Describe your system. OrgGen draws it.
Génère des diagrammes d'architecture (C4, microservices, infrastructure cloud) depuis une description ou un repo. Export Mermaid C4 et PlantUML round-trippable. Connecté à Claude Desktop via MCP : ton agent IDE peut mettre à jour le diagramme en même temps que ton code.
10 ready-made archetypes
Services, datastores, queues, gateways, lambdas, batch, CDN, cache, networks, external — each type has its own icon, shape, and matching connectors. You describe, OrgGen chooses.
5 connection types
Sync (HTTP/gRPC), async (queue), DB (R/W), event (stream), data (S3/files). Each type has its own visual style so the diagram reads at a glance.
Cloud metadata
Cloud provider (AWS / GCP / Azure / on-prem), region, capacity, public access. Everything is stored, everything is exportable, everything feeds into generation.
Mermaid C4 & PlantUML export
Generate Mermaid for your README, PlantUML for your Confluence wiki. Lossless round-trip: you can re-import the exported file later.
Drivable via MCP
Connect Claude Desktop / Cursor to your OrgGen project via MCP. Your agent can add a microservice or change a dependency by reading your code, without leaving the IDE.
Live, collaborative canvas
Every edge stays strictly orthogonal (never diagonal). Deterministic auto-layout, manual drag & drop, real-time sync via Supabase. Several people can edit the same schema.
Prompts to try
