StackHawk — Developer & Integration Docs
StackHawk is built to slot into AI agent-driven development pipelines with minimal friction. Here's what developers need to know:
Supported AI Coding Agent Integrations:
- Claude Code
- Cursor
- GitHub Copilot
- Codex
- Antigravity
Scanning approach: StackHawk performs runtime DAST — it scans a live, running instance of your application. This means your app must be running (locally, in a container, or in a CI environment) for a scan to execute. This approach eliminates false positives inherent to SAST/SCA tools by only reporting vulnerabilities that are actually reachable and exploitable at runtime.
Agent loop integration: StackHawk is designed to operate within the AI agent's find → fix → verify loop:
- Agent triggers a StackHawk scan against the running app.
- StackHawk returns exploitable vulnerability findings via its API.
- The agent applies a fix.
- StackHawk re-scans to verify the fix before the PR is opened.
API: An API is available for programmatic scan management, result ingestion, and pipeline automation.
CI/CD: StackHawk produces a clean signal and per-commit attestation, suitable for use as a security gate in CI pipelines.
Open source: Core components are open source and available on GitHub (16 stars).
Plan limits relevant to developers:
- Wingman: 50 scans/user/month, unlimited apps.
- Scale: Unlimited agentic scans, unlimited apps (custom pricing).
