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 Userback?
Userback's Sites turn out to be a multi-site workspace, and the first follow-up targets agencies.
Userback has spent 2026 widening where feedback comes from (mobile SDK, Slack, mobile surveys) and adding an AI layer on top (Insights themes, video transcription, AI Context Search). The October 28 follow-up finally shows what Sites is: a per-site container with its own Site Key, settings, widget and feedback list. The new tools are prefixed readable feedback IDs that pass through to Jira, copying widget settings between Sites, open-feedback counts on the Sites page, and survey targeting by query string and hash.
SigNoz vs Userback: editorial side-by-side
SigNoz
5.0INFRA · APIS
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.
Userback
5.0INFRA · APIS
Userback's Sites turn out to be a multi-site workspace, and the first follow-up targets agencies.
◆ Current state
Userback has spent 2026 widening where feedback comes from (mobile SDK, Slack, mobile surveys) and adding an AI layer on top (Insights themes, video transcription, AI Context Search). The October 28 follow-up finally shows what Sites is: a per-site container with its own Site Key, settings, widget and feedback list. The new tools are prefixed readable feedback IDs that pass through to Jira, copying widget settings between Sites, open-feedback counts on the Sites page, and survey targeting by query string and hash.
◆ Where it's heading
Sites moves Userback toward running many properties from one account. Copying widget settings and sorting Sites by open feedback are built for agencies with a Site per client. The readable IDs that travel into Jira and other integrations show the same push seen in the 'Sent to Integrations' filter: making Userback the traceable start of a ticket, not a separate inbox.
◆ Prediction
Expect more cross-Site tooling, such as copying integrations or templates between Sites, since the October 28 notes say integrations still have to be set up per Site.
