Isee vs Codex App
OpenAI provides Codex through the ChatGPT desktop app on macOS, Windows, and Linux, with local, worktree, cloud, and remote workflows.
Isee is an app for orchestrating coding agents, with native clients on desktop, mobile, web, and the CLI. Open source (Apache-2.0).
The main difference
OpenAI provides Codex through the ChatGPT desktop and mobile apps. Using those product surfaces requires an OpenAI account, and cloud work runs on OpenAI-managed infrastructure.
Isee runs your installed Codex CLI on machines you control. It does not require a Isee account, collect telemetry, or depend on a Isee cloud service. Connect directly from desktop, mobile, web, or the CLI, or use the optional end-to-end encrypted relay.
Isee does not upload or store your code. The relay cannot read your code, messages, or agent output. You can self-host the daemon, web client, and relay, and use the same control plane with Codex, Claude Code, OpenCode, Pi, ACP agents, and custom providers.
Architecture
Isee runs an independent daemon on your laptop, workstation, VM, home lab, or cloud machine. The daemon launches your installed Codex CLI with its existing credentials and configuration. Clients connect directly or through the optional end-to-end encrypted relay.
OpenAI provides local, worktree, remote, and cloud Codex workflows through its ChatGPT product surfaces. Local and remote work use a connected host, while cloud work runs on OpenAI-managed infrastructure.
Providers
Codex App runs Codex.
Isee runs Codex too, plus Claude Code, OpenCode, and Pi natively, plus 30+ more agents through the in-app catalog including GitHub Copilot, Cursor, Gemini CLI, and Amp. Isee speaks the Agent Client Protocol, so any ACP agent works. Custom providers run any CLI agent. See all supported providers.
Application plugins
Isee plugins extend Isee itself. They can add server behavior and native client components such as workspace panels, sidebar items, composer attachments, themes, and Command Center items across desktop, browser, iOS, and Android.
Codex supports skills, MCP servers, and other agent extensions. OpenAI does not document an extension API for adding server-side behavior and native interface components to the Codex application itself.
Desktop platforms
OpenAI's desktop app and Isee are available on macOS, Windows, and Linux.
Mobile
Isee ships native iOS and Android apps with the same agent workflow as the desktop app.
ChatGPT Remote can start and continue Codex chats, approve actions, and review outputs from iOS and Android through a connected desktop host.
Worktrees and local setup
Both tools support Git worktrees for parallel work.
Codex App creates Codex-managed worktrees under $CODEX_HOME/worktrees and supports local environment setup scripts and project actions through .codex configuration.
Isee creates worktrees under $PASEO_HOME/worktrees, runs setup and teardown hooks from paseo.json, and gives each worktree its own dev server URLs like web.fix-auth.my-app.localhost so parallel services don't fight for ports.
GitHub and review
Both tools support reviewing diffs, committing, pushing, and opening pull requests from the app.
Isee also surfaces PR checks and reviews in the app, and exposes the same workflow through the CLI and MCP server.
CLI and automation
Codex has its own CLI, IDE extension, web app, automations, and SDK.
Isee's CLI controls the same daemon as the app:
paseo run --provider codex "implement OAuth"
paseo run --provider claude --worktree refactor-auth "refactor auth"
paseo run --host devbox:6767 "run the test suite"
paseo ls
paseo send <agent-id> "add tests"
paseo schedule create --cron "0 9 * * 1" "audit the codebase"
paseo run --host connects to a remote daemon. paseo schedule runs an agent on a cron. The MCP server lets other agents create worktrees, launch agents, open terminals, and send prompts.
Voice
Codex App supports voice dictation.
Isee supports dictation and realtime voice mode. Speech-to-text and text-to-speech can run locally on your device.
