C

cmux

open sourcedesktopone-click install

A native Mac workspace for terminals, browsers and agent notifications; repos remain folders.

licenseGPL-3.0+

runson your machine

installDrag the signed macOS app from its DMG into Applications, or install the Homebrew cask

enginesAny terminal-based coding agent installed on the Mac, including Claude Code, Codex, OpenCode, Gemini CLI, Kiro, and Aider

dataConfiguration, workspace state, and terminal scrollback live on the Mac; the optional iOS companion connects over the user's local network or Tailscale rather than a vendor relay

the catch vs Uncirclecmux is an excellent terminal workspace, but it does not provide Uncircle’s declarative per-project stack, one-click parallel startup, process health view, and automatic restart.

setupmacOS only; each coding-agent CLI and its account or API credentials must be installed separately

W

Wave Terminal

open sourcedesktopone-click install

Repos, terminals, previews and remote files in one window; agents are just commands.

licenseApache-2.0

runson your machine

installInstall the signed desktop package for macOS, Windows, or Linux

enginesOpenAI, Anthropic Claude, Google Gemini, Azure OpenAI, Perplexity, custom OpenAI-compatible endpoints, local Ollama/LM Studio/vLLM, and Claude Code integration

dataWorkspace and terminal configuration live under the user's local Wave configuration directory; files stay local or on connected SSH hosts, while AI prompts go to the selected provider unless a local backend is used

the catch vs UncircleWave combines terminals, files, and previews, but it lacks Uncircle’s checked-in project stack definitions, status dashboard, and automatic process restart.

setupThe terminal installs normally; AI features require a provider API key or a separately running local model, and remote files require SSH credentials

N

Nimbalyst

open sourcedesktopmobileone-click install

A visual desktop for several coding agents; repos and terminals stay in the same room.

licenseMIT

runson your machine

installInstall the signed macOS DMG, Windows installer, or Linux AppImage and point it at already installed coding-agent CLIs

enginesCodex and Claude Code, with OpenCode and GitHub Copilot support described as alpha

dataProjects and planning artifacts are local-first and stored as ordinary files, including Markdown; optional sync and mobile access use Nimbalyst services

the catch vs UncircleNimbalyst orchestrates coding agents but does not supervise the surrounding dev servers, workers, databases, and restartable project processes that Uncircle treats as first-class.

setupRequires at least one supported coding-agent CLI to be installed and authenticated separately

why people still pay for Uncircle

It is $19 once with a free tier that covers 3 projects, so the honest calculus is not subscription math · it is whether an evening of vibe coding beats a lifetime license. People pay for the parts that are tedious to get right: clean shutdown of whole process trees, restart backoff that does not flap, native notifications when an agent finishes or crashes, and updates they never think about.
