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 Ory Hydra?

Hydra's 2.2 candidates rebuilt the OAuth2 flow store, then reached for verifiable credentials

Ory Hydra is a self-hosted OAuth2 and OpenID Connect server. Its visible release record is the v2.2.0 candidate series from 2023, which did two substantial things: rc.2 moved authorization-code flow state out of the database and into AEAD-encrypted cookies and request parameters, a change shipped with an explicit breaking-change notice; rc.3 then added initial OIDC verifiable-credential issuance and wired logout propagation into Ory Kratos. The feed stops at a v2.2.0-pre.1 tag in February 2024.

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.

Hydra's 2.2 candidates rebuilt the OAuth2 flow store, then reached for verifiable credentials

◆ Current state

Ory Hydra is a self-hosted OAuth2 and OpenID Connect server. Its visible release record is the v2.2.0 candidate series from 2023, which did two substantial things: rc.2 moved authorization-code flow state out of the database and into AEAD-encrypted cookies and request parameters, a change shipped with an explicit breaking-change notice; rc.3 then added initial OIDC verifiable-credential issuance and wired logout propagation into Ory Kratos. The feed stops at a v2.2.0-pre.1 tag in February 2024.

◆ Where it's heading

The through-line is reducing per-request database work in the hot authorization path — first by relocating flow state into encrypted client-side material, then by parallelizing JSON web key set generation and adding scope-claim strategies. Running underneath is tighter coupling to the rest of the Ory stack: the Kratos admin URL config and session-termination hook make Hydra less of a standalone component and more of one piece of an integrated identity suite. The verifiable-credentials work is the one thread pointing somewhere genuinely new, and it shipped against a draft specification.

◆ Prediction

The candidate series points toward a v2.2.0 general release consolidating the AEAD flow change and the credential-issuance work. The feed's silence after February 2024 gives no basis for judging when, or whether the draft-stage VC support advanced.
