Is Opik actively maintained?
Development is ongoing. The repository recorded 3910 commits over the same window, and the last three months alone account for 940 of them.
The most recent tagged release, 2.2.81, shipped within the last month — a current, installable version exists today.
Note that Opik depends on a third-party service to work fully. It is self-hosted, but not self-contained: if that external service changes its terms or disappears, your instance is affected.
Of the 16 projects we track in Software Development - API Management, Opik ranks #2 by health score — in the top quarter of its category.
What Opik actually does
Opik is a self-hosted platform designed to evaluate, test, and monitor large language model applications. It provides observability tools to help you calibrate model outputs and track performance throughout both the development and production lifecycles.
Best fit: Development teams building language model applications who need internal tooling to test outputs, track behaviour, and maintain quality control across environments.
Worth knowing: The platform introduces significant architectural complexity and storage requirements typical of telemetry systems, meaning you will need to monitor resource consumption carefully in production.
Deployment notes
As a Docker-based application built with Python, you will typically need to configure persistent volumes for data storage, manage environment variables for configuration, and place the container behind a reverse proxy to handle TLS termination.
