Comet

Comet is an enterprise AI/ML developer platform used by over 150,000 developers and organizations including Netflix, Uber, and Autodesk. Its flagship open-source product, Opik, is an LLM observability, evaluation, and optimization suite for building, testing, and monitoring generative AI applications, RAG systems, and agentic workflows — with tracing, automated LLM-as-a-judge and heuristic evaluations, prompt management and optimization, and production dashboards. Comet also provides classic MLOps tooling for experiment management, model registry, artifacts, and production monitoring. Opik exposes a full REST API, Python and TypeScript SDKs, a CLI, and an official Model Context Protocol (MCP) server, and runs on Comet Cloud, self-hosted (Docker/Kubernetes), or enterprise deployments. Sector: ai-enterprise-software.

agent aware

Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.

Kin Score

API Evangelist profiles Comet the way a machine reads it — 46 machine-readable artifacts across 42 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.

Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Comet scores 53.4/100 (developing), with a separate agent-readiness read of 34/100 (agent aware). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.

Kin Score

This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Comet

Each block below is one kind of artifact we hold for Comet. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.

APIs 42

Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.

MCP Servers 1

Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

Security Posture 3

Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
