Products that do what Open-source RSVP app using Supabase and Flutter does
I'm doing a new Show HN[1] as we have now made this open source, and got some interest in comments in the past few days. We initially built this app for some friends in a co-living community - they were using pen and paper to track who's attending lunch - but it was error-prone. First I suggested a shared Google Sheets or Calendar, but that was also messy to maintain. Eventually, I developed something just for them. They used it for a couple of years, they loved it and wanted to use it for more things, too. So I took all the learnings from what was now the MVP, and with some friends we now…

Partially inspired by recent discussions on HN and other places. I've made a single-focus site to introduce your friends/colleagues/neighbours/family to RSS and web feeds. https://www.youneedfeeds.com/ The site is meant to give the elevator pitch for feeds, show a newbie what feeds are and how to use them, set them up with a reader, and give them some nice starter content if they want it. So much tastemaking and newsmaking power is concentrated in the hands of Facebook/Reddit/Twitter, but I'm convinced it's because much of the general populace doesn't…

This was my first attempt of making something truly appealing and useful. I've learned a lot and I'm pretty happy with the result. What do you think?

HN, I've been mostly lurking, semi-active on HN for over 4 years. For most of that time, I've been working on my startup, Learndot. I have always wanted to do a "Show HN" post, but I never thought it was ready. We've now finally launched web signup and using a freemium business model. I feel I can now post and offer something to the community (a new app to try out) and hopefully get good quality feedback. Here's the site: http://www.learndot.com Would appreciate any or all thoughts: From pricing/positioning, to design/performance. The app is written in Sproutcore and backed by an API written…

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…

Hello hackers, I just launched a new MVP It's a todo app using mapped todo lists instead of regular lists ! https://ymappr.com It's bugged and very beta, but I released this complex MVP in only two weeks ! (+ made while relocating from Thaïland to Vietnam, and even while being sick). Needless to say, despite the raw interface, a lot of efforts was put into this. Hope I can give you a feel of what the final product will look like, and I would appreciate some feedback In the meantime, take care! baz

Hi everyone, I've been building a less bad way to share photos and videos out to friends and family: https://vzg.me The motivation is personal for me since... 1. I'm not comfortable using Facebook properties 2. Group SMS/email gets out of control with more than a few recipients 3. I don't want to convince my friends and family to download a new app or figure out shared albums So I created a system that lets my network subscribe to individual people in my family and get updates via email, SMS, or RSS at the frequency of their choosing (immediate, daily, or weekly). Subscribers…

Hi, i was wondering what the HN community thinks of this email tone check application? Do you think this can be done better with open-source? Disclaimer: I am neither a founder or an employee at the company. Just someone who had a similar idea.

This is my first web app, so there are bound be to be a few kinks that need to be worked out. That's why it's here, in hopes that some of the awesome people I read about on HN can take a minute to offer some criticism. http://dailydo.it/ DailyDo.it is meant to replace the canonical to-do list with a do-it list – a list of things that you will actually do. My monetization plan is based on team do-it lists, where you can see your teammates' do-it lists and assign them tasks, while keeping the individual do-it lists totally free. Please let me know if you find any bugs, what the pain points…

Hey Mac, Jacob, Dominic and John here from the Commsor team. We originally built this for internal use to solve a frustration we had around manually sending calendar invites for virtual Zoom events we were hosting. We decided to polish it up a bit and release it for anyone to use, completely free. It enables you to quickly spin up an event page, collect RSVPs, send calendar invites, and export RSVPs. We've also built a host page for those hosting multiple events, making it easy to share one link with all of your upcoming events! You can see it in action here -…

I've been playing around with Android development recently, and made this Hacker News app this weekend: Market link: https://market.android.com/details?id=com.mellort.hackernews ($1) Dropbox link: http://db.tt/jlqIcBg1 (free: if you like it, DL from the market, too!) I used api.ihackernews.com for the data. Unfortunately, some of the pagination from that source is broken, so I can only return one page of results. In the future, I might play around with creating my own API server on App Engine. I'm not sure what my plans are for the source yet, but I'd like to make it open source. If you're…

Hi! Recently I've launched - mybfio.io - platform for software reviews with social network aspect. Prehistory Many great system are already in place that allow people to search and rate software products, including the site I am publishing this post on. However I have always felt that those systems are not specifically centered around product/software development lifecycle (releases, real users feedback over a product entire lifetime, so on) and often too broad or not designed specifically for that type of work, which is ok. Why? As an opensource author I would like to have constant…

I recently launched my first web app, polls.io. It's a super simple polling app that doesn't require sign-up. In my opinion, this is the most simple/social polling app out there. There are certainly many similar apps out there, but I think this one stands out as it straight-forward and doesn't have any unnecessary "mess" getting in the way of the actual poll. From idea to inception this took about a week. I'm pretty happy with how it turned out. We'll be listening to feedback in the coming days/weeks in order to make the proper changes. I'd love to hear your guys' thoughts and feedback!…

Hi HN, After I finished my thesis on feedback management for SaaS at the end of last year, I thought it was time to do something hands-on that topic. Since I like the idea of such feedback tools, that lets you collaborate with users to find solutions together - instead of having a separated feedback from each user - this became my starting point. I also like the approach of the chat widgets as they make it easy for users to get in touch with the people behind the app. So I tried to combine these two approaches with sleekplan.com. Here are some of the main features: * Collect & discuss…

I've always wanted to follow podcast guests across shows, not subscribe to entire podcasts. Most of the time the podcasts host guests which I don't really care about. When a guest you follow appears on a random podcast, they will appear as a new entry in the rss-feed for that particular guest. Hopefully some here will find that useful :D

Hello! I built a web-app called JungleReader that lets you follow RSS, Mastodon, YouTube, Reddit, and random blogs, all in one place. I made JungleReader as a central place to follow the blogs and sites I like, which I otherwise often lose track of. My next project (which is WIP) is a web-app called JungleWriter where you can build a simple blog and export it for hosting. I love finding a good, free-standing blog, and hope to make it easier for people to read and write them. Feedback is appreciated, thanks :)

Hi guys! Our team of HN lurkers been hard at work for what feels like an eternity now and today we're proud to present our first public product: The Walkbase library for Android. You can get it at www.walkbase.com With Walkbase, app developers can push location-specific room-level context (e.g. in-game content, coupons, mobile ads) to various smartphone apps. The idea is to give you a logical context (e.g Starbucks, SOMA) rather than an approximate GPS position for your users and we hope devs will be able to build a bunch of cool stuff on top of this. We hope you like it and find it useful.…

Hi HN! Flocklist.app is a minimalist, private dependency tracker. I mostly just built this for myself, since I would sit down to work, look at my to-do list, and I couldn't do 2/3 of the tasks. None of the solutions to this really cut it, either because they are a little clunky or are enterprise scale (like Jira, Linear, you know the rest). I figure I can't be the only one with this problem, so I built this free app to fix it. (It also doesn’t store tasks in the cloud.) I would love to hear any feedback you have!

I am announcing the private beta of my first web app (http://getfounder.com). The beta will launch in just one city, which will be determined by the number of entries on the location-aware sign up page. As this is my first public release, I'm looking to the HN community to offer me feedback on what I should/shouldn't be displaying on the homepage. I'd be grateful for any advice you had to offer. Thanks, and I hope to see some of you in the private beta! Colin

Hello HN! Here's my November Startup Sprint project (coded in two days). http://hackerlunch.com It allows you to post your lunch plans and lets other hackers join you. I built this because I often see HN users are interested in meeting each other if they are in the same area. I am not a coder, so this version is very rough. If people use it, I will work with others to build a more polished version. I would love some feedback. What do you think? Is this something you will be using?

Hi HN, Two things inspired me to build this: Andrej Karpathy recently talked about going back to RSS feeds — "higher quality longform and a lot less slop intended to provoke" (https://x.com/karpathy/status/2018043254986703167). Around the same time, Marc Andreessen shared his information source: 25% X, 25% podcasts with practitioners, 25% conversations with AI, 25% old books (https://x.com/pmarca/status/2030949039345467570). This made me realize how much it matters to control what you let in. But I've used to the feed-style reading habit…

Hi All, I’ve been working on an open-source SDK to make collecting user feedback on your website less painful. Instead of wasting time on building your own feedback system and boring forms, my SDK lets users leave feedback directly on your website—with all the context devs actually need. Here’s what it currently does: Users can select any element on the page Auto-captures logs, metadata & screenshots Sends instant notifications (Slack, Discord, etc.) Lets you reward users → boosts engagement & conversions Gives users a tracking link → builds accountability & trust Self-host + customize the…

After I posted about https://cosme.dev/ask-docs on Reddit I received some messages asking me how If I was going to make the code open source or if I could show them how I did it. So I decided to create this repo so you can take a look at the code and maybe apply the same techniques on your own apps. It's made using only PHP as language so I think is pretty different since most stuff out there is made using python or javascript. It uses the OpenAI API and Redis as a vector database.
