KavachOS vs Keycloak

KavachOS vs Keycloak

Keycloak is battle-tested enterprise IAM, but it is a Java monolith that takes real effort to deploy, tune, and maintain. KavachOS covers enterprise SSO and adds agent identity, MCP OAuth 2.1, and an edge-native runtime.

Why switch

Keycloak is heavy to run

A production Keycloak deployment typically needs 512 MB to 1 GB of RAM at minimum, a Postgres or MySQL database, and regular JVM tuning. KavachOS Cloud is fully managed. Self-hosted KavachOS runs on Cloudflare Workers or a single Node.js process with SQLite.

No agent identity or MCP support

Keycloak's service accounts and client credentials cover M2M patterns from 2015. There is no concept of AI agent tokens, delegation chains, or MCP OAuth 2.1. KavachOS ships these as first-class primitives.

Open source, but developer experience is a decade behind

Keycloak's admin UI and configuration model were designed for enterprise IT teams, not developers. Realm exports, protocol mappers, and flow configurations have a steep learning curve. KavachOS ships with a clean dashboard and a TypeScript-first SDK.

Feature comparison

10 features Keycloak doesn't have

FeatureKavachOSKeycloak
AI agent identity

Keycloak service accounts are not agent-identity primitives

MCP OAuth 2.1

KavachOS is spec-compliant; Keycloak has no MCP support

Agent delegation chains
Agent permission scoping
Agent audit log
Self-hosting

Keycloak is self-host only — no SaaS option

Open source (MIT)

Keycloak is Apache 2.0, not MIT

Social / OAuth providers (27+)

Keycloak supports social providers via identity brokering

Passkeys / WebAuthn

Keycloak added WebAuthn support in v9

Magic link

Keycloak has no native magic link; requires a custom authenticator SPI

Multi-factor authentication
Enterprise SSO (SAML, OIDC)

Keycloak's strongest area — SAML, OIDC, LDAP, Kerberos

SCIM provisioning

SCIM requires a third-party Keycloak extension

Organizations / multi-tenancy

Keycloak uses separate realms for tenancy — complex to manage at scale

Machine-to-machine tokens

Keycloak service accounts support client credentials grant

Custom domains

Keycloak supports custom domains via reverse proxy

Custom email templates
Brute force protection
Breach password detection
Free tier

Keycloak is free to self-host; no managed cloud tier

Cloudflare Workers runtime

Keycloak requires a JVM — not edge-compatible

Keycloak

Keycloak itself is free to download and run. You pay for the infrastructure it runs on — typically a VM or container cluster with a Postgres database. Red Hat offers a supported enterprise distribution (RHBK) under a subscription. There is no hosted SaaS option from the Keycloak project.

Migration

Switch in an afternoon

1

Export your Keycloak realm as JSON using the Keycloak admin CLI (`kc.sh export --realm myrealm`). KavachOS can import users from this format, mapping Keycloak's user representation to KavachOS identities.

2

Re-create your SAML and OIDC enterprise connections in the KavachOS dashboard. KavachOS uses the same redirect URI patterns, so existing IdP configurations need only minor endpoint URL updates.

3

Replace Keycloak's OIDC token verification middleware in your services with the KavachOS token verify function. Both issue standard JWTs, so the verification logic changes are minimal.

4

Migrate client applications by updating the discovery endpoint URL from your Keycloak realm URL to your KavachOS project domain. Most OIDC libraries auto-configure from the discovery document.

5

Test your SSO flows, social logins, and MFA in staging. Once verified, update your DNS and decommission the Keycloak instance — no forced user re-authentication required for social and SSO users.

FAQ

Common questions

Keycloak is free. Why would I pay for KavachOS Cloud?+
Keycloak's software is free, but running it is not. A production deployment needs a JVM, a database, monitoring, regular upgrades, and someone who knows Keycloak's configuration model. KavachOS Cloud eliminates that operational overhead. If you prefer self-hosting, the MIT license makes KavachOS free too — and it runs without a JVM.
Does KavachOS support SAML and LDAP like Keycloak?+
KavachOS supports SAML and OIDC-based enterprise SSO on the Growth plan and above. LDAP directory sync is on the roadmap. If you need LDAP today, Keycloak remains the stronger choice for that specific use case.
How does multi-tenancy compare?+
Keycloak uses separate realms per tenant, which works but becomes difficult to manage once you have dozens of tenants — each realm has its own configuration, upgrade path, and resource footprint. KavachOS has a native organizations primitive that handles multi-tenancy within a single deployment.
Keycloak has been around since 2013. How mature is KavachOS?+
Keycloak's maturity is real — it covers a huge range of enterprise identity scenarios. KavachOS is newer and focused on a narrower, more modern problem set: TypeScript-first apps, edge runtimes, and AI agent auth. If your primary need is enterprise LDAP federation with complex authentication flows, Keycloak is still worth evaluating alongside KavachOS.
Can I run KavachOS on the same infrastructure as Keycloak?+
The self-hosted version of KavachOS runs on Node.js, Deno, Bun, or Cloudflare Workers. It does not need a JVM. You can run both side-by-side during migration, then decomission Keycloak once you've validated everything.
What about Keycloak's custom authentication flows (SPI)?+
Keycloak's SPI framework lets you write Java plugins for custom auth logic. KavachOS uses TypeScript middleware and hooks instead. If you have heavily customized Keycloak flows, budget time to rewrite those in TypeScript — the logic is usually straightforward, but it is not a one-click migration.
