What both publish
| Fact | Langfuse | LogicGaze |
|---|---|---|
| API | The public data platform includes APIs for observations, experiments, metrics, prompts, datasets, projects, exports, and an OpenAPI specification. | The documentation describes a REST API for traces, projects, guardrail configuration, and the AI gateway proxy. |
| Evaluations | Evaluation supports LLM-as-a-Judge, heuristic or code evaluators, human review, annotation queues, and scoring of production data or experiments. | It converts production traces into test cases and supports LLM-as-Judge scoring, human review, experiment comparison, and online evaluators. |
| Integrations | Langfuse lists more than 100 integrations spanning OpenTelemetry, Python and TypeScript, model providers, agent frameworks, gateways, and developer tools. | Supported providers include OpenAI, Anthropic, Google Gemini, Azure OpenAI, Mistral, Cohere, Groq, Amazon Bedrock, DeepSeek, xAI Grok, Ollama, Together AI, Perplexity, Meta Llama, and HuggingFace. |
| SDKs | Official SDKs are Python v5 and JavaScript/TypeScript v6; other languages can use OpenTelemetry instrumentation. | LogicGaze provides native Python and TypeScript SDKs, including zero-configuration instrumentation for OpenAI and Anthropic. |
| Self-hosting | The OSS edition can be deployed with Docker Compose, Kubernetes Helm, or Terraform guides for AWS, GCP, and Azure, including offline or air-gapped installations. | The documentation says LogicGaze can be deployed on a customer's own infrastructure with Docker for full data ownership and configuration control. |
