Continuous security analysis

LGTM is a code analysis platform for identifying vulnerabilities and preventing them from reaching production.

LGTM automatically runs 1600+ standard analyses contributed by researchers from the Semmle Security Research Team and our customer community, including Microsoft, Google, Uber and Mozilla.

Quickly refine and run custom QL queries to find variants of known issues and prevent them from being re-introduced into your codebase.

DeepSource is the fastest and the most reliable way to run static analysis on your code. Our 13+ analyzers help you prevent thousands of security and bug risks, anti-patterns, and other defects before your code is merged.
