Hopdox is in active alpha testing. It accelerates and structures compliance assessment, but a qualified assessor remains accountable for every result. During alpha, do not process classified or sensitive material, or enter real identifiers, credentials, or PII.
Hopdox is built as a compiled Go application with an embedded React interface, REST API, live Server-Sent Events progress, assessment-local evidence indexing, checkpointed stage execution, and generated DOCX, PDF, and ZIP report outputs.
The alpha includes the application surfaces needed to run, inspect, pause, correct, and export an assessment, not just generate prose.
Hopdox is designed to minimise exposure of sensitive material, separate uploaded evidence from trusted guidance, constrain external calls, and keep a human decision-maker in control.
Alpha testing is limited to a small group of assessors and security leaders.
Available alpha test user slots have been exhausted. Please check back again.
