What is Windsurf?
Windsurf is folding Devin into every surface — IDE, terminal, and a new local agent.
Windsurf, Cognition's AI IDE, is mid-merge with Devin. The 2.0 launch put Devin Cloud inside the editor; the late-April releases pushed further: Devin for Terminal (a Rust-written multi-model CLI agent shipped to all subscribers), a new Devin Local agent harness inside Windsurf claimed to be 30% more token-efficient than the original Cascade agent, and now Devin Review & Quick Review tooling. Frontier-model coverage is being kept current — GPT-5.5 and Claude Opus 4.7 both landed in April. The Agent Command Center continues to mature with kanban views, Spaces, and inbox refinements.
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.

Windsurf is folding Devin into every surface — IDE, terminal, and a new local agent.
◆ Current state
Windsurf, Cognition's AI IDE, is mid-merge with Devin. The 2.0 launch put Devin Cloud inside the editor; the late-April releases pushed further: Devin for Terminal (a Rust-written multi-model CLI agent shipped to all subscribers), a new Devin Local agent harness inside Windsurf claimed to be 30% more token-efficient than the original Cascade agent, and now Devin Review & Quick Review tooling. Frontier-model coverage is being kept current — GPT-5.5 and Claude Opus 4.7 both landed in April. The Agent Command Center continues to mature with kanban views, Spaces, and inbox refinements.
◆ Where it's heading
Cognition is consolidating Devin and Windsurf into a single agent stack with three entry points: terminal, IDE, and cloud VM. The same agent harness now powers all three. Strategic direction is clear — Cascade, the original Windsurf agent, is being phased out in favor of the Devin harness that's measurably cheaper per token. Frontier-model neutrality (Opus 4.7, GPT-5.5, SWE-1.6 all named) keeps Windsurf positioned as a multi-model client even as Anthropic and OpenAI push their own coding products.
◆ Prediction
Expect a Cascade-to-Devin migration to be made automatic or default in the next minor — the team won't run two agent harnesses in parallel forever once one is meaningfully more efficient. The Devin Review tooling shipped this week likely expands into PR-level review on GitHub directly, since Cognition has both the Devin Cloud infrastructure and the IDE relationship to wire that up.
Ably
6.3INFRA · APIS
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.
