The first public release of the Traycer Host, the local runtime that powers Traycer. The Host runs the coding agents, terminals, and Tasks behind Traycer Desktop, entirely on your machine.

You do not install the Host directly. The Traycer CLI, bundled with Traycer Desktop, downloads the correct build for your platform, verifies its signature, installs it as a managed background service, and keeps it running and up to date.

What it does

  • Runs your chosen AI coding agents directly on the repositories you are working in.
  • Stores Tasks, conversations, plans, and history in a local SQLite database.
  • Manages terminals, files, and git worktrees.
  • Exposes a versioned protocol that Traycer Desktop connects to.

It registers with your operating system's service manager (launchd on macOS, systemd user on Linux), so it starts with your session and is supervised automatically.

Agents and models

The Host runs several coding-agent backends behind one surface, selectable per Task:

  • Claude (Claude Code), via the Anthropic Claude Agent SDK.
  • OpenAI Codex, with selectable reasoning depth and an optional Fast service tier.
  • Cursor, via the Cursor SDK, configured with a Cursor API key.
  • OpenCode, via the OpenCode SDK.
  • Traycer Inference, Traycer's hosted inference service.

Provider credentials and API keys come from your provider settings. The Host does not log secrets or source code.

Skills

The Host ships Traycer's structured skills: the workflows for drafting a Task brief, producing a technical plan, breaking work down, executing step by step, and reviewing changes. Skills are versioned and integrity-checked.

Platforms

The Host is delivered as a signed, single-file runtime per platform, with no separate Node or Bun installation required:

  • macOS (Apple Silicon and Intel)
  • Linux (x64)

The CLI resolves versions from a rolling registry manifest published alongside these releases. For each platform the manifest carries a download URL, a SHA-256 checksum, and a minisign signature, and the CLI verifies both the checksum and the signature before installing.

Notes

The companion host manifest release holds the registry (versions.json) the CLI reads to discover and verify host versions; it is infrastructure, not a download. The Host is provisioned and supervised by the Traycer CLI, so no manual install is needed. Documentation is at docs.traycer.ai. Traycer is open source under the Apache-2.0 license at github.com/traycerai/traycer.
