Semgrep AI
AI-augmented static analysis (open source)
Overview
Semgrep is a fast, open-source SAST tool — its AI Assistant feature uses LLMs to triage findings, generate fixes, and craft custom rules from natural-language descriptions. Used by GitLab, Slack, Snowflake and many others. Free OSS tier; commercial Semgrep Cloud Platform.

Use cases
What you can produce with Semgrep AI
- Scan a codebase for OWASP Top 10 vulnerability patterns in CI and block pull requests that introduce new findings.
- Write a custom rule in readable YAML that flags your organisation's specific insecure code pattern, then enforce it across every repository.
- Use the AI Assistant to auto-triage findings, filtering likely false positives so developers only see actionable issues.
- Generate a working Semgrep rule from a natural-language description of the code pattern you want to catch.
- Detect hardcoded secrets and vulnerable open-source dependencies alongside first-party code issues in a single pipeline.
- Run the open-source engine locally from the command line for free, pre-commit or ad hoc, with thousands of community rules.
- Apply AI-generated autofix suggestions to remediate findings directly in the pull request.

Semgrep is one of the strongest developer-first application security platforms: fast pattern-based static analysis, secrets detection, supply-chain (SCA) scanning, and an AI layer (Semgrep Assistant) that triages findings and proposes fixes to cut false positives. The open-source engine and large community rule registry make it easy to adopt and customise, and CI/CD integration is excellent.
It suits engineering and AppSec teams that want low-noise scanning embedded in pull requests rather than a heavy enterprise scanner. The generous free/open-source tier is a major value point. Caveats: the AI features and org-wide policy management sit behind paid tiers, writing custom rules has a learning curve, and as English-only SaaS there is no SEA-specific support or data residency, though the self-hostable engine mitigates this. API and CLI tooling are first-rate.
What people say
Semgrep remains one of the most developer-liked SAST tools on the market, and the company behind it is healthy: it raised a $100 million Series D led by Menlo Ventures in February 2025, launched its 'Multimodal' AI-plus-rules analysis in March 2026, and was named one of the initial recipients of OpenAI's cybersecurity grant program. It stays a private, independent San Francisco company of around 260 people.
What users consistently praise is the core scanning experience: fast scans, comparatively low noise, and rules you can actually read and write. The pattern-matching rule syntax is Semgrep's signature — security engineers describe encoding an organisation-specific anti-pattern in an afternoon, something that is genuinely hard in most competing SAST tools. Reviewers on G2 and Gartner Peer Insights also call out easy CI and IDE integration and remediation guidance that developers do not resent. The AI Assistant's triage of findings and autofix suggestions get generally positive marks for cutting through backlog.
The recurring complaints: writing advanced rules (taint tracking, cross-function analysis) has a real learning curve; language support maturity is uneven, with newer languages lagging the polished Python/JavaScript/Java experience; and enterprise pricing and deployment feel less straightforward than the core product. The biggest community controversy was the December 2024 licensing change, which moved features out of open source and prompted more than ten competing vendors to fork the engine as Opengrep — a move that cost Semgrep goodwill among open-source purists, even as the commercial product kept improving.
Semgrep fits security teams that want customizable, low-noise static analysis embedded in developer workflows, and solo developers can still get far on the free tier. Teams ideologically committed to fully open-source tooling may prefer the Opengrep fork, accepting its less certain long-term stewardship.
