Sessions searchable

You have hundreds of sessions. Now what?

Claude Code and Codex stash every conversation as JSONL under ~/.claude/projects/ and ~/.codex/sessions/. After a few weeks of heavy use, the problems compound:

Lens is the local-only browser that closes the loop.

What you can do

Six things you'll use every day — without ever opening a terminal to grep your JSONL files.

Search

Find any session in seconds

Instant filter on title, project, branch, or model. When metadata isn't enough, drop into full-text grep across every JSONL body.

  • Timeline view groups results by day — remember when you fixed what
  • Card and list layouts persist per user
  • Search results sortable by relevance, recency, tokens, or messages

Resume

One click. Right back to coding.

Open the session in Terminal or iTerm at the original cwd, or copy the resume command to your clipboard.

  • No remembering UUIDs
  • No cd-ing into the right repo first
  • Works for both claude --resume and codex resume

Usage

See where your tokens went

Per-tool dashboards with rolling 5h / 24h / 7d / 30d buckets — broken down by model and project, with an activity heatmap and streak stats.

  • Live subscription quota — opt-in probe of your Claude Code OAuth token
  • Codex limits via local codex app-server probe (no consent needed)
  • Activity heatmap, longest streak, most active day

Workspace

Map your agent's environment

Browse CLAUDE.md, AGENTS.md, Skills, Commands, Hooks/Rules, Plugins, and Settings — everything that shapes how the agent behaves, in one view.

  • Read rendered Markdown or raw config side by side
  • Jump to any file in Finder with one click
  • Per-source split: Claude's plugins vs Codex's rules

Sidebar source switcher between Claude Code and Codex

Claude Code

~/.claude/projects/

Anthropic's CLI for coding. Lens reads every JSONL it writes, surfaces the Anthropic OAuth quota, and resumes sessions via claude --resume.

OpenAI Codex

~/.codex/sessions/

OpenAI's terminal coding agent. Lens parses its rollout files, pulls live limits from codex app-server, and resumes via codex resume.
