About Failbook
Every successful developer, creator, and entrepreneur has a hidden graveyard of failed projects. The problem? We usually try to forget them, which means we forget the valuable lessons we paid for with our time and energy.
Failbook changes that.
Failbook is a 100% private, locally stored browser extension designed to help you document the things that didn't work out. By keeping a structured log of your failures, you can identify patterns, stop repeating the same mistakes, and build a personalized playbook for your future success.
🚀 Key Features:
Log the Details: Record the project name, category, metrics achieved, the core reason it failed, and your biggest key learnings.
Visual Proof: Attach screenshots of your dead apps, websites, or analytics dashboards directly to your entries.
Smart Tagging & Search: Add custom tags (like #burnout, #marketing, or #pricing) and use the real-time search bar to instantly filter your graveyard.
Analytics Dashboard: Get a quick birds-eye view of your total failures, your most common failure category, and your most frequently used tags.
100% Private by Design: Failbook has no backend servers and requires no account. Your data is saved locally on your machine using your browser's native storage.
Data Portability: Easily export your entire graveyard as a JSON file for backup, or import past data if you switch computers.
