What is Knock?

Knock is pushing its agent into more surfaces while making notification config a no-engineering job.

Knock, a notifications-infrastructure platform, is building two parallel tracks: an agent that can create and manage messaging resources from inside tools like Slack, and a steady stream of dashboard-driven features that move configuration work off engineers. Recent releases span a hosted preference center, dynamic audiences, new data sources, and template tooling. The product is widening from a developer API toward a self-serve control surface.

What is Retool?

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.

Knock is pushing its agent into more surfaces while making notification config a no-engineering job.

◆ Current state

Knock, a notifications-infrastructure platform, is building two parallel tracks: an agent that can create and manage messaging resources from inside tools like Slack, and a steady stream of dashboard-driven features that move configuration work off engineers. Recent releases span a hosted preference center, dynamic audiences, new data sources, and template tooling. The product is widening from a developer API toward a self-serve control surface.

◆ Where it's heading

The direction is toward less engineering involvement per change — agents, dashboard-built audiences, and hosted end-user UI all shorten the code path. Integrations like the Shopify data source extend Knock's triggers into commerce events, broadening what notifications can be driven by. The agent and the dashboard keep absorbing tasks that previously required custom code.

◆ Prediction

The next moves likely deepen the agent (more surfaces or skills) and add further data sources, continuing the shift toward dashboard- and agent-driven configuration over hand-written integration code.

Retool fills in its AI-native React app builder

◆ Current state

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.

◆ Where it's heading

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.

◆ Prediction

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.
