Continuum is a control surface for coding agents. It splits cleanly in two:
  • Hosts run the agents. A host has your code on disk, your provider CLIs installed, and a local daemon that supervises every session. That’s the macOS app, the Windows and Linux desktop apps, the continuum CLI, a VPS, a Tailscale box, or a machine Continuum provisions for you.
  • Remotes steer them. iPhone, Apple Watch, Android, and the web app hold no code and no provider credentials — they connect to a host and drive it.
One machine can be both: install the Mac or desktop app and it is a host you’re already sitting at. Everything speaks the same wire protocol, so a session you start in a browser tab is the same session your Watch can approve.

​
The three jobs

  1. Run and control coding-agent sessions. Claude Code, Codex, Antigravity/Gemini, Cursor, Grok, OpenCode-connected models (OpenRouter, Z.ai Coding), and Continuum’s own hosted models — in isolated git worktrees, with plan review, diffs, PRs, and terminals. Pick Auto instead of a model and Continuum routes the work across your connected providers itself. This is the Code tab, and it’s the center of the product.
  2. Show live quota and spend. Session windows, weekly caps, reset timers, and historical $ / token analytics by provider, day, and repo. This is the Usage tab.
  3. Follow you off the desk. Sign in on your phone, watch, or a browser and every session is there: approve a plan, send a follow-up, star the better answer, merge a PR. End-to-end encrypted between your devices.
Continuum shipped a Chat tab and a Cowork tab earlier in its life. Both are hidden by default as of 2026-07-30 while the product focuses on Code. The docs for those surfaces are still here — see Chat — but you won’t find the tabs in a current build.

​
What it costs

Every client is free: Mac, Windows, Linux, CLI, iPhone, Watch, Android, web. You bring the provider subscriptions you already pay for, and Continuum drives each provider through its own official CLI, so the work lands on your flat-rate subscription rather than a metered API key. You can sign in more than one account per provider and run them side by side — see multi-account. If you’d rather not bring keys at all, Continuum-hosted inference is the one paid add-on: a monthly plan with a weekly inference budget, starting at $25/mo. A set of free hosted models is included on every plan — the model picker’s Continuum rail splits them into Included in Free and frontier models — so you can get a real answer before connecting anything. See hosted inference.

​
The shape of the thing

A host runs an HTTP/WebSocket daemon (default port 21731, WebSocket on the next port up) and the provider CLIs as child processes. Remotes connect to it over an end-to-end encrypted relay — the relay forwards sealed bytes and cannot read them.
Devices find each other by account: sign in with the same email everywhere and your hosts show up in the device list, no QR codes — see pairing and remote devices. When you want a wall of agents instead of one, the Code sidebar’s Spawn button opens a grid of interactive CLI terminals — see spawn mode.
Continuum is local-first. Code, transcripts, analytics, and provider credentials live on your hosts; remotes hold a token and a view. The privacy doc enumerates exactly what can leave your machines and why.

Quickstart

Install on any platform, light up your first gauge, and run your first session in five minutes.

Installation

Per-platform requirements, installers, and how each client updates itself.

Connect your devices

Sign in with the same email on each device and approve it once. No QR code.

Windows & Linux desktop

The same workbench outside Apple’s world, with its own bundled daemon.

Web app

The full control plane in a browser tab — nothing to install.

Terminal CLI

continuum drives the same sessions from a shell, a script, or CI.

The Code tab

Sessions, worktrees, plans, diffs, and PRs — where the work happens.

Providers

What Continuum needs from each CLI, and what lights up when it finds it.
