What is Kestra?

Kestra's design system adds richer filters while 2.1.0 sits at its first release candidate.

Kestra's feed is quiet and internal: design-system v0.6.0 adds search, number filters and value counts to its KsFilter component, after v0.5.0 removed Bootstrap from the UI core. Kestra 2.1.0-rc1 was tagged on 10-20 with no release notes.

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.

Kestra vs SigNoz: editorial side-by-side

K
Kestra
INFRA · APIS
5.0

Kestra's design system adds richer filters while 2.1.0 sits at its first release candidate.

◆ Current state

Kestra's feed is quiet and internal: design-system v0.6.0 adds search, number filters and value counts to its KsFilter component, after v0.5.0 removed Bootstrap from the UI core. Kestra 2.1.0-rc1 was tagged on 10-20 with no release notes.

◆ Where it's heading

The visible work is a frontend refactor onto Kestra's own design system, which should show up as filter and table improvements in the 2.1 UI. The feed has no notes on 2.1's orchestration features.

◆ Prediction

Expect 2.1.0 to ship with new filtering in the UI; the entries don't say what else it contains.

SigNoz

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.
