SAST Tool Comparison
SwarmFlow vs Semgrep
Semgrep is powerful for teams who write custom rules. SwarmFlow is zero-config — advanced AI does the security analysis without rules.
The core difference
Semgrep finds what your rules tell it to find. SwarmFlow finds what your code is actually doing wrong — including business logic vulnerabilities that no predefined rule would catch.
SwarmFlow
Zero configuration. advanced AI reads your code and finds vulnerabilities through semantic understanding — no rules to write or maintain.
- ✓Zero-config setup (2 minutes)
- ✓135 pre-built AI security agents
- ✓Context-aware — understands code intent
- ✓Detects business logic vulnerabilities
- ✓AI-generated fix suggestions
Semgrep
Highly customizable rule-based SAST. Community rules available but best results require writing and tuning your own patterns.
- ✓Powerful custom rule engine
- ✓Large community rule library
- ✓Excellent for consistent policy enforcement
- ✓Free OSS community edition
- ✓Good for known vulnerability patterns
