What is PlanetScale?
PlanetScale ships Database Traffic Control to govern Postgres query loads — and a read-only MCP server for safe agent access.
Recent PlanetScale releases cluster around three themes: a new resource-governance product called Database Traffic Control (with warning thresholds and CLI management), Postgres Postgres infrastructure work (storage configuration at creation, vectorscale extension support, deploy request storage check API), and AI integration plumbing (an Insights-only MCP server variant). The platform also added a GCP region in Eemshaven, Netherlands.
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.

PlanetScale ships Database Traffic Control to govern Postgres query loads — and a read-only MCP server for safe agent access.
◆ Current state
Recent PlanetScale releases cluster around three themes: a new resource-governance product called Database Traffic Control (with warning thresholds and CLI management), Postgres Postgres infrastructure work (storage configuration at creation, vectorscale extension support, deploy request storage check API), and AI integration plumbing (an Insights-only MCP server variant). The platform also added a GCP region in Eemshaven, Netherlands.
◆ Where it's heading
PlanetScale's Postgres offering is moving past parity-with-Vitess functionality and into differentiated territory. Database Traffic Control is the standout — query-level resource budgeting addresses a long-standing operational pain point that no managed Postgres provider has framed quite this way. The Insights-only MCP server is a small but telling move: PlanetScale is shipping deliberately scoped agent endpoints rather than just exposing the full API to LLMs. Postgres feature breadth (vectorscale, storage controls) keeps closing the gap with Neon and Supabase.
◆ Prediction
Expect Database Traffic Control to gain alerting and rollout-staged enforcement in the next quarter, plus deeper integration with Insights so customers can map costly queries directly to budget-violation events. More extensions on Postgres are likely (pgvector enhancements, tuning extensions). The MCP server pattern will probably grow into other scoped variants — schema-editing-only, ops-only — as PlanetScale formalizes how agents touch production databases.

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.
