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.

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
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

There's https://tailwindui.com/?ref=top, from the Tailwind CSS people. They come with a "HTML" mode, which I think means no JS. But if you need interactivity, on the web it has to be JS, because that's the only thing that can manipulate the DOM. The alternative would be something like a server-updated Canvas where the UI is done outside of the DOM and not in the client, but even that would need some JS shims just... - Source: Hacker News / about 2 years ago
