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.

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.

Before working on more challengin but interesting serializer like CBOR or Protocol Buffer, let take a moment to learn how use JSON in Dart. - Source: dev.to / about 2 months ago
a BinaryDataReceived object is returned when the server is sending binary message (e.g. protobuf, CBOR). - Source: dev.to / 2 months ago
Protocol Buffers are Google's language-neutral, platform-neutral mechanism for serializing structured data. They're what powers communication between services at Google, Netflix, and most high-scale tech companies. Unlike JSON (text-based), protobuf is a binary format โ compact, fast to serialize/deserialize, and schema-enforced. - Source: dev.to / 4 months ago
Protocol buffers, aka protobufs, are an amazing tool for making a build engineer's days a living nightmare. First we must note that there are at least two competing protobuf compilers in the JVM world: Google's protoc and Square's Wire. I happen to work at a company that uses both. I don't think I hate myself, but maybe God does. These compilers generate code (Java or Kotlin) from the protobuf format that are... - Source: dev.to / 9 months ago
The most comprehensive support for JS, along with future support for TS, comes from the TypeScript compiler. However, it's written in a different language, so we must transfer the AST via gRPC. To maximize performance, we use protobuf. - Source: dev.to / 8 months ago
