Your AI writes code. We catch the bugs it leaves behind.
Cursor and Copilot hallucinate APIs, leak secrets, and skip auth checks. CodeSheriff catches all of it on every PR. The only scanner built specifically for AI-generated code.
stripe.charges.createInstant() does not exist in stripe-node v12.x. This is a hallucinated API call that will throw at runtime.

Catches what AI misses -- every single PR
AI coding assistants are fast, but they hallucinate APIs, leak credentials, and skip authorization checks. CodeSheriff runs on every PR and posts inline comments so your team catches issues before merge -- not after incident.
Hallucinated APIs
Methods that don't exist in the SDK version you're using
Hardcoded secrets
API keys, passwords, and tokens committed to your repo
Auth & logic bugs
IDOR vulnerabilities and missing authorization checks
Every layer of defense, AI-aware
Semgrep for static analysis, TruffleHog for secrets, and Claude AI detectors for the hallucinations and logic bugs traditional scanners can't see.
AI Hallucination Detection
Claude-powered analysis identifies API calls, imports, and patterns that don't exist in the libraries you're actually using -- before they blow up in production.
Secrets & Credentials
TruffleHog integration catches hardcoded API keys, database passwords, JWT secrets, and OAuth tokens across 700+ secret types.
Auth Flow & IDOR Bugs
Detects missing authorization checks, insecure direct object references, and authentication bypass patterns that LLMs commonly introduce.
Risk Score 0-100
Every repository gets a live risk score factoring in finding severity, recency, and code coverage. Watch your score drop as you fix issues.
Inline PR Comments
Findings appear as inline GitHub or GitLab code review comments with line-level context, suggested fixes, and severity ratings.
GitHub Check Runs
Block merges on critical findings with native GitHub Check Run integration. Set custom thresholds per branch or environment.
SARIF Export
Export findings in SARIF format for integration with GitHub Advanced Security, Azure DevOps, and any security dashboard that speaks SARIF.
GitHub & GitLab
Full support for GitHub PRs and GitLab MRs out of the box. Inline comments, check runs, and merge request feedback -- wherever your team works.
Slack & Webhooks
Get instant Slack alerts when a critical finding is detected. Configurable webhooks send structured JSON to any downstream system.
A scanner that gets smarter every week
Static rule engines never improve. CodeSheriff\u0027s Autotune engine learns from your team\u0027s feedback to reduce false positives and catch more real issues -- automatically, with zero configuration.
Scan detects a finding
CodeSheriff flags a potential issue in your PR -- a hallucinated API call, an auth bypass, or a hardcoded secret.
Developer gives feedback
Your team marks the finding as a true positive or false positive with a single click in the PR comment.
Autotune updates the model
CodeSheriff's detection engine learns from every decision. True positives reinforce the pattern; false positives suppress it.
Accuracy improves over time
Each week, your scanner gets more precise. After 30 days, teams see 40-60% fewer false positives -- automatically.
- Static rules that never change
- Same false positive rate forever
- Manual rule tuning required
- One-size-fits-all detection
- Detection improves with every PR
- 40-60% fewer false positives after 30 days
- Zero-config -- learns from team feedback
- Adapts to your codebase and patterns
Three steps. Zero friction.
No CI changes. No YAML files. No infrastructure to manage. Just run the command and start catching bugs.
Install
One command. No CI pipeline changes, no infrastructure, no config files.

Running GitLab? Most AI reviewers cannot help you.
Cubic, Qodo, and most AI code review tools are GitHub-only. CodeSheriff supports GitLab MRs and push events out of the box. If your team runs GitLab, we are the only AI code safety scanner that works where you do.
Average reduction in false positives after 30 days of Autotune, based on teams with 10+ PRs per week. Your scanner adapts to your codebase -- no manual tuning required.
Trusted by security-conscious teams
From Series A startups to enterprise engineering orgs.
“We moved to Cursor + Copilot last quarter and our PR review load tripled. CodeSheriff cut our security-related review time by ~70%. It catches the dumb stuff so we can focus on architecture.”
“Found a hallucinated Stripe method that had passed 3 code reviews. Would've shipped to prod and silently started failing charges. CodeSheriff caught it in 12 seconds.”
“The Autotune engine is the killer feature. After 3 weeks of our team marking findings, false positives dropped by half. No other scanner does that . Snyk and Semgrep just gave us the same noise forever.”
