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.

Tailwind UI features and specs

  • Rapid Development
    Tailwind UI provides pre-designed components that help developers build interfaces quickly, reducing the time required to go from design to production.
  • Customization
    The components are built with Tailwind CSS, which allows for easy and extensive customization directly within the HTML, providing flexibility in design without needing to write custom CSS.
  • Consistency
    Using Tailwind UI ensures consistency across the application by providing a unified design language and pre-designed, reusable components.
  • Accessibility
    Components in Tailwind UI are designed with accessibility in mind, helping developers to create more inclusive and usable interfaces.
  • High-Quality Design
    The components are designed by professionals, ensuring high visual and functional quality, which can be beneficial for projects without a dedicated design team.
  • Documentation
    Tailwind UI comes with comprehensive documentation that aids developers in integrating the components effectively and understanding how to best utilize them.

Possible disadvantages of Tailwind UI

  • Cost
    Tailwind UI is a paid product, which can be a barrier for small projects or individual developers who are operating on a limited budget.
  • Learning Curve
    While Tailwind UI components are easy to use, the underlying Tailwind CSS framework can have a learning curve for those unfamiliar with utility-first CSS approaches.
  • Overhead
    Incorporating a large number of components can increase the initial bundle size, which may affect the performance unless optimized appropriately.
  • Dependency on Tailwind CSS
    Tailwind UI components are tightly coupled with Tailwind CSS, which means switching to or migrating from another CSS framework may require substantial effort.
  • Not Always Unique
    Using pre-built components might result in less unique designs, as other developers and projects using Tailwind UI can have similar looks and feels.
  • Limited Scope
    The pre-designed components cover a wide range but may not fulfill every niche use case, requiring additional custom development or design.

Questions & Answers

As answered by people managing Tailwind UI and YAMLValidator.dev.

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.

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.

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.

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.

  • Getting Tailwind CSS Running in React and Next.js (Without the Headaches)
    Tailwind UI is a commercial component library, but even the free examples teach you solid patterns for responsive design and component architecture. I learned a lot just by reading through their example code. - Source: dev.to / 11 months ago
  • Ask HN: Link to interactively learn UI/Typography design
    Studying existing component systems is a great starting point. You have to imitate and respect the systems that already exist before you can innovate on new things from scratch. I'd recommend starting by reading, building with, and imitating the most well-known frameworks for some personal projects. You can also find some good Figma projects to get started with on each of these. https://tailwindui.com/. - Source: Hacker News / almost 2 years ago
