Cmux vs OpenCode (2026): Which Vibe Coding App Is Better?

Both are popular terminal coding agents. Here is how Cmux and OpenCode stack up on price, strengths and weaknesses, and which one we would pick.

Cmux

Ghostty-based macOS terminal built for running many AI coding agents at once

7.0 /10

Pricing: Freemium

Pros

Purpose-built notification and status system (rings, tab highlights, a dedicated panel) so you can tell at a glance which of many agent panes needs attention
Sidebar surfaces git branch, PR status, working directory, and listening ports per pane; session layout, scrollback, and browser history survive a relaunch
Free and open source (GPL-3.0-or-later) with native resume integrations for a long list of CLI agents beyond Claude Code

Cons

macOS only, and still early with heavy churn (2k open issues, 1.7k open PRs) relative to its 27k stars
Founder's Edition (paid) gates the iOS app, cloud VMs and early AI features behind a tier with no public pricing listed

Pros

Free and open source; any model provider
Claude Code-style extensibility
Fast, well-designed terminal UI

Cons

You pay the model provider directly; costs vary with usage
Smaller community of ready-made extensions

Our pick

OpenCode edges it with a score of 8.4 versus 7.0. OpenCode is the better fit if you value: free and open source; any model provider, claude code-style extensibility. Choose Cmux instead if you need: purpose-built notification and status system (rings, tab highlights, a dedicated panel) so you can tell at a glance which of many agent panes needs attention, sidebar surfaces git branch, pr status, working directory, and listening ports per pane; session layout, scrollback, and browser history survive a relaunch.
