Powerful Features for Modern Teams
Everything you need to build, ship, and scale your AI applications
- Tracing
- Evaluation
- Prompt Hub
- Experiments
- Dashboards
- Fleet Hub
Distributed Tracing
Monitor and trace your LLM applications in real-time. Visualize request flows, identify bottlenecks, and understand the complete lifecycle of every AI interaction with OpenTelemetry-powered distributed tracing.
AI Model Evaluation
Run online/offline evals via UI (experiment with prompts/models) and via SDKs (experiment with end-to-end applications).
Prompt Management
Centrally manage, version, and deploy prompts across your applications. Experiment with different prompt variations, track performance, and iterate faster with version control for your prompts.
Experiment with your prompts and models
Experiment with your prompts and models to find the best performing ones. OpenGround is a playground for you to experiment with your prompts and models.
Real-time Monitoring
Get a unified view of all your LLM applications across different environments. Write custom SQL queries to analyze your AI telemetry data, create and resize custom widgets with flexible configurations and layouts, and visualize telemetry from any OpenTelemetry-instrumented tool.
Multi-Deployment Management
Monitor multiple deployments, compare performance metrics, and manage your entire AI fleet from a single dashboard.
Get started in minutes
Add comprehensive observability to your LLM applications with just a few lines of code. No code changes required for existing applications.
