What is Microcks?

Microcks is quietly wiring LLM example generation into an API mocking tool built for Kubernetes.

Three release candidates are visible — 1.14.0-rc1 and rc2 in March 2026, then 1.15.0-rc1 in June. The 1.14 line added Sync-to-Async triggers with trigger info propagated to the async minion, pushed the Helm chart as an OCI artifact, fixed API health checks under bad connection configuration, and extended OpenAI-based example generation to the GPT-5 family. 1.15.0-rc1 is largely platform upkeep: Angular upgraded to v21, netty explicitly embedded in the native image, GraphQL extensions, paginated topic ARN lookup, and a corrected OpenAPI overlay export shape.

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.

Microcks is quietly wiring LLM example generation into an API mocking tool built for Kubernetes.

◆ Current state

Three release candidates are visible — 1.14.0-rc1 and rc2 in March 2026, then 1.15.0-rc1 in June. The 1.14 line added Sync-to-Async triggers with trigger info propagated to the async minion, pushed the Helm chart as an OCI artifact, fixed API health checks under bad connection configuration, and extended OpenAI-based example generation to the GPT-5 family. 1.15.0-rc1 is largely platform upkeep: Angular upgraded to v21, netty explicitly embedded in the native image, GraphQL extensions, paginated topic ARN lookup, and a corrected OpenAPI overlay export shape.

◆ Where it's heading

Two threads run in parallel. The deployment story keeps getting tightened for Kubernetes — OCI-packaged Helm charts, native-image reflection registration, an Uber distribution — which is where a mock server has to live to be useful in CI. The more interesting thread is example generation: authoring realistic mock data is the actual work of using a mocking tool, and Microcks is putting a model behind it rather than asking users to write it. That work is still surfacing as commit lines rather than headline features.

◆ Prediction

The 1.15 line should reach a final release given the pre-release pattern, and the LLM example generation is the thread most likely to move from plumbing to a named capability if it keeps expanding.

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.
