Gatekeeper vs GravityKit
A side-by-side editorial comparison of Gatekeeper and GravityKit — release velocity, themes, recent moves, and the top alternatives to consider.
Gatekeeper vs GravityKit: at a glance
What is Gatekeeper?
Gatekeeper grew a package manager for policies — and a benchmark to prove they are not too slow.
3.22.0-rc.0 in February introduced two CLI subcommands that change how policies are handled rather than what they express: gator policy, a brew-inspired tool for discovering, installing, upgrading and uninstalling policies from the gatekeeper-library, and gator bench, which benchmarks Rego and CEL engines with latency percentiles, throughput, memory profiling and baseline comparison for CI regression detection. The same release enabled sync-vap-enforcement-scope by default and gave both CEL and Rego access to namespace context during admission and audit. Since then, 3.23.0-rc.1 added status resource routing for remote cluster mode, and 3.24.0-beta.0 made generated ValidatingAdmissionPolicy output deterministic to stop a reconcile loop.
What is GravityKit?
GravityKit ships weekly across a whole plugin suite, with an MCP server now part of the lineup.
GravityKit publishes a weekly Launch Log covering releases across its Gravity Forms add-on suite — GravityView, GravityEdit, GravityCalendar, GravityCharts, GravityImport, DataTables, Maps, Multiple Forms, Zero Spam, and a Block MCP server. Recent weeks delivered union support for combining entries from multiple forms into one View, rich text inline editing, drag-to-copy in the View editor, and 3D map viewport work. A large share of every week's notes is Gravity Forms 3.0 and WordPress 7.0 compatibility work.

Gatekeeper
2.5INFRA · APIS
Gatekeeper grew a package manager for policies — and a benchmark to prove they are not too slow.
◆ Current state
3.22.0-rc.0 in February introduced two CLI subcommands that change how policies are handled rather than what they express: gator policy, a brew-inspired tool for discovering, installing, upgrading and uninstalling policies from the gatekeeper-library, and gator bench, which benchmarks Rego and CEL engines with latency percentiles, throughput, memory profiling and baseline comparison for CI regression detection. The same release enabled sync-vap-enforcement-scope by default and gave both CEL and Rego access to namespace context during admission and audit. Since then, 3.23.0-rc.1 added status resource routing for remote cluster mode, and 3.24.0-beta.0 made generated ValidatingAdmissionPolicy output deterministic to stop a reconcile loop.
◆ Where it's heading
The centre of gravity is moving from the admission controller to the tooling around it. Policies are becoming artefacts you install from a library at a version, benchmark against a baseline in CI, and test before they reach a cluster — which is the lifecycle application code already has and policy generally has not. Underneath, the ValidatingAdmissionPolicy path keeps maturing as Gatekeeper hands more enforcement to the Kubernetes-native mechanism it now generates.
◆ Prediction
Remote cluster mode gained status routing but the entries describe only that piece, so how far multi-cluster enforcement extends is unclear from these notes. The releases in this window are all beta and release candidates, so a 3.24.0 stable is the near-term milestone.
GravityKit
5.0INFRA · APIS
GravityKit ships weekly across a whole plugin suite, with an MCP server now part of the lineup.
◆ Current state
GravityKit publishes a weekly Launch Log covering releases across its Gravity Forms add-on suite — GravityView, GravityEdit, GravityCalendar, GravityCharts, GravityImport, DataTables, Maps, Multiple Forms, Zero Spam, and a Block MCP server. Recent weeks delivered union support for combining entries from multiple forms into one View, rich text inline editing, drag-to-copy in the View editor, and 3D map viewport work. A large share of every week's notes is Gravity Forms 3.0 and WordPress 7.0 compatibility work.
◆ Where it's heading
Two things define this suite right now. First, it is absorbing a major upstream break: Gravity Forms 3.0 fixes appear in nearly every Launch Log, which sets the pace regardless of what the roadmap wanted. Second, the View editor is becoming a data-composition tool rather than a display configurator — unions across forms, field-to-field filtering, distance sorting on radius searches, and searchable DataTables all point at users assembling application-like views over form data. Accessibility shows up consistently too, with row headers for screen readers and editor a11y upgrades.
◆ Prediction
Expect Gravity Forms 3.0 and WordPress 7.0 compatibility to keep consuming release capacity until the upstream transition settles, with union and filtering work continuing on the View editor underneath it. The Block MCP server is the piece to watch — it is the only part of the suite aimed at agents rather than site builders.
