Crystal alternatives

TL;DR

Crystal, the early app for running Claude Code sessions in parallel worktrees, stopped getting updates in February 2026, and its makers now point people to Nimbalyst, a different and broader product. If you want Crystal's workflow in a maintained app, Pane is the closest: parallel agents in worktrees with diffs and git, but with any CLI agent, each in its real terminal, and on Windows and WSL too, which Crystal never shipped. Emdash, T3 Code and Paseo are other maintained options.

the alternatives

Every tool here runs several coding agents at once in their own git worktrees and is actively developed. The chips show where each one runs: green is native, amber has a catch, red is no.

  1. 1.Pane

    Best for Crystal's workflow in a maintained app, on every OS.

    Parallel agents in worktrees with diffs, commit, push and merge, plus any CLI agent in its real terminal, Windows, WSL and an orchestrator. Free, open source, no account.

  2. 2.Emdash

    Best for a desktop app with issue intake and automations.

    35 agents, tasks from 12 trackers, Apache-2.0. Windows x64, macOS and Linux; no WSL.

  3. 3.T3 Code

    Best for a polished chat view, like Crystal's, with phone apps.

    Shows agents as chat threads, MIT-licensed, iOS and Android apps. Young at version 0.0.x.

  4. 4.Paseo

    Best for phone control and agent-to-agent automation.

which one should you pick?

stay on crystal if

  • → your setup still works and you're happy with no updates
  • → or move to Nimbalyst, the successor its makers recommend

pick pane if

  • → you want a maintained app with the same parallel-worktree loop
  • → you're on Windows or WSL
  • → you use agents beyond Claude Code and Codex
  • → you want push and pull requests from the same window

Facts checked on October 3 and 4, 2026: Crystal v0.3.5 (final) and Pane v2.4.157.

what happened to crystal

Crystal is frozen, and agent managers that can't follow agent updates eventually break.

Crystal's final release, v0.3.5 on February 26, 2026, only added a notice that it won't be updated, and it opens with a popup pushing Nimbalyst. It drove Claude Code and Codex through their output formats, and it already broke once when Codex changed its format. It never shipped a Windows build, and its macOS builds weren't signed.

moving from crystal to pane

Your worktrees and branches are plain git; open the repo in Pane and carry on.

Commit or merge what you want to keep, open the repository in Pane, and create a pane per feature; Pane makes a fresh worktree and branch. Claude Code conversations live in Claude Code's own history, so you can resume them in a pane with claude --resume. You won't find Crystal's nested folder tree or automatic per-prompt commits; you gain any agent, Windows and WSL, push and pull requests, and an app that's still developed.

our verdict

Pane is the most direct maintained replacement for Crystal's parallel-worktree workflow, and it adds Windows, WSL and any agent. If you'd rather stay with Crystal's makers, they recommend Nimbalyst.

how we checked

On October 3 and 4, 2026 we ran Crystal's final Linux build under WSLg as far as it would go, and ran Pane, Emdash, T3 Code and Paseo on the same Windows 11 PC with the same task.

Facts about each product come from its own docs, release notes, issue tracker and source code, checked on the same dates.

What we ran
  • → Pane 2.4.155 on Windows 11, native and WSL2 (Ubuntu 24.04) repos
  • → Each alternative checked against its own docs, releases and issue tracker on October 3 and 4, 2026, and run hands-on where it runs on Windows or WSL
Who wrote this
We make Pane, so we have a stake in this. We tried to be fair: Crystal's strengths are listed as plainly as Pane's, every claim was checked against the product itself or its docs and source, and the screenshots are unedited captures from our own runs.
