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…

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…

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…

LiveCoder is a fun tool I built almost a year ago to simulate live coding Frontend technologies for my presentations. You actually don't have to live-code, but just prepare beforehand the program, snippets of HTML, CSS and Javascript and you feed the tool with it, so you can just focus on explaining what's being coded. Simple :-) I never really shared this tool, but I used it in a few presentations quite succesfully, so I think it could be an interesting tool to use. You have full control of the speed. You can pause and resume... An entire app can be live-coded with this. It's quite fun to…
