Building in public doesn't come naturally to me. I overthink, stress about engagement, get lost in timelines. Tried schedulers, web blockers, willpower - nothing stuck.

So I built YapYap, a macOS menu bar app with global keyboard shortcuts: - Option+X → X compose window (no feed) - Option+L → LinkedIn compose window (no feed) - Cmd+Enter to post, and back to work

Technical approach: It uses a webview to load the native compose UI. No API calls (avoiding X's $200/month pricing), no data stored on my servers. Your credentials stay in the app's sandboxed session.

The webview detects when you navigate away from compose (after posting) and auto-closes. Next time you press the shortcut, it's already loaded and ready.

Stack: - Electron + Vite - Global shortcuts via Electron's globalShortcut API - Persistent sessions so you stay logged in - Code signed + notarized for macOS - Auto-updates via electron-updater

€5 one-time purchase, macOS only.

Fizzy is a free, self-hosted Kanban-style project management tool that offers a modern and fun approach to task organization and collaboration, developed by the creators of Hey.com.

Hey HN,

My brother(Arjun Dhiman) (17) and I(Akshat Dhiman) (15) were handed our Dad's Business Instagram and Facebook with a simple “just handle it“. Before this we were studying data science and working on a SMMA.

We thought we could apply our new skills. Instead, we spent months in the manual-work trenches:

Late nights in Canva for every single post.

Begging ChatGPT for captions that didn’t sound robotic.

Trying schedulers like Hootsuite/Buffer and realizing they don’t actually create anything—you still have to do all the hard work.

It felt like a huge gap. We had data science skills, so why couldn’t we create a tool to do the creative work intelligently?

That’s why we built Wyna.

It’s an AI social media manager that creates and posts for you. You drop in a website once, and after that, you spend about 10 seconds a month telling Wyna to "go." It plans and generates 30 days of custom posts, reels (copy, hashtags, visuals, timing), and auto-publishes everything.

A key thing for us was no templates. Wyna is built to create fully custom visuals for every brand, so a B2B SaaS and a local gym don't look the same. Our goal is for founders to basically forget about social media and still look consistently active.

We built this from our bedroom in Gurugram over the last 4 months, bootstrapped with about $1,100 from our dad, all while juggling school. Today we launched on Product Hunt, and we’re both excited and completely terrified.

If you’re a founder, indie hacker, or just curious, we’d love your feedback:

Is the product solving a real problem or are we just scratching our own itch?

What are we missing?

Any brutal feedback is welcome—we’re here to learn.

This has been our dream project—taking what we learned in data science and building a real tool to solve a real problem. Any support or feedback from the HN community would mean the world to us.

Hi all,

I’ve built a small Windows utility called *System Information Dashboard* and I’d love some feedback.

It’s a portable system info tool that shows at a glance: - CPU usage - RAM usage - Disk usage - OS version and build - System uptime - Basic device/system details

A few design choices: - *Portable*: just an EXE, no installer, no registry changes. - *No network calls / telemetry*: it doesn’t phone home, no tracking, no ads. - *Lightweight*: written in AutoIt, meant to be quick to open, check info, and close. - *Optional sensors*: for temperatures/sensors it can open LibreHardwareMonitor as an external app instead of reinventing that wheel.

Motivation: I work as an IT technician and I wanted a small dashboard I can quickly run on a client machine to see the basics without installing heavyweight suites like AIDA64/HWInfo or digging through multiple Windows panels.

Links: - Download / info page: https://www.gexos.org/system-information-dashboard-lightweig... - GitHub (code, README, changelog): https://github.com/Gexos/System-Info-Dashboard

I’m mainly looking for feedback on: - UI/UX (too simple? missing obvious info?) - Any red flags in how I’m gathering system info - Features you’d expect from a minimal sysinfo tool that I may be missing

Happy to answer questions and hear criticism. If you spot bugs or weird behaviour on your setup, please let me know your Windows version and hardware.

Hi guys,

Wanted to share a project I have been building for a while: Holesail, a lightweight peer-to-peer tunneling tool that makes sharing local self-hosted services extremely easy.

No port forwarding, no VPNs, no servers in the middle — just a direct, end-to-end encrypted connection between two peers using a simple connection key.

It supports both UDP and TCP and runs on Linux, Mac, Windows, Android and iOS.

The goal is to make Holesail the go-to solution for developers, hobbyists, and teams who need fast, reliable, private connectivity: hosting dev servers for teammates, sharing localhost, enabling LAN-style multiplayer, remote access, SSH, self-hosting or P2P features in applications without managing networking complexity.

It is the perfect alternative to Tailscale and Cloudflared.

Would love to hear feedback from anyone working with networking, P2P systems, or tunneling tools.

Happy to answer any questions!

Thanks

I like programmable LEDs. WS2812 strips, NeoPixels, addressable matrices—they’ve enabled ambient lighting, and interactive installations. But lately I’ve been wondering: what’s the hidden environmental cost?

Most consumer-grade RGB LED strips are not repairable: one dead pixel often ruins the whole strip.They’re typically built on flexible PCBs with mixed materials, making recycling nearly impossible.And while individual LEDs draw little power, large installations (e.g., 300+ LEDs at full white) can easily pull 30–60W continuously—comparable to an old incandescent bulb, but running all night as “mood lighting.”Yet in maker tutorials, hackathons, and even commercial smart lighting, sustainability rarely comes up. We optimize for brightness, color depth, and latency—but not for lifespan, repairability, or standby power.

So I’m genuinely curious:Are there modular, repairable LED systems being developed ? Could we design these systems to sleep deeply when idle, or use local sensors to avoid unnecessary illumination? Or is the energy impact so small that it’s not worth worrying about?
