KavachOS vs Auth0 — Agent-first auth at a fraction of the cost

Name: kavachOS
Author: kavachOS

Why switch

Agent identity, not an afterthought

Auth0 has no concept of AI agent tokens, delegation chains, or MCP OAuth 2.1. KavachOS ships these as first-class primitives — agents get their own identity, scoped permissions, and an audit trail.

Self-host or use the cloud

Auth0 is cloud-only. KavachOS is MIT-licensed and runs on Node.js, Deno, Bun, and Cloudflare Workers. Keep data on your infrastructure when you need to.

Predictable pricing that scales

Auth0 charges per MAU and gates enterprise features behind expensive plans. KavachOS Cloud starts free up to 1,000 MAU, with flat tiers that don't punish growth.

Auth0

Auth0 charges per Monthly Active User across three tiers. M2M tokens, Organizations, and enterprise features are billed separately. At 10,000 MAU you are already paying $240+/month.

Migration

Switch in an afternoon

Export your users from Auth0 using the Management API bulk export endpoint — KavachOS accepts the same JSON format with a one-time import command.

Replace the Auth0 SDK with `kavachos` via npm. The session and token APIs follow the same OAuth 2.0 conventions, so most route handlers need minimal changes.

Update your callback URLs and environment variables — swap `AUTH0_DOMAIN`, `AUTH0_CLIENT_ID`, and `AUTH0_CLIENT_SECRET` for their KavachOS equivalents.

Re-create your social connections and enterprise SSO connections in the KavachOS dashboard. The same redirect URIs are supported.

Run the migration checklist in the KavachOS CLI (`kavachos migrate verify`) to catch any gaps before switching DNS.

FAQ

Common questions

Can I import my existing Auth0 users?+

Yes. KavachOS has a first-class import command that accepts the JSON format Auth0 exports via its bulk user export endpoint. Passwords hashed with bcrypt migrate without requiring users to reset them.

Does KavachOS support all the social providers Auth0 does?+

KavachOS ships with 27+ OAuth providers including Google, GitHub, Microsoft, Apple, Facebook, Twitter/X, LinkedIn, and more. If you need a provider we don't have, you can configure any OAuth 2.0-compliant provider manually.

Is enterprise SSO included in all plans?+

SAML and OIDC-based enterprise SSO are included from the Growth plan upward. Auth0 requires the Professional or Enterprise plan for this feature.

How does KavachOS handle M2M tokens compared to Auth0?+

KavachOS includes machine-to-machine tokens on all paid plans at no extra charge. Auth0 bills M2M token usage separately, which can become very expensive at scale for agent-heavy workloads.

What is agent identity and why does it matter?+

Agent identity gives AI agents their own cryptographic identity — separate from the human user who authorized them. This means you can see exactly which agent took which action, revoke individual agent tokens without affecting the user, and enforce scoped permissions per agent. Auth0 has no equivalent concept.

Can I keep using Auth0 for humans and add KavachOS just for agents?+

Yes, but you would be running two auth systems. Most teams find it simpler to consolidate on KavachOS so the delegation chain between humans and agents is visible in one place.
