clack

A terminal UI for browsing, searching, and resuming Claude Code sessions.

Browse your full session history, read past conversations, jump into stats, and resume any session — all without leaving the terminal.

---

Install

# pipx
pipx install clack-tui

# uvx (run without installing)
uvx clack-tui

The package name is clack-tui because clack is already taken on PyPI. The package installs both clack and clack-tui executables.

Requires Python 3.11+ and Claude Code installed.

Quick start

clack

clack reads your Claude Code session files directly from ~/.claude/projects/ — no configuration needed.

---

Features

Tab	Key	What it does
Dashboard	1	Browse all sessions, search with full-text search (DuckDB FTS / BM25)
Stats	2	Token usage and model breakdown, daily sparklines
Dialog	3	Read any conversation turn-by-turn, export to HTML
Query	4	Write SQL directly against your session data (DuckDB)

Dashboard key bindings

Key	Action
/	Focus search
Esc	Clear search
Enter	Resume session (opens claude --resume)
v	View full conversation
r	Refresh session list
q	Quit

tmux: If clack is running inside a tmux session, resuming opens the session in a new tmux window. Otherwise it suspends the TUI, runs claude --resume, and returns when you exit.

If the DuckDB FTS extension is unavailable, dashboard search falls back to simple substring matching.

Query console

The Query console exposes your session data as DuckDB SQL views:

View	Contents
v_sessions	One row per session — date, project, summary, model, turn count
v_assistant_turns	Individual assistant turns with token counts
v_stats	Aggregated usage by model
v_sessions_by_day	Daily session and token totals
raw_records	Raw JSONL records

Example queries:

-- Sessions from the last week
SELECT title, cwd, turn_count FROM v_sessions
WHERE last_active > now() - INTERVAL '7 days';

-- Most token-heavy sessions
SELECT sessionId, SUM(output_tokens) AS total
FROM v_assistant_turns GROUP BY 1 ORDER BY 2 DESC LIMIT 10;
