UpTrain
What UpTrain is
UpTrain is a free, open-source platform for evaluating and improving applications built with large language models. It is available through an API, self-hosted deployment, and a web dashboard that can run locally; the repository describes the dashboard as beta. The platform scores more than 20 preconfigured evaluations and supports custom prompt and Python evaluations. Checks include prompt injection, jailbreaks, system prompt leaks, and code leaks. UpTrain can isolate failures, identify recurring patterns, and provide root-cause analysis with resolution insights. Teams can run configuration experiments, automate regression tests after prompt, configuration, or code changes, and roll back prompt versions. It can create diverse test sets and add production edge cases to datasets. Evaluations and analysis run locally except model-grading LLM calls. The core framework uses the Apache 2.0 license and lists integrations such as OpenAI Evals, LlamaIndex, Ollama, Langfuse, Qdrant, and Chroma.
Who it suits
UpTrain suits developers, product managers, managers, and business leaders working with LLM applications. It is relevant to teams needing evaluation, safety checks, regression testing, and local analysis.
What it does well
- Free and open source
- 20+ preconfigured evaluations
- Custom prompt and Python checks
