How to Migrate from Helicone to OpenObserve

Mintlify's acquisition of Helicone on March 3, 2026, led to Helicone being placed in maintenance mode with its roadmap frozen and new signups closed, prompting many existing users to migrate to OpenObserve. This migration is not a mere configuration change but an architectural shift, as Helicone operates as a proxy logging requests, responses, and costs, whereas OpenObserve functions as an OpenTelemetry-native backend storing telemetry data. Users transitioning to OpenObserve need to remove Helicone's proxy and implement OpenTelemetry instrumentation, either through OpenLLMetry for ease of use or manual instrumentation for greater control. While OpenObserve offers the advantage of a unified backend for large language model (LLM) and infrastructure telemetry, allowing for efficient SQL querying and storage, it does not replicate Helicone's built-in features like caching, rate limiting, and request routing, which can be addressed by using a separate routing proxy such as LiteLLM. The migration provides a streamlined observability solution by correlating LLM data with infrastructure telemetry, although it requires users to manage telemetry and request behavior separately, offering a more flexible but distinct approach from Helicone's integrated proxy model.
