Databunker

Databunker is a self‑hosted, Go‑based service that stores personal data as encrypted records and exposes them through a NoSQL‑like REST API. When a client submits a sensitive field, the system replaces it with a UUID token, keeping the original value only in an encrypted vault. Queries use hash‑based indexes, and bulk retrieval is disabled by default, while built‑in protections block SQL and GraphQL injection attacks.

The tool targets developers who need to protect PII, PHI, KYC or PCI information while remaining compliant with GDPR, CCPA, HIPAA and similar regulations. It can be deployed on‑premises or in any cloud environment via Docker, Kubernetes or OpenShift, and it provides an audit trail and consent management out of the box. An MIT‑licensed open‑source core makes it free for commercial use without subscription fees.

Key distinctions include token‑based data referencing, API‑level encryption that goes beyond disk‑level encryption, and a design that eliminates plaintext storage and mitigates injection‑based data leaks. The system can be up and running in minutes, offering a lightweight alternative to custom encryption implementations.
