ActividadX

Hi everyone!

I wanted to share a project I've been working on called ActividadX.

I built this app because I noticed how hard it has become to actually meet new people and make real-life friends, despite being more connected online than ever. The main goal of ActividadX is simple: to help you find people nearby who want to share real activities, hang out, or grab a coffee.

Key features:

Sick of my own Downloads folder. Built a self-destructing file manager.

RottenFiles for Free!
You know that feeling when you download something, tell yourself you'll sort it later, and then it just lives there forever? WhatsApp PDFs, random installers, screenshots you took for one Slack message. None of it worth keeping but somehow never worth deleting either. My Downloads folder had 500 files and I genuinely didn't know what half of them were anymore.

Couldn't find a tool that did what I wanted so I built RottenFiles (GitHub). You save throwaway files to a specific folder, and they automatically delete themselves after 7 days. If you actually need something before it's gone, you click Keep and it moves wherever you want. Do nothing and it disappears.

QueueThis! - NOW LIVE

QueueThis! : queuethis.io This is a project I have been working on for a while. The name of this project is called QueueThis! In this web app, people can listen to music together, using the shared queue system. In order to queue songs into the shared queue system, users must upload the song via any supported music file format that is listed. Once the queued song plays, everyone in the app will be able to hear it play live via synchronized playback. There is also a global chat feature where users can chat with each other while the music plays. People can also send direct messages to each other. This new web app is intended to be for users of ages 13 (with parents permission, that is) and up. Anyways, I would greatly appreciate feedback for this new project that I have worked on. I would like to know what everyone thinks about it. Suggestions are welcome too. Thanks.

Drop your idea. I'll map it validation score, PRD, and IA structure. Live in this thread.

A bit of context: I'm a UX/UI designer who got tired of wireframing ideas that hadn't been validated yet. So our team built Bunzee a workflow that goes from raw idea all the way to a handoff-ready structure in one session.

The flow: market validation competitor analysis PRD IA structure + design direction + MVP scope extraction.

That last part is new. We added it because the most common question we kept getting after people finished the PRD was: "Okay, so now I still have to figure out the actual screens myself?"

I built an app that teaches you the math behind poker.

Rake & Reason is an interactive, Duolingo-style trainer that teaches poker through the statistics behind it, not the other way around. Instead of memorizing charts, you calculate real odds, count real hand combinations, and make pot-odds calls on actual poker scenarios, with instant feedback on the math every step of the way. A built-in Monte Carlo simulator lets you pit any two hands against each other and watch thousands of outcomes play out in seconds, turning percentages into real understanding. It's built for anyone who wants to actually understand why a play is correct, not just be told that it is.

Just shipped 2FA to Uppale.com! 🔒

Hey Hunters! I wanted to share a quick milestone we just pushed live on Uppale.com, our community-driven visibility platform for local businesses. We just shipped a full vertical slice implementation of Two-Factor Authentication (TOTP) to protect our users' slots and account security. The most interesting part of this update is the architectural approach we chose, which was guided by two core principles: 100% privacy and zero infrastructure costs. Here is how it works under the hood: Adaptive / Risk-Based Auth: We hate tedious logins. Users are only challenged for a 6-digit security code if they log in from an unfamiliar device or location. Known devices rely on a secure httpOnly trust cookie to skip the prompt. Purely Cryptographic ($0 API Costs): Instead of using expensive SMS gateways that drain resources, we implemented a custom TOTP engine (otplib + Prisma). Secrets are stored AES-256-GCM encrypted in our Postgres DB, alongside HMAC-hashed, single-use recovery codes. Next.js 16 Stack: The feature is fully built on Next.js 16 (App Router) and React 18. It utilizes temporary session IDs stashed in Redis during the 2FA challenge window to completely withhold Supabase auth tokens until the user is verified. We wanted a production-ready system that is robust, accessible, and lightweight without paying a single cent for third-party API networks on every login, and 10/10 end-to-end tests are officially passing live on production. If you want to support the project, see how it's evolving, or drop some feedback on our backend approach, check out our launch page: Check out our official Product Launch on Product Hunt: https://producthunt.com/products...

I built an open-source visual studio for designing AI agent workflows:

I ve been working on AI Graph Studio, a free and open-source visual environment for designing, documenting, analyzing and optimizing agentic AI workflows and graphs. It lets you visually build workflows using LLMs, agents, tools, RAG, memory, routers, guardrails, human approvals, loops and other components, while also providing analysis, token budgeting, cost estimation and simulation capabilities. The project runs entirely in the browser, requires no API keys, and is free to use without limits. I ve also just made it available as a Hugging Face Space. I d really appreciate feedback from people working with AI agents and agentic architectures: what would you add or improve? AI Graph Studio: https://aigraphstudio.jordigarci...

I'm testing whether this behavior actually exists.

I'm testing whether this behavior actually exists.

I built Fleuves because social platforms are great at showing what people achieved, but terrible at preserving everything that happened before it.

Instead of posts being the center, you create a Dream and gradually build the history of that journey progress, failures, thoughts, photos and milestones. You decide what stays private and what gets shared.

But here's what I don't know:

Launching after $100K of creator payout

We put artha.link on Product Hunt this morning. Not featured in the top 10, but learning why we didn't.

But the good news is that we've already paid out $100K to creators for sharing jobs.

What's new in Publora since launch — now an API + MCP-native publishing tool

Hey everyone! Quick update on how Publora has evolved since we first launched here.

At launch, Publora was a Google Docs-styled social media scheduler with API access. Since then it's grown into something more focused: a tool built to schedule and publish across every platform from your own code or straight from your AI assistant.
