Hi HN, I made a tiny tool called YAML Validator that checks your YAML files with one Docker command — no installs, no setup, no excuses. It does: - Syntax checks - yamllint linting - checkov security scanning - All in one lightweight, zero-config container --------------------------------------------------------- How to use: docker run -v "$(pwd):/data" pooyanazad/yaml-checker Optional alias (for .bashrc / .zshrc): alias ytest='docker run -v "$(pwd):/data" pooyanazad/yaml-checker' Then simply call: ytest sample.yaml YAML powers CI/CD, configs, infra ,and…

eno [1] - A modern plaintext language w/ libraries [2] for JavaScript, Python, Ruby & soon more! We migrated a big relational research database to a file-based solution - requirements were: - Super fast and easy editability for users - Highest performance for parsing/validating >10K documents on every user change. Our trials with YAML/TOML showed us that we wanted something both faster [3][4] and easier [4], something tailored for file-based content management ... and after months of research & development it's now publicly available (under MIT license) for everyone! Last but…

Hey HN, I'm Brandon, a solo dev, and I built KubeForge - a visual editor for Kubernetes deployments that helps you build and validate YAML configs. Origin Story: Over the past couple weeks, I got fed up manually writing Kubernetes YAMLs, especially when working with nested structures like containers, env, and volumeMounts. Even small typos or misaligned fields added lost time to broken deploys. So I started hacking together a tool to visualize the structure of Kubernetes objects based on the OpenAPI schema. That prototype quickly turned into a full manifest builder. What KubeForge does: -…

Hi, this is a Python framework I have created to make my life a little easier when creating custom linting rules. Key features: - Quick to use (~20 LOC to create a functioning linter/checker) - Works with different file formats (as in the description) - Supports multiple ignore/noqa directives (per-line ignores, range ignores, whole file, rules choice during runs) - Single check can span all elements of the file or even all files - Works directly with Python's AST - Tutorials and API reference to make users life easier All in all seems to be quite functional for my private (yet)…

Hi HN I built YAML Studio, a visual editor that helps you design complex OpenAPI specs without hand-writing YAML or dealing with $ref headaches. It's a drag-and-drop, form-based tool that generates clean OpenAPI 3.0/3.1 YAML — useful for devs, PMs, and tech writers who want to collaborate on API design without needing deep spec knowledge. Why I built this: I’ve spent countless hours manually writing and debugging OpenAPI files — breaking things with a bad indent or misused $ref. Existing tools like Swagger Editor are great, but still very code-centric. I wanted something more intuitive,…

Hi HN, I'm launching DataXLator, a utility I built to solve a problem many of us face: needing quick, reliable conversion between JSON and YAML for config files (Kubernetes, Ansible, etc.) without trusting a random server with sensitive data. The core feature is that all free conversions run 100% client-side in your browser using js-yaml and browser APIs. This guarantees privacy and speed. I've also implemented real-time error reporting to help debug syntax issues instantly. While the core tool is FREE, I'm launching with a Pro subscription to fund development of high-value, server-backed…
