GravityKit vs Skipper

GravityKit vs Skipper: at a glance
What is GravityKit?
GravityKit is quietly turning Gravity Forms entries into a cross-form data layer.
Multiple Forms 0.7.0 adds unions — stacking entries from several Gravity Forms forms into one searchable View with no shared field and no code. It arrives alongside rich text inline editing in GravityEdit and GravityView 3.3.0, which carries compatibility fixes for Gravity Forms 3.0 and WordPress 7.0. The weekly Launch Log cadence is steady and covers the whole suite at once: View editor drag-to-copy, accessibility work including screen reader row headers, 3D map viewport loading, DataTables search and security, and Block MCP theme template editing.
What is Skipper?
Skipper tags a release per commit — nine in eight days, and none of them change routing.
Skipper is Zalando's HTTP router and reverse proxy, cut as a GitHub tag on essentially every merged commit: v0.27.42 through v0.27.50 landed inside eight days. The content of that stream is maintenance — dependency group bumps, CI action upgrades, test corrections, and one internal refactor pulling the Valkey Del command and ratelimit ring client injection apart. The single change with user-visible effect in this window is a fix to the proxy listener binding on an insecure address.

GravityKit is quietly turning Gravity Forms entries into a cross-form data layer.
◆ Current state
Multiple Forms 0.7.0 adds unions — stacking entries from several Gravity Forms forms into one searchable View with no shared field and no code. It arrives alongside rich text inline editing in GravityEdit and GravityView 3.3.0, which carries compatibility fixes for Gravity Forms 3.0 and WordPress 7.0. The weekly Launch Log cadence is steady and covers the whole suite at once: View editor drag-to-copy, accessibility work including screen reader row headers, 3D map viewport loading, DataTables search and security, and Block MCP theme template editing.
◆ Where it's heading
Two lines are converging. The first treats form entries as a queryable dataset rather than per-form submissions — GravitySearch's cross-form search, and now unions, both dissolve the boundary between individual forms. The second is an agent surface: GravityKit MCP and Block MCP keep receiving updates, and GravityView 3.0 shipped AI-assisted View creation. A large share of recent releases is also absorbed by keeping the suite compatible with Gravity Forms 3.0 and WordPress 7.0, which sets the pace of everything else.
◆ Prediction
Expect unions to move from the Multiple Forms add-on toward the core View building experience, following the same path cross-form search took. Continued Gravity Forms 3.0 and WordPress 7.0 compatibility fixes will likely dominate the next few Launch Logs.
Skipper
5.0INFRA · APIS
Skipper tags a release per commit — nine in eight days, and none of them change routing.
◆ Current state
Skipper is Zalando's HTTP router and reverse proxy, cut as a GitHub tag on essentially every merged commit: v0.27.42 through v0.27.50 landed inside eight days. The content of that stream is maintenance — dependency group bumps, CI action upgrades, test corrections, and one internal refactor pulling the Valkey Del command and ratelimit ring client injection apart. The single change with user-visible effect in this window is a fix to the proxy listener binding on an insecure address.
◆ Where it's heading
Nothing in these entries points to a direction change; the 0.27 line is in steady maintenance with supply-chain hygiene as the visible priority — oras-go pinned to a released version so osv-scanner stops flagging it, the CodeQL action upgraded, an OPA test hardened to deny requests with truncated bodies. The documentation change is the most revealing item: jwtValidation's behavior was unclear enough to prompt a proposed advisory, and the response was to clarify the docs rather than alter the code.
◆ Prediction
The tag stream will most likely continue at several releases a week with the same composition of dependency bumps and test fixes. These entries show no feature work in flight, so the next notable change is more likely another security-adjacent clarification than a new routing capability.
