KavachOS vs better-auth
Both are MIT TypeScript libraries with a broad OAuth provider list. The split is agent primitives: better-auth treats agents as OAuth clients; KavachOS makes them first-class entities with delegation, ephemeral sessions, trust scoring, and compliance exports.
KavachOS vs Hanko
Hanko is a passkey-first library with an AGPL backend. If passkeys are your entire auth story and you have no agent workloads, it’s worth a look. If you need any agent identity or RBAC, you’ll be building on top of it yourself.
KavachOS vs Casdoor
Casdoor is a deployed Go IAM service with LDAP, CAS, and RADIUS support. It targets employee SSO in Go shops. KavachOS is a library, not a service, and it’s built for agent-native TypeScript apps.
KavachOS vs paid options
Clerk and Auth0 are polished, fast to start, and expensive at scale. They’re also closed-source. This page covers the open-source vs. managed tradeoff without reproducing any pricing tables.
