VERDICT

Should I use Comet?

New! Track & optimize Claude Code spend across your engineering team. - comet.com

Depends. Buy if your team trains models regularly and drowns in experiment spreadsheets — academics get it free. If you run one model a quarter, TensorBoard or MLflow covers you.

Confidence

Medium. Based on 14 public sources; pricing details and independent critical reviews are thin. Security findings about Perplexity's Comet browser are a different product and were excluded.

Best for

  • ML teams running many experiments
  • Deep learning researchers on PyTorch/TensorFlow
  • Academic labs wanting free tracking
  • Teams monitoring LLM/agent API spend

Not for

  • Occasional model trainers — TensorBoard or MLflow is enough
  • Teams wanting self-hosted open-source tracking with no vendor lock-in
  • Solo hobbyists with a handful of runs
  • Non-ML projects needing general analytics or BI

Gotchas - check before you buy

Pricing opacity: only academic-free offer visible; commercial tiers likely need a sales conversation

low

Many 'Comet' search results describe Perplexity's AI browser, not this tool — vet sources carefully

Pros and cons

Pros

  • Free for academics — students, researchers, professors
  • Native support for TensorFlow, Keras, PyTorch, MXNet
  • Integrates with ZenML pipelines for MLOps workflows
  • Claimed 68% faster experiment analysis vs manual methods
  • Hosts frontier research, e.g. AI2's OLMo-2 experiments

Cons

  • Paid-tier pricing barely visible publicly; only academic-free offer surfaces
  • Name collides with Perplexity's Comet browser, muddying search and reviews
  • Shareable experiment pages require JavaScript; some views won't render otherwise

Alternatives

Compare Comet with each alternative.

  • Weights & Biases

    Category leader; richer dashboards, similar scope

  • MLflow

    Open-source and self-hosted; free but more setup

  • TensorBoard

    Free built-in visualization; fine for small projects
