Inspiration
RadDiff was inspired by the growing moderation burden faced by Reddit communities. Moderators spend significant time handling repost spam, duplicate content, low-effort AI-generated posts, and repeated abuse across large communities. Many moderation workflows are still manual, fragmented, and time-consuming.
The goal behind RadDiff was to create a moderation intelligence platform that helps moderators quickly identify suspicious reposts, repeated spam patterns, and harmful duplicate content through a centralized workflow system.
Rather than focusing on flashy automation, RadDiff focuses on practical moderation efficiency, helping moderators make faster and more informed decisions.
What it does
RadDiff is a Reddit moderation intelligence platform built for the Devvit ecosystem.
The platform provides:
- moderation queue management
- similarity and repost analysis
- suspicious content detection
- moderator activity tracking
- moderation analytics
- centralized moderation workflows
Moderators can:
- review flagged content
- compare suspected reposts side-by-side
- view similarity confidence scores
- remove or approve content
- track moderation activity across the platform
The system is designed to reduce moderation overhead and improve moderation consistency across Reddit communities.
How we built it
RadDiff was built using:
- React
- TypeScript
- Vite
- Tailwind CSS
- Devvit CLI architecture planning
- centralized state management patterns
- reusable moderation workflow components
The frontend was designed as a realistic moderation interface inspired by internal admin tools and Reddit moderation workflows rather than generic startup dashboards.
The project architecture separates:
- moderation workflows
- similarity analysis systems
- routing
- state synchronization
- future Devvit integration layers
The application was structured to support future Reddit moderation event integration through Devvit services.
Challenges we ran into
One of the biggest challenges was building stable moderation workflows while keeping the application scalable and responsive.
We encountered:
- state synchronization issues
- routing instability
- runtime rendering bugs
- responsive layout inconsistencies
- balancing realistic UX with limited hackathon time
Another challenge was avoiding generic AI-generated dashboard aesthetics and instead creating a moderation tool that felt practical and believable for real moderators.
Accomplishments that we are proud of
We are proud of:
- building a believable moderation intelligence workflow
- creating an interactive similarity analysis system
- designing a realistic moderation experience
- implementing synchronized moderation state updates
- creating a scalable frontend architecture under hackathon time constraints
We are especially proud that RadDiff feels like a real moderation operations tool rather than a static prototype.

What we learned
During development we learned:
- how moderation workflows operate at scale
- how important state architecture is in frontend systems
- how to design productivity-focused interfaces
- how to structure scalable React applications under time pressure
- how Devvit can support moderation tooling for Reddit communities
We also learned the importance of balancing polish, usability, and technical scope during rapid product development.
What's next for raddiff
Next steps for RadDiff include:
- deeper Devvit integration
- live Reddit moderation event ingestion
- automated repost detection pipelines
- moderator collaboration tools
- subreddit-specific moderation customization
- advanced moderation analytics
- machine-assisted spam detection systems
Future versions of RadDiff aim to provide moderators with faster and more intelligent moderation workflows directly integrated into the Reddit ecosystem.
