GravityKit vs Skipper
A side-by-side editorial comparison of GravityKit and Skipper — release velocity, themes, recent moves, and the top alternatives to consider.
GravityKit vs Skipper: at a glance
What is GravityKit?
GravityKit adds Google Sheets export and Elementor calendar widget — WordPress form data reaches beyond the CMS.
GravityKit is an ecosystem of Gravity Forms extensions for WordPress (GravityView, GravityCalendar, GravityMath, GravityMigrate, GravityExport). The most recent releases add a Google Sheets live export that keeps spreadsheets in sync with Gravity Forms data, a GravityCalendar widget for Elementor, and Multiple Forms unions (stacking entries from multiple forms in a single view). Weekly 'Launch Log' releases ship 3–5 improvements and fixes across the plugin suite.
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.

GravityKit

GravityKit adds Google Sheets export and Elementor calendar widget — WordPress form data reaches beyond the CMS.
◆ Current state
GravityKit is an ecosystem of Gravity Forms extensions for WordPress (GravityView, GravityCalendar, GravityMath, GravityMigrate, GravityExport). The most recent releases add a Google Sheets live export that keeps spreadsheets in sync with Gravity Forms data, a GravityCalendar widget for Elementor, and Multiple Forms unions (stacking entries from multiple forms in a single view). Weekly 'Launch Log' releases ship 3–5 improvements and fixes across the plugin suite.
◆ Where it's heading
GravityKit is expanding the data portability and presentation options for Gravity Forms users: Google Sheets export, Elementor integration, and Multiple Forms unions all extend where form data can go and how it can be displayed. The consistent weekly cadence and security hardening releases (GravityMigrate, GravityRevisions) indicate a mature plugin ecosystem in steady maintenance mode with targeted new capabilities.
◆ Prediction
The Google Sheets export is likely to gain more granular sync controls (webhook triggers, specific column mapping). Additional page builder integrations beyond Elementor are probable given the established pattern.

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.
