Hey everyone,I'm a solo dev and I built CareCoin as a side project to make crypto donations as simple as possible. I built this small web app that lets you send ETH directly to verified charitywallets ( right now I have UNICEF, UNITED24, IRC, GiveDirectly, etc.). No sign-ups, no fees, no middlemen just for now accepting connection with MetaMask and donate. It also supports Superfluid streaming if you want to set up recurring donations.
So I made a landing page to hold all privacy and support pages, and also a clean landing page for the apps I'm making. Check it out and give some feedback! Currently have a freezer organizer FRZR, and a daily mood tracker, DailyFeels
I m building an email sending platform and considering a pay as you go model instead of subscriptions. My reasoning is that many people don t send emails every month, so charging only for usage feels more fair.
However, several founders have warned me that this model may be a mistake from a business perspective.
If you ve built or used similar tools, I d appreciate your thoughts on:
At the end of last year, I completely fell in love with using Claude Code. After I found out how accurate it was in translating my context into functional products. I was hooked and immediately launched two products Vibe & Snapp However, I quickly realized that there was an opportunity to improve the building experience that IDEs didn't quite address? I wanted a very simplified IDE with the quality of life improvements that a lot of no-code tools gave you but without the lock-in they seem to have and agnostic to my stack.
I ve seen a lot of VR and AI projects in healthcare get rejected or ignored on Product Hunt because they lead with technology instead of learning outcomes. So I want to approach this differently.
This Idea Usher review looks at VRion Lab, a virtual reality based learning platform designed to simulate science and healthcare labs when physical infrastructure is limited. I m not posting this as a launch or a showcase. I m posting it as a discussion about where VR genuinely works in healthcare education and where it doesn t.
The real problem VRion Lab is trying to solve
In healthcare and science education, the biggest bottleneck is not content. It s access.
I built this for myself. Technical founders tend to either over-engineer their planning or ignore it entirely. FounderScope is the middle ground: opinionated enough to give structure (Osterwalder's BMC/VPC framework, experiment lifecycle, Stage-Gate roadmap), flexible enough to not feel like corporate consultancy theater.
Key differentiator: every hypothesis is a first-class object. You don't just write it on a sticky note you link it to experiments, track validation status, and connect it to your financial assumptions. When something gets invalidated, the whole model knows.
Early stage, but functional. Would love feedback from founders who've been through lean startup cycles.
