Developer License: $49 USD (one-time) includes Python/FastAPI engine source code, Vite/React observer dashboard, zero-cost mock mode, and single-user research grant. Commercial License: $149 USD (one-time) includes everything in Developer License plus perpetual royalty-free commercial distribution,
Free: $0 for up to 3 projects and one person (never charges). Builder: $15 a month or $150 a year. Team: $36 per person a month or $360 per person a year. New accounts start on Team for 14 days free with up to 5 projects.
Key features
Decoupled tick loop with independent tick rate scheduling
SQLite WAL-mode persistence with concurrent reads and zero lock overhead
Multi-generational genealogy and asset transaction logs
Zero-token mock mode for local simulation without API costs
Python/FastAPI backend with Vite/React observer dashboard
Circadian cycles and natural mortality mechanics
Seamless LLM integration with OpenAI, Anthropic, or Ollama
Docker Compose deployment stack for Commercial License
Instant source code delivery with digital license key
Agents declare plans before writing code
Written rules automatically settle conflicting plans
Integration with Claude Code, Codex, and MCP clients
GitHub repository mirroring after each merge
Intent-based workflow instead of pull requests
Drift detection comparing code changes to declared plans
No branch names; work identified by intent number
Write rules per folder with CI files people-only
What makes it different
Turnkey engineering for complex simulations without building the loop from scratch
Zero recurring platform subscriptions with direct software licensing
No lock overhead persistence with WAL-mode SQLite for concurrent reads
Local LLM execution without incurring API costs in mock mode
Royalty-free commercial distribution rights with Commercial License
Conflicts settled before any code is written
Agents review intent goals and plans, not line-by-line diffs
Works with your existing agents without leaving GitHub
Only humans approve merges, never agents or models
