YARA Rule Tester Lite
Compile and test YARA rules locally against text or single files without sending data anywhere.
YARA Rule Tester Lite provides a browser-based workbench for validating rules, surfacing compile issues and checking quick matches against local content.
This Lite workflow is aimed at fast triage and single-target testing, not full feature parity with desktop YARA pipelines.
Rules input
Lite mode focuses on local compile-and-scan validation for single text or file targets.
No rules loaded
Paste YARA rules, choose a text or file target, then compile or scan locally in your browser.
Frequently Asked Questions
Can I run arbitrary YARA rules?
Yes. The Lite tester runs YARA rules in-browser using the integrated WASM engine; some advanced features may be limited by the WASM runtime.
Do files leave my browser?
No. Rule testing and any file matching runs locally; no data is sent to external servers.
How do I supply test data?
You can paste text or upload small files to test rules. For large datasets prefer local CLI tools.
