What is Ably?
Ably is building an agent transport layer on its realtime core, shipping AI SDK versions every ten days.
Two release trains run side by side in this feed. The AI Transport SDK is moving fast and pre-1.0 — durable execution in 0.5.0, mid-run steering in 0.6.0, an OpenAI Responses codec in 0.7.0, each roughly ten days apart and each carrying breaking changes. The Pub/Sub and Java SDKs move at a steadier pace, working through LiveObjects reach, React and React Native support, and now connectivity fallbacks.
What is Testomat.io?
Testomat is closing the loop from failing test to tracked defect, one quarterly digest at a time
Testomat ships in large periodic digests rather than continuous drops, and each one pairs a structural addition with a batch of interface work. The August release adds a per-project Defects page listing the bug-tracker issues raised against failing tests, plus defects in analytics, milestone insights, and comment mentions. Underneath it, the past year laid down Requirements, Milestones, a Public API v2, and an MCP server.

Ably

Ably is building an agent transport layer on its realtime core, shipping AI SDK versions every ten days.
◆ Current state
Two release trains run side by side in this feed. The AI Transport SDK is moving fast and pre-1.0 — durable execution in 0.5.0, mid-run steering in 0.6.0, an OpenAI Responses codec in 0.7.0, each roughly ten days apart and each carrying breaking changes. The Pub/Sub and Java SDKs move at a steadier pace, working through LiveObjects reach, React and React Native support, and now connectivity fallbacks.
◆ Where it's heading
Ably is treating agent conversations as a transport problem — sessions, resumability, and multi-client reconciliation — rather than as a model-integration problem, and the primitives shipping in AI Transport keep pointing that way. The Pub/Sub line is being pulled along behind it: LiveObjects path APIs and React hooks are the state layer those agent sessions need. The pre-1.0 SDK will keep breaking as the shape settles, which is a reasonable trade while the category is unsettled.
◆ Prediction
Expect AI Transport to keep adding provider codecs beyond OpenAI Responses and to approach an API freeze as breaking changes get more expensive. LiveObjects support should continue spreading across the language SDKs, following the Java path-based API with other platforms.
Testomat.io

Testomat is closing the loop from failing test to tracked defect, one quarterly digest at a time
◆ Current state
Testomat ships in large periodic digests rather than continuous drops, and each one pairs a structural addition with a batch of interface work. The August release adds a per-project Defects page listing the bug-tracker issues raised against failing tests, plus defects in analytics, milestone insights, and comment mentions. Underneath it, the past year laid down Requirements, Milestones, a Public API v2, and an MCP server.
◆ Where it's heading
Two arcs run in parallel here. One is structural test management — Requirements, Milestones, tree navigation, plans — filling out what a QA team needs to run a release cycle rather than just store cases. The other is machine access: an MCP server, a v2 public API, AI quality review, AI test-data suggestions, and an analytics chat, which together make the test corpus readable by something other than a person clicking through the UI. Defects is where the first arc finally reaches the bug tracker.
◆ Prediction
The next digest most likely deepens the defect loop, linking defect state back to test status or analytics, since that is the newest structural piece and currently a listing rather than a workflow. The API and MCP thread points at more agent-facing surface, though these entries do not indicate what it would cover.
