Insider is a free static application security testing tool. Semgrep Code is a commercial static application security testing tool by Semgrep. Compare features, ratings, integrations, and community reviews side by side to find the best static application security testing fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Development teams in fast-moving startups and mid-market companies should use Insider if they need SAST integrated directly into CI/CD without licensing friction. It scans six programming languages for OWASP Top 10 issues at zero cost, and the 550 GitHub stars signal real adoption among teams that value transparency and open-source tooling. Skip this if you need commercial support, a managed SaaS console, or detection capabilities beyond known vulnerability patterns; Insider is a CLI-first tool for developers who prefer running their own security scanning rather than outsourcing it to a vendor platform.
Development teams shipping code across 30+ languages need Semgrep Code because it catches vulnerabilities in pull requests before merge, not in staging; the AI-powered triage cuts false positives by filtering GPT-4 findings through 900+ high-confidence rules, so developers actually fix real issues instead of ignoring alerts. Scans complete in under five minutes with native GitHub and GitLab integration, meaning security checks won't become a bottleneck in your CI/CD. Skip this if your primary concern is runtime or infrastructure risk; Semgrep Code prioritizes the ID.RA and PR.PS phases where developers can still act, not post-deployment detection.
Insider is an open-source CLI tool that performs static source code analysis to detect OWASP Top 10 vulnerabilities across multiple programming languages including Java, Kotlin, Swift, .NET, C#, and JavaScript.
