Keep the prompts behind your AI apps and agents out of your code. Version them, test them against real models, and choose which version each environment uses — for Atmispace products and your own applications alike.

What's inside
Prompts you can trust in production
Treat prompts like releases: versioned, tested, and rolled out per environment, with a record of who changed what.
Environment status
Set which version Development, Staging, and Production use, and roll back in one step. Production changes need an admin.
Multi-provider playground
Run any version against OpenAI, Anthropic, Gemini, Azure OpenAI, AWS Bedrock, Groq, OpenRouter, or self-hosted Ollama, and check output against your JSON schema.
Encrypted credentials
Provider keys and credential files are encrypted at rest. Your team can use them in the playground without ever seeing them.
Runtime API & Python SDK
Any app, on Atmispace or not, fetches the version for its environment by stable key, with scoped service tokens and caching.
Audit & analytics
Every change is recorded. See run success rates, latency, and token usage as reported by each provider.
