What is Keycloak?

Keycloak patches its 26.4 and 26.6 lines in lockstep; the tags carry no notes.

The tracked Keycloak entries are version-set commits for two supported lines, 26.4.x and 26.6.x, cut on the same day in August and again in September. The release feed carries only the version bump, so the fixes inside each patch aren't visible here.

What is Tolgee?

Tolgee adds OAuth 2.1 for MCP clients, making agent access a first-class login path.

Tolgee ships near-daily releases, mostly backend and editor patches. October 9 brought four minors: community suggestions from the in-context dialog, public-read S3 uploads for content delivery, a G2 review prompt for self-hosted admins, and OAuth 2.1 for MCP clients with audience binding, client metadata documents, and SSRF hardening.

Keycloak vs Tolgee: editorial side-by-side

K
Keycloak
INFRA · APIS
0.0

Keycloak patches its 26.4 and 26.6 lines in lockstep; the tags carry no notes.

◆ Current state

The tracked Keycloak entries are version-set commits for two supported lines, 26.4.x and 26.6.x, cut on the same day in August and again in September. The release feed carries only the version bump, so the fixes inside each patch aren't visible here.

◆ Where it's heading

Keycloak is maintaining two release lines in parallel with roughly monthly patch drops. Without notes in the feed, the entries show cadence and support policy, not product direction.

◆ Prediction

Another paired 26.4/26.6 patch release around early October fits the monthly pattern; the entries don't show what features are in development.

5.0

Tolgee adds OAuth 2.1 for MCP clients, making agent access a first-class login path.

◆ Current state

Tolgee ships near-daily releases, mostly backend and editor patches. October 9 brought four minors: community suggestions from the in-context dialog, public-read S3 uploads for content delivery, a G2 review prompt for self-hosted admins, and OAuth 2.1 for MCP clients with audience binding, client metadata documents, and SSRF hardening.

◆ Where it's heading

Two threads now run alongside the maintenance stream. One is growth: community contribution, Figma plugin promotion, plan-limit banners, and review solicitation. The other is access for AI agents: the MCP OAuth work, coordinated with the CLI, treats agent clients as authenticated users rather than holders of API keys.

◆ Prediction

Expect follow-up patches to the MCP auth flow and the CLI that consumes it, plus fixes for the community suggestion flow. The entries do not show whether MCP access will expand to new tools or stay limited to authentication.
