What it does
The Problem: Editing complex JSON data manually is a recipe for disaster. One missing comma or a mismatched bracket can break your entire production build. For developers managing large config files or product catalogs, raw text editing isn't just slow—it's risky. The Solution: JSONdata.net turns your JSON schemas into a high-performance, structured data entry dashboard. It bridges the gap between raw code and a clean, validated UI.
Free online JSON editor with schema-based forms, live validation, and table view. Edit config files, inventory data, and nested JSON safely — no syntax errors, no manual formatting.

schema-tools – Build and Edit JSON Schemas2024 · schematools.herondata.io · ▲5We built this in a day to help save some time internally and wanted to share as others might find it useful for managing structured output schemas. There’s a few other tools out there - but none had exactly what we needed! Key Features: 1. Two-Way Editing: Paste in an existing JSON schema and edit it within the UI 2. Data-Type Validations: add validations to fields 3. Local Storage & Version History: track your edits, don’t lose changes Link: https://schematools.herondata.io Source Code: https://github.com/heron-data/schema-tools

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…

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
