Best Crystal Alternatives in 2026
Crystal is now Nimbalyst. Compare the best alternatives for running Claude Code and Codex in parallel Git worktrees, including Paradev, Nimbalyst, Orca, Emdash, and Conductor.
Crystal was an MIT-licensed desktop app for running Claude Code and Codex sessions in parallel Git worktrees, with in-app diff review and Git operations. Its repository now says "Crystal Is Now Nimbalyst": the last Crystal release, v0.3.5, shipped on February 26, 2026, and active development moved to Nimbalyst. If you are moving off Crystal and want more than Claude Code and Codex, Paradev runs any CLI agent in the same worktree-per-task model, with review, a browser, and automations around it.
Our recommendation: choose Paradev if you want Crystal's worktree model with any agent, PR review, and remote and cloud workspaces. If you want the direct successor, choose Nimbalyst.

Why Look for a Crystal Alternative?
- No more releases. Crystal's last release shipped in February 2026, and new agent versions will not get fixes there.
- More agents. Crystal runs Claude Code and Codex. You may also use OpenCode, Cursor's agent, Copilot CLI, Gemini CLI, or Amp.
- Reach. Crystal is a local desktop app. You may want agents on other machines or in the cloud, and a phone app.
- Unattended work. You may want scheduled agent runs.
The Best Alternatives
Paradev
Paradev runs any CLI agent, including Claude Code and Codex, each in its own Git worktree with persistent terminal sessions. Like Crystal, it keeps review in the app: the Changes pane commits, pushes, and opens PRs, and the PR pane shows checks, review threads, and merge. It adds an in-app browser with Design Mode, port management, and a Workspaces page that shows which agents need you. Workspaces run on your machine, on hosts you add through Remote Access, or in cloud workspaces, and the iPhone and iPad app reaches all of them. Pro adds remote access, the iPhone and iPad app, and scheduled automations, and a CLI, TypeScript SDK, and MCP server let agents start other agents.

Nimbalyst
Nimbalyst is where Crystal's development continues. It is an MIT-licensed visual workspace for Claude Code, Codex, and OpenCode on macOS, Windows, and Linux, with iOS and Android companions. It runs agents in parallel and adds visual editing of markdown, mockups, and diagrams, plus task tracking. Choose it if you liked Crystal and want the same team's next product.

Orca
Orca is a free, MIT-licensed desktop agent development environment for macOS, Windows, and Linux. It runs Claude Code, Codex, and many other agents in parallel worktrees with per-task browser tabs, Design Mode, SSH worktrees, scheduled automations, and beta mobile apps.
See Paradev vs Orca.
Emdash
Emdash is an Apache-2.0 desktop app for macOS, Windows, and Linux that supports 34 CLI agents. It gives each task its own branch and worktree, pulls tasks from Linear, Jira, GitHub, Notion, and Asana, and supports SSH machines and scheduled runs.

Conductor
Conductor is a Mac app that runs Claude Code, Codex, Cursor, and OpenCode in parallel workspaces. Its Pro plan at $50/month adds cloud workspaces, multiplayer, an API, and an iOS app.

How To Choose
- For any CLI agent with PR review, automations, and remote and cloud workspaces, choose Paradev.
- For the direct successor from the same team, choose Nimbalyst.
- For a free, open-source, cross-platform ADE with many agents, choose Orca.
- For open source with issue-tracker intake, choose Emdash.
- For a polished Mac app with team cloud workspaces, choose Conductor.
Verdict
Crystal still runs, but it no longer gets releases. If you want to stay with the same team, move to Nimbalyst. Choose Paradev when you want Crystal's worktree-and-review loop for every agent you use, plus remote hosts, cloud workspaces, and scheduled runs. Move one task first and compare.

What To Try First
- Bring Claude Code or Codex: launch it in a Paradev workspace with your own account.
- Run two tasks: start a second workspace on its own branch and let both agents work.
- Review in place: inspect each diff, run your checks, and open a PR from the Changes pane.
- Add an agent: give the same task to a third agent and compare the diffs.
Download Paradev, then follow the parallel-task walkthrough.
