A coding agent harness for developers: a TypeScript agent plans, edits and tests your code while a native Rust layer draws the screen — the agent opens and drives its own terminal panes (zmux), and panes can hold more agents, each on its own model. Terminal, desktop app or headless.
Verdict: Zerg Client is best for developers who live in the terminal and want to watch agents work in visible panes.

No public changelog is published. VibeCodePicks verified the live site and pricing on 2026-11-07. The demo is a YouTube video, "Zerg Client (ZTC): the coding harness we built for our own work", whose title and description match the product (two halves, zmux panes, a model in each pane, terminal/desktop/headless; product footage from real sessions).

VibeCodePicks verified the live site and pricing on 2026-11-07: a coding agent harness in evaluation beta — a TypeScript agent plans, edits and tests code while a native Rust layer draws the screen over one protocol; its own multiplexer, zmux, lets the agent open terminal panes (Vim, htop) beside itself and read and type in them, and panes can hold more agents, each on its own model; runs in the terminal, in the desktop app, inside your own app, or headless on a server. Free to evaluate, including at work, under the Zerg Source Available License 1.0 (not open source); ongoing commercial use needs a separate signed license (price on request); model usage is billed separately. Terminal install is npm install -g @zergai/ztc@0.11.0-beta.1 (Node.js 20.19+ or 22.12+); desktop beta is macOS Apple Silicon only, Windows and Linux apps coming soon; headless runs on macOS, Linux and Windows. Demo video verified (title and description match the product; voiceover is AI-generated, footage is from real sessions). No independent hands-on reviews of zergai.com/ztc were found: the completeaitraining.com entry is a directory listing with generated summary, not hands-on testing; the Product Hunt post is the vendor's own launch; the digi.wo.com entry is a directory discovery listing; Zerostack reviews are a different product — all excluded per the same-product rule. No live run was done in this desk review (needs a Mac with Apple silicon and sign-in). No local clip could be made in this round: the environment file-write fault (EPERM) blocked downloading the demo video to disk, so the listing links the vendor's demo video directly. Source
