As answered by people managing YAMLValidator.dev and Creatopy.
YAMLValidator.dev's answer
It validates YAML against real schemas — generic YAML, Kubernetes, Docker Compose, GitHub Actions, GitLab CI, Helm, OpenAPI, and more — not just syntax checking. Everything runs client-side, so your config files never leave your machine. It works both as a Chrome extension (with GitHub integration for collapsible code blocks) and as a standalone website.
YAMLValidator.dev's answer
DevOps engineers, SREs, and backend developers who work with Kubernetes manifests, Docker Compose files, CI/CD pipelines (GitHub Actions, GitLab CI, CircleCI, Azure Pipelines), Helm charts, and OpenAPI specs. Anyone who edits YAML config files and wants instant validation without leaving the browser.
YAMLValidator.dev's answer
I am software engineer and extension(and lately site) was made out of frustration with debugging YAML indentation errors in CircleCI schemes and Kubernetes deployments. A misplaced space in a YAML file can break an entire deployment, and generic text editors don't catch schema-level mistakes. YAML Validator was built to catch those errors before they reach production — directly in the browser, with zero setup.
YAMLValidator.dev's answer
JavaScript/TypeScript, CodeMirror (editor), js-yaml (parsing), Ajv (JSON Schema validation), Lit (web components), and Tailwind CSS. Built as a Chrome Extension (Manifest V3) with Vite as the bundler. Schemas are pre-compiled at build time for performance and CSP compliance
YAMLValidator.dev's answer
YAML Validator is a free, open-use tool — it doesn't track users or require accounts. It's used by individual developers and teams working with Kubernetes, Docker, and CI/CD pipelines. As a privacy-first browser tool, there's no customer list by design. The browser extension currently has around 800 users worldwide.
YAMLValidator.dev's answer
There's simply no other Chrome extension that does this. Most online YAML tools are web-only, require an internet connection, and only check syntax. YAML Validator runs entirely offline, validates against 11+ schemas with auto-detection (Kubernetes, Docker Compose, GitHub Actions, and more), and enriches GitHub with collapsible code blocks for YAML files. It's fast, private, and requires zero setup — install and go.
