Session tools compared

Compare session history tools and agent workspaces by how they help you return to existing work.

The difference in one sentence

Agent Sessions: Agent Sessions finds answers across local transcripts; JustSessions takes you from reading an existing conversation to working in its original CLI inside the same app.
opcode: opcode gives Claude Code a graphical interface; JustSessions keeps the familiar terminal interface across six coding CLIs.
cmux: cmux centers on agent terminals and workspace restoration; JustSessions centers on browsing saved conversations across projects and your own SSH hosts.
Superset: Superset gives parallel project tasks isolated Git workspaces; JustSessions resumes saved conversations in their original project folders without requiring a worktree.

cmux also supports SSH workspaces, and Superset also supports native CLI resume and fork. These sentences describe differences in focus.

Closest history tools

JustSessions, Agent Sessions, and opcode compared by history, continuation, remote workflow, and focus
Your workflow	JustSessions	Agent Sessions	opcode
Find and read past work	Existing history from six CLIs, grouped by project; message search	16 active local agent formats; full transcript search	Existing Claude Code projects and session history
Continue a conversation	Original CLI inside native tabs, in the original project folder	Supported CLI sessions in Terminal, iTerm2, or Warp	Claude Code through a graphical session interface
Work on your own SSH host	Browse cached history; resume the CLI on the host	SSH history workflow not documented*	SSH history workflow not documented*
Main focus	Read history and work in familiar CLIs, local or remote	Search history across tools and inspect usage	Claude Code sessions, custom agents, and checkpoints

Documentation checked October 5, 2026. *Not documented means the reviewed sources do not establish that workflow. Capabilities vary by CLI; this is a documentation comparison.

Other ways to work with agents

These tools solve adjacent needs, from phone access to parallel tasks and everyday terminal work.

Remote clients

Paseo: Paseo controls daemon-managed agents from desktop, web, and mobile; JustSessions browses existing history and resumes the original CLI on your Mac or SSH host.
Happy: Happy lets you take over wrapped Claude Code and Codex sessions from your phone; JustSessions keeps your saved conversations and original CLI terminals together on your Mac.

Parallel agents

Claude Squad: Claude Squad runs parallel agents through a terminal UI with tmux and Git worktrees; JustSessions adds a native history reader and resumes work in existing project folders.

Terminals

Warp: Warp enhances running CLI agents with rich input, notifications, and code review; JustSessions focuses on finding saved conversations, reading them, and reopening the original CLI.
Ghostty: Ghostty provides a general-purpose terminal with native UI; JustSessions adds a project-organized conversation library and reader around your coding CLIs.
iTerm2: iTerm2 integrates persistent tmux sessions into native windows; JustSessions pairs keep-running agent terminals with a library of readable, resumable conversations.

JustSessions has no mobile client or integrated code review. Its tmux processes keep running while their machine stays awake; a resumable conversation and a live process are different things.

A good fit for your workflow?

JustSessions is for Mac developers who switch between coding CLIs and return to work across projects or their own SSH machines. Read an existing conversation, then continue in the CLI you already know, in the same app. No Git worktree workflow is required.

Choose Agent Sessions when you want more agent formats or usage insights. Choose opcode when you want a Claude Code GUI with custom agents and checkpoints.

JustSessions searches project names and paths, session titles and IDs, and message text up to each message's preview limit. SSH requires passwordless access, rsync, and the installed CLI; some providers also need Python 3. With tmux, agent processes can keep running after you quit the app while their machine stays awake.
