NodusDB is an authorization database you import, not a service you call. Write zanzibar-style permissions and check them through nested groups and folders in 14 µs, inside your own python process. Every write also lands in one signed log in your S3 bucket, which gives you replicas, an Iceberg table for SQL audit, time travel and GDPR erasure. Benchmarked in open against SpiceDB and OpenFGA. Free and open source.
