Jsonl Session Log Parsing With Per Turn Reconstruction

via “jsonl transcript processing and session analysis metrics”

🚀 Beautiful highly customizable statusline for Claude Code CLI with powerline support, themes, and more.

Unique: Implements streaming JSONL parsing to avoid loading entire transcript files into memory, enabling analysis of large conversation histories. Supports custom metric extraction via widget configuration, allowing users to define which transcript fields to aggregate without code changes.

vs others: More efficient than loading entire transcripts into memory because it uses line-by-line streaming; more flexible than hardcoded metrics because users can define custom aggregations.

via “jsonl session log parsing with per-turn reconstruction”

The missing DevTools for Claude Code — inspect session logs, tool calls, token usage, subagents, and context window in a visual UI. Free, open source.

Unique: Implements streaming JSONL parsing with multi-level caching (file-level and turn-level) to reconstruct per-turn context windows without requiring full session file loads, combined with path encoding scheme (Project IDs) to handle complex project hierarchies and remote SSH paths uniformly

vs others: Provides deeper execution visibility than Claude Code's native --verbose output by structuring raw logs into queryable turn-by-turn traces, while avoiding the terminal flooding and raw JSON noise of verbose mode
