HoundDog.ai
HoundDog.ai scans source code to map sensitive data flows and give AI coding agents cross-repo API context. Its Privacy Code Scanner traces PII, PHI, secrets, and third-party or AI SDK usage into logs, storage, and external sinks, then exports GDPR data maps and RoPA suggestions backed by code evidence. The Dataflow Context Engine builds a service catalog of APIs, fields, and downstream consumers for MCP-connected agents.
Unlike reactive DLP tools that redact data after it lands in logs, HoundDog.ai flags risky log statements and LLM prompts at scan time in the IDE or pull request. The homepage cites a Replit deployment protecting 45M users with 10k daily scans, and an internal demo where MCP context cut agent runtime from 9m 57s to 1m 23s.
HoundDog.ai targets AppSec engineers, privacy teams, and platform engineers at enterprises that need GDPR, HIPAA, or EU AI Act evidence tied to real code changes. Free CLI and GitHub scanner tiers exist, while enterprise plans add org-wide CI scanning, PIA workflows, and cloud or on-prem hosting.
Privacy Code Scanner is free on GitHub with local Markdown reports and IDE plugins for VS Code, Cursor, and IntelliJ
Enterprise Privacy Code Scanner costs $200 per developer per year for org-wide CI coverage
Tracks 100+ sensitive data types across code paths into logs, storage, APIs, and LLM prompts
Detects 1,000+ third-party and AI integrations, including shadow AI, directly from source code
Dataflow Context Engine MCP demo ran 7× faster and 6× cheaper than baseline agent grep workflows
Supports cloud SaaS or on-premises deployment with SSO, RBAC, and audit logs
Flags PII and secrets in log statements before code ships instead of scrubbing logs later
Free GitHub scanner lets developers test dataflow reports without a sales call
MCP context can cut AI agent time and token cost on cross-service changes
Covers GDPR, HIPAA, CCPA, and EU AI Act workflows from one code graph
Enterprise tier supports on-premises deployment for regulated environments
Full RoPA and PIA automation requires the paid enterprise privacy plan
Centralized context engine needs cloud or on-prem setup beyond the local free tier
Value depends on having repositories connected to CI or local checkouts
Demo benchmarks come from HoundDog.ai's own MCP comparison, not third-party tests
What does HoundDog.ai do?
HoundDog.ai offers a Privacy Code Scanner for GDPR data mapping and RoPA evidence plus a Dataflow Context Engine that maps APIs and fields across repos for AI coding agents. Both products analyze deterministic dataflows from your codebase.
Is HoundDog.ai free?
Yes. HoundDog.ai lists a free forever Privacy Code Scanner on GitHub with CLI access, IDE plugins, and local Markdown reports. Enterprise privacy scanning starts at $200 per developer per year for continuous org-wide coverage.
How does HoundDog.ai help with GDPR?
HoundDog.ai generates GDPR sensitive data maps, RoPA suggestions, and privacy impact assessment evidence from code scans. Privacy teams review suggested subprocessors and data categories before approving updates.
Does HoundDog.ai integrate with AI coding agents?
Yes. HoundDog.ai ships MCP servers, Skills, and a Dataflow Context Engine that returns structured service catalogs so agents avoid expensive repo-wide grep workflows when editing APIs.
What languages does HoundDog.ai support?
HoundDog.ai's free scanner detects sensitive data leaks across all supported languages in checked-out repositories. Enterprise deployments add CI integrations for GitHub, GitLab, and Bitbucket.
Who uses HoundDog.ai?
