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 Supabase?

Supabase is closing its most-exploited default: tables stop being public unless you say so.

The last month is dominated by tightening defaults rather than adding surface. New tables in the public schema will no longer be auto-exposed to the Data and GraphQL APIs, pg_graphql stops being enabled by default, and the OAuth token endpoint is being corrected to return 200 per OAuth 2.1. Alongside that, custom OAuth/OIDC providers landed for Auth and an RLS Tester entered preview.

SigNoz vs Supabase: editorial side-by-side

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.

Supabase is closing its most-exploited default: tables stop being public unless you say so.

◆ Current state

The last month is dominated by tightening defaults rather than adding surface. New tables in the public schema will no longer be auto-exposed to the Data and GraphQL APIs, pg_graphql stops being enabled by default, and the OAuth token endpoint is being corrected to return 200 per OAuth 2.1. Alongside that, custom OAuth/OIDC providers landed for Auth and an RLS Tester entered preview.

◆ Where it's heading

Supabase is paying down the security cost of its own convenience. Auto-exposing every public-schema table made the product fast to start with and easy to misconfigure; the fix is explicit Postgres grants, staged over six months from new projects in April to all existing projects on October 30. The RLS Tester is the same theme from the other side — the auto-exposure default only worked if row-level security was correct, and until now there was no way to check.

◆ Prediction

Expect the remaining rollout dates to hold and more of the developer experience to be rebuilt around explicit grants, with the RLS Tester graduating from preview as it becomes the tool people need to verify the new model. The October cutover for existing projects is the moment where this stops being an announcement and starts breaking things.
