What is Ory Hydra?

Hydra's 2.2 candidates rebuilt the OAuth2 flow store, then reached for verifiable credentials

Ory Hydra is a self-hosted OAuth2 and OpenID Connect server. Its visible release record is the v2.2.0 candidate series from 2023, which did two substantial things: rc.2 moved authorization-code flow state out of the database and into AEAD-encrypted cookies and request parameters, a change shipped with an explicit breaking-change notice; rc.3 then added initial OIDC verifiable-credential issuance and wired logout propagation into Ory Kratos. The feed stops at a v2.2.0-pre.1 tag in February 2024.

What is Skipper?

Skipper adds RFC 9421 HTTP Message Signatures and delivers 21% RouteGroup load time improvement

Skipper v0.27 is shipping at a steady maintenance cadence with two functional additions of note: v0.27.96 adds native RFC 9421 HTTP Message Signatures filter support — a 2023 IETF standard for request signing gaining traction in financial services and regulated APIs. v0.27.95 delivers a shared parse cache across RouteGroups, producing a measured 21% load time reduction, 12% lower memory, and 26% fewer allocations on a 200-RouteGroup benchmark.

Hydra's 2.2 candidates rebuilt the OAuth2 flow store, then reached for verifiable credentials

◆ Current state

Ory Hydra is a self-hosted OAuth2 and OpenID Connect server. Its visible release record is the v2.2.0 candidate series from 2023, which did two substantial things: rc.2 moved authorization-code flow state out of the database and into AEAD-encrypted cookies and request parameters, a change shipped with an explicit breaking-change notice; rc.3 then added initial OIDC verifiable-credential issuance and wired logout propagation into Ory Kratos. The feed stops at a v2.2.0-pre.1 tag in February 2024.

◆ Where it's heading

The through-line is reducing per-request database work in the hot authorization path — first by relocating flow state into encrypted client-side material, then by parallelizing JSON web key set generation and adding scope-claim strategies. Running underneath is tighter coupling to the rest of the Ory stack: the Kratos admin URL config and session-termination hook make Hydra less of a standalone component and more of one piece of an integrated identity suite. The verifiable-credentials work is the one thread pointing somewhere genuinely new, and it shipped against a draft specification.

◆ Prediction

The candidate series points toward a v2.2.0 general release consolidating the AEAD flow change and the credential-issuance work. The feed's silence after February 2024 gives no basis for judging when, or whether the draft-stage VC support advanced.

Skipper adds RFC 9421 HTTP Message Signatures and delivers 21% RouteGroup load time improvement

◆ Current state

Skipper v0.27 is shipping at a steady maintenance cadence with two functional additions of note: v0.27.96 adds native RFC 9421 HTTP Message Signatures filter support — a 2023 IETF standard for request signing gaining traction in financial services and regulated APIs. v0.27.95 delivers a shared parse cache across RouteGroups, producing a measured 21% load time reduction, 12% lower memory, and 26% fewer allocations on a 200-RouteGroup benchmark.

◆ Where it's heading

Skipper is building out its security posture at the proxy layer: RFC 9421 request signing, Redis L2 cache (v0.27.92), and security header handling improvements (v0.27.88) suggest a consistent push toward production-grade security primitives without architectural breaks. The performance improvements in v0.27.95 address real-world Kubernetes clusters where large RouteGroup counts are common.

◆ Prediction

RFC 9421 support will likely get expanded configuration options — signing key rotation, policy enforcement modes, per-route key selection — as Zalando's internal adopters surface operational requirements for the filter.
