What it does
StructKit is a fast, no-signup JSON toolkit for developers, SEOs, analysts, and technical operators. It helps users format, validate, and inspect JSON directly in the browser without uploading data or dealing with bloated dashboards. The goal is simple: practical data tools that load fast, work instantly, and stay focused on the job. Current tools include a JSON Formatter and JSON Validator, with more focused JSON utilities coming next.
Fast JSON tools for formatting, validation, diffing, conversion, querying, and debugging.
Format, validate, diff, convert, and query JSON in one place. Open the tool you need, paste the payload, and get the result immediately. { "user": { "id": 1042, "name": "Alex Chen", "admin": false }, "tokens": [ "eyJhbGci...", "eyJhbGci..." ], "session": null } Tools Open the tool you need and stay in the flow. No setup screens, no detours, just the JSON task in front of you. Compare two JSON versions side by side and spot changed keys, values, arrays, and nesting without manually scanning the whole payload. Beautify raw JSON with readable indentation. One click to copy the clean output. Check syntax and surface parse errors. Shows the exact line and character where it breaks. Validate JSON…from structkit.dev

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
