What is Auth0?
Auth0 is building the identity layer for AI agents acting on behalf of users
Auth0's releases cluster around two themes: standards-based enterprise security (DPoP, federated logout, tenant ACLs) and identity primitives for agentic and machine-to-machine flows (Token Vault org scoping, Custom Token Exchange, scope customization). The most consequential recent work lets a service or AI agent act for a user while preserving both identities in a verifiable, auditable way. The cadence is steady and feature-dense, weighted toward Enterprise and B2B SaaS builders.
What is Merge?
Merge raises the floor on integration fidelity — object URLs and per-tenant identity, week after week.
Merge ships a weekly changelog rhythm across Accounting, ATS, CRM, File Storage, and Chat. Recent weeks emphasize two motifs: making cross-system object URLs first-class in unified responses (Xero, NetSuite, Oracle Fusion) and exposing per-tenant identification on linked accounts so B2B SaaS customers can disambiguate multi-org installs (HubSpot, Dynamics, Zoho, Pipedrive). The cadence is dense and field-level, weighted toward mapping enhancements, webhook fidelity, and edge-case fixes per integration.

Auth0 is building the identity layer for AI agents acting on behalf of users
◆ Current state
Auth0's releases cluster around two themes: standards-based enterprise security (DPoP, federated logout, tenant ACLs) and identity primitives for agentic and machine-to-machine flows (Token Vault org scoping, Custom Token Exchange, scope customization). The most consequential recent work lets a service or AI agent act for a user while preserving both identities in a verifiable, auditable way. The cadence is steady and feature-dense, weighted toward Enterprise and B2B SaaS builders.
◆ Where it's heading
Auth0 is positioning itself as the delegation and token-exchange layer for agentic AI, leaning on open standards (RFC 8693, FAPI2, IPSIE) so enterprises can adopt agents without losing audit trails. Token Vault org support and delegated authorization together let multi-tenant SaaS embed agents that hold and exchange third-party tokens per organization. Expect continued hardening of these primitives from Early Access toward GA.
◆ Prediction
Next likely moves are GA promotions of the delegated-authorization and scope-customization features now in Early Access, plus more agent-oriented tooling around Token Vault and Connected Accounts.

Merge raises the floor on integration fidelity — object URLs and per-tenant identity, week after week.
◆ Current state
Merge ships a weekly changelog rhythm across Accounting, ATS, CRM, File Storage, and Chat. Recent weeks emphasize two motifs: making cross-system object URLs first-class in unified responses (Xero, NetSuite, Oracle Fusion) and exposing per-tenant identification on linked accounts so B2B SaaS customers can disambiguate multi-org installs (HubSpot, Dynamics, Zoho, Pipedrive). The cadence is dense and field-level, weighted toward mapping enhancements, webhook fidelity, and edge-case fixes per integration.
◆ Where it's heading
Two clear pulls. First, raising the floor on data fidelity — every endpoint should surface an object URL, every linked account should expose tenant identity. Second, expanding Accounting Unified API coverage in both directions, with Oracle Fusion Cloud ERP joining in beta alongside continued NetSuite and QuickBooks polish. Merge is treating the unified API less as a thin translation layer and more as a normalization product where the parity bar keeps moving up.
◆ Prediction
Expect Oracle Fusion Cloud ERP to graduate from beta with broader endpoint coverage, more tenant-identification rollouts to less-mature CRM connectors, and continued webhook-parity work for write operations across Accounting providers.
