gokart
A static analysis tool for Go that finds vulnerabilities using SSA form and source-to-sink tracing to reduce false positives.
What is gokart?
GoKart is a static analysis tool specifically for Go code that identifies security vulnerabilities like SQL injection by tracing the flow of data from sources to sinks. It uses Single Static Assignment (SSA) form to analyze variable assignments, which helps distinguish between actual vulnerabilities and false positives. The tool aims to provide accurate, actionable security findings to improve code safety.
Go developers, security engineers, and DevOps teams who need to integrate security scanning into their development workflow, especially those frustrated by high false positive rates in other static analysis tools.
Developers choose GoKart for its significantly lower false positive rate due to advanced source-to-sink tracing and SSA-based analysis, making security feedback more trustworthy and actionable. Its extensibility, support for remote repositories, and CI/CD integration options provide flexibility for diverse development environments.
Overview
A static analysis tool for securing Go code
Use Cases
Best For
- Integrating security scanning into Go CI/CD pipelines with SARIF output
- Reducing false positives in vulnerability detection for Go applications
- Scanning private or public Git repositories directly without manual cloning
- Extending static analysis with custom vulnerability sinks via YAML configuration
- Running security checks in Docker containers for consistent environments
- Educating developers on secure coding practices by tracing data flow in Go code
Not Ideal For
- Projects with polyglot codebases requiring security scanning across multiple languages
- Teams needing real-time, IDE-integrated security analysis during development
- Organizations prioritizing maximum vulnerability coverage over false positive reduction
- Environments where minimal setup and zero configuration are critical for quick adoption
Pros & Cons
Pros
Leverages SSA-based source-to-sink tracing to minimize false positives, as shown in the go-test-bench example where it distinguishes constant variables from real threats.
Supports custom vulnerability sinks via YAML configuration, allowing users to define new analyzers, demonstrated with the Test Sink example in the README.
Outputs findings in SARIF format and offers Docker support, enabling seamless pipeline integration and consistent execution environments.
Can scan public or private Git repositories directly with SSH key authentication, eliminating manual cloning, as detailed in the Docker and usage sections.
Cons
Exclusively analyzes Go code, making it ineffective for projects with mixed programming languages without additional tools.
Defining custom analyzers requires understanding YAML syntax and Go's SSA form, which can be steep for users without static analysis expertise.
Heavy promotion of Praetorian's commercial Chariot platform in the README suggests potential feature limitations or upsells in the free version.
Deep SSA analysis and tracing may slow down scans on large codebases, a common issue not explicitly addressed but implied by the intensive methodology.
