Semmle
Semmle
English code analysis platform
Semmle Inc is a code-analysis platform; Semmle was acquired by GitHub (itself owned by Microsoft) on 18 September 2019 for an undisclosed amount.[2] Semmle's LGTM technology automates code review, tracks developer contributions, and flags software security issues.[2] The LGTM platform leverages the CodeQL query engine (formerly QL)[3] to perform semantic analysis on software code bases. GitHub aims to integrate Semmle technology to provide continuous vulnerability detection services.[4] In November 2019, use of CodeQL was made free for research and open source.[5] CodeQL either shares a direct pedigree with .QL (dot-que-ell), which derives from the Datalog family tree, or is an evolution of similar technology.[clarification needed]
SemmleCode is an object-oriented query language for deductive databases developed by Semmle. It is distinguished within this class by its support for recursive query.
