A handful of apps now let you talk to an AI coding agent from your phone. They’re all good — they’re just built for slightly different people. Here’s an honest look at where Zucchini fits, including the things the others do that we don’t.
Most apps in this space are built for developers and organised around sessions — one row per agent run, terminal-style chrome. Zucchini is a messenger app: you talk to your agents the way you’d text a person, and it’s made for everyone — whether or not you write code. Each task is a chat you can pin, rename, search, and pick up from any device, the same way you already use any messaging app.
Two things are ours alone in this list:
Zucchini also isn’t Claude-only — it runs Claude Code, Codex, Gemini, Cursor, and Hermes from the same chat list.
The other apps are Happy, Code Messenger, Paseo, Vicoa, and Omnara. Cells reflect each app’s public listing as of May 31, 2026 and will drift as everyone ships — if something here is wrong or out of date, tell us at [email protected] and we’ll fix it.

The table marks Zucchini source-available, not open source, and the difference matters. Both the spawner that runs on your machine and the mobile app are published so anyone can read, audit, and verify them — in particular, confirm that your messages really are end-to-end encrypted before they leave your device. What that doesn’t mean: there’s no permissive licence, we don’t take outside pull requests, and the code isn’t there for anyone to lift into their own product. Happy and Paseo, by contrast, are genuinely open source (MIT) — free to fork and reuse. Pick the model that matches what you care about: auditability either way, reuse only with the MIT ones.
All of these are worth a look. Here’s the short version of what each is best at — including where it beats us today.
Open source (MIT) and the most cross-platform of the bunch — iPhone, Android, web, and a CLI, all free. Talks to Claude Code and Codex, with a hands-free voice assistant as its headline paid feature. The desktop client is the web app rather than a native Mac one.
Best for: developers who want a free, hackable, open-source client and control by voice.
Privacy-first by design: a peer-to-peer architecture where content is never cached on a server. Ships a full file browser and a faithful terminal view, focused on Claude Code. The free tier is generous but capped by the number of device pairings.
Best for: developers who want a terminal-grade remote with the strongest no-server privacy story.
Free and open source, self-hosted by default, and by far the most agent-agnostic — Claude Code, Codex, OpenCode, Copilot, Pi, and dozens more, run in parallel. The deepest developer toolkit here too: split-view diffs, a file-tree browser, voice, git worktrees, slash commands, a terminal view, localhost preview, and even scheduled (cron) tasks — all at no cost.
Best for: tinkerers who run many different agents and want everything free and self-hosted.
A mobile-IDE take: fuzzy file search, slash commands, permission-mode switching, and table-formatted output, across iPhone, Android, and web. Works with Claude Code, Codex, and OpenCode. The free tier includes a set number of messages; the subscription lifts that cap.
Best for: developers who want an IDE-like mobile workflow with file search and slash commands.
The only one with an Apple Watch app. Built around watching and approving long agent runs — two-way voice, live localhost previews, and an approve-the-next-step workflow for Claude Code and Codex. A free monthly session allowance, with unlimited sessions on the paid plan.
Best for: people who want to babysit and approve long-running agents on the go, even from their wrist.
If you want voice, Android-plus-web everywhere, fully open source, or a terminal-grade remote, one of the apps above will serve you better today, and we’d honestly point you there. If you want talking to an agent to feel like texting — and to invite other people onto a machine without making them set anything up — that’s what Zucchini is for. If you switch from one of these, we’d genuinely like to hear what made you move.
