What is Ably?
Ably's AI Transport hits 1.0 and plugs straight into Vercel's useChat with resumable streams.
Ably is repositioning its realtime pub/sub network as the transport layer for AI agent output. AI Transport JS 1.0 runs on ordinary Pub/Sub channels and ships adaptors for the Vercel AI SDK, OpenAI Responses API and AG-UI, plus a useChat transport that resumes a stream after a reload. It lands a week after the switch to monthly-active-user pricing and breaking SDK majors that split every client into device and server packages.
What is Drone?
Drone's source now ships as Harness Open Source, and it last released in August 2025.
Both tracked releases are tagged Harness Open Source from the harness/harness repo, which is where Drone's code now lives. v3.2.0 added Git LFS, PR revert, retargeting and Code Owner auto-assignment; v3.3.0 added favorite repos, tag protection rules and a fix for a Git LFS path-traversal issue. Nothing has shipped since August 2025.

Ably
7.5INFRA · APIS
Ably's AI Transport hits 1.0 and plugs straight into Vercel's useChat with resumable streams.
◆ Current state
Ably is repositioning its realtime pub/sub network as the transport layer for AI agent output. AI Transport JS 1.0 runs on ordinary Pub/Sub channels and ships adaptors for the Vercel AI SDK, OpenAI Responses API and AG-UI, plus a useChat transport that resumes a stream after a reload. It lands a week after the switch to monthly-active-user pricing and breaking SDK majors that split every client into device and server packages.
◆ Where it's heading
The November releases fit one plan: split clients so MAU billing can count end users, then make the AI layer a thin adaptor on top of the same channels used for chat, presence and LiveObjects. Server-side additions in Java and JS (HTTP LiveObjects, channel pools, a Temporal plugin) point at agent backends as the intended publisher.
◆ Prediction
Expect more agent framework adaptors and server SDKs reaching AI Transport parity, with Chat and LiveObjects examples built around agents joining human conversations.
Drone
0.0INFRA · APIS
Drone's source now ships as Harness Open Source, and it last released in August 2025.
◆ Current state
Both tracked releases are tagged Harness Open Source from the harness/harness repo, which is where Drone's code now lives. v3.2.0 added Git LFS, PR revert, retargeting and Code Owner auto-assignment; v3.3.0 added favorite repos, tag protection rules and a fix for a Git LFS path-traversal issue. Nothing has shipped since August 2025.
◆ Where it's heading
The product has moved from a CI engine toward a full code-hosting platform with PR workflows and branch/tag governance. The 14-month gap since v3.3.0 points to slow or paused open-source releases.
◆ Prediction
The entries give no sign of a next release; another quiet period is the base case.
