Find and prevent zero-days and other critical bugs, with customizable alerts and automated code review

by Semmle

Unparalleled security analysis

LGTM’s security analysis is powered by findings from our dedicated team of security researchers, and by contributions from security teams at a number of top tech companies.

Automated code review

Prevent bugs from ever appearing in your project by automatically catching them in the review process before they get merged.

Free for Open Source

LGTM is completely free for open source projects. We integrate with GitHub and BitBucket, and can analyze projects written in Java, Python, JavaScript, TypeScript, C and C++.

Deep semantic code search

All of our analyses are open source, and written as queries in Semmle QL, our deep semantic code search engine. You can even write your own queries to find and prevent mistakes or issues that matter to you.
