What is Obsidian?

Obsidian's recent cycle is quiet maintenance, with CLI tooling the main bright spot.

Obsidian's latest releases are largely maintenance rollups (v1.12.x through v1.13.1) and bug fixes. The one substantive thread is its command-line tooling: a new bundled CLI binary for faster terminal interactions and TUI command autocompletion.

What is Ably?

Ably builds an AI agent transport on top of its realtime stack — human-in-the-loop and branching land in v0.3

Ably is shipping steady client-SDK maintenance (JS, Cocoa, Dart, CLI) while standing up a new product line: an AI Transport SDK that carries agent conversation streams over its realtime infrastructure. Recent SDK releases improve React channel-hook ergonomics and LiveObjects dashboard visibility, but the distinctive motion is the AI Transport work.

Obsidian vs Ably: editorial side-by-side

2.5

Obsidian's recent cycle is quiet maintenance, with CLI tooling the main bright spot.

◆ Current state

Obsidian's latest releases are largely maintenance rollups (v1.12.x through v1.13.1) and bug fixes. The one substantive thread is its command-line tooling: a new bundled CLI binary for faster terminal interactions and TUI command autocompletion.

◆ Where it's heading

Beyond steady stability work, Obsidian is investing in CLI and TUI ergonomics, signaling interest in scriptable, terminal-driven workflows for power users. The cadence of user-facing feature work in this window is low.

◆ Prediction

Expect continued incremental stability releases and further CLI and TUI refinement; nothing in these entries points to a larger directional shift.

Ably builds an AI agent transport on top of its realtime stack — human-in-the-loop and branching land in v0.3

◆ Current state

Ably is shipping steady client-SDK maintenance (JS, Cocoa, Dart, CLI) while standing up a new product line: an AI Transport SDK that carries agent conversation streams over its realtime infrastructure. Recent SDK releases improve React channel-hook ergonomics and LiveObjects dashboard visibility, but the distinctive motion is the AI Transport work.

◆ Where it's heading

The clear direction is extending Ably's pub/sub and LiveObjects primitives into agentic, real-time AI sessions — session/run models, branching conversations, and human-in-the-loop handoff. The mature client SDKs are being kept stable and incrementally improved while the AI transport layer is where new capability is concentrating.

◆ Prediction

Expect the AI Transport SDK to march toward a 1.0 with tighter integration of Presence and LiveObjects into agent sessions, while the core client libraries continue their fix-and-refine cadence.
