YAML Validator is a free, privacy-first tool for validating, formatting, and viewing YAML files โ available as a Chrome extension and a website.
---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.
Everything runs client-side โ your files never leave your machine. No accounts, no server processing, no data collection. Works offline, loads instantly.
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.

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.
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 โ 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 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.
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.

This is a static site generated with hugo with the PaperMod theme. I wanted an easy to use static site generator. I considered Jekyll And believe it to be a good choice for static sites. There seemed to be slightly more themes I liked with Hugo so I went with that. That's a pretty superficial choice but I also don't plan on hacking on the Site generation itself so I was agnostic to the Go versus Ruby choice. - Source: dev.to / 4 months ago
First of all, I modified my publishing programs to keep a (local) copy of each link published modulePublicationCache and then I thought about using it for my linkblog. I like very much jekyll for a blog and I requested to some AIs (mainly Qwen and Gemini) to help me to develop a blog based on the links I has posted the previous day, prepare a list with them, and prepare a Jekyll post. I also requested to set up a... - Source: dev.to / 5 months ago
I started this blog on WordPress. After several years, I decided to migrate to Jekyll. I have been happy with Jekyll so far. It's based on Ruby, and though I'm no Ruby developer, I was able to create a few plugins. - Source: dev.to / 5 months ago
So, I created โ๏ธ Meddler, a command-line tool and website that will take the .ZIP of your export that Medium gives you and turn it into clean, portable Markdown formats for Jekyll, Hugo, Eleventy, or Astro.js. - Source: dev.to / 5 months ago
After writing your posts in Markdown you can then display them however you'd like on your site through the built in Postwave Ruby client. This is where Postwave differs from static blog engines like Jekyll or Hugo which take the Markdown posts and generate a site for you. - Source: dev.to / 10 months ago
