Semgrep

Semgrep is an extensible, developer-friendly application security platform that scans source code to surface actionable security issues. It features static application security testing, software composition analysis, and secrets detection powered by an open-source engine under the LGPL alongside a paid platform for teams. Patterns are written in the syntax of the language being analyzed, allowing custom rules to be written easily.

• Semgrep Code for static application security testing to find and fix vulnerabilities in code
• Semgrep Supply Chain for fixing vulnerabilities in open source dependencies and blocking malware
• Semgrep Secrets for finding and fixing hardcoded secrets using semantic analysis, entropy analysis, and validation
• Semgrep Guardian for scanning and fixing AI-generated code as it is written
• Multimodal AI detection combining static analysis and AI reasoning for detection, triage, and remediation
• Semgrep AppSec Platform to automate, manage, and enforce security across an organization
• Agentic Workflows to build and deploy security pipelines combining static analysis with AI at scale
• A community registry and online interactive playground to write, find, and share rules

Pros

• Combines multiple security capabilities like SAST, SCA, and secrets scanning into a single platform built for developers
• Utilizes custom rules written in the syntax of the target programming language, making rules easier to write than traditional AST queries
• Employs reachability analysis in supply chain scanning to flag dependencies that actually matter and reduce irrelevant noise
• Applies semantic and entropy analysis along with validation to detect hardcoded secrets and block unsafe merges by default

Cons

• Specific pricing tiers and numeric costs are not published on the page text
• Requires evaluation against legacy tools like Checkmarx or Snyk to determine migration fit for specific enterprise environments

Semgrep fits development and security teams looking to unify SAST, SCA, and secrets scanning into a single workflow that lives where developers work. It is suited for fintech and SaaS and cloud environments seeking to secure code without sacrificing development velocity. It is a poor fit for organizations requiring completely offline or proprietary scanning engines without an open-source engine base or cloud platform integration.

The listing and website state a freemium model with a free tier and paid plans above it. The Free Edition is available at zero dollars per month per contributor for code and supply chain scanning, covering up to 10 repositories and 10 contributors with 60 AI credits included, using GitHub or GitLab authentication. The Teams tier starts at $30 per month per contributor for Code or Supply Chain detection, or $15 per month per contributor for Secrets detection, including 20 AI credits per developer per month, single sign-on, and one-click CI/CD deployment. The Enterprise tier features custom volume pricing by contacting sales, including 50 AI credits per developer per month, support for on-premise source code management and custom CI/CD integrations, dedicated support, and no limit on repositories or contributors.

Unlike traditional static analysis tools that rely on complex AST queries, Semgrep allows users to write custom rules using patterns written in the exact syntax of the language being analyzed. It integrates multimodal AI reasoning directly with rule-based analysis to uncover OWASP risks, business logic flaws, and IDORs that conventional scanners may miss.

The provided text does not explicitly list third-party integrations, software editors, or file formats by name beyond operating as an application security platform across modern development workflows.

Semgrep is worth trying for development and application security teams seeking an extensible platform that combines SAST, SCA, and secret detection with AI-assisted features. It offers a community edition under an LGPL open-source engine alongside a paid platform for teams. Buyers should check the pricing page directly for exact plan limitations since specific tier prices are not published in the text.
