What is Auth0?

Auth0 hands tenants a throttle on their own noisy apps

Custom Rate Limits enter Early Access, letting a tenant cap requests per second for individual clients or whole classes of them — third-party, CIMD — so one application cannot exhaust the tenant's Authentication API rate limit entitlement. Policies are configured through an API and can be rolled out in notify-only mode before they start blocking. It arrives in a dense window that also brought Flexible Password Policy to GA and Custom Prompts parity across social and enterprise connections.

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.

Auth0 hands tenants a throttle on their own noisy apps

◆ Current state

Custom Rate Limits enter Early Access, letting a tenant cap requests per second for individual clients or whole classes of them — third-party, CIMD — so one application cannot exhaust the tenant's Authentication API rate limit entitlement. Policies are configured through an API and can be rolled out in notify-only mode before they start blocking. It arrives in a dense window that also brought Flexible Password Policy to GA and Custom Prompts parity across social and enterprise connections.

◆ Where it's heading

Two threads dominate. One is agent and delegation infrastructure — Agents as Principal, Token Vault Privileged Worker, Custom Token Exchange session delegation — all still in Early Access. The other is tenant self-service: rate limits, blocklists, organization search and roles, global search. Auth0 is systematically converting things that required support intervention into API-configurable policy.

◆ Prediction

The Early Access items now stacking up, particularly the agent-identity pieces, are the obvious GA candidates next, following the Flexible Password Policy path from Early Access to general availability.

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.
