What is FusionAuth?

FusionAuth's feed publishes version numbers; whether they carry news is a coin flip.

FusionAuth releases every four to eight weeks, but the changelog entries are inconsistent: three of the last six carry nothing but an upgrade-guide link, while the ones that do have notes describe substantial standards and security work. The last documented release, 1.67.0, added RFC 8707 resource scoping so tokens issued by OAuth endpoints can be bound to specific resources. Before it, two consecutive releases tightened API key requirements — 1.65.0 for installation-wide endpoints, 1.66.0 extending the same rule to webhooks it had missed.

What is Kinde?

Kinde went from connecting agents to itself to helping customers ship their own MCP servers

Kinde has been filling out the standard identity surface — passkeys via WebAuthn/FIDO2, IdP-initiated SAML SSO, WhatsApp delivery for verification codes, and organization-level invite controls — while building billing into the platform with self-serve plan management and the ability to cancel a customer. The newest release, Kinde Secure MCP, is a different kind of move: a beta that lets customers ship an MCP server for their own product so their users can reach it from Claude, Cursor and similar tools.

FusionAuth vs Kinde: editorial side-by-side

F2.5

FusionAuth's feed publishes version numbers; whether they carry news is a coin flip.

◆ Current state

FusionAuth releases every four to eight weeks, but the changelog entries are inconsistent: three of the last six carry nothing but an upgrade-guide link, while the ones that do have notes describe substantial standards and security work. The last documented release, 1.67.0, added RFC 8707 resource scoping so tokens issued by OAuth endpoints can be bound to specific resources. Before it, two consecutive releases tightened API key requirements — 1.65.0 for installation-wide endpoints, 1.66.0 extending the same rule to webhooks it had missed.

◆ Where it's heading

Where the notes are readable, the direction is standards conformance and closing security defaults that were too permissive, accepting breaking changes to do it. FusionAuth has been willing to make an enabled identity provider's linking strategy immutable and to require global API keys where tenant keys used to work — changes that break running deployments in exchange for a tighter default. What cannot be read from this feed is where the last two releases fit, because they shipped without notes.

◆ Prediction

The pattern of hardening endpoint-by-endpoint suggests further scope narrowing wherever tenant-level keys still reach installation-level effects. Any read on 1.68.0 and 1.69.0 would be guesswork — the entries carry no content.

Kinde went from connecting agents to itself to helping customers ship their own MCP servers

◆ Current state

Kinde has been filling out the standard identity surface — passkeys via WebAuthn/FIDO2, IdP-initiated SAML SSO, WhatsApp delivery for verification codes, and organization-level invite controls — while building billing into the platform with self-serve plan management and the ability to cancel a customer. The newest release, Kinde Secure MCP, is a different kind of move: a beta that lets customers ship an MCP server for their own product so their users can reach it from Claude, Cursor and similar tools.

◆ Where it's heading

January's Kinde MCP server let agents operate Kinde itself; Secure MCP inverts that, making Kinde the thing that authenticates someone else's agent-facing API. That places the company on the access-control layer for agent traffic rather than only human login, which is a wider surface than passkeys or SAML. The billing work running alongside it suggests Kinde intends to be the monetization-plus-identity layer for a product, not just the sign-in box.

◆ Prediction

Secure MCP is in beta, so the near-term work is most likely general availability plus the scope, consent and token-handling controls that agent access needs. Expect the authentication method list to keep widening in parallel, since that has been the steady cadence all year.
