What is Dust?
Dust doubles down on MCP-native agents with multi-model routing and enterprise guardrails.
Dust is building an MCP-native agent platform with broad model coverage and growing enterprise depth. The May cadence shows parallel investment in agent capability (vision via MCP tools, context compaction, frame editing/export) and operational readiness (audit logs, SIEM streaming, protocol migrations). Mobile is getting a voice-first input redesign.
What is Ably?
Ably is bending its realtime stack toward AI-agent transport
Ably keeps shipping across its full SDK matrix — JS, Cocoa, Dart, Chat — while concentrating its newest energy on an AI Transport JS SDK that has moved from v0.2 to v0.4 in under two months. The core Pub/Sub and LiveObjects surfaces get steady maintenance plus new dashboard visibility work.
Dust vs Ably: editorial side-by-side
Dust
8.8INFRA · APIS
Dust doubles down on MCP-native agents with multi-model routing and enterprise guardrails.
◆ Current state
Dust is building an MCP-native agent platform with broad model coverage and growing enterprise depth. The May cadence shows parallel investment in agent capability (vision via MCP tools, context compaction, frame editing/export) and operational readiness (audit logs, SIEM streaming, protocol migrations). Mobile is getting a voice-first input redesign.
◆ Where it's heading
The product is converging on agents-in-the-enterprise via MCP, with multi-model routing as table stakes. MCP V2 migrations and image returns from MCP tools point to the protocol becoming Dust's integration backbone. The model-refresh cadence — three vendors in 48 hours — suggests model routing is now a core competency, not a feature.
◆ Prediction
Expect more MCP V2 connector migrations and richer MCP return types beyond images. The voice-first mobile input bar likely precedes a deeper voice-mode agent surface.

Ably is bending its realtime stack toward AI-agent transport
◆ Current state
Ably keeps shipping across its full SDK matrix — JS, Cocoa, Dart, Chat — while concentrating its newest energy on an AI Transport JS SDK that has moved from v0.2 to v0.4 in under two months. The core Pub/Sub and LiveObjects surfaces get steady maintenance plus new dashboard visibility work.
◆ Where it's heading
The AI Transport SDK is where Ably is placing its directional bet: session/run models, branching conversations, human-in-the-loop handoff, and now external data hydration all point at owning the realtime layer for agent applications. In parallel the mainline JS client is formalizing React-first ergonomics and deprecating its v1 callback API.
◆ Prediction
Expect the AI Transport SDK to hold its rapid cadence toward a 1.0, and the newly released Dart SDK to follow the same early-adoption-to-stable path.
