Alternative
Crystal alternative — migrate to a maintained five-CLI command center
Crystal was a free, open-source GUI for Claude Code. It is deprecated and unmaintained — fine for hobbyists who can fork it, risky for anyone who needs ongoing CLI compatibility (verified July 2026). Aiola is a maintained desktop alternative on macOS and Windows that runs Claude Code, Codex, Cursor, Grok CLI, and OpenCode with the parallel sessions and project visibility Crystal users typically wanted next: git worktrees, tasks, automations, analytics, app logs, feedback, and a central cross-project view.
The short answer
Crystal served early Claude Code GUI users well, but it is Claude-only, open source, and no longer maintained. Choose Crystal only if you will self-maintain a fork. Choose Aiola if you want a supported path forward — five agent CLIs, parallel worktrees, automations, the operations layer, and a GUI Lifetime license — without carrying a deprecated project.
Feature comparison
Choose Aiola if…
You relied on Crystal for a Claude Code GUI and need a maintained product — Crystal is deprecated and no longer a safe long-term bet.
You outgrew a single-vendor GUI and want Claude Code, Codex, Cursor, Grok CLI, and OpenCode orchestrated from one desktop app.
You need what Crystal users typically wanted next: true parallel sessions across projects, git worktrees so agents do not collide, and a central view of all repos.
You want automations, analytics, app logs, and feedback for the products you ship — not just a terminal replacement with a window.
You are on macOS or Windows and want commercial support with a GUI Lifetime license instead of self-maintaining a dead OSS fork.
Choose Crystal if…
You are comfortable staying on deprecated open-source software and forking or patching Crystal yourself.
You only ever used Claude Code and do not need Codex, Cursor, Grok CLI, automations, or an operations layer.
You want zero cost and full source access, and accept that security fixes and CLI compatibility are your responsibility.
You need a minimal Claude-only launcher and do not plan to run multiple agents in parallel across several repos.
Comparison FAQ
What happened to Crystal?
Crystal was an open-source GUI for Claude Code. It is now deprecated and unmaintained (verified July 2026). Users who depended on it for a friendlier Claude Code surface need a maintained alternative that keeps pace with CLI changes.
What should Crystal users look for in a replacement?
Most Crystal users wanted three things: a GUI instead of raw terminals, the ability to run more than one Claude Code session, and less context switching between projects. Aiola delivers that and goes further — parallel threads with git worktrees, five agent CLIs (Claude Code, Codex, Cursor, Grok CLI, OpenCode), automations, and an operations layer for shipped products.
Is Aiola open source like Crystal?
No. Crystal was open source and free. Aiola is a commercial, actively maintained desktop app. The download includes a 7-day trial; Pro starts at $24/month. GUI Lifetime is available now at launch pricing: first 10 customers $49, next 30 $89, then $129. One-time payment. You trade OSS inspectability for maintained cross-vendor orchestration and ops features.
Can Aiola run Claude Code locally like Crystal?
Yes. Aiola is local-first: Claude Code runs on your machine against your repositories using your own subscription. Your code stays on your machine; prompts and file context go only to the provider you choose. Aiola also adds Codex, Cursor, Grok CLI, and OpenCode in the same workspace.
Why not use opcode or another free Claude GUI instead?
opcode and other free GUIs remain valid Claude-only choices. Aiola is aimed at Crystal refugees who have already outgrown a single-vendor launcher — you want parallel multi-project sessions, worktrees, five CLIs, automations, and analytics without maintaining a deprecated fork.
Current Aiola facts
Aiola supports five agent CLIs: Claude Code, Codex, Cursor, Grok CLI (including grok-4.5), and OpenCode.
GUI Lifetime is available now at launch pricing: first 10 customers $49, next 30 $89, then $129. One-time payment.
Your code and repos stay on your machine. Agent prompts and file context are sent only to the AI provider you choose — Anthropic (Claude Code), OpenAI (Codex), Cursor, xAI (Grok CLI), or whichever provider you configure in OpenCode — under your own subscription. Aiola never proxies, stores, or resells your code or model traffic. Threads, tasks, notes, and automations are stored locally (SQLite + plain files in your repo). If you use the optional analytics/logs/feedback layer for your shipped products, that telemetry is ingested via Aiola's cloud (Supabase/Tinybird). Offline: agent orchestration UI works offline; running agents requires provider access; GUI Lifetime keeps the local app opening even if Aiola's servers are unreachable.
