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.
As someone who is often creating new pages, Netlify's preview makes the review process easier. You can also use the generated URL from Netlify's preview to run an SEO audit prior to going live. This is very useful for spotting bugs or broken redirects.
Based on our record, Netlify seems to be more popular. It has been mentiond 114 times since March 2021. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
When we benchmarked this against other services, we could not find another service that could import and run even modestly complex projects in the way described above. Many platforms are excellent at running frontend applications, such as Netlify and Vercel, but we have not found any that really try to handle full-stack projects, monorepos, development environments, production environments, databases, and service... - Source: dev.to / 3 months ago

For developers building for the web, understanding these trends is increasingly important. Users are becoming more privacy-conscious and seeking alternatives to algorithmic feeds. Tools like Netlify and Vercel are making it easier than ever to deploy independent websites, while privacy-focused tools like 1Password are helping users manage their digital identities across multiple platforms. - Source: dev.to / 4 months ago
All three themes are designed for accessible deployment. You can host them for free on Netlify, GitHub Pages, Vercel, or Cloudflare Pages. The only cost is a domain name (which can be as cheap as $5/year on Porkbun). - Source: dev.to / 6 months ago
