Tools from Guardrails AI
- Snowglobe
Simulate diverse conversations to evaluate AI agents
Apps- Web ↗
Sign in or create an account to create chatbot apps and launch simulations in the dashboard. API keys are generated at snowglobe.so/app/keys.
Extensions- Claude Code ↗
Optional. The snowglobe-skills plugin automates install, auth, scaffolding and testing of the chatbot connection from Claude Code. It needs a Snowglobe account.
Developer access- Command line ↗
Install the Python package 'snowglobe' (Python 3.9+; macOS, Linux or Windows). Authenticate with a browser login or API key, then connect your chatbot to a simulation. The docs show both the 'snowglobe' and 'snowglobe-connect' command names.
- SDK / library (Python) ↗
Install 'snowglobe-sdk' (Python 3.11+). It gives programmatic CRUD control of Agents and Simulations through the Snowglobe API. Use the CLI package instead to connect a chatbot.
- SDK / library (TypeScript) ↗
Install '@guardrails-ai/snowglobe-sdk' (Node 20+ or Bun) for programmatic control of Agents and Simulations.

- Command line ↗
The guardrails CLI is installed with the Python package. Commands include guardrails configure, create and start. Needs Python and pip.
- API (self-hosted Guardrails Server REST API) ↗
This is self-hosted, not a managed cloud API. Install guardrails-ai[api], define guards in config.py, then run guardrails start. The REST API is exposed by that server.
