YAML Validator is a free, privacy-first tool for validating, formatting, and viewing YAML files โ€” available as a Chrome extension and a website.

What it does

  • Syntax validation โ€” catch indentation errors, duplicate keys, and malformed YAML instantly
  • Schema validation โ€” validate against 11+ real-world schemas with auto-detection:
    • Kubernetes, Docker Compose, Helm Chart
    • GitHub Actions, GitLab CI, CircleCI, Azure Pipelines, Bitbucket Pipelines
    • Ansible, OpenAPI 3.0, Swagger 2.0
  • Multi-document support โ€” validate files with multiple YAML documents separated by ---
  • Smart error reporting โ€” highlights the exact line, shows a gutter marker, and scrolls to the error
  • GitHub integration โ€” adds collapsible code blocks to YAML files on GitHub, making large configs easier to navigate

How it works

Paste or type YAML into the editor. YAML Validator auto-detects the schema (e.g., spots apiVersion + kind and picks Kubernetes) and validates both syntax and structure in one click. If the detected schema doesn't match, it suggests the right one with a single-click switch.

Privacy & performance

Everything runs client-side โ€” your files never leave your machine. No accounts, no server processing, no data collection. Works offline, loads instantly.

Built for DevOps workflows

Whether you're writing Kubernetes manifests, debugging a CI pipeline, or reviewing a Helm chart on GitHub โ€” YAML Validator catches errors before they reach production. The Chrome extension currently has around 800 users worldwide.

Available in 54 languages.

Questions & Answers

As answered by people managing YAMLValidator.dev and Userparser.

What makes your product unique?

YAMLValidator.dev's answer

It validates YAML against real schemas โ€” generic YAML, Kubernetes, Docker Compose, GitHub Actions, GitLab CI, Helm, OpenAPI, and more โ€” 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.

Userparser's answer:

Helping developers to parser user agent and ip look up at the same time.

Why should a person choose your product over its competitors?

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 โ€” install and go.

Userparser's answer:

Using a single API call, the developer can get his users device informations and ip address informations at the same time.

How would you describe the primary audience of your product?

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.

Userparser's answer:

Anyone who wants to see his/her users parsed device and ip data, especially Web developers.

What's the story behind your product?

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 โ€” directly in the browser, with zero setup.

Which are the primary technologies used for building your product?

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

Who are some of the biggest customers of your product?

YAMLValidator.dev's answer

YAML Validator is a free, open-use tool โ€” 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.
