About Walwarden
What is Walwarden?
Walwarden is a database backup and verification service that automates scheduled logical Postgres backups into customer-owned AWS S3 buckets with cryptographically signed evidence.
What Walwarden does
The platform connects to Supabase, Neon, or standard Postgres databases to perform scheduled logical backups directly into storage controlled by the user. Each backup produces an Ed25519-signed manifest recording artifact checksums and a hash-linked audit chain, allowing teams and AI agents to independently verify backups and audit histories offline with a matching public key.
Who Walwarden is for
Teams and operators running Supabase or Neon databases who want verifiable backups in their own S3 storage.
How Walwarden works
Users connect their Postgres database using read-only credentials, configure an IAM role for their AWS S3 bucket, and Walwarden executes scheduled backups, signs the evidence manifests, and enables operator-run restores via the CLI.
