Session Steward

A local Codex and Claude Code session manager for safely reviewing, backing up, and deleting old sessions from a browser UI or terminal CLI.

AI coding tools can accumulate hundreds or thousands of local sessions. A session may leave behind transcripts, history, logs, checkpoints, and linked artifacts, so manual cleanup can easily miss related data.

Session Steward makes session cleanup safer by finding those records, showing what cleanup will affect, creating a local backup, removing supported data, and verifying the result afterward. Everything runs locally, and your session data stays on your computer.

Manage local Codex and Claude Code sessions

• Review sessions in a browser UI or terminal CLI.
• Switch between Codex and Claude Code without installing another package.
• See session counts and the storage used by recognized session files.
• Find sessions inactive for 30, 60, or 90 days.
• Filter active or archived sessions by workspace, name, or session ID.
• Inspect session details and affected records before deletion.
• Read a session timeline of what you asked, what changed, and which commands ran.
• Choose standard or thorough cleanup.
• Use custom Codex or Claude home folders across browser and terminal sessions.

Safe by default

• Cleanup happens entirely on your computer.
• Only records included in the reviewed cleanup plan are removed.
• A local recovery backup is created before anything changes.
• Cleanup is verified before the backup is removed.
• Unrecognized storage is reported and left untouched.
• Thorough cleanup is unavailable when the detected storage format is not supported.
• Session contents are never sent over the network.

At startup, Session Steward may contact the public npm registry to check for a newer version.

Session Steward does not remove

• Sign-in data or saved API credentials
• Configuration, plugins, caches, or custom prompt files
• Project files, Git repositories, or worktrees
• Sessions outside the reviewed cleanup plan
• Conversations stored in your ChatGPT or Claude account
• Claude Code worktrees, branches, repositories, remote sessions, SSH sessions, or Cowork data

Install and get started

Session Steward supports macOS, Linux, and Windows and requires Node.js 24.15 or newer.

Install it globally:

npm install --global session-steward

Then launch it:

session-steward

Or try it without installing:

npx session-steward@latest

Session Steward opens in your browser, listens only on 127.0.0.1, and detects ~/.codex and ~/.claude by default. Claude Code CLI and local Claude Desktop sessions are detected on macOS and Windows; the Claude Code CLI is also supported on Linux. On Windows, these resolve to %USERPROFILE%\.codex and %USERPROFILE%\.claude.

When run inside WSL, Session Steward uses the Linux home folder and manages sessions stored there. Run it from Windows to manage sessions in your Windows profile.

To clean up sessions:

1. Review the detected sessions.
2. Select one or more sessions.
3. Choose a cleanup option.
4. Review exactly what will be removed.
5. Close any selected sessions that may still be active.
6. Confirm the cleanup.

Keep the terminal open while using Session Steward. Press Ctrl+C to stop it.

Cleanup and recovery

Standard cleanup

Recommended for routine removal. It removes supported transcripts, history, registry entries, logs, and linked session artifacts belonging to the selected sessions.

Thorough cleanup

Includes standard cleanup and removes additional recognized session-owned data. For Codex this can include supported Desktop references, memory outputs, and goal records. For Claude Code this includes recognized file checkpoints.

Thorough cleanup is unavailable when Session Steward finds storage it does not recognize. Standard cleanup remains available for supported records that can be identified safely.

Recovery backups

A temporary backup is created inside the active provider folder under session-steward-backups/.

After cleanup is successfully verified, the backup is removed automatically. If cleanup fails, Session Steward keeps the backup and lets you restore the sessions, keep the backup, or delete it.

Before restoring, the current versions of affected files are saved separately to provide another recovery point.

Terminal CLI

Start the interactive terminal interface:

session-steward-cli

Use Claude Code instead of Codex:

session-steward-cli --provider claude-code

List sessions as JSON:

session-steward-cli --json --limit 10

Show session and workspace storage totals:

session-steward-cli --overview

Add --json when the output will be read by another tool.

Find sessions inactive for at least 60 days:

session-steward-cli --inactive-days 60

Show only archived sessions:

session-steward-cli --archive-status archived

Show sessions from one exact workspace:

session-steward-cli --workspace /path/to/project

Use --include-internals to include subagents and --include-supporting to include supporting sessions. Session sizes are shown in the interactive list, and --sort size places the largest sessions first.

Start with --events to read what happened inside a session — what you asked, what the assistant concluded, which files changed, and which commands ran or failed. In the interactive list, inspect <number> then shows that session's timeline:

session-steward-cli --events --events-limit 50

With --json, each session carries its own events, plus a coverage summary of how much of the transcript was recognized:

session-steward-cli --json --limit 5 --events

The interactive terminal accepts the same filters:

inactive 30
inactive 60
inactive 90
archive active
archive archived
workspace /path/to/project
internals
supporting
cleanup standard
cleanup thorough
overview
backups

Run inactive, archive, or workspace without a value to clear that filter.

backups lists recovery backups retained after an interrupted or unsuccessful cleanup. Use restore <number> to restore one, or delete-backup <number> to remove it permanently. Both actions require an explicit confirmation.

Use session-steward-cli --help to see all available options.

Use a custom provider folder

The browser interface displays the active provider folder. Select Change to choose another existing folder and remember it for later browser and terminal sessions.

For a one-time override:

session-steward --codex-home /path/to/.codex

For Claude Code:

session-steward --claude-home /path/to/.claude

The command-line override applies only to that run and does not replace your saved folder.

Other commands

Start without automatically opening the browser:

session-steward --no-open

Update Session Steward:

npm install --global session-steward@latest

Uninstall it:

npm uninstall --global session-steward

Uninstalling Session Steward does not remove provider sessions, recovery backups, or saved folder preferences.

Troubleshooting

• The browser did not open: Run session-steward --no-open, then open the local address shown in the terminal.
• No sessions were found: Check the selected provider and displayed home folder. Use Change or pass a one-time home-folder override.
• Thorough cleanup is unavailable: Review the compatibility details. Unrecognized storage is left untouched, but standard cleanup may still be available.
• Your Node.js version is too old: Install Node.js 24.15 or newer and run Session Steward again.

Development

git clone https://github.com/mallikcheripally/session-steward.git
cd session-steward
npm install
npm test
npm run build

Performance and scale

Session Steward uses paginated listings, incremental transcript reads, and bounded caches to remain responsive with large session libraries.

Current synthetic benchmarks on an arm64 Mac with Node.js 24.15.0:

| Scenario | Scale | Time | Measured memory growth | | --- | ---: | ---: | ---: | | Paginated session listing | 50,003 sessions | 26 ms | 0.16 MB heap | | Session size index | 20,003 sessions | 85 ms cold, 9.7 ms warm | 30 MB peak RSS | | Transcript-only discovery | 5,003 sessions | 662 ms | 4.02 MB heap |

Run the scale benchmarks with:

npm run benchmark:scale
npm run benchmark:overview
npm run benchmark:size
npm run benchmark:discovery
npm run benchmark:transcripts

Results vary with hardware, disk speed, and session layout. Tests and benchmarks use temporary synthetic data and do not read or modify your local sessions.

Support

Codex, Claude Code CLI, and local Claude Code Desktop sessions are supported. Claude Desktop archive is not treated as deletion, and Session Steward never removes its worktrees. On Windows, both the standalone and Microsoft Store Claude Desktop data locations are detected.

Use GitHub Issues to report a bug, request a provider, or share a storage format that Session Steward does not recognize.
