Hey HN,we built playplanet.dev, a Lovable alternative that lets you build and run full stack apps entirely in the browser, no server needed. We run it on a Linux like system compiled to WebAssembly and then use a runtime on top of it. Currently we support frameworks like Astro, React, Angular, Vue and Svelte.You connect your own OpenRouter account and use it to build out the code with an LLM,...

Hi HN, creator of EmbedPDF here.I recently posted my open-source PDF viewer here, and one thing I really value is that it runs completely offline. I started wondering if we could push that further: could we do full ML layout analysis (detecting tables, headers, columns) directly in the browser?To my surprise, it actually works.The catch: It is far from production-ready. It crashes on most...
That’s great to hear, contributions are very welcome! If you’re interested in working on outline editing, feel free to open a discussion or draft PR and we can figure out the best way to integrate it.
Thanks for sharing! It looks like the pdfreaders campaign has actually ended and the site is no longer updated, so I’m not sure it’s still being maintained as a resource.
It doesn’t support editing outlines yet, but it’s definitely possible and something I plan to look into. I don’t think it should be too hard to add.
Thanks! The redaction issue in Firefox should now be fixed.
Thanks! Glad to hear it’s working well on Firefox for Android.
Thanks for letting me know, that was related to a Firefox-specific issue I’ve just fixed. Annotations and redaction should now work in Linux + Firefox as well as Chromium.
Yep, that’s exactly the issue! I’ve fixed it so it no longer throws the TouchEvent error in Firefox. Thanks for flagging it.
Thanks for pointing that out! I’ve fixed the Firefox issue. And we actually already have Undo/Redo on the annotation toolbar.
Very easy, this already works! In the AnnotationLayer you can add your own `selectionMenu` and render any custom component there. If you want to dive deeper, join our Discord and shoot me a message.

Yes, those commercial PDF SDKs charge crazy prices! Time to change that.
Haha fair, but PDFium's under Apache 2.0, so at least the “cartel” in this case is about as open-license as it gets.
Yes, all of the above. The client-side PDF viewer will remain free and MIT-licensed, but I’ll be focusing on offering PDF hosting with enterprise features like analytics, access controls etc, those will be part of the paid offering.
This is really valuable feedback, thank you! I agree, having a simple, ready-to-use `<EmbedPDF>` component that includes all the plugins by default would make it much easier to get started. I’ll definitely add that alongside the more advanced example.
Thanks! Glad to hear it’s running smoothly on mobile, the rendering on iOS in particular feels really fast.
That means a lot to me, thank you!
Thanks! For now we’re only building a web app, but depending on demand we’d love to build native apps for Android, iOS, and desktop OSs as well.
Thanks! Signing is a high priority for us, and PKCS#11 and PKCS#12 support are definitely on our radar.
The main goal was to make a PDF viewer that is easy for developers to integrate into their websites with minimal setup, while PDF.js can be harder to customize and extend for certain use cases
Not on the roadmap yet, but I’d definitely be open to adding it if more people are interested.
Thanks! I’ve been working on it for about 7 months now.
Thanks! I wanted to make it as easy as possible for people to use, tweak, and build on top of it, so MIT felt like the right choice.
I haven’t had the chance to test annotations in Firefox yet, so thanks for pointing that out. I’ll check what’s going on there, good to know they’re working fine in Chrome.
Good catch, I’ll fix that. On mobile, it’s intentional that scrolling is disabled while in redaction mode so you can make precise selections, but if you switch back to the view tab it should definitely exit redaction mode. Thanks for spotting it!
We already support quite a few real PDF annotations: circle, square, polygon, polyline, highlight, underline, squiggly, strikeout,free text, stamps, and ink. Some types are still on our list, like links, form fields, sound annotations, file attachments, and 3D models. Do you happen to know what annotation type it is in your PDF? I’m curious.
Honestly, yours looks even snappier than what I had, the way it’s handling zoom feels super fluid. Really impressive work! Makes me want to dig back in and see if I can match that speed.

I built EmbedPDF: an MIT-licensed, open-source PDF viewer that aims to match all of Adobe Acrobat’s paid features… for free.Already working:- Annotations (highlight, sticky notes, free text, ink)
- True redaction (content actually removed)
- Search, text selection, zoom, rotation
- Runs fully in the browser, no server needed
- Drop-in SDK for React, Vue, Preact, vanilla JSWhy? Acrobat is heavy,...
