  • Agent Simulations
    Evals check the final output. Simulations check everything in between: was the right tool called, and did anything break in the middle of a multi-turn conversation?
  • Evaluations
    Define quality metrics, run them offline in CI or live on production traffic, and catch regressions before they ship. Bring your own datasets, tools, and pandas - add a few lines and start tracking.
  • Observability
    OpenTelemetry-native tracing for LLM apps. Instrument once and inspect every LLM call, tool call, and RAG retrieval across dev, staging, and production - with cost and latency on every span.
  • Open Source
    GStack is open source, allowing developers to review, modify, and contribute to the project. This promotes transparency and community collaboration.
  • Versatile
    GStack provides a modern stack that can be used for a variety of applications, offering flexibility to developers in building different types of projects.

    Users unfamiliar with the technologies involved may face a steep learning curve, needing to understand each component of the stack to utilize it fully.
