GravityKit vs Windmill: at a glance
What is GravityKit?
GravityKit makes Gravity Forms merge tags readable chips you can preview before saving.
GravityKit ships a weekly Launch Log across its Gravity Forms add-ons. Early October brought Visual Merge Tags in Foundation 1.35.0, turning raw merge tags into editable chips previewed against real entries. Later weeks added AI-built boards, AI-managed calendars, a range-slider search, live DataTables totals and a steady stream of security fixes across the suite.
What is Windmill?
Windmill adds workspace roles and AI decision steps as its agent tooling fills out.
Windmill is an open-source workflow and internal-tools platform adding AI and governance features quickly. Mid-September brought a headless Chat SDK for chat-mode flows, per-run tool selection for AI agent steps, origin allowlists for HTTP routes, GitHub CI gating and GitLab git-sync parity. October added an AI decision step, operator builder rights and default Developer and Operator workspace roles.

GravityKit makes Gravity Forms merge tags readable chips you can preview before saving.
◆ Current state
GravityKit ships a weekly Launch Log across its Gravity Forms add-ons. Early October brought Visual Merge Tags in Foundation 1.35.0, turning raw merge tags into editable chips previewed against real entries. Later weeks added AI-built boards, AI-managed calendars, a range-slider search, live DataTables totals and a steady stream of security fixes across the suite.
◆ Where it's heading
The suite is moving in two directions at once: making Gravity Forms configuration less cryptic for site builders, and letting AI assistants operate its products through MCP. Security fixes appear in most weekly logs, a sign of a large plugin surface under active review.
◆ Prediction
Expect more GravityKit products to gain AI-assistant control and weekly security patches; whether Visual Merge Tags spreads to other plugins' settings is unclear.

Windmill adds workspace roles and AI decision steps as its agent tooling fills out.
◆ Current state
Windmill is an open-source workflow and internal-tools platform adding AI and governance features quickly. Mid-September brought a headless Chat SDK for chat-mode flows, per-run tool selection for AI agent steps, origin allowlists for HTTP routes, GitHub CI gating and GitLab git-sync parity. October added an AI decision step, operator builder rights and default Developer and Operator workspace roles.
◆ Where it's heading
Windmill is building AI agents into flows as first-class steps with controls over which tools they can use, while adding the role and access model enterprises need to let more people build. Developer workflow parity across Git hosts continues in parallel.
◆ Prediction
Expect more AI agent controls and role-based permissions; whether the Chat SDK grows into a hosted chat product is unclear.
