Unyform vs Semgrep
Semgrep is the developer’s favorite static analysis tool — lightweight, fast, and built for custom rules. With 2,500+ community rules and support for 30+ languages, it is a staple of modern security toolchains. But Semgrep and Unyform solve fundamentally different problems at different stages of the development lifecycle.
Semgrep catches patterns in committed code. Unyform prevents them at the point of generation. They are complementary, but they solve different problems.
What Semgrep Does
- Fast, lightweight AST-based static analysis with custom rule authoring
- 2,500+ community rule registry covering security, correctness, and best practices
- CI/CD integration — scans code in pull requests and pipelines
- Developer-friendly — fast feedback, low false positive rates, easy rule syntax
- 30+ language support with consistent pattern matching across languages
What Semgrep Does Not Do
- Post-commit only — Semgrep scans code after it is written, not during generation
- No AI awareness — treats all code the same regardless of whether it was AI-generated
- No generation-time governance — cannot influence what AI coding tools produce
- No architectural enforcement — cannot enforce design patterns, conventions, or organizational standards
- No AI interaction audit trail — no record of AI-assisted development for compliance reporting
The Timing Gap
Semgrep runs in CI — after code has been generated, committed, and pushed. When it flags an issue in AI-generated code, the developer goes back to the AI tool, regenerates, commits again, and waits for Semgrep to run again. With AI tools generating thousands of lines per day, these review-reject-regenerate loops compound. Unyform eliminates the loop by governing code at the point of generation — before it ever reaches Semgrep’s scanners.
Comparison
| Dimension | Semgrep | Unyform |
|---|---|---|
| When it acts | After code is committed | At the point of generation |
| Approach | Reactive — scan and flag | Proactive — govern and align |
| AI awareness | None — treats all code the same | Built for AI-generated code |
| Organizational context | Custom rules only | Blueprint Graph — patterns, architecture, policies |
| Architectural governance | No | Yes — enforces patterns at generation |
| Rule ecosystem | 2,500+ community rules | Automatic policy enforcement from Blueprint Graph |
| Feedback loops | Flag → fix → rescan | None — code is correct the first time |
Complementary, Not Competitive
Semgrep and Unyform are complementary. Semgrep excels at catching patterns in committed code — custom rules for security, correctness, and best practices across 30+ languages. Unyform governs AI-generated code at the point of generation, preventing the majority of issues before they reach Semgrep’s scanners. Together, they create defense in depth: proactive governance at generation time, pattern-based scanning at commit time.
