What is FusionAuth?

FusionAuth adds RFC 8707 resource-scoped tokens while most recent changelogs surface only upgrade boilerplate.

FusionAuth's changelog data is thinly populated — most entries show only the standard upgrade recommendation with no detailed content. The substantive releases are 1.67.0 (RFC 8707 resource indicators for OAuth tokens, enabling per-resource audience scoping in the `aud` claim) and 1.66.0 (webhook endpoint security hardening requiring global API keys, a breaking change). FusionAuth is an open-source, self-hosted identity platform in consistent quarterly release cadence.

What is Speakeasy?

Speakeasy becomes the enterprise control plane for MCP server access and AI tool governance.

Speakeasy has pivoted from an SDK/API generation tool into a full governance platform for Model Context Protocol infrastructure. In the past week, the product shipped per-server access control pages, per-tool permission granularity, killswitch management, credential verification for remote sessions, and a breaking refactor to risk policy scoping. The pace of feature delivery across v1.21–v1.25 is high, and the product surface has grown substantially: shadow AI detection, OTLP risk export, catalog management, and editable gateway instructions are all now part of the same control plane.

FusionAuth vs Speakeasy: editorial side-by-side

F2.5

FusionAuth adds RFC 8707 resource-scoped tokens while most recent changelogs surface only upgrade boilerplate.

◆ Current state

FusionAuth's changelog data is thinly populated — most entries show only the standard upgrade recommendation with no detailed content. The substantive releases are 1.67.0 (RFC 8707 resource indicators for OAuth tokens, enabling per-resource audience scoping in the `aud` claim) and 1.66.0 (webhook endpoint security hardening requiring global API keys, a breaking change). FusionAuth is an open-source, self-hosted identity platform in consistent quarterly release cadence.

◆ Where it's heading

RFC 8707 implementation and the webhook endpoint security hardening both point toward a standards-compliance and security posture focus rather than surface feature expansion. The breaking change in 1.66.0 prioritizing security correctness over backward compatibility signals a product that prioritizes operational security for self-hosters. Version naming with code names (Intelligent Kamfa, Tenant Manager SSO Tasmanian Mountain Skink) is purely cosmetic.

◆ Prediction

Standards compliance is the clearest trajectory — RFC implementations tend to cluster. FAPI 2.0 or OAuth 2.0 Rich Authorization Requests are likely candidates given the resource-scoping direction in RFC 8707.

10.0

Speakeasy becomes the enterprise control plane for MCP server access and AI tool governance.

◆ Current state

Speakeasy has pivoted from an SDK/API generation tool into a full governance platform for Model Context Protocol infrastructure. In the past week, the product shipped per-server access control pages, per-tool permission granularity, killswitch management, credential verification for remote sessions, and a breaking refactor to risk policy scoping. The pace of feature delivery across v1.21–v1.25 is high, and the product surface has grown substantially: shadow AI detection, OTLP risk export, catalog management, and editable gateway instructions are all now part of the same control plane.

◆ Where it's heading

Every release deepens the enterprise governance story: finer-grained access controls, trusted issuer chains for enterprise IdP integration, and precise billing instrumentation from exact meter readings. The direction is clear—Speakeasy is positioning itself as the security and compliance layer for organizations deploying AI agents at scale. The API-breaking risk policy refactor signals the team is willing to clean house to reach a coherent model rather than accumulate overlapping scope mechanisms.

◆ Prediction

The next move is likely deeper audit and compliance tooling—possibly signed event logs, per-user MCP usage reports meeting enterprise security requirements, or wider IdP federation support beyond the current OIDC/RFC 8414 implementation.
