Seqra

Unit test your Java or Kotlin architecture.

A classpath and module path scanner for querying or visualizing class metadata or class relatedness.

The SpotBugs plugin for security audits of Java web applications and Android applications. (Also work with Kotlin, Groovy and Scala projects)

A static analysis tool written in scala for languages that run on JVM.

ast-grep is a powerful tool designed for managing code at scale using Abstract Syntax Trees (AST). Think of it as a hybrid of grep, eslint, and codemod, with the ability to search, lint, and rewrite code based on its structure rather than plain text. It supports multiple languages and is designed to be extensible, allowing you to register custom languages.

Checks your code and infra (various Git repositories supported, cloud stacks, CLI, Web Interface platform, integrationss available) for security and quality issues. Code Scanning/SAST/Linting using many tools/Scanners deduplicated with One Report (AI optional).

A language-agnostic linter that keeps code, documentation, and configuration in sync and enforces strict formatting and validation rules.

Corgea is an AI-powered SAST scanner that helps developers find and fix insecure code. It finds business logic flaws, broken authentication, API vulnerabilities, and more with little false positives. Additionally, it automatically writes security fixes for them to approve. Corgea integrates with GitHub, GitLab, Azure DevOps, IDEs and CLI. It is free to try it.

Multi-language Static Application Security Testing (SAST) platform that detects critical vulnerabilities, including hardcoded secrets, weak cryptography, backdoors, SQL injections, insecure configurations, etc.

Emerge is a source code and dependency visualizer that can be used to gather insights about source code structure, metrics, dependencies and complexity of software projects. After scanning the source code of a project it provides you an interactive web interface to explore and analyze your project by using graph structures.

Joern is a platform for analyzing source code, bytecode, and binary executables. It generates code property graphs (CPGs), a graph representation of code for cross-language code analysis. Code property graphs are stored in a custom graph database. This allows code to be mined using search queries formulated in a Scala-based domain-specific query language. Joern is developed with the goal of providing a useful tool for vulnerability discovery and research in static program analysis.

Mega-Linter can handle any type of project thanks to its 70+ embedded Linters, its advanced reporting, runnable on any CI system or locally, with assisted installation and configuration, able to apply formatting and fixes

OpenRewrite fixes common static analysis issues reported through Sonar and other tools using a Maven and Gradle plugin or the Moderne CLI.

Scan is a free open-source DevSecOps platform for detecting security issues in source code and dependencies. It supports a broad range of languages and CI/CD pipelines. Note: ShiftLeft rebranded to Qwiet AI in 2023, which was subsequently acquired by Harness in September 2025. This open-source project is no longer maintained.

Sigrid helps you to improve your software by measuring your system's code quality, and then compares the results against a benchmark of thousands of industry systems to give you concrete advice on areas where you can improve.

SonarQube for IDE (formerly SonarLint) is a free IDE extension available for IntelliJ, VS Code, Visual Studio, and Eclipse, to find and fix coding issues in real-time, flagging issues as you code, just like a spell-checker. More than a linter, it also delivers rich contextual guidance to help developers understand why there is an issue, assess the risk, and educate them on how to fix it.

Static Reviewer executes code checks according to the most relevant Secure Coding Standards, OWASP, CWE, CVE, CVSS, MISRA, CERT, for 40+ programming languages, using 1000+ built-in validation rules for Security, Deadcode & Best Practices Available a module for Software Composition Analysis (SCA) to find vulnerabilities in open source and third party libraries.

Tencent Cloud Code Analysis (TCA for short, code-named CodeDog inside the company early) is a comprehensive platform for code analysis and issue tracking. TCA consist of three components, server, web and client. It integrates of a number of self-developed tools, and also supports dynamic integration of code analysis tools in various programming languages.
