Hi Product Hunt community!👋 I'm excited to introduce SideCalendar - a timeline that stays at the edge of your screen and grows with you through custom plugins!
What makes SideCalendar special:
Plugin Ecosystem - Create custom JavaScript plugins with our intuitive API, featuring built-in plugins for GitHub activity, RSS feeds, reminders, and more
Online Plugin Market - Browse and install community plugins (coming soon!)
Complete Keyboard Shortcuts - Full keyboard navigation (up/down to select, left/right to navigate, tab to switch, Option+number for quick jump, global hotkeys for instant access)
9 Languages - Supports English, Chinese, Japanese, Korean, German, French, Spanish, Portuguese, Russian
Customizable - Tailor your timeline experience exactly how you want it
Perfect for:
Calendar-driven professionals who rely heavily on calendar management for their daily workflow
RSS enthusiasts who stay informed through feed subscriptions and want them integrated into their timeline
Power users who love crafting personalized information streams and productivity tools
My Story:
I built SideCalendar because I was frustrated with heavy calendar apps that took forever to load just to check what's next. I wanted something lightweight, always there, and infinitely extensible.
The plugin system means you can add anything - from your GitHub activity to custom data sources.
What I'm looking for:
The plugin development experience - Is the JavaScript API intuitive for plugin development?
Which integrations would you find most valuable?
Do you need richer tutorials and documentation?
I believe the best calendar is one that adapts to your workflow, not the other way around. What would you build with SideCalendar's plugin system?
Can't wait to hear your thoughts!
