Overview
Comet ML (branded as Comet) is a New York-based AI developer platform founded in 2017 by Gideon Mendels and Nimrod Lahav. It offers two flagship product families: an MLOps platform for ML experiment tracking, model registry, dataset management, and production monitoring; and Opik, an open-source LLM observability and evaluation platform launched in September 2024. Trusted by over 150,000 developers and 10,000+ teams—including Netflix, Uber, Etsy, Zappos, and NatWest—Comet supports the full AI development lifecycle. The Opik GitHub repository has surpassed 19,000 stars. The company has raised approximately $70M in total funding, with a $50M Series B led by OpenView in November 2021. Deployments span cloud-hosted, self-hosted, and on-premises options with enterprise-grade compliance.
Comet is an end-to-end AI developer platform with two core product families: (1) a MLOps platform covering experiment tracking, model registry, dataset versioning, and production monitoring for teams building and training ML models; and (2) Opik, a truly open-source LLM observability and evaluation platform for tracing, testing, optimizing, and monitoring LLM applications and agentic workflows—available via self-hosted OSS, managed cloud, or enterprise deployment.

Alternatives in MLOps & Experiment Tracking5
Comet positions itself as the only end-to-end AI developer platform covering both traditional MLOps (experiment tracking, model registry, dataset management, production monitoring) and GenAI/LLM observability via its open-source Opik platform.
- It differentiates on infrastructure-agnosticism (cloud, self-hosted, on-prem), true open-source LLM evaluation, and breadth of integrations across the full AI lifecycle—contrasting with point solutions that cover only experiment tracking or only LLM tracing.
Reviews
Praised
- Easy integration with major ML frameworks (PyTorch, TensorFlow, Scikit-learn, Keras)
- Intuitive UI and dashboard visualizations
- Minimal setup and boilerplate code required
- Responsive Slack customer support
- Experiment comparison and reproducibility
- Free tier accessible for individuals and academics
- Centralized team collaboration on ML experiments
Criticized
- High enterprise license costs
- File upload size limitations causing errors
- Inconsistencies between UI features and Python SDK
- Difficult to manage large numbers of experiment trails
- Learning curve for new users
- Documentation could be more polished
- Custom view settings can become disorganized
G2 reviewers (4.3/5, 12 reviews) and Capterra/Software Advice users praise Comet for easy integration with major ML frameworks, an intuitive dashboard, strong visualization without boilerplate code, and responsive customer support via Slack. Negative themes include high enterprise licensing costs that have led some businesses to consider switching, file upload size limitations causing errors, occasional UI/SDK inconsistencies in the model registry, and difficulty organizing large numbers of experiment trails. Gartner Peer Insights reviewers note that Comet manages the ML lifecycle from training through production with in-depth analytics. Compared to Weights & Biases on G2, reviewers favor W&B on product support quality and roadmap direction.
Pricing
Opik (LLM observability): Free Open Source (self-hosted, unlimited spans); Free Cloud (up to 10 members, 25k spans/month, 60-day retention); Pro Cloud at $19/month (up to 50 members, 100k spans, additional spans at $5/100k); Enterprise at custom pricing (unlimited members, custom spans, flexible deployment, SSO, SLAs). MLOps Platform: Free (1 user, fair usage, 100GB storage); Pro at $19/user/month (up to 10 users, 1,500 training hours, 500GB storage); Enterprise at custom pricing (unlimited users, unlimited training hours, production monitoring, flexible deployment, SSO). Free Pro plan available for verified academic users across both products.
Limitations
- Enterprise licensing costs cited as prohibitively high by some teams.
- File upload size limits have caused errors and repeated upload attempts.
- Occasional inconsistencies between the UI and Python SDK, particularly around the model registry.
- Managing a large number of experiment trials can become disorganized.
- Learning curve and documentation quality noted as needing improvement by some reviewers.
- G2 reviewer base is small (12 reviews), limiting public social proof compared to alternatives like Weights & Biases (44 reviews) or Databricks (756 reviews).
