What is Pairlet?
Pairlet is an open-source remote client for Claude Code and OpenAI Codex processes running on your own computer. It is not a cloud IDE or a model provider.
Does Pairlet require an account?
No Pairlet account or sign-up is required. Devices pair to a daemon identity. You still need the appropriate Anthropic or OpenAI access for the coding agent you run.
Is Pairlet free?
Pairlet is free and MIT-licensed. Agent provider subscriptions, model usage, hosting, network, or app-store charges are separate.
Does Pairlet support both Claude Code and OpenAI Codex?
Yes. You choose Claude Code or Codex for each session. A session stays bound to one backend.
Does my source code leave my computer?
The coding agent and repository stay on your computer. Session content sent to a paired client crosses the relay as end-to-end encrypted frames. The paired client and local daemon are trusted endpoints and see plaintext.
Can I self-host Pairlet?
Yes. The relay, daemon, protocol, and clients are open source. The repository includes a systemd and Caddy reference deployment for the relay.
What platforms does Pairlet support?
The client supports iOS and iPadOS, Android, macOS, Windows, and Linux. The daemon runs on the computer that hosts the coding agent; current install details are maintained in the project README and releases.
Does my computer need to stay on?
Yes. Pairlet remotely controls a coding-agent process on your computer, so that computer and its daemon must be running and reachable through the relay or local network.
Has Pairlet been independently security audited?
No. The security design and source are public, but the project's custom Noise-style end-to-end channel has not received an independent audit.
