What is v0 by Vercel?
v0 is turning its app builder into an agentic, programmable full-stack dev platform.
v0 has moved well past UI generation: the agent now runs terminal commands, resolves PR merge conflicts, writes SQL in DB Studio, and tests its own previews with browser screenshots. The June 8 release added a four-tier model picker topped by Claude Opus 4.8, plus Shopify and Snowflake integrations and a Neon/Drizzle/Better Auth default stack. With Platform API v2 and an MCP server, v0 is now something other tools and agents can call, not just a place you visit.
What is Ably?
Ably is bending its realtime stack toward AI-agent transport
Ably keeps shipping across its full SDK matrix — JS, Cocoa, Dart, Chat — while concentrating its newest energy on an AI Transport JS SDK that has moved from v0.2 to v0.4 in under two months. The core Pub/Sub and LiveObjects surfaces get steady maintenance plus new dashboard visibility work.

v0 is turning its app builder into an agentic, programmable full-stack dev platform.
◆ Current state
v0 has moved well past UI generation: the agent now runs terminal commands, resolves PR merge conflicts, writes SQL in DB Studio, and tests its own previews with browser screenshots. The June 8 release added a four-tier model picker topped by Claude Opus 4.8, plus Shopify and Snowflake integrations and a Neon/Drizzle/Better Auth default stack. With Platform API v2 and an MCP server, v0 is now something other tools and agents can call, not just a place you visit.
◆ Where it's heading
The throughline is v0 becoming full-stack and programmable. Each recent release widened what the agent can do on its own (commands, conflict resolution, database work) while June's API and MCP additions expose that capability to external callers. The product is positioning as the execution layer for app generation, with data integrations like Snowflake, Shopify, and Neon as the surface it builds against.
◆ Prediction
Expect Platform API v2 to leave beta with broader chat-control endpoints and the MCP server to grow toward letting external agents drive full build-deploy loops. More first-class data and auth integrations are the likely next additions, given the repeated Neon/Snowflake/Shopify pattern.

Ably is bending its realtime stack toward AI-agent transport
◆ Current state
Ably keeps shipping across its full SDK matrix — JS, Cocoa, Dart, Chat — while concentrating its newest energy on an AI Transport JS SDK that has moved from v0.2 to v0.4 in under two months. The core Pub/Sub and LiveObjects surfaces get steady maintenance plus new dashboard visibility work.
◆ Where it's heading
The AI Transport SDK is where Ably is placing its directional bet: session/run models, branching conversations, human-in-the-loop handoff, and now external data hydration all point at owning the realtime layer for agent applications. In parallel the mainline JS client is formalizing React-first ergonomics and deprecating its v1 callback API.
◆ Prediction
Expect the AI Transport SDK to hold its rapid cadence toward a 1.0, and the newly released Dart SDK to follow the same early-adoption-to-stable path.
