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.

What is werf?

werf v3.12.1 is tagged on every channel including stable and rock-solid, not just dev.

werf v3.12.1 fixes deploys that use saved plans containing a blind apply, and it is the first v3 release in the feed tagged on the alpha, beta, ea, stable and rock-solid channels rather than dev. The v2 line continues in parallel (v2.84.0 alpha) with the same build features.

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.

5.0

werf v3.12.1 is tagged on every channel including stable and rock-solid, not just dev.

◆ Current state

werf v3.12.1 fixes deploys that use saved plans containing a blind apply, and it is the first v3 release in the feed tagged on the alpha, beta, ea, stable and rock-solid channels rather than dev. The v2 line continues in parallel (v2.84.0 alpha) with the same build features.

◆ Where it's heading

Through October the v3 line had shipped as dev releases that mirrored v2 features while adding its own Helm-compatible release storage. Putting v3.12.1 on all channels suggests v3 is now the main line and v2 is moving to maintenance, though the entry itself doesn't say so.

◆ Prediction

Expect v3 releases to keep landing on stable channels and v2 to receive fewer feature releases; a migration note for v2 users would confirm the shift.
