GravityKit vs LibreSpeed
A side-by-side editorial comparison of GravityKit and LibreSpeed — release velocity, themes, recent moves, and the top alternatives to consider.
GravityKit vs LibreSpeed: at a glance
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.
What is LibreSpeed?
After a two-year redesign, LibreSpeed is adding tests instead of polishing pixels.
LibreSpeed is a self-hosted speed test that spent roughly two years landing a new frontend design, shipped it behind a feature switch, then promoted it to default in 6.0.0. With that out of the way, 6.2.0 turns to capability: a standalone connection-stability test with live latency charting, packet-loss tracking, alerts and CSV export, plus PWA metadata so the tool can be installed from a browser. Docker deployment has been reworked in parallel, including a port change and PHP limits that were silently rejecting default upload chunks.

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.
LibreSpeed
2.5INFRA · APIS
After a two-year redesign, LibreSpeed is adding tests instead of polishing pixels.
◆ Current state
LibreSpeed is a self-hosted speed test that spent roughly two years landing a new frontend design, shipped it behind a feature switch, then promoted it to default in 6.0.0. With that out of the way, 6.2.0 turns to capability: a standalone connection-stability test with live latency charting, packet-loss tracking, alerts and CSV export, plus PWA metadata so the tool can be installed from a browser. Docker deployment has been reworked in parallel, including a port change and PHP limits that were silently rejecting default upload chunks.
◆ Where it's heading
The redesign was the blocker; now that it is default, releases are moving outward — a second measurement mode, installability, better multi-server list handling. The Docker thread runs alongside and is where the breaking changes live: default port moved from 80 to 8080 in preparation for rootless operation, post_max_size raised to accept the tool's own 20 MiB chunks, Alpine base updated. Much of the recent throughput comes from outside contributors and automated agents rather than a single maintainer.
◆ Prediction
Expect the stability test to gain the configuration and server-side plumbing the main speed test already has, and the rootless-container work that the port change was preparation for to land next. Nothing in the entries suggests a change to the project's self-hosted, no-backend-dependency positioning.
