Why KeepRails

KeepRails vs Semgrep

Semgrep is static analysis for your source code. KeepRails inventories endpoint-resident AI and records how that fleet state changes. Different object, different question.

Short answer

Semgrep reads your code. KeepRails reads the AI tooling that writes and runs it. Neither substitutes for the other, and most teams ship both.

vs mcp-scan vs Semgrep vs a manual audit Why not OpenTelemetry

Where Semgrep wins

Finding bugs and insecure patterns inside source codeA large, maintained rule ecosystem for application languagesCI gating on code-level findings

Where KeepRails wins

Inventorying the AI tooling installed on the machine, which SAST never seesMapping what it finds to inventory control referencesProducing an evidence artifact rather than a findings listKeeping prompts, code and configuration content on the device

Side by side

DimensionSemgrepKeepRails

What it analyzes Your application source code Endpoint-resident AI — apps, models, IDE AI, agents, MCP, and SDKs

Question answered Does my code contain a vulnerability or anti-pattern? Which endpoint-resident AI assets can I support with audit evidence?

Evidence coverage Rule findings, no compliance mapping Deterministic evidence mapped to five compliance frameworks

Primary artifact Source-code findings Evidence register, audit report, and CycloneDX AI-BOM

Data handling Depends on deployment (local CLI or cloud) Only sanitized tool-identity metadata leaves, on consent

Semgrep is excellent at what it does: fast, rule-based static analysis that finds bugs and insecure patterns in source code. KeepRails does not scan your code, and is not trying to replace a SAST tool.

The object is different. Semgrep reads your code; KeepRails reads your AI tooling configuration — which endpoint-resident AI assets were observed and what source supports each register entry. If you ship code, you want both: Semgrep on the code, KeepRails on the agent setup that writes and runs it. Comparing them is really about which problem you are solving right now.

Use both — that is the honest recommendation

The register becomes the input your assessor reviews, instead of the spreadsheet they distrust. Keep the human judgement; stop hand-collecting the inventory.
