YARA tools that run in your browser

All tools use YARA-X 1.20.0, compiled to WebAssembly and run in a Web Worker. Files and rules stay on your device.

• Online YARA scanner

  Drop files or ZIPs and scan them with library rules or your own. Offsets, hex preview, CSV/JSON export.

• YARA rule editor & online tester

  Write a rule with live YARA-X errors, test it against a sample, or build one from a form.

• YARA rule linter & formatter

  Spot slow patterns and missing guards, then format the rule consistently.

Privacy: files are read with the File API and scanned in memory. No upload, no server-side processing, no analytics on file contents.
