Semgrep is an AppSec platform with a widely used open-source engine for readable code rules plus commercial SAST, supply-chain and secrets workflows. Current product positioning emphasizes AI-assisted detection, triage and remediation, CI/pull-request integration and managed governance for security teams.

We have a review for this tool

A detailed review by the aicoolies team — click to read

Semgrep helps teams find insecure code patterns, dependency risk and leaked secrets close to developer workflows. Its readable rule model remains the core advantage: AppSec and platform teams can encode policies that look like code, run them locally or in CI, and tune findings without treating static analysis as a black box.

Current Semgrep positioning is broader than an older static-analysis-only description. The product surface includes Semgrep Code for SAST, Semgrep Supply Chain for dependency risk, Semgrep Secrets, Guardian, AI-assisted triage and remediation, managed scanning and governance for teams that need platform-level AppSec workflows.

The open-source engine should be described with license nuance rather than old star-count or MIT shorthand. GitHub currently reports semgrep/semgrep with LGPL-2.1 metadata and more than fifteen thousand stars, while the commercial platform adds hosted workflows, support and enterprise controls. Buyers should test rule quality, CI performance and finding noise on their own repositories.

Pricing

Free tier includes AI credits with limits up to 10 repos and 10 contributors; Teams modules are Code $30/contributor/mo, Supply Chain $30/contributor/mo and Secrets $15/contributor/mo; Enterprise custom.

Platforms

CLI, Semgrep AppSec Platform, GitHub/GitLab workflows, CI/CD, pull requests, SAST, SCA, secrets scanning, Guardian, AI-assisted triage and remediation.

Semgrep vs Snyk: Custom Rules or Full-Platform Developer Security?

Semgrep wins for code-first AppSec teams that want custom rules, CI guardrails, and source-level security control. Snyk is the better fit when one enterprise platform must cover SCA, SAST, containers, IaC, remediation, and governance.

Semgrep vs SonarCloud — AST-Level Rule Authoring vs Hosted Quality Gate Breadth

Semgrep and SonarCloud both catch security and quality issues in source code, but they approach the problem from opposite ends. Semgrep is a rule-based static analysis engine built for security engineers who want AST-level pattern precision and a community rule registry to extend. SonarCloud is a hosted code quality platform that bundles Quality Gates, PR decoration, technical debt tracking, and broad language coverage into one workflow. Picking between them depends on whether your primary concern is AppSec rule precision or developer-facing quality feedback at organizational scale.
