protection. Keep your existing protection while testing FerXium. See the documentation for exact coverage.
Created and modified files in selected folders, plus sampled running executable files. Native watchers observe changes after they occur; this release does not block file access or execution.
The source targets all three platforms. CI builds check each platform. Signed public installers will appear on the download page when release validation is complete.
Test harmless fixtures, improve signatures, review the security model, polish accessibility, or help with platform adapters. Start with the contribution guide.
