Your project is scattered across too many tools. Map the chaos on an infinite canvas where notes, files, TO-DOs (and more!) finally live together.

AI Analysis

●●SolidBig BrainDark Horse

Spatial canvas instead of lists, but Miro, Notion, and Linear already own this problem space.

Strengths

•Genuine insight: spatial proximity as cognitive load reduction — mental models do map to layout, not trees.
•Live GitHub sync means project state stays current without manual updates or polling.
•Self-hosted with Docker Compose lowers friction compared to SaaS alternatives for teams hesitant about cloud.

Weaknesses

•Crowded category: Notion, Miro, Linear, Plane all support spatial org + integrations. No killer differentiation yet.
•Early-stage risk: 197 stars, sparse commit history. Unclear if this solves real friction or is neat-looking wireframe.

Post Description

Hi HN,

Ideon is a self-hosted workspace that maps project resources (repositories, notes, links, checklists) on a spatial canvas instead of hierarchical lists.

The goal is to preserve the "mental model" of a project visually, reducing context-switching friction when returning to development after a break.

Stack: - Next.js (App Router) + TypeScript - PostgreSQL + Prisma - Docker Compose for self-hosting - AGPLv3 License

Key features: - Spatial organization of resources (drag & drop blocks) - Direct GitHub integration (live issue tracking on canvas) - Markdown notes with real-time sync - Fully self-hostable

It's designed to run on a cheap VPS or a home server. I'm looking for feedback on the spatial approach compared to traditional linear project management tools.
