What is Novu?
Novu makes its workflows controllable by AI agents and by code, not just dashboards.
Novu's recent arc moves notification workflows out of a single editing surface. November introduced Contexts for multi-tenant scoping, January shipped Subscriptions plus a React Subscription component, April let any step run in Custom Code mode with CLI publishing, and the Novu MCP Server went GA in late April with 20+ tools covering subscribers, triggering, cancellation, and integrations. Slack chat is in private beta.
What is Tailscale?
Tailscale is turning the tailnet itself into something a script provisions and pages through.
Two threads run in this window. The client and operator releases are maintenance-grade — a Funnel regression fix, library-only container updates, Kubernetes operator work on PeerRelays, workload identity federation and IPv6 egress. The more consequential thread is the tailnet management API: creation landed in alpha at the end of July, and the list endpoint has now been paginated, with a hard 100-result default for organizations holding more.

Novu
2.1INFRA · APIS
Novu makes its workflows controllable by AI agents and by code, not just dashboards.
◆ Current state
Novu's recent arc moves notification workflows out of a single editing surface. November introduced Contexts for multi-tenant scoping, January shipped Subscriptions plus a React Subscription component, April let any step run in Custom Code mode with CLI publishing, and the Novu MCP Server went GA in late April with 20+ tools covering subscribers, triggering, cancellation, and integrations. Slack chat is in private beta.
◆ Where it's heading
Novu is positioning as a notification platform an AI agent can drive end-to-end and a developer can wire from code, with the dashboard becoming optional. The MCP Server GA codifies that pitch publicly. Expect more tools exposed over MCP and continued depth on tenant scoping, since multi-tenant SaaS is the main buyer.
◆ Prediction
The next directional move likely formalizes agent-built workflows as first-class artifacts with versioning and approval, so AI-authored notifications can survive review. Slack and other chat integrations should leave beta and join the standard provider list.
Tailscale
6.3INFRA · APIS
Tailscale is turning the tailnet itself into something a script provisions and pages through.
◆ Current state
Two threads run in this window. The client and operator releases are maintenance-grade — a Funnel regression fix, library-only container updates, Kubernetes operator work on PeerRelays, workload identity federation and IPv6 egress. The more consequential thread is the tailnet management API: creation landed in alpha at the end of July, and the list endpoint has now been paginated, with a hard 100-result default for organizations holding more.
◆ Where it's heading
Tailscale has spent this period on two different customers at once. The operator work serves platform teams running Tailscale inside Kubernetes, where the gaps being closed are reconciliation loops, stale DNS ConfigMaps and cert-renewal backoff. The tailnet API work serves a different shape entirely: organizations holding enough tailnets that a hundred is a page boundary, which only happens when tailnets are allocated per customer or per environment rather than per company. The second thread is the one that changes what Tailscale is for.
◆ Prediction
Pagination on list implies the creation API is being used at volume, so expect the alpha to gain the management operations a fleet needs — policy templating or bulk configuration across tailnets. The client release line looks settled on 1.102.x maintenance in the near term.
