Semgrep vs StackHawk — AI Tool Comparison

TL;DR: Semgrep focuses on static analysis (SAST) that scans code without running it, offering broad coverage including secrets detection and open-source malware protection with an active community. StackHawk specializes in dynamic testing (DAST) that attacks your running application to find only exploitable vulnerabilities, making it particularly valuable for AI coding agents that can auto-fix issues before commit. Choose Semgrep for comprehensive pre-commit code scanning with open-source flexibility, or StackHawk if you need runtime verification that vulnerabilities are actually exploitable and want integration into automated coding workflows.
