  • Instant disposable environments. Spin up isolated dev environments in seconds that are automatically destroyed when done.
  • Git repository loading. Clone and work with any Git repo directly inside the sandbox.
  • Secure port and service exposure. Expose ports and services safely without exposing your host network.
  • Browser-based VS Code. Launch a full VS Code instance in the browser from within the sandbox.
  • Reproducible environment sharing. Create shareable links that reproduce the exact sandbox state for collaborators.

WorldSeed features

  • YAML-based world definition. Define spaces, characters, goals, secrets and perception rules in a single YAML file.
  • Deterministic rule engine. Computable actions (movement, items, visibility) are resolved instantly by the engine.
  • LLM Dungeon Master. Uncertain outcomes are judged by an LLM that returns structured effects.
  • Information asymmetry. Each agent only sees what the rules allow, enabling secret-keeping and deception.
  • Event-sourced replay log. All ticks are logged for replayable analysis of emergent behavior.
  • Language-agnostic runtime. Supports agents written in Python, TypeScript, OpenClaw, Codex subagents, etc.
  • Interactive dashboard. Watch, intervene, or play as a character via a web UI with replay capabilities.
  • Open-source MIT license. Free to use, modify, and extend without commercial restrictions.
