Opik

Track, evaluate, and improve your LLM experiments

Freemium

Opik is Comet's open-source LLM evaluation and observability platform that provides comprehensive tracing, evaluation, and monitoring for LLM applications in development and production. It captures detailed traces of every LLM call, evaluation metrics, and user feedback — enabling teams to systematically measure quality, catch regressions, and improve AI application performance over time. AI engineering teams building production LLM applications use Opik to implement rigorous quality assurance practices — moving from ad hoc testing to systematic, reproducible evaluation workflows that ensure consistent, reliable AI behavior.

What is Opik?

Opik is a AI-assisted development tool in the Developer Tools category, listed on Nextool.ai. It is designed to help you write, review and ship code more efficiently, so you can spend less time on manual, repetitive work and more time on the results that matter. Opik offers a free plan with paid upgrades and runs on the web, making it accessible without heavy setup. Nextool.ai tracks more than 10,000 AI tools, so you can compare Opik against similar Developer Tools options — on quality, integrations, privacy and price — before you commit to one.

Getting Started with Opik

Getting started with Opik is straightforward. First, open the Opik website and create an account or start a trial — the free plan lets you try it before paying. Next, give Opik a clear input — the prompt, file or data that describes what you want to write, review and ship code more efficiently. Review the AI-generated output, refine your input if the result isn't quite right, and export or save the version you're happy with. If Opik doesn't fit your workflow, compare it with other Developer Tools tools on Nextool.ai before deciding.

Tips for Getting the Most Out of Opik

A few tips help you get more out of Opik and other Developer Tools tools:

Be specific in your input — the clearer your prompt or data, the better Opik's results.
Treat the first output as a draft: review and refine rather than accepting it as-is.
Compare Opik with a couple of alternatives on a real task before standardising on it.
Check the pricing tiers and usage limits against your expected volume so costs stay predictable.

How to Choose a Developer Tools Tool Like Opik

Language, framework and IDE support
Code quality and how often suggestions need correction
Privacy of your source code and training-data policy
Context window and repository-awareness
Team and self-hosting options
Per-seat pricing against team size
