Fly.io

Fly.io Machines via REST API and flyctl CLI. Fly.io

Architecture

The Fly.io provider is implemented in TypeScript (Bun runtime). Each .sh agent script is a thin shim that ensures bun is installed, downloads the TS sources if running via bash <(curl ...), and delegates to main.ts.

fly/
  main.ts               # Orchestrator: auth → provision → install → launch
  lib/
    fly.ts              # Core provider: API client, auth, orgs, provisioning
    agents.ts           # Agent configs (all 6) + shared install/config helpers
    oauth.ts            # OpenRouter OAuth flow (Bun.serve), key validation
    ui.ts               # Logging (ANSI), prompts (readline), browser open
  {agent}.sh            # Thin bash shim → bun run main.ts {agent}

No external dependencies — all modules use built-in Bun/Node APIs only. The fly/ directory has no package.json.
