Windmill vs GravityKit: at a glance
What is Windmill?
Windmill keeps turning AI clients into the place you build and run its workflows.
Windmill has spent the last six weeks wiring AI into every layer: standalone agents, compaction memory, an AI decision step, Slack-answering agents, and a single /api/mcp endpoint that lets Claude, ChatGPT or Cursor write, test and deploy workspace code. Alongside that it is formalizing who can do what, with default Developer and Operator roles and seat-priced operator build rights. The latest release, Tailwind v4 compilation for full-code apps, is frontend plumbing that makes those apps easier to style.
What is GravityKit?
GravityKit folds every GravityView extension into one Pro plugin.
GravityKit ships a weekly Launch Log across its Gravity Forms add-ons, mostly security fixes and small field options. The November 12 release bundles every GravityView extension and layout into one Pro plugin with Live Filters, Connected Views and an Edit Window; the November 13 log adds paid, ranked Featured Tiers, a Pages with this View menu and more security fixes. October's notable items were Visual Merge Tags, AI-built boards and AI-managed calendars.

Windmill

Windmill keeps turning AI clients into the place you build and run its workflows.
◆ Current state
Windmill has spent the last six weeks wiring AI into every layer: standalone agents, compaction memory, an AI decision step, Slack-answering agents, and a single /api/mcp endpoint that lets Claude, ChatGPT or Cursor write, test and deploy workspace code. Alongside that it is formalizing who can do what, with default Developer and Operator roles and seat-priced operator build rights. The latest release, Tailwind v4 compilation for full-code apps, is frontend plumbing that makes those apps easier to style.
◆ Where it's heading
The direction is clear: Windmill wants to be the execution backend that AI clients drive, not just a UI people click through. MCP moved from a tool list to a build-and-deploy surface, then to interactive cards inside the chat. The roles and seat changes suggest it is preparing to price the wider set of people who can now build through AI.
◆ Prediction
Expect more of the deploy and review lifecycle to surface inside MCP clients, and finer-grained role controls over which MCP tools each role gets.
GravityKit
5.0INFRA · APIS
GravityKit folds every GravityView extension into one Pro plugin.
◆ Current state
GravityKit ships a weekly Launch Log across its Gravity Forms add-ons, mostly security fixes and small field options. The November 12 release bundles every GravityView extension and layout into one Pro plugin with Live Filters, Connected Views and an Edit Window; the November 13 log adds paid, ranked Featured Tiers, a Pages with this View menu and more security fixes. October's notable items were Visual Merge Tags, AI-built boards and AI-managed calendars.
◆ Where it's heading
GravityKit is consolidating a sprawl of separate add-ons into fewer, larger products while steadily adding AI-assistant hooks to individual tools. Paid Featured Tiers suggest the Pro bundle is also a vehicle for listing and directory use cases.
◆ Prediction
Expect the weekly logs to continue with security fixes, and more products to follow GravityView into bundled editions.
