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 patches its second filter advisory in a week, this one in the OPA request-body filter.
Skipper keeps tagging one release per merge. v0.28.46 fixes advisory GHSA-j3r3-rjcc-vh4q in the opaAuthorizeRequestWithBody filter, reported by an outside researcher, a week after the cache() advisory fix. Between them came v0.28.40's priority routes for binary users, raw-path predicates, and fixes for a JWT cache leak, a headerToQuery bug and an AWS signer data race; v0.28.45 only repairs CI test targets.

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
5.0INFRA · APIS
Skipper patches its second filter advisory in a week, this one in the OPA request-body filter.
◆ Current state
Skipper keeps tagging one release per merge. v0.28.46 fixes advisory GHSA-j3r3-rjcc-vh4q in the opaAuthorizeRequestWithBody filter, reported by an outside researcher, a week after the cache() advisory fix. Between them came v0.28.40's priority routes for binary users, raw-path predicates, and fixes for a JWT cache leak, a headerToQuery bug and an AWS signer data race; v0.28.45 only repairs CI test targets.
◆ Where it's heading
Security hardening at the routing layer is the main thread: outside researchers are reporting filter-level advisories, and the maintainers are answering with fixes plus tools like priority routes that let operators block suspicious paths before any backend sees them. Around that, correctness fixes for concurrency and lifecycle bugs keep landing one tag at a time, and CI coverage is being repaired so race tests actually run.
◆ Prediction
Expect more advisory fixes in filters that inspect request bodies or paths, and more single-fix tags. The entries don't say whether the advisory details will be published with them.
