What is GravityKit?
GravityKit's exporter stops producing files and starts keeping a spreadsheet in sync.
GravityKit ships weekly across a suite of Gravity Forms add-ons, publishing a Launch Log digest alongside dedicated announcements for the larger items. This window covers Google Sheets export in GravityExport, unions in Multiple Forms, rich text inline editing in GravityEdit, and a long tail of Gravity Forms 3.0 and WordPress 7.0 compatibility fixes.
What is Merge?
Merge is turning its weekly integration digest into an agent control plane — the news is always at the bottom.
Merge publishes one dated digest a week, and the structure is consistent: unified Accounting, ATS, CRM, File Storage and HRIS reliability work up top, then Agent Handler and Gateway at the end, where the directional changes live. The feed now also carries per-product breakout entries (Gateway, Unified, Agent Handler) that restate the same week's items in more detail rather than adding new ones. The Agent Handler catalog carries hundreds of generic MCP connectors alongside Merge's own, on shared authentication and policy, and Gateway has been accumulating model coverage, routing controls and guardrails over the same period.
GravityKit vs Merge: editorial side-by-side
GravityKit
6.3INFRA · APIS
GravityKit's exporter stops producing files and starts keeping a spreadsheet in sync.
◆ Current state
GravityKit ships weekly across a suite of Gravity Forms add-ons, publishing a Launch Log digest alongside dedicated announcements for the larger items. This window covers Google Sheets export in GravityExport, unions in Multiple Forms, rich text inline editing in GravityEdit, and a long tail of Gravity Forms 3.0 and WordPress 7.0 compatibility fixes.
◆ Where it's heading
The suite is shifting from displaying form data to moving it. Unions stack entries from several forms into one View, Google Sheets export keeps an external sheet current, and the MCP add-ons in the same window expose theme and entry data to agents. Taken together, Gravity Forms entries are being treated as a data source other systems consume rather than something rendered on a WordPress page.
◆ Prediction
Expect additional live-sync destinations following the Google Sheets pattern, and continued compatibility work while Gravity Forms 3.0 and WordPress 7.0 adoption spreads.
Merge
6.3INFRA · APIS
Merge is turning its weekly integration digest into an agent control plane — the news is always at the bottom.
◆ Current state
Merge publishes one dated digest a week, and the structure is consistent: unified Accounting, ATS, CRM, File Storage and HRIS reliability work up top, then Agent Handler and Gateway at the end, where the directional changes live. The feed now also carries per-product breakout entries (Gateway, Unified, Agent Handler) that restate the same week's items in more detail rather than adding new ones. The Agent Handler catalog carries hundreds of generic MCP connectors alongside Merge's own, on shared authentication and policy, and Gateway has been accumulating model coverage, routing controls and guardrails over the same period.
◆ Where it's heading
The through-line is that Merge is repositioning from data plumbing to the layer agents pass through. Each week adds either reach (more connectors, more tools per connector, more models) or control (guardrails, per-project policy, access configuration). This window is reach-and-efficiency: the GitHub connector expanded to 145 tools, Outlook payloads were cut substantially, and Gateway guardrails became configurable per project rather than per account.
◆ Prediction
Expect the per-project granularity applied to guardrails to spread to the rest of Gateway's controls, and the connector catalog to keep absorbing hosted third-party MCP servers the way Axiom was added.
