24 alternatives to Instant HTML Preview Bookmarklet
Hey HN, I recently found myself needing a quick way to preview HTML and SVG code without having to copy it into an IDE, save it, and then open it in a browser. ChatGPT's new canvas feature is great for generating code, but it doesn't provide a way to preview HTML directly. To solve this, I made a small bookmarklet that allows you to instantly preview HTML from your clipboard in a new tab. Just copy your HTML, click the bookmarklet, and it will render immediately. It's a simple tool, but it’s saved me a lot of repetitive steps, and I figured it might help others too. The bookmarklet code and…

http://instantclick.io/ It seems the internet architecture won't bring us instant websites anytime soon. So here is a hack. I released this JS library last month (today is version 2.0 release, fixing v1.0's rough edges), it makes use of HTML5's pushState and preloading to make a website instant. It works like this: before clicking on a link, you'll hover over it. And there's a delay of 200-300 ms between these two events. InstantClick uses this delay to preload a page, when you click on a link it will display instantly in most case. (You can test on the website.) That's…

Here's the website: http://markup.io/ We created MarkUp at Medium to help make the QA process better for sites we're working on. Grab the MarkUp bookmarklet, go to some page in your browser, then click it to draw on the page. Publish to make a link you can share. We've tried similar tools like BounceApp, Notable, and Skitch. Everything else we found is screenshot-based or takes us out of the browser. We wanted something that felt quicker than screenshots and more integrated with the browsing experience. Instead of taking a screenshot, MarkUp snapshots the DOM in the current page, strips the…

Hey everyone, I built a simple React/Python app that takes screenshots of websites and converts them to clean HTML/Tailwind code. It uses GPT-4 Vision to generate the code, and DALL-E 3 to create placeholder images. To run it, all you need is an OpenAI key with GPT vision access. I’m quite pleased with how well it works most of the time. Sometimes, the image generations can be hilariously off. See here for a replica of Taylor Swift’s Instagram page: https://streamable.com/70gow1 I initially had a hard time getting it to work on full page screenshots. GPT4 would code…

Hi HN! For the last 8 months we've been working on leaflet.pub, a web app for making delightful documents. We're trying to strike a balance between Notion and Google Docs — very fast, ultralight and easy to share, but also supporting rich blocks and multiple pages. Weirdly, none of the many notetaking/document apps that we could find hit this combination, so we made Leaflet. With it you can: - Instantly create a doc, without an account - Share read and edit links - Sign-in with email to sync your docs to different devices - Add rich blocks, like canvases, subpages, rsvps, and polls It's…

I like playing around with bookmarklets (bookmarks that are executable JavaScript) And I wanted to make a Quine (code that prints a copy of its own source code ad infinitum) So I made a bookmark-only notepad that saves a copy of its own executable and current state to a JavaScript executable bookmarklet. As you type, a link on the page updates with the source code and the internal state. You can drag this link to the bookmarks bar to “save” your work. Works cross device if you have browser sync on. No server involved!

Here's a project I've been working on for a little while now. Ripl is a JS library that provides a unified API for rendering shapes on both canvas and SVG interchangeably. Over the years I've used D3 extensively to create data visualisations so I figured I'd have a go at making my own version with a slightly more modern API and stricter TypeScript support. I am aware there are already libraries that can draw to multiple contexts interchangeably, but I've added a few little niceties to Ripl that (as far as I know) some other libraries don't have such as CSS-like query selectors, DOM-like…
