Mirascope
An open-source LLM SDK for calling multiple model providers, defining tools and returning structured outputs from application code.
About Mirascope
Application developers need a consistent way to connect model calls, tools and structured responses across providers.
Who it’s for
- Developers building LLM applications
- Teams integrating typed model outputs and tool calls
When to consider it
Consider Mirascope when you want provider-agnostic model calls and tool workflows inside your own application code.
Tradeoffs & limitations
- MIT licensed; you supply your own model-provider API keys. Mirascope Cloud was discontinued in v2.4.0, so tracing needs a separate OpenTelemetry backend.
