PostPlanet: Where Communities Build Living Worlds of Knowledge

Inspiration

Reddit communities are dynamic ecosystems of creativity and curiosity, yet their text-based format limits how we experience collective growth.
PostPlanet reimagines this — transforming subreddit content into interactive, evolving worlds that visually represent community engagement.
Every post, comment, and upvote contributes to shaping a living digital planet.


What It Does

PostPlanet converts subreddit activity into a gamified visualization:

  • Each subreddit becomes a planet.
  • Posts form regions, comments and upvotes drive growth.
  • Milestones trigger events and rewards via Kiro Automations.
  • Users can explore posts, earn badges, and witness their planet evolve in real time.

It’s a new way to see and celebrate community knowledge.


How It Works

  1. Post Mapping: Reddit API data transforms posts into planetary regions.
  2. AI Summaries: Devvit Web’s AI toolkit summarizes posts into “Knowledge Cards.”
  3. Kiro Automations: Engagement milestones trigger events such as “Planet Expansion” or “Festival of Knowledge.”
  4. Gamified Growth: Contributions increase planetary energy, unlocking new features.
  5. Customization: Each subreddit’s planet adopts themes reflecting its identity and flair colors.

Why This Solution Is Needed

Reddit lacks a visual, rewarding way to showcase how communities grow together.
PostPlanet changes that by:

  • Encouraging participation through gamification.
  • Making community contributions tangible and visual.
  • Helping users rediscover old knowledge through exploration.
  • Strengthening the sense of belonging and collaboration.

It turns everyday engagement into a shared adventure.


How It Meets the Hackathon Guidelines

  • Built with Devvit Web: Uses Devvit’s SDK for rendering dynamic subreddit-based experiences.
  • Integrates with Kiro: Leverages Kiro Automations for milestones, badges, and world events.
  • Community-Centric: Every feature enhances interaction and contribution.
  • Innovative Gameplay: Moves beyond leaderboards into interactive storytelling.
  • Scalable Design: Each subreddit operates as an independent planet, enabling ecosystem growth.

Technical Implementation

  • Frontend: React, TypeScript, Devvit Web SDK
  • UI & Animations: TailwindCSS, Framer Motion
  • Logic & Storage: Devvit Storage API
  • Automations: Kiro for badge rewards and global events
  • AI Layer: Devvit AI Summarizer Toolkit
  • Deployment: Vercel or Cloudflare Pages

Challenges

  • Building smooth planetary visualization without performance loss.
  • Balancing aesthetics and readability for multiple subreddit sizes.
  • Ensuring Kiro triggers feel organic and not intrusive.
  • Creating scalable architecture for multi-community usage.

What We’re Proud Of

  • Creating an entirely new visual experience for Reddit engagement.
  • Seamlessly combining AI, automation, and gamification.
  • Fully utilizing Devvit Web and Kiro in a creative way.
  • Delivering a solution that feels like both a game and a community growth tool.

What’s Next

  • Add collaborative missions to unlock new regions.
  • Link multiple subreddits into a Reddit Galaxy.
  • Expand AI summarization and voice interaction.
  • Enable mods to customize planetary parameters and visual themes.

Team Roles

  • Concept & Design: UI/UX, planet metaphor creation.
  • Frontend Development: Devvit Web integration, animation, and rendering.
  • Automation & AI: Kiro workflows, summarization, and reward logic.
  • Testing & Deployment: Performance tuning and hosting.

Conclusion

PostPlanet redefines how communities view themselves — not as threads of text, but as evolving digital worlds shaped by shared contributions.
It captures the essence of the Reddit x Kiro Community Games Challenge — creativity, engagement, and innovation — transforming every user’s action into part of a living universe of knowledge.
