Currai

Currai is an observability and tracing platform built for LLM applications, designed to replace tedious print statement debugging with a single, unified view. Every prompt, token, and tool call is traced end to end, so you can see exactly what your application is doing instead of guessing.

With Currai, you can monitor live production traffic and calculate costs based on the bytes your application actually processes, giving you a clear picture of spending as it happens. The platform also supports running evaluations and A/B testing different prompt versions in real time, letting you compare variants against each other before committing to a change — all without needing to spin up any local infrastructure.

Getting started is simple thanks to drop-in Python and TypeScript SDKs. Currai is also byte-compatible with Langfuse and OpenTelemetry, so integrating it into a new project or migrating an existing one is straightforward and low-friction.
