Best for Teams with EU data-residency or GDPR requirements who want self-hosted or Europe-hosted LLM observability. Teams that want open-source tracing they can self-host for free and later scale onto a managed cloud plan. Teams that want low-friction, proxy-based logging of LLM API traffic without instrumenting application code deeply. Teams that want prompts version-controlled and tested outside of application code, with logging tied to each version.
