What is Knock?
Knock is wiring both ends of the messaging data loop, then putting an agent on top
Knock has spent the last month building around its notification engine rather than inside it. Two new inbound data sources, Amplitude and Clay, let product events, cohorts, and enriched account rows land in Knock without customers writing sync code, while message and engagement events flow back out to the warehouse. The dashboard work alongside it, a rebuilt template editor, saved views and tags, schema management, and passkeys, reads as hardening for teams rather than individual developers.
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.

Knock is wiring both ends of the messaging data loop, then putting an agent on top
◆ Current state
Knock has spent the last month building around its notification engine rather than inside it. Two new inbound data sources, Amplitude and Clay, let product events, cohorts, and enriched account rows land in Knock without customers writing sync code, while message and engagement events flow back out to the warehouse. The dashboard work alongside it, a rebuilt template editor, saved views and tags, schema management, and passkeys, reads as hardening for teams rather than individual developers.
◆ Where it's heading
The direction is away from a notification API you call and toward the system that holds the messaging state. Ingesting cohort membership and enriched contact data is CDP-adjacent territory, and the wait-for-event function turns linear sequences into event-driven orchestration. The Knock agent then adds a natural-language layer over performance data, so the platform answers questions instead of only exporting rows.
◆ Prediction
Expect more data sources on the same pattern, warehouse and CRM-side connectors that keep audiences in sync without customer glue code. Whether the agent moves from reading analytics to editing workflows directly is the open question these entries do not yet answer.
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.
