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 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.

Auth0

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.
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.
