Wave Terminal
open sourceApache-2.0Local22kaug 2026Repos, terminals, previews and remote files in one window; agents are just commands.

Frequently Asked Questions
Direct answers · Uncircle open-source replacements
What is the best free alternative to Uncircle?+
The top free alternative to Uncircle is cmux (open source, GPL-3.0+). A native Mac workspace for terminals, browsers and agent notifications; repos remain folders. Other popular Uncircle replacements include Wave Terminal, Nimbalyst.
Should I vibe-code or build my own Uncircle clone from scratch?+
Our build verdict for Uncircle is KINDA (the core, yes. the polish, no). The core loop · read a yml of processes from the repo, run them, stream logs into terminals, show status dots · is a genuine one-sitting build with node-pty and xterm.js, and mprocs already gives you most of it in a TUI for free. What does not one-shot is everything around it: a native window with tray and notifications, killing whole process trees without orphans on three OSes, crash auto-restart that does not flap, and signed auto-updating builds. And since the paid tier is $19 once rather than a subscription, the usual death-list math barely applies.
What is the catch when switching from Uncircle to cmux?+
cmux 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.
