What is Auth0?
Auth0 hardens enterprise IAM: federated sessions, token governance, and automated provisioning.
Auth0's recent releases cluster around enterprise identity correctness rather than new consumer-facing auth. The work spans federated session lifecycle (IPSIE session_expiry enforcement for Okta and OIDC connections), refresh-token governance, and B2B Organizations, where third-party app access is now GA with per-organization control. Dashboard search and Google One Tap round out smaller admin- and login-surface conveniences.
What is Merge?
A unified-API company is quietly rebuilding itself as AI-agent infrastructure
Merge ships dense weekly changelogs across three surfaces: the original Unified API (accounting, HRIS, ATS, CRM, file storage, ticketing), Agent Handler (governed tools and connectors for AI agents), and Merge Gateway (a model-routing and LLM-security layer). The Unified API work is steady maintenance — mapping enhancements, sync performance, and edge-case handling across dozens of integrations. The energy and net-new capability sit in Agent Handler and Gateway.

Auth0
6.3INFRA · APISDEVOPS
Auth0 hardens enterprise IAM: federated sessions, token governance, and automated provisioning.
◆ Current state
Auth0's recent releases cluster around enterprise identity correctness rather than new consumer-facing auth. The work spans federated session lifecycle (IPSIE session_expiry enforcement for Okta and OIDC connections), refresh-token governance, and B2B Organizations, where third-party app access is now GA with per-organization control. Dashboard search and Google One Tap round out smaller admin- and login-surface conveniences.
◆ Where it's heading
The through-line is Auth0 positioning as the enterprise IAM control plane, not just a login box: closing federation gaps, adding token-level governance, and this cycle extending Event Streams into outbound SCIM provisioning. That last move pushes Auth0 into automated downstream lifecycle management, territory historically owned by workforce-IAM incumbents like Okta. Standards alignment (the IPSIE profile) and Event Streams as an integration backbone are becoming the spine of the roadmap.
◆ Prediction
Expect more Event Streams Action templates and additional IPSIE-profile coverage as Auth0 builds out provisioning and federated-session parity with incumbent workforce-IAM vendors.

A unified-API company is quietly rebuilding itself as AI-agent infrastructure
◆ Current state
Merge ships dense weekly changelogs across three surfaces: the original Unified API (accounting, HRIS, ATS, CRM, file storage, ticketing), Agent Handler (governed tools and connectors for AI agents), and Merge Gateway (a model-routing and LLM-security layer). The Unified API work is steady maintenance — mapping enhancements, sync performance, and edge-case handling across dozens of integrations. The energy and net-new capability sit in Agent Handler and Gateway.
◆ Where it's heading
Merge is levering its integration catalog into an agent-tooling and model-routing play. Gateway keeps adding frontier models, custom routing, and enterprise controls (RBAC, audit, prompt-injection protection, DLP), while Agent Handler expands connectors and observability. The through-line: the same normalized-integration muscle that powered unified data access is now being pointed at giving AI agents governed, routable access to tools and models. Unified API is the stable base; the growth vector is agent infrastructure.
◆ Prediction
Expect Gateway to keep absorbing new frontier models and routing controls on a weekly cadence, and Agent Handler to keep converting existing Unified API integrations into agent-callable connectors.
