What is Quay?

Quay keeps both enterprise branches on a monthly CVE-patch metronome — and nothing else.

All ten releases in this window are security maintenance: dependency bumps for CVEs, SSRF hardening in mirroring and proxy cache, and a robot-token visibility fix for readonly superusers. The October pair (3.12.23 and 3.10.27) patches the same four CVEs — immutable, qs, lxml, WebOb — plus a compression bump. Neither line has shipped a user-facing feature in four months.

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.

Quay vs SigNoz: editorial side-by-side

Q
Quay
INFRA · APIS
5.0

Quay keeps both enterprise branches on a monthly CVE-patch metronome — and nothing else.

◆ Current state

All ten releases in this window are security maintenance: dependency bumps for CVEs, SSRF hardening in mirroring and proxy cache, and a robot-token visibility fix for readonly superusers. The October pair (3.12.23 and 3.10.27) patches the same four CVEs — immutable, qs, lxml, WebOb — plus a compression bump. Neither line has shipped a user-facing feature in four months.

◆ Where it's heading

The 3.10 and 3.12 lines move in lockstep, typically within hours to days of each other, on a roughly monthly cadence. New Containerfile.art files for ART/Konflux builds point to packaging work on Red Hat's build pipeline rather than product changes. Feature work, if any, is not surfacing in these maintenance branches.

◆ Prediction

Expect the next 3.12.x/3.10.x pair in roughly a month with another batch of CVE bumps. The entries give no signal of when or whether new capabilities will land on these lines.

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.
