Captain AI That Plans & Executes
Like a Virtual Team

Inspired by Manus — our Captain AI decomposes any task into parallel subtasks, each worker running real code in isolated E2B Linux sandboxes. Not simulated. Not mocked. Real execution.

Captain Decomposes Tasks
Gemini Flash analyzes your goal and breaks it into 2–5 independent parallel subtasks — each solvable in isolation.
Workers Run in Real E2B Sandboxes
Each worker gets its own isolated Linux sandbox, generates code, executes it, reads output, iterates — real compute, not simulation.
SSE Real-Time Streaming
Task progress streams via Server-Sent Events. See each worker output live as it runs, with polling fallback.
Credit-Based, Transparent Pricing
Captain costs 5 credits. Each worker 3. 100 free credits on signup + 50 daily. Full transaction history.
