What is authentik?

authentik patches 2026.8 and 2026.5 together, with cert updates after the eMudhra CA compromise.

authentik is in maintenance mode on its release branches. 2026.8.5 fixes an endpoints MultipleObjectsReturned error, skips members already in Microsoft Entra groups during sync, stops the Agents tab flashing for unlicensed users, and bumps certificate dependencies after the eMudhra CA compromise. 2026.5.8 backports a longer list, including a consent re-grant error, websocket header handling and pool credential refresh.

What is SigNoz?

SigNoz makes LLM traces readable with a conversation-style Thread view.

SigNoz now renders AI traces as a conversation: each LLM call's input and output messages, reasoning, tool calls and results laid out in sequence, instead of raw JSON in span details. It reads OTel gen_ai attributes plus formats from OpenAI, Anthropic, Gemini, LangChain, Vercel AI SDK, LiteLLM, OpenInference and others. The v1 alert rule API is still set for removal on November 11.

authentik vs SigNoz: editorial side-by-side

A
authentik
INFRA · APIS
5.0

authentik patches 2026.8 and 2026.5 together, with cert updates after the eMudhra CA compromise.

◆ Current state

authentik is in maintenance mode on its release branches. 2026.8.5 fixes an endpoints MultipleObjectsReturned error, skips members already in Microsoft Entra groups during sync, stops the Agents tab flashing for unlicensed users, and bumps certificate dependencies after the eMudhra CA compromise. 2026.5.8 backports a longer list, including a consent re-grant error, websocket header handling and pool credential refresh.

◆ Where it's heading

Since the 2026.8.0 Agent and Actors release, every entry has been a patch on 2026.8 or an older branch, and the team keeps three branches supported. The fixes are concentrated in sync providers, the proxy outpost and the new Agents UI.

◆ Prediction

Expect further 2026.8.x patches and a 2026.11 release candidate; the entries don't yet show what the next feature release contains.

SigNoz
INFRA · APIS
5.0

SigNoz makes LLM traces readable with a conversation-style Thread view.

◆ Current state

SigNoz now renders AI traces as a conversation: each LLM call's input and output messages, reasoning, tool calls and results laid out in sequence, instead of raw JSON in span details. It reads OTel gen_ai attributes plus formats from OpenAI, Anthropic, Gemini, LangChain, Vercel AI SDK, LiteLLM, OpenInference and others. The v1 alert rule API is still set for removal on November 11.

◆ Where it's heading

SigNoz is moving into LLM observability from both sides: August's plugin put it inside AI coding agents, and the Thread view now makes it a place to debug AI apps. Underneath, the alerting API keeps migrating on fixed, repeatedly announced dates. Alert channels into incident tools fill out the operational side.

◆ Prediction

Expect more AI-specific views on top of the Thread view, such as token or cost breakdowns per conversation, and the v1 rules removal to ship on November 11 as announced.
