DevNode.studio, 100% local dev tools to make back end work faster
Every tool here exists in browser DevTools or CyberChef with more features.

Every utility is a self-contained HTML file and the dashboard surfaces per-app storage with export/import and global snapshot controls — a small but thoughtful UX touch that makes local-first tools usable. Not novel in concept, but the unified data management and offline focus give it practical value for anyone who wants portable, no-dependency utilities.
Power users, developers, and privacy-minded people who want lightweight, portable web utilities that run without a backend
Every tool here exists in browser DevTools or CyberChef with more features.
700 tools in a static site, but CyberChef and browser DevTools already do this.
Everything important runs in the browser: JSON formatters, a JWT debugger explicitly marked 100% client-side, and a new Database Design Studio that turns SQL/Prisma schemas into draggable ER diagrams you can export as PNG. The product’s hook is convenience plus privacy — a single place to grab many small tools without sending snippets to a server. It’s useful and nicely designed, but the core idea is a well-curated bundle rather than a novel technical breakthrough.
Nice, no-friction collection — everything runs in the browser with zero signup and a clear grid of tools like JSON formatter, regex tester, JWT decoder and timestamp converter. Useful for quick one-off tasks and privacy-minded users, but there’s nothing here that CyberChef, DevTools extensions, or dozens of other static tool bundles don’t already do better (no chaining, no advanced features, just standalone widgets).
Site returns 502 error on launch day, and the tools are already in browser DevTools.
Yet another client-side image toolkit in a sea of remove.bg and TinyPNG clones.
