Auth0 vs Ably
Side-by-side trajectory, velocity, and editorial themes.
Auth0 is re-tooling identity for AI agents and B2B multi-tenancy
Auth0 is shipping a dense stream of GA releases aimed squarely at two buyers: enterprises running B2B SaaS on Organizations, and developers wiring AI agents and partner services into their APIs. Recent work spans machine-to-machine access for third-party apps, organization-scoped Token Vault, delegated authorization, SCIM group provisioning, and passkey refinements. The dashboard itself is getting a navigation and search overhaul in beta.
The center of gravity is moving from human login toward non-human and delegated identity. M2M for third-party apps, RFC 8693 delegated authorization with actor claims, and DPoP sender constraining all point at agentic and service-to-service flows where no user is in the loop. B2B delegated administration (self-service SCIM, group-to-role mapping) is the parallel track, pushing configuration work out to enterprise customers.
Expect the Early Access agentic pieces — custom token exchange delegated authorization and scope-customization Actions — to march to GA next, alongside continued dashboard consolidation as the IA refresh exits beta.
Ably is rebuilding its realtime stack around AI agents: transport SDK and agent-native CLI
Ably is repositioning its realtime messaging infrastructure around AI agents. The clearest evidence is a dedicated AI Transport SDK, now with a session/run model, conversation branching, and human-in-the-loop handoff, plus a CLI rebuilt to be agent-operable that installs Agent Skills into Claude, Cursor, and Windsurf and emits structured JSON for self-healing automation. Underneath, the core Pub/Sub and Chat SDKs keep maturing and platform reach widens with a new Dart/Flutter SDK.
The trajectory is realtime-as-agent-infrastructure: the AI Transport SDK is iterating fast toward production agent apps with branching, suspend/resume, and tool-calling, while the tooling is built so AI coding agents, not just humans, can drive Ably. The conventional SDK and CLI work continues in parallel, but the directional energy is clearly aimed at the agent stack.
Expect the AI Transport SDK to keep adding agent-conversation primitives on its march to 1.0, and the Dart SDK to fill toward parity with the JS line.
