Products that do what Rejourney – Open-source revenue leak prediction for web and mobile apps does
Hello there (General Kenobi's favorite way to start the conversation), I’m Rashid, a sophomore at UT Austin. I built Rejourney.co (https://rejourney.co/) to predict issues with your apps and websites before they happen, based on real user session recordings. Here is a silly video (with cats) on how it works: https://www.youtube.com/watch?v=Z95MDxBXMjk It’s open source, and the post link is the github repo, but here it is again: https://github.com/rejourneyco/rejourney I originally built this because I had a campus freebie finder app that grew…

Hi HN, I built SubTrack to help teams find unused SaaS tools and cloud resources before they silently eat into budgets. The motivation came from seeing how hard it is to answer simple questions: – Which SaaS tools are actually used? – Which cloud resources are idle? – What will our end-of-month spend look like? SubTrack connects to tools like AWS, GitHub, Vercel, and others to surface unused resources and cost signals from one place. Recently I added multi-account support, currency localization, and optional AI-based insights to help interpret usage patterns. This is an early-stage project…

Hi all, I like RethinkDB a lot. One year ago, I started to document it because I want to learn more about it. At first, I blog, at one point I started to writing it in markdown, using pandoc to convert it into PDF then I switched to Leanpub. At some point, I almost abandon it. But finally I make effort to go back and almost finish it. Here is the result of one year: http://leanpub.com/simplyrethinkdb I also open source it on here(But it helps if you make an purchase on leanpub anyway :D): http://github.com/kureikain/simplyrethink The book is still WIP…

I wanted to share something I've been working on recently: Statum, a handy web analytics tool. https://github.com/extractumio/statum The journey began when I found myself frequently needing simple web analytics for my projects. I tried Google Analytics, especially GA4, and realized it was quite complex and, at times, not very accurate, especially when I wanted to view stats for the current day or recent hours. Then I tested a few fancy startup solution but ended up with way too expensive plans the expect me to subscribe (I'm not that rich to pay $99/month for every…

Hi HN, I'm the CEO at https://replay.io. We've been working on time travel debugging for web development for a while (https://news.ycombinator.com/item?id=28539247) and more recently an AI app builder that uses that debugger to get past problems instead of spinning in circles (https://news.ycombinator.com/item?id=43258585). We've gotten to where we can pretty easily build apps to replace business-critical SaaS tools, some of which we're now using internally: * We built our own issue tracker to keep track of all our development projects, tickets, bug…

I've built a little prototype a long while back, to help me keep track of visitors on my website. I didn't like google analytics for obvious privacy reasons, and I didn't like the existing self-hosted options because of how complicated they are. I always wanted a simple, basic tool, similar to plausible, but even simpler. So a few weeks ago I rebuilt my prototype into a reusable tool. And I made it open source. I built a website, a documentation, and I'd be excited for someone else to try it too. Who knows, maybe if enough people like the idea, I might even make it into a SaaS to save…

I built this after one too many 3 AM wake-ups due to API outages. Existing solutions felt overpriced and overcomplicated for my small-scale needs. Key features: Simple, GitHub-inspired dashboard Free tier: 5-minute checks, email alerts, 30-day retention Premium tier: 1-minute checks, SMS alerts, unlimited retention Significantly more affordable than enterprise solutions Tech stack: Next.js frontend, Node.js backend, MongoDB, Stripe for payments. This is my attempt to solve the "sleep vs. downtime" dilemma for fellow indie hackers. I'd appreciate any feedback or feature suggestions. What's…

I spent last 6 months trying to build Simple Ops [1] to democratize website performance monitoring so anyone can use it. A year back, while I was trying to measure performance for Visa List as it became a huge content website with more than 100K pages. Also as data is changing very frequently, it's very hard to keep doing this manually. I searched on google and found that all the solutions are just uptime monitoring and nothing and none of them truly measure performance. So I decided to build one for myself. But it turns out website performance monitoring is not so simple after all and with…

Hey HN! I’m excited to introduce Companero, my open-source ridesharing solution! As a traveler, I often struggled to find rides in smaller cities. So I built Companero on Telegram using pure Java 21 and MongoDB. I recently added a rating system to this app to make rides safer, but all in all, you can request a ride using your location, can see recommended trip price based on your country (it has an index for each country and a currency converter) and much more features. I’d love your feedback and any questions are welcome! Thanks!

I use multiple AI tools for work and also my side projects, and the annoying part was to track my costs and token usage across tools. Everytime I had to visit each tool and its respective usage setting to check it and I was losing patience and also was getting hit by surprise limits Now I know that there are already free/open-source trackers for Cursor or Claude usage, and they are useful if that is all you need. My problem is broader as I wanted one small place to see tokens, spend, subscriptions and limits across the AI tools I actually use. I was really tired of switching tabs and…

Hey HN, I started my career as a finance manager, transitioned into product management, and now I’m building my own products. Back in my finance days, while managing a £6M budget, I uncovered a £15k leak hiding in plain sight: FX fees. Today, I see solo founders making the exact same mistake. I realised most founders are quietly losing 2-5% of their revenue to what I call the Lazy Tax: - Stripe's ~2% auto-conversion fee on inbound revenue, - plus their local bank's ~3% spread when paying for global SaaS tools (AWS, Claude, Ads). So I built FixMyFX to show founders their exact leak and how to…

Hi all! We are a tiny team of two that enjoyed using del.icio.us back in the day. It was a simple and efficient tool for two things: saving urls for later, and browsing the web thanks to the tags and some other basic features. So we wondered about rebuilding it. Its been quite a ride, but we finally have a streamlined version of what we are looking for. This is www.urligram.com: a prototype for a new social bookmarking platform. We have been using it for some time, and while there is a lot of work to be done yet, we think it is stable enough to be useful. Currently you will be able to save…

Introducing my latest project, We Build Landing Pages. https://theredbit.github.io/webuildlandingpages/ Excuse the blatant infancy of the project but I take 'releasing early and often' pretty seriously. The goals of this project are to... 1. Build a solid network of clients who need landing pages while learning how to run a business and to help earn funds to survive while I search for a job. Long story, I'm in a rough spot and I'm trying to get on my feet. 2. Build and release open-source tools and foster the growth of a community based on this work to help developers…
