AI Analysis
●●SolidSolve My ProblemSlick
PR comments with proto schema diffs is genuinely useful for gRPC teams.
Strengths
- •buf build pipe integration means zero config for existing proto workflows
- •Proto diff detection catches breaking changes before merge
- •GitHub Pages deployment creates living documentation automatically
Weaknesses
- •Only 2 stars—very early, unproven at scale
- •Niche audience limits broader adoption potential

Post Description
Hi HN, I built Coral to solve a pain point I had with large gRPC/Connect projects where proto dependencies became hard to track.
It parses FileDescriptorSet from `buf build` and generates:
- Interactive React Flow graph with a neon-style dark UI - PR comments showing proto schema diffs (added/removed/modified) - Static GitHub Pages for team documentation
Available as both a CLI tool and a GitHub Action:
buf build -o - | coral serve
Live demo: https://daisuke8000.github.io/coral/ GitHub Action: https://github.com/marketplace/actions/coral-proto-visualize...Similar Projects

Create a clean tree graph of your projects with my App on iOS
The app turns projects into draggable node graphs with color tagging, visible dependency links, and progress indicators — exactly the kind of direct-manipulation UI people who think visually will enjoy. The developer highlights a local-first stance (no data collected) and the screenshots show fast node creation and on-canvas editing, but the idea is familiar territory (mind-mappers and visual planners already cover this space) so it needs a unique workflow or integrations to stand out.
