  • Shareable invite link with WhatsApp, email, and copy-to-clipboard support
  • RSVP dashboard with attendance totals, guest messages, and data export
  • One-time pricing per event, no subscription

BananaSketch

Turn your kid's drawing into a photorealistic AI image in seconds.

BananaSketch is a mobile-first web app that takes a child's scribble and transforms it into a detailed, photorealistic image using AI. There is no app to download and no creative skill required. Draw something, hit generate, and watch it come to life. Install it as a PWA on any phone and hand it to your kid.

  • Sketch-to-photo AI generation delivered in seconds
  • PWA installable on Android and iOS without an app store
  • Free tier with watermarked output; premium removes the watermark and bumps resolution
  • Sketch history so every creation is saved to browse later

BugBarn

Self-hosted error tracking that runs on a €5 VPS.

BugBarn is a single Go binary that receives errors from your applications, groups them into issues by fingerprint, and shows them in a web UI. It writes to SQLite and spools events to disk before processing, so ingest stays fast even under load. No external services, no per-event pricing.

  • Groups errors into issues with first/last seen timestamps and regressed status
  • Alerts, weekly digest email, and a live SSE event stream
  • Multi-project support with per-project API keys and source map upload
  • SDKs for TypeScript (Node + browser), Python, and Go

FunnelBarn

Self-hosted web analytics and funnel tracking without the cookies.

FunnelBarn is a single Go binary that collects page views, tracks funnels, and attributes traffic to UTM campaigns. All without cookies or third-party scripts leaving your infrastructure. Sessions are fingerprinted server-side from IP and User-Agent, keeping visitor data off the client entirely.

  • Privacy-first: no cookies, server-side session fingerprinting
  • Funnel analysis and A/B test result analysis
  • UTM attribution dashboard for campaign tracking
  • SDKs for JavaScript (browser + Node.js), Python, and Go

GitHub Tamagotchi

A virtual pet for your GitHub repos.

GitHub Tamagotchi hatches a virtual pet from your repository and ties its mood to your commit activity, PR throughput, and issue resolution. It is a playful way to keep an eye on project health, and a surprisingly effective motivator to keep shipping.

  • Pets evolve through lifecycle stages from egg to adult as projects mature
  • Mood reflects real repo activity: commits, PRs, and issue resolution
  • MCP integration lets you check on your pet from your code editor
  • Leaderboard to compare your repo pets with others
