recensa

Every Claude Code session you run is written to disk as raw JSONL under ~/.claude/projects/ — the full conversation, every tool call, the model's thinking, every subagent it spawned. Then it just sits there, unreadable. Want to know how you fixed that bug last month? What that 40-minute agent run actually changed? Which of your prompts sent it down a dead end? Good luck grepping.

Recensa indexes those transcripts into a local SQLite database and serves a three-pane reader at http://localhost:7788. Reading never modifies your transcripts, and the index is a disposable cache you can rebuild at any time.

Quick start

You need Docker (Docker Desktop on Windows/macOS, Docker Engine on Linux) and a ~/.claude directory with some sessions in it.

Try it — run the prebuilt image straight from Docker Hub:

# macOS / Linux
docker run -d --name recensa -p 127.0.0.1:7788:7788 \
  -v "$HOME/.claude:/data/claude:z" \
  -v recensa-data:/app/backend/data \
  -e RECENSA_PROJECTS_DIR=/data/claude/projects \
  s40911120/recensa

On Linux, ~/.claude/projects is created owner-only (700/600) by the host CLI, so the container needs a matching uid/gid to read it — it detects this on its own from the mount, no flags required. The trailing :z relabels the mount for SELinux-enforcing hosts (RHEL/Fedora/CentOS, Podman); it's a no-op everywhere else, including macOS and Windows Docker Desktop, so it's safe to always include. Override the detected uid/gid with -e PUID=... -e PGID=... if the mount's owner isn't the account you want.

# Windows — use PowerShell, not Git Bash (MSYS rewrites the /data/... paths)
docker run -d --name recensa -p 127.0.0.1:7788:7788 `
  -v "$env:USERPROFILE\.claude:/data/claude" `
  -v recensa-data:/app/backend/data `
  -e RECENSA_PROJECTS_DIR=/data/claude/projects `
  s40911120/recensa

Or run it from source with Compose:

git clone https://github.com/S40911120/recensa.git && cd recensa
cp .env.example .env             # set CLAUDE_HOME to your .claude path
docker compose up -d --build

Then open http://localhost:7788. The first index runs in a background worker and can take minutes to tens of minutes depending on how many sessions you have — the UI is usable while it runs, and progress shows in a floating pill in the corner.

A tour

Search all of it, not the last five. Claude Code's resume picker shows a handful of recent sessions. Recensa's full-text search (SQLite FTS5, CJK-aware) covers every session you have ever run — "how did I fix that S3 retry bug?" is one query away.

Follow the conversation, not the noise. One session can hold thousands of tool calls. God-view folds tools, thinking, and system noise into landmark rows you can expand on demand. Async tool results are paired back to their call with a shared colored rail, so a tool_result landing twelve messages later still reads as one step.

Or cut the noise down two ways. The Main toggle (top right) folds every tool call and thinking block away, leaving only your prompts and the model's replies. Focus mode (the tab at the bottom) hides the app chrome itself — panels, header, breadcrumb — for full-width, distraction-free reading. Esc exits.

See exactly what changed. Every Edit in a session renders as a real diff — before in red, after in green, per-file, with timestamps. Audit an agent's changes without leaving the reader.

Know what a session cost. Per-session statistics break down tool usage, files created / edited / deleted, model mix, token flow, and an estimated dollar cost.

Audit multi-agent runs. When a session spawns subagents or teammates, Recensa rebuilds the roster from the transcripts: every agent with its type, message count, and model in the info panel, a crosshair that jumps to the exact call site where it was spawned, and an "Open subagent transcript" deep-link into the agent's own conversation — and back.

Navigate compaction like it never happened. When Claude Code compacts a long session, the pre-compaction text is gone from the working context — but not from the transcript chain. Recensa marks every compaction point in the stream, lists them in a Compaction History panel so you can jump straight to any boundary, tracks your read position within the current compaction segment, and can reconstruct the full pre-compaction conversation, merged across the fork/resume chain, as a read-only view.

Keep your reading state. Pin, tag, rename, and annotate sessions. Your curation lives in its own database (flags.db) that index rebuilds never touch. Live sessions update in real time over WebSocket while Claude Code is still writing them.

Reads fine on a phone. The layout is responsive: on narrow screens the session list and the info panel become swipe-in drawers around the conversation, so checking what an agent did from the couch actually works.

Everything else

The smaller things you notice after a day of use:

• Advanced search filters — narrow a query by session-id prefix, model, or a date window; filter the session list by project or to pinned-only.
• Copy the resume command — one button in the info panel yields the exact claude --resume invocation for the session, ready to paste into a terminal.
• Rich tool rendering — TodoWrite checklists, AskUserQuestion choices, and Bash output render as structured blocks, not JSON dumps; Markdown and syntax highlighting throughout.
• Position that survives navigation — jumping into a subagent and back restores your exact scroll position; every session remembers how far you have read.
• Keyboard-friendly — j/k walk messages, / focuses search, g/Shift+G jump to the ends, ? shows the full palette; skip-links cover the reader and info panel.
• Copy anything — per-message and per-code-block copy buttons.
• Custom titles, reading font size — rename cryptic sessions; tune the read
