Side-by-side trajectory, velocity, and editorial themes.
Retool fills in its AI-native React app builder
Retool's recent work orbits its new app builder, which lets teams generate production-ready React apps from natural language, MCP-compatible coding agents, or imported React code. The latest entries fill in that builder with React import and app protection, while the rest is admin-console reorganization and routine self-hosted release-channel updates.
The product is converging on agent-built, React-based apps as its forward direction, treating the visual builder as one entry point among several. Self-hosted customers keep getting parallel Edge and Stable releases, signaling Retool is keeping its enterprise base in step with the builder rewrite.
Expect the new app builder to absorb more of the legacy builder's capabilities and MCP-driven app generation to deepen, with admin tooling continuing to consolidate.
Ably's realtime SDKs march on, with an AI transport line taking shape.
Ably is in a steady client-library cadence — JS point releases, a Chat SDK update, a new Dart SDK, and dashboard visibility for LiveObjects. The thread worth watching is the AI Transport SDK, now at 0.2.0 with clearer session/run APIs and human-in-the-loop handoff.
Core pub/sub realtime keeps broadening across languages (Dart) and surfaces (LiveObjects), while Ably builds a dedicated transport layer for AI agents. The agentic line is still early but consistently advancing.
Expect the AI Transport SDK to keep maturing toward a stable release and more language coverage across the SDK family; the entries don't indicate timing for a 1.0 of the AI transport.
