LookMeNot by Sunil Kumar Pradhan

LookMeNot helps developers inspect Langfuse observability traces without reading nested JSON by hand.

Open a Langfuse trace and LookMeNot appears as a left-side conversation pane. It detects trace payloads from the page, extracts messages, tool calls, tool results, thinking blocks, and observation data, then renders them in chronological order.

Features :-

• Conversation-style trace reading
• Tool call and tool result cards
• Thinking block visibility controls
• Search across messages, tool names, and tool inputs
• Jump-to-entry navigation
• Expand/collapse controls for long content
• Manual JSON upload and paste fallback
• Toolbar-button support for self-hosted Langfuse instances

Trace data is processed locally in Firefox. The extension does not send trace content to LookMeNot servers, analytics providers, or third parties.
