Werf

Werf is an open-source CNCF sandbox project providing a complete GitOps-based CI/CD solution for Kubernetes. It implements the full application delivery lifecycle — building images, managing dependencies, deploying Helm charts, and cleaning up container registries — using Git as the single source of truth (Giterminism). Werf integrates natively with all major CI systems, Buildah, Helm, and Kubernetes.

More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.

Kin Score

API Evangelist profiles Werf the way a machine reads it — 20 machine-readable artifacts, 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 — Werf scores 15.6/100 (emerging), with a separate agent-readiness read of 0/100 (human only). 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.

Features 7

The notable capabilities this provider advertises, captured as structured features so they can be searched and compared instead of read one landing page at a time.

Notable capabilities this provider offers.

Giterminism

Uses Git as the single source of truth, ensuring all CI/CD configurations are reproducible and auditable from version control.

Incremental Builds

Rebuilds only modified components and reuses existing container registry layers, dramatically reducing build times.

Kubernetes Deployment

Manages Helm chart deployments to Kubernetes with built-in rollback, planning, and drift detection (werf converge, werf plan, werf rollback).

Container Registry Cleanup

Automatically cleans up stale images from container registries using Git history-aware policies (werf cleanup, werf purge).

Helm Integration

Full Helm chart management including rendering, linting, bundling, and deploying with werf helm command suite.

Multi-CI Support

Native integration with GitHub Actions, GitLab CI, CircleCI, Jenkins, and other CI systems via werf ci-env.

Secure Software Delivery

TRDL component provides TUF-based secure software update distribution with GPG signature verification.

Security Posture 1

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.
