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 Trello 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.

Trello Reviews

  1. Trello: Simple, Visual, and Surprisingly Powerful

    Trello makes project management feel effortless. Its board-and-card setup is intuitive, letting you organize tasks and track progress with just a glance. The free plan is generous, and Power-Ups add extra muscle when your projects grow. While itโ€™s not loaded with advanced features like some competitors, its simplicity and flexibility make it a go-to tool for teams and individuals alike.

    ๐Ÿ Competitors: Jira
    ๐Ÿ‘ Pros:    Super easy to use|Great for collaboration|Flexible with power-ups
    ๐Ÿ‘Ž Cons:    Limited advanced features|Can get cluttered|Some features locked behind paid plans
  2. A handy tool for planning

    Trello excels as a task planning tool, and I appreciate its user-friendly interface, especially when using it on a smartphone. Its mobile app is incredibly convenient, allowing me to stay organized and connected on the go. I appreciate how it streamlines collaboration without unnecessary complexities.

  3. Been using it for over 5 years! Super effective!

    Incorporating Trello into my daily workflow has been a game-changer. It is an incredibly intuitive and versatile tool that has significantly boosted my productivity. What I particularly love about Trello is the visual aspect of its interface - the board and card system makes it easy to visualize my tasks and progress. The ability to create different boards for different projects or areas of work helps to keep everything organized and easy to manage. Adding, moving, and categorizing tasks are just a drag-and-drop away, making it straightforward and efficient. The flexibility to customize each card with due dates, labels, checklists, attachments, and even members has been beneficial in tracking the status of various tasks and deadlines.

    he collaborative features are another huge plus. Sharing boards and tasks with colleagues, and being able to comment directly on cards, makes team projects and communication a breeze. On the go, I have found the Trello mobile app to be just as user-friendly and functional as the desktop version, allowing me to stay on top of my tasks no matter where I am. Overall, Trello has proved to be an invaluable tool in managing my daily tasks and enhancing productivity. I highly recommend it to anyone looking to streamline their workflow.
