Checked my Umami stats this morning - straight from Claude Code via my Umami MCP 📊 ~30% of visitors are on mobile… and every single one hit the "desktop only" gate. Shown 11 times, 0 continued past it. A third of traffic couldn't even try it.

I’m excited to officially launch ClickSploit. Check it out here: What started as a fun side project turned into a cybersecurity-themed idle clicker game. I built ClickSploit by using AI to help bridge some of my coding gaps, while leaning on my IT and tech experience to shape the game’s concepts, progression, and terminology. The game is meant to be fun first, but also gives players a small look into real cybersecurity ideas like alert triage, threat intelligence, vulnerability management, endpoint detection, identity security, automation, and building a stronger security program. It’s not a technical simulator, but it is a fun way to get a light introduction to tools and operations that people in cyber and IT work with every day. ClickSploit is accessible directly in your browser on both desktop and mobile phones, so there’s nothing to install. Mobile App development is in progress! This is still early, and I’ll continue improving the game with new conten

Practice intraday trading execution with hidden-date historical market sessions.

Trading Practice Platform I’ve always found it difficult to get meaningful practice outside of market hours, so I built a browser-based replay platform to solve that problem. You choose a stock or ETF, time of day, and up to three indicators, and it randomly loads a historical trading session from the past six months. The goal is to practice taking trades as if they were happening live. It includes: Basic and advanced TP/SL management AI trade reviews with a performance score after each

Marketplace where software builders pitch ideas and sponsors fund projects with milestone-based rewards.
@VibeStarter1 · X
is a crowdfunding and idea-bounty marketplace built for the vibe-coding generation — think Kickstarter+Upwork+Gumroad. Our simple thesis: Millions of people are now building real software with AI in days, not months. They have no structured way to validate demand before they build, no funding infrastructure built for how they work, and no marketplace for what they create when they’re done building it. Every existing platform — Kickstarter, Upwork, Gumroad, etc — was built for a different kind of creator. VibeStarter is the builder economy operating system — crowdfunding to get funded, a bounty board to get commissioned, and a marketplace to sell, license, or hand off what gets built. One platform, one reputation system, one trust layer across the entire lifecycle of a vibe-coded product. The two-word version: Builder Economy.

Play a text RPG where AI narrates the story while game code controls mechanics.
u/OldWiseSloth · Reddit
Heya! I'm building a text RPG where the AI is only allowed to narrate — actual game code controls every number, need Feedbacks/suggestions/tests! Cheers! "bow" Solo dev here, zero coding sense. Been building this for months and it's finally at a point where I want more people breaking it. It's called Realms: Shinsekai — a browser text RPG. The pitch is simple: most AI text games fall apart because the model controls everything, so your HP drifts, your gold appears out of nowhe
