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 Tailscale?

Tailscale turns the tailnet into an identity layer for AI agents via Aperture

Tailscale's core remains its WireGuard-based, identity-aware networking, carried by steady point releases (v1.98.x), a maturing Kubernetes Operator, and a Terraform provider. The visible energy, though, is in Aperture, an alpha product line that layers agent and LLM tooling on top of the tailnet's identity fabric.

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.

Tailscale turns the tailnet into an identity layer for AI agents via Aperture

◆ Current state

Tailscale's core remains its WireGuard-based, identity-aware networking, carried by steady point releases (v1.98.x), a maturing Kubernetes Operator, and a Terraform provider. The visible energy, though, is in Aperture, an alpha product line that layers agent and LLM tooling on top of the tailnet's identity fabric.

◆ Where it's heading

Tailscale is extending its identity-and-access model from connecting devices to governing AI agents. Aperture, now spanning a CLI, a chat interface, connectors, and sandboxes, reuses tailnet access controls as the policy layer for agent access to data and compute. The mature networking products are in maintenance and hardening mode while Aperture defines the new capability surface.

◆ Prediction

Expect Aperture to keep expanding, with more connectors and broader agent and sandbox support, and to move from alpha toward general availability, with tailnet ACLs positioned as the single access-control story for both devices and agents.
