What is Ably?

Ably's AI Transport SDK integrates Temporal for durable agent sessions, moving beyond pure message transport

Ably is building out a dedicated realtime infrastructure layer for AI agent workloads. The AI Transport SDK has matured through several releases: mid-run steering, OpenAI Responses API support, and now durable execution via Temporal. In parallel, LiveObjects — its shared state primitive for collaborative and agent state — graduated from experimental to stable in the Cocoa SDK, and the Terraform provider received a major capability expansion.

What is GravityKit?

GravityKit adds Google Sheets export and Elementor calendar widget — WordPress form data reaches beyond the CMS.

GravityKit is an ecosystem of Gravity Forms extensions for WordPress (GravityView, GravityCalendar, GravityMath, GravityMigrate, GravityExport). The most recent releases add a Google Sheets live export that keeps spreadsheets in sync with Gravity Forms data, a GravityCalendar widget for Elementor, and Multiple Forms unions (stacking entries from multiple forms in a single view). Weekly 'Launch Log' releases ship 3–5 improvements and fixes across the plugin suite.

Ably's AI Transport SDK integrates Temporal for durable agent sessions, moving beyond pure message transport

◆ Current state

Ably is building out a dedicated realtime infrastructure layer for AI agent workloads. The AI Transport SDK has matured through several releases: mid-run steering, OpenAI Responses API support, and now durable execution via Temporal. In parallel, LiveObjects — its shared state primitive for collaborative and agent state — graduated from experimental to stable in the Cocoa SDK, and the Terraform provider received a major capability expansion.

◆ Where it's heading

Ably is positioning itself as the realtime infrastructure specifically designed for AI agent workloads — not just message passing but full agent lifecycle management: durable sessions, shared state, mid-run steering, and transport across any AI SDK. The pattern across releases is consistent: each ships one more agent lifecycle primitive that previously required custom implementation.

◆ Prediction

Expect Ably to deepen observability tooling for agent sessions — conversation history, run health analytics — and expand the Temporal integration to additional AI frameworks beyond Vercel AI SDK. LiveObjects graduating to stable likely unlocks broader multi-agent coordination use cases; look for examples or patterns around agents sharing state through LiveObjects.

5.0

GravityKit adds Google Sheets export and Elementor calendar widget — WordPress form data reaches beyond the CMS.

◆ Current state

GravityKit is an ecosystem of Gravity Forms extensions for WordPress (GravityView, GravityCalendar, GravityMath, GravityMigrate, GravityExport). The most recent releases add a Google Sheets live export that keeps spreadsheets in sync with Gravity Forms data, a GravityCalendar widget for Elementor, and Multiple Forms unions (stacking entries from multiple forms in a single view). Weekly 'Launch Log' releases ship 3–5 improvements and fixes across the plugin suite.

◆ Where it's heading

GravityKit is expanding the data portability and presentation options for Gravity Forms users: Google Sheets export, Elementor integration, and Multiple Forms unions all extend where form data can go and how it can be displayed. The consistent weekly cadence and security hardening releases (GravityMigrate, GravityRevisions) indicate a mature plugin ecosystem in steady maintenance mode with targeted new capabilities.

◆ Prediction

The Google Sheets export is likely to gain more granular sync controls (webhook triggers, specific column mapping). Additional page builder integrations beyond Elementor are probable given the established pattern.
