Products that do what synchtube.com Synchronize YouTube videos does

As I write on the site: "synchtube allows you to instantly create public and private rooms where you can synchronize YouTube music and videos with up to 50 people" I've been working on this on and off with a friend, and we just recently made a big push to make it stable and scalable. I never thought I'd say this, but I think I'm finally happy with it now. The code feels clean internally (whew), and the site presentable. That being said I wanted to show it off! This app was inspired mostly by coincidence. At the time my friend was studying for med school and wanted to watch surgery vids with…

    Hey folks! My weekend project, Summify.io, has officially launched! It's an AI-driven tool that simplifies your life by summarizing YouTube videos in just a single click. Now, you can get the gist of those long vids without breaking a sweat! Built from the ground up as a solo developer, it's been an incredible journey full of late nights, countless coffees, and the spirit of indie hacking The amazing response from our private release has motivated me on to start building even more features. Can't wait for you to check it out and share your thoughts! Try Summify.io now and let's me know what…

    Hey HN, I'm a longtime reader and this is my first Show HN (exciting!) It's a collaboration between me and two friends, and we're building this upon another app we made called EmailYak, an API to receive email. We're trying something new and releasing the documentation to an app while we're still building it. We'd love feedback. Do you belong to any of these categories? 1) You've built an app with two distinct groups of users (say, people with cars and those looking for a ride) and they were able to communicate with each other. Did you expose personal email addresses? Did you send…

    Hey all, I created http://cueued.com that works as a remote for a collaborative spotify queue where the users can upvote and downvote music they want to hear next. Only the person who is playing the music needs to have spotify premium! And if you're far from your friends (and have premium) and want to listen together, you can go to the settings and click Connect to Room, and you all can listen to the same music remotely. Let me know what y'all think about it, and any improvements as well. And if anyone's interested in how I built it let me know as well.

    Do you want to monetize a private group/ channel/ community? Use Subjoin to create a personal membership page in minutes. It's easy to use and free to try out. No need to integrate Stripe if membership is free. - - - - I have never built something this fast, what a thrill! I saw there was no easy way to create a simple subscription page. Big platforms are confusing and expensive for simple needs. - - - - What are you building? Would love to connect with like-minded people on X: @tjmakingof

    Hey HN!! Many of us enjoyed the "If YouTube had actual channels" Show HN post last week. As developers of a similar project, we wanted to share our approach to building a simulated live experience. We’ve spent around 18 months working on this and have managed to add some advanced features, including content-based interactivity. We are super excited to be releasing both the live stream and the code behind it. Our idea was to combine the communal watching experience of television with the modern trappings of the interactive web. If you go to the stream, you will be watching along with everyone…

    One year ago, I downloaded the news.arc code and decided that I would teach myself programming by building a better aggregator. At that time, I had some rudimentary HTML knowledge, and little FORTRAN under my belt. I knew that I wanted an aggregator that could support a wide range of submissions, and one that could scale without losing quality for the user. Hubski is what I have to show for my time and effort. The easiest way to describe Hubski is to say that it uses a commenting system akin to HN or Reddit, but uses a sharing scheme like Twitter. You have a personal feed comprised of the…

    I know mentioning Michael Seibel is almost cheating, but this week he demonstrated the "leaky pipes" concept to me. Not that I know the guy, but in one of his videos he says something on the lines of "If you are unsure if you app is ready to be launched, just launch it. It's like a house with leaky pipes, just open the main, grab your tools, and start fixing wherever water is leaking". So we did it, we launched drummy earlier this week on /r/InternetIsBeautiful and we got very close to 10k users in just one day! Survived the hug of death, learned a ton, and made changes all around.…

    Hello, HN. I'm a long-time lurker here and this is my first Show HN (be gentle). I created Glue which is best described as "Twitter meets Tumblr meets Medium" which is longer than just saying another Twitter alternative but IMO not 100% accurate. I launched Glue in mid '21 and have been slowly iterating on it since. Glue lets you share text, photos, video, audio, code snippets, quotes or break out into a long-form blog post. Posts on Glue are called "Drops". Glue in action: - My profile: https://glue.im/noah - Audio:…

    Building integrations for TikTok, X, Facebook, Instagram, YouTube, and LinkedIn got frustrating with how different every platform is with auth setup, rate limits, and media requirements. So we built Post for Me: one REST API that handles scheduling and publishing posts for TikTok, Facebook, Instagram, X, YouTube, LinkedIn, Pinterest, Bluesky, and Threads. It's built for developers. You bring your own app credentials from the social platform, so you're in control of your data. There's no limitations on account connections, and pricing is based on usage (not some arbitrary limitations). We…

    Hey HN, My co-founders and I have been working on a project for the last month or so, and we'd like to get your input on it. We wanted to hear your thoughts on what we're doing - so check out our landing page, and let us know what you think/understand. Does it sounds like something you guys would want to use? http://www.thesharedweb.com/alpha/intro We'll tell you guys more about exactly what we're doing as the conversation evolves, but we just wanted to see what the initial reaction is, and what you understand (i.e. are we describing it in a way that makes sense). Really excited to hear your…

    A buddy and I decided to hack on this little project this weekend, putting in about 12 hours. It's running Ruby on Rails, deployed to Heroku. We tried to keep things super lean with different gems handling user accounts, mailchimp for an email list and super lean styling/layout. Everything should work well enough on mobile devices, too, so give it a look! Right now the magic all happens via the Soundcloud API (of course), but we're exploring different ways to make this appeal to a broader audience of music listeners. We'd love your feedback! Here's the site:…

    Hello HN, I had some christmas free time over the last two weeks (Merry Christmas btw ;-)) and used that time to completely recreate the website of my app[1]. I used all the fancy new tools. I didn't know some of them when I started. What was my goal? * Pretty website * Blazing fast * Mobile first * SSR * Webp support * Generally all the best website practices (high lighthouse score) What did I use? * Tailwindcss (https://tailwindcss.com/) * Tailwind Components (https://tailwindui.com/) * React (https://reactjs.org/) * ViteJs…

    Initially, I was interested in using YouTube videos to learn languages using the simple shadowing technique. It sounds fancy, but it's simply listening and repeating. However, I found it pretty inconvenient to use the vanilla YouTube player to replay video parts. Especially when I needed to do it several times. Later I figured out that it's pretty handy to also practice instruments, given how much material is in there. Not just for mimicking songs but also for better following tutorials. So the idea is simple, you can save clips you want to practice to loop as many times as you want and come…

    >>>>> TimeForZen.com <<<<< This took months to put together. Learning javascript, using the sound manager 2 api. Finding the perfect creative commons photos on flickr. It's such a ridiculously simple site (just a curated list of music) but I went through hell debugging and getting it to work. I learned an extreme amount. My advice to designers who can't code, keep it simple, just get it done don't worry about optimization, don't worry about a backend. Code everything manually if you have to. I've kept it simple out of necessity. I'm a designer, not a…

    Hey HN! Last week I was working on a website and needed a way to synchronise visuals with live music. I've used MIDI controllers for this before, but I am travelling right now and don't have mine with me. So I had the crazy idea to build a browser extension that uses the keyboard as input and includes a sequencer. I gave myself 24 to work on it. It ended up taking longer (of course), specially since I ended up creating a demo, a small landing, docs, and an intro video. Took me one week from idea to launch (pushed quite a bit tbh). Features: - Works as a browser extension. Atm distributed…

    http://dripi.com I thought I'd share my winning entry to the Google I/O last call competition with ya'll. Took me about 9 hours, which seems like a lot looking at it now (my only excuse is that it took place after 12am). I truly did not expect to be one of the winners. My guess is that the YouTube API category had fewer entries than others. Feel free to let me know what you think! This was the challenge: Wouldn’t it be nice if you could create a video mash-up by chaining player invocations that work for both Flash and HTML5 videos ? Well, with the JavaScript API to the <iframe> embed…

    Just wanted to share with you something I built. If you’re a creator or someone who financially supports creators, this will be of interest to you. Qufro.com is a site where creators can monetise their fan interactions. It works this way: A creator sets an amount for answering fan questions. A fan posts a question or a comment and is only charged if the creator responds. From the fan’s perspective, we’re solving the following problem: Not all fans want to commit to a monthly subscription (e.g., on Patreon) to support their favourite creators. With Patreon, ko-fi, etc., there is also no…

    Hi, I spent the last couple of months developing OurClubFundraiser(http://www.ourclubfundraiser.com) and launched it about two weeks ago.I would love to get some feedback from the HN community on how I could improve the site and tweak the concept. Since launching I have found that: 1) I am not getting enough visits(Average around 5 a day) 2) Any of the visits I do get are not converting. I am working on 1) and will hopefully be able to dramatically increase the number of visits over the next few weeks. I could really do with some third party perspectives on point 2. 1)Is the concept not…

    Live demo here: http://fonctionlabs.com:8000 Similarly to aka_sh (guess we were working parallelly on similar topics), I created with my brother a chainlit-based webapp, which summarizes Youtube videos in order to gain time. It works as an RAG-based LLM, and is very light in the sense that it does not use RAG libraries like langchain or llamaindex. You can use it with your own OpenAI API key. It also supports local models like Mistral, or Llamma. It is ofc open-source, and you can deploy with Docker if you choose. Some of the next steps are: - using whisper to be able to compute a…
