Shadow DB is the open-source, self-hosted data sovereignty engine. It mirrors every record from Notion, Airtable, Linear, and more into a structured Postgres database you control. Tamper-evident. Encrypted. No vendor lock-in.
Notion doubles their pricing. Airtable changes their terms. A platform bans your account. Suddenly your entire business is trapped inside a proprietary data store you can't access.
We're a cybersecurity firm. We don't trust third parties with our data, and neither should you. Shadow DB runs entirely on your infrastructure. Your records are AES-256 encrypted at rest, SHA-256 hashed for tamper detection, and always one click away from migration.
Add your SaaS API keys. Shadow DB encrypts them with AES-256-GCM before they ever touch your database.
POST /api/connections
BullMQ workers pull your data on schedule — paginated, normalized, and upserted into your own Postgres instance. Every record gets a SHA-256 hash.
Query your shadow database directly. Detect tampering via hash mismatches. Migrate to any platform instantly if your vendor goes sideways.
