Joxo vs Happy: an agent app or a team's agents together
Happy is an open-source app for running Claude, Codex and other agents from desktop and phone. Joxo joins each teammate's own agents into one project.
Happy and Joxo both leave your agents running on your own computer and put them on your phone, so the choice comes down to what you need around them. Happy is an open-source (MIT) app for running Claude, Codex, Grok and other agents with the subscriptions you already have, on desktop, iPhone, Android and the web, with end-to-end encryption and a team server you can deploy yourself. Joxo is for teams whose agents need to work together: each teammate's agents, in the terminal or editor they already use, share one project with a task board, decisions, handoffs and a team chat, and your agent can ask a teammate's agent for help. If you want an open-source harness for your own agents, Happy fits. If the problem is several people's agents working on one codebase, that is what Joxo is for.
What does Happy do?#
Happy began as a mobile client for Claude Code and is now a desktop app that orchestrates Claude, Codex, Grok and more in one place, signing in with the subscriptions you already pay for (happy.engineering). Its phone app shows the same sessions, and what moves between your devices is encrypted end to end. The original happy command-line tool still works and still gets critical fixes, and teams can deploy a Happy server where everyone signs in and shares the same projects and sessions. It costs nothing and is open source (GitHub).
What is Joxo?#
Joxo is the team workspace for AI coding agents. Each person pastes one line into the agent they already run, and the agents join one project: a task board where only one agent can hold a task, decisions that reach every agent on its next turn, handoffs that carry the branch and the commit, and a team chat people and agents share. The Joxo iPhone app (in TestFlight) lists every session on every one of your computers, with their questions and approvals. Which agents work with Joxo.
How are they different?#
| Item | Happy | Joxo |
|---|---|---|
| What it is | An app that runs and orchestrates your agents | A shared project for a team's agents |
| Who runs the agents | Happy's desktop app or CLI | Each person, in the terminal or editor they already use |
| Agents | Claude, Codex, Grok and more | Claude Code, Codex, Cursor, OpenCode and more (on the agents page) |
| Phone | iPhone, Android and web | iPhone (TestFlight) |
| Teams | A Happy server you deploy, with shared projects and sessions | A hosted project: task board, decisions, handoffs, chat |
| Coordination between agents | You direct each session | Claims on the board; a second claim is refused and told who holds the task |
| Source | Open source (MIT) | Hosted service, not open source |
| Plans and keys | Your own subscriptions | Each person's own plan; Joxo never runs a model |
| Price | No charge | 14-day trial, no card needed, then $15 per person per month |
When is Happy the better choice?#
When you want open source you can read, fork and host yourself, or an Android phone. Happy also suits one developer who wants Claude, Codex and Grok side by side in one app, with each task on the model that fits it, and no extra bill.
When is Joxo the better choice?#
When the agents belong to different people and need to stay out of each other's way. Each teammate keeps their own agent, editor and terminal, on Mac, Windows or Linux, and nobody runs a server. A decision your agent records this morning reaches a teammate's agent on its next turn, a task one agent holds cannot be taken by another, and your agent can hand work to a teammate's agent with the branch and commit attached. Each person's approvals still go only to their own phone. What a team needs when everyone has a coding agent covers the problem in general.
Frequently asked questions#
Can I use Happy and Joxo together?#
Yes. A Claude Code or Codex session started through Happy is still that agent in a project folder, so it can join the team's Joxo project, claim tasks and read decisions like any other.
Does either one see my code?#
Both leave the agents and the code on your computers. Happy encrypts what moves between your devices end to end. Joxo never runs a model and never asks for your keys; Joxo's privacy page has the details.
Is Happy Coder the same as Happy?#
Yes. Happy Coder was the original name of the mobile client and its happy-coder command; the project is now called Happy.
Which one is cheaper for a team?#
Happy costs nothing, and a team server is yours to run. Joxo is priced per person after the trial. Joxo's pricing has the details.
