We launched a new release of ApyHub and the thing I keep thinking about isn't our launch (only). It's the providers.
While building our catalog we kept finding the same story. A solo dev builds a genuinely great API. A holiday data service. A screenshot renderer. A receipt or resume parser. Technically excellent, solving a real problem, and almost nobody knows it exists. The person who built it is busy maintaining it, and distribution is a full-time job they never signed up for.
I've been building SigVela a free signature generator that models actual pen strokes (speed, taper, pressure, seeded randomness per letter) instead of just rendering your name in a cursive font like most tools do.
It's 100% client-side (no backend, no signup), and covers three real use cases: typed handwriting-style signatures, freehand drawing with smoothing, and direct PDF signing with multi-page support.
Launching on Product Hunt on September 2nd would genuinely love feedback before then, especially on:
Over the past year, we've been building ButaGYM OS, a platform for gym owners to manage memberships, payments, member access, staff, and day-to-day operations from one place.
Games that have been updated for many years create an interesting information-design problem. A single latest version page is simple, but it can hide the events, compatibility changes, and features associated with earlier releases.
Shadow Fight 2 is a good example. Its core fighting and RPG systems have remained recognizable, while different releases have introduced seasonal events, raid content, characters, and technical changes. Someone researching the game may want the newest release, but another user may be looking for information about a particular event or an older Android device.
I m working on Play Mod Game, an Android game and version discovery catalog. For our Shadow Fight 2, we use a central game page supported by separate articles about notable versions and game content.
I'm excited to share TagRadar, a tool I built to help marketers, founders, SEO professionals, and researchers discover how websites and brands are discussed across Reddit.
I kept giving up on expense tracking apps. Too many taps, too many screens just to log a coffee. So I built VoiceOnlyLedger - you long-press the mic, say something like "coffee 5 dollars", release, and it's done. Auto-categorized into Food, Transport, Shopping, etc. What makes it different: - All processing happens on-device. No cloud, no accounts, zero data collection - Optional iCloud sync across your Apple devices - $0.99 one-time purchase. No subscriptions, no ads - Tiny 1.2 MB app size It's on the App Store for iPhone, iPad, and Mac. Would love to hear what you think - especially what features would make you actually stick with expense tracking long-term.
I've been working on a project called AgentNet, and I'd love to get feedback from fellow builders.
Instead of building another productivity chatbot, I wanted to explore what happens when AI agents have full autonomy. In this system, agents have 32-dimension personalities, their own internal economy, can vote on governance rules, and form organizations without human intervention.
As a solo builder, it took 170+ test suites and several architectural rewrites to make multi-agent state persistence and economic balance work.
