# Halterio > Halterio is a desktop app for people who use AI coding agents. It runs several agents at the same time, gives each one its own copy of the code so they don't get in each other's way, and shows in one window which agent needs you, what each one changed, and its pull request. It works on macOS, Windows and Linux, needs no account, and is in public beta (version 0.4.0). ## Pages - https://halterio.com/ : the landing page - https://halterio.com/agents : the nine coding agents it runs, the command each uses, how Halterio drives it, and what it adds to every agent - https://halterio.com/pricing : the free app, Halterio Cloud's three plans, a side-by-side comparison, how hours work, and pricing questions - https://halterio.com/download : downloads for macOS, Windows and Linux, the first launch on each, and what you need before you start - https://halterio.com/faq : questions and answers about the beta, the agents, your data, Cloud and installing - https://halterio.com/account : sign in, sync between devices, and Halterio Cloud billing (needs an account; not indexed) ## In one sentence Run ten agents. Miss nothing. Halterio is the place where you run and supervise all your coding agents, the way an inbox is the place where you handle all your email: it tells you which agent needs you, and keeps quiet about the rest. ## Who it is for - Developers who already use a coding agent such as Claude Code or Codex in a terminal, and want to run more than one at a time. - Anyone who loses track of which terminal tab has an agent waiting for an answer. - Teams of one who want agents to keep working while they are away from the desk. ## The problem it solves Coding agents are fast, but running them in terminal tabs does not scale: 1. You can't see which agent is waiting for you, so agents sit idle. 2. Two agents working in the same folder edit the same files and break each other's work. 3. Checking what an agent did means switching between the terminal, an editor and GitHub. 4. When you leave the computer, the agents stop as soon as they have a question. ## What Halterio does about it - **Runs many agents at once.** Supported agents: Claude Code, Codex, Cursor, Devin, Grok, Hermes, Pi, opencode and Antigravity. Halterio uses the command-line tools you already have installed and signed in to, with your existing plans. - **Gives every session its own copy of the code.** Each session can run in its own git worktree (a separate checkout on its own branch), so ten agents can work on ten tasks without collisions. - **Tells you who needs you.** The sidebar works like an inbox. Sessions waiting for an answer or a permission move to "Needs you". You can snooze a session, and a session settles by itself when its pull request merges. - **Keeps the review next to the work.** Each session shows the transcript, the diff, the files, terminals and its pull request in the same window. You can commit with a drafted message and open a pull request from there. - **Works when you are away.** Pair a phone or another computer once, end-to-end encrypted, with no account. You can follow sessions and answer an agent's question from your phone. Phone apps for iPhone and Android are in testing. When a plan's usage limit stops an agent, Halterio resumes it after the limit resets. - **Lets one agent lead others.** Every session gets Halterio's MCP tools. An agent can start helper agents (on any supported agent, each in its own worktree), wait for them, answer their questions and collect their results. - **Lets agents see.** Agents can write HTML designs that you comment on by clicking an element, look at iOS Simulators and Android Emulators, show charts in the chat, and, if you switch it on, use apps on your computer (Computer Use, off by default). - **Runs on a server too.** The same engine runs headless (`halterio headless`) on a build machine or a VPS, and the desktop app or a phone can control it. ## Why choose it - **Native and light.** Written in Rust, no web view. About 200 MiB of memory and under 1% of a CPU core when idle. - **Local-first and private.** No sign-up. Sessions and settings stay on your machine (`~/.halterio`, or `%LOCALAPPDATA%\Halterio` on Windows). Multi-device sync is optional. - **Not tied to one vendor.** Switch between agents per session, and switch between accounts of the same agent. Usage meters show how much of each plan is left. - **Safe defaults.** Computer Use is off until you turn it on and never types into terminals, password managers or system prompts. Remote devices get only the permissions you give them. ## Everything Halterio does today ### Agents and harnesses - Nine harnesses: Claude Code, Codex, Cursor, Devin, Grok, Hermes, Pi, opencode and Antigravity - Model and effort pickers for every session - Steer or interrupt a run; answer questions and permission prompts inline - Switch accounts, watch plan usage, resume after a usage limit resets - Uses the CLIs and plans you already have ### Agent orchestration - A lead agent starts helpers on any harness through Halterio's MCP server - A git worktree per helper; wait for any or all of them - Helpers report back with a status, a summary, their branch and pull request - Limits on how deep helpers go and how many run at once, and Stop all - Mesh: start and follow agents on your other computers ### Review and ship - A fresh git worktree or the folder itself, per session - Diff, files and terminals beside the transcript - Commit with a drafted message, then open the pull request - Pull requests stay with their session, which settles when they merge - A review queue, and review comments that go back to the agent ### Design canvas and visuals - Agents write clickable HTML designs into your repo - Comment on any element; tweak sliders write back to the file - Desktop, tablet and phone sizes, and a canvas of every design - Charts, diagrams and reports shown right in the chat - A browser pane where a comment on a page goes to the agent ### Computer, devices and automations - Computer Use and the desktop tool, off until you switch them on - iOS Simulators and Android Emulators streamed into the side pane - Automations on a schedule, on git or pull request events, or from Linear - Appshots and on-device voice input on macOS - Open any session in Cursor, VS Code, Zed or Terminal ### Everywhere you work - An inbox sidebar: Needs you, snooze, undo, and ⇧⌘J to the next one - Direct Link: pair a phone or computer once, end-to-end encrypted, no account - iPhone and Android apps, in testing now - A headless engine for build boxes and servers - Thirty themes, or import yours from VS Code ## On the way Planned for upcoming beta versions. Planned, not promised: the order can change. - Code-signed installers for macOS and Windows - The iPhone and Android apps in the App Store and Google Play - Import Claude Code, Codex and opencode CLI sessions - Several accounts per provider at once, with failover - Edit and resend, or fork from any message - Multi-repo tasks: one session across several repositories - Find in chat, and multiple windows - A remote terminal and machine view over Direct Link - Webhook triggers for automations - Open a remote checkout in VS Code or Cursor over SSH ## Pricing - The Halterio app is free: on your own computer, and on your other computers, servers and phone (Direct Link, mesh, the headless engine). No account is needed. - Syncing between your devices is free, with a free Halterio account. - Your agents use your own plans (Claude, ChatGPT and so on). Halterio doesn't resell them. - Halterio Cloud (beta, optional) is the only paid part: Cloud computers, Linux machines that keep your agents working while your own computer sleeps. Base $20/month (250 machine hours, 1 Cloud computer), Pro $50/month (700 hours, 2 Cloud computers), Max $200/month (3,000 hours, 4 Cloud computers). An hour is an hour of a 4-core, 8 GB machine. A Cloud computer stops after a few idle minutes, and a stopped computer uses no hours. The month's hours are one pool shared by all of a plan's Cloud computers. Extra hours: 100 for $10, never expire. Details and a comparison: https://halterio.com/pricing. Subscribe at https://halterio.com/account. ## Beta status Halterio is in public beta. It's ready for daily work, but it's pre-1.0: builds aren't code-signed yet, things still change between versions, and some rough edges are left. The app updates itself, so fixes arrive without a reinstall. ## How to start 1. Install at least one agent CLI and sign in, for example `claude` or `codex`. 2. Download and install Halterio (links below) and open a project folder. 3. Start a session, type the task, and pick whether it runs in a new worktree or in the folder. ## Download Version 0.4.0 (public beta), released 3 November 2026. Pre-1.0. The app updates itself after the first install.
