A fast, minimal and offline-friendly web playground
I built a web-based HTML/CSS/JS editor focused on speed, simplicity, and offline access. No bloat — just open and start coding. What makes it different: Live Preview – Edit HTML, CSS, and JS side-by-side with instant feedback. Offline support – Works without internet. You can even install it as a PWA and use it like a native app. No Login Required – Just visit, code, and preview. Login only if you want to save/share. Savable & Shareable Links – Save scripts in the cloud and get shareable links. Customizable Editor – Themes, fonts, auto-format on save, layout tweaks, line…

In plain words
A web-based HTML, CSS, and JavaScript editor designed for speed and simplicity, with offline functionality and instant live preview. It requires no login to start coding and works as a progressive web app on any device. Users can save and share their work via cloud links, customize the editor with themes and fonts, and export projects as ZIP files. The tool is intended for quick prototyping, teaching, and building small applications, with features like hotkey support and automatic formatting.

An open-source, collaborative, WYSIWYG Markdown editor2023 · editor.vrite.io · ▲460Inspired by the design and UI/UX of apps like Notion, and utility of open-source apps like StackEdit, I decided to create a minimalistic, local-only WYSIWYG Markdown editor. Some features worth highlighting: - Monaco editor and Prettier integration for code snippets - Tables (apparently the holy grail of WYSIWYG editing) - Embeds (for CodePen, CodeSandbox and YouTube, most useful for HTML or JSON exports) - Accepts Markdown paste-in, and "exports"/generates HTML, Markdown and JSON outputs - Collaboration (with real-time awareness and initial commenting system, available only when…
- BBBrowser-based web design platform with code import and CSS filters2024 · demo.gocodestudio.com · ▲91
I built a web-based app for building websites. The main unique features are: 1. The ability to copy and paste any HTML and CSS into the editor with no limits. I was never able to find another app that could do this without some form of limitation. 2. CSS filtering, which means you can click on an element to view and edit the CSS selectors and rules that apply to that element alone. In many cases I've found CSS naming conventions like BEM to become irritating at certain scales, so this is an alternative solution. This part of the app needs some more development work but the concept is there.…
GrapesJS2016 · grapesjs.com · ▲163I’ve been working with @artf (creator of GrapesJS) on Grapes Studio, an HTML-first editor with an LLM assistant on top of GrapesJS. We’re approaching this differently than the new wave of AI app/site builders which are typically generating full React applications, which we think is overkill for simple websites. From talking to people using these tools, we’ve seen a lot of issues with build errors and overly complicated pages. With our approach you can: - Edit visually via the no-code editor (drag/drop) or ask the LLM to make scoped changes (like “add a section” or “add a new…

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…

Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…
