What is Statsig?
Statsig opens an agent-skills repo and broadens MCP, betting on AI agents as a primary user surface.
Statsig is treating AI coding agents (Claude, Cursor, Codex) as first-class consumers of the platform. The recent push includes a public agent-skills repository (reusable Statsig skills agents can install), MCP coverage extended to Segments and Layers so targeting and experiment config are now agent-driveable, and a private-beta Console API for generating dashboards programmatically. Alongside that, the analytics surface keeps gaining quality-of-life primitives: cancellable Metrics Explorer queries, Lifecycle Charts, Dashboard Pages.
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.

Statsig

Statsig opens an agent-skills repo and broadens MCP, betting on AI agents as a primary user surface.
◆ Current state
Statsig is treating AI coding agents (Claude, Cursor, Codex) as first-class consumers of the platform. The recent push includes a public agent-skills repository (reusable Statsig skills agents can install), MCP coverage extended to Segments and Layers so targeting and experiment config are now agent-driveable, and a private-beta Console API for generating dashboards programmatically. Alongside that, the analytics surface keeps gaining quality-of-life primitives: cancellable Metrics Explorer queries, Lifecycle Charts, Dashboard Pages.
◆ Where it's heading
The bet is that experimentation, feature flags, and product analytics work increasingly happens through an agent — engineers asking Claude or Cursor to set up a flag, build a dashboard, or check an experiment, rather than navigating Statsig's UI directly. Each release is either widening MCP coverage or making the underlying primitives agent-shaped (Console API for dashboards, shareable metric outputs, query cancellation to keep agent workloads from blowing up warehouse spend).
◆ Prediction
Expect MCP coverage to keep filling out — experiments, gates, holdouts — and the agent-skills repo to become a community surface with sample skills from common LLM agents. Pricing or guardrails around agent-driven warehouse query volume are an increasingly likely follow-on.
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.
