456code is my personal agent orchestration platform, derived from T3 Code. I'm building it around directing agents on furnace from my Mac desktop app, native iPhone app, or browser over a private network or tailnet. Local Mac hosting is an explicit option; iPad support follows useful upstream work.
Guiding principles define product scope, privacy requirements, provider priorities, and how regular T3 updates are evaluated. They describe the intended product; the current application still contains upstream behavior that needs separate implementation work.
There are no published releases, installers, or store apps. Desktop builds are staged on each host from origin/main and installed through the app's update pill; the iPhone app is built locally. See local packaging and staged updates.
Install and authenticate at least one provider on the host before starting a thread:
- Codex: install Codex CLI and run
codex login - Claude: install Claude Code and run
claude auth login - Cursor: install Cursor CLI and run
agent login - Grok Build: install Grok Build CLI and run
grok login - OpenCode: install OpenCode and run
opencode auth login - Antigravity: enable it in Settings, then use Install Antigravity and Sign in with Google. No CLI is required.
