Corridraw — The Innovation Workspace for Teams
An infinite-canvas collaboration SaaS for product, engineering, and design teams — sticky notes, sharp diagrams, live multi-cursor presence, AI-assisted sketch-to-diagram, and embedded boards inside Notion, Linear, and Confluence.
Overview
Corridraw is a live SaaS workspace (corridraw.com) built around an infinite canvas where teams sketch, decide, and ship together — combining a virtualised SVG/Canvas editor, CRDT-backed real-time collaboration, an AI Magic Frame that turns rough sketches into working diagrams, and deep integrations with Notion, Linear, Slack, GitHub, Figma, and Confluence.
Key Features
- Infinite canvas combining sticky notes, freehand ink, sharp shapes, and frames — no grid, no fixed page
- Live multi-cursor presence with names, colours, and conflict-free merging powered by a CRDT document model
- AI Magic Frame — turn a rough sketch into a working flowchart, ER diagram, summary, or component layout
- Smart diagramming for flowcharts, ER diagrams, UML, crow's-foot notation, mind maps, and wireframes with keyboard-first authoring
- Templates library for discovery, retros, planning, roadmaps, architecture, and customer-journey maps
- Threaded comments pinned to elements, async voting, and reactions — decisions live next to the artefact
- Live embeds in Notion, Linear, and Confluence plus integrations with Slack, GitHub, and Figma
- Export to SVG/PNG/PDF with version-history scrubbing backed by an append-only operations log
- 10-second onboarding with a free-forever tier — no credit card required
Architecture
| Component | Details |
|---|---|
| Infinite canvas editor | Custom SVG/Canvas hybrid on React with virtualised rendering, freehand ink, sticky notes, frames, and smart shapes that scale to large boards without dropping frames |
| Diagram engines | Keyboard-driven authoring for flowcharts, ER, UML, crow's-foot, mind maps, and wireframes, sharing the same routing and styling primitives as the freeform canvas |
| AI Magic Frame | LLM-backed service that converts rough sketches and notes into clean diagrams, summaries, and component layouts inside the same canvas context |
| Collaboration gateway | Node.js WebSocket service carrying a CRDT document model so concurrent edits merge cleanly without locking; presence cursors and selection rectangles ride the same channel |
| Auth service | Dedicated NestJS service handling JWT sessions, email verification, workspace-level RBAC, and SSO for paid tiers |
| SSR app | Next.js SSR front-end serving corridraw.com, hydrating the editor, and brokering REST calls to the back-end services |
| Integrations | Notion / Linear / Confluence live-embed renderers, plus Slack notifications, GitHub linking, and Figma frame import |
| Database | PostgreSQL storing documents, workspaces, comments, votes, and an append-only operations log that drives history scrubbing and exports |
| Background workers | Queue-driven workers for thumbnail generation, scheduled PNG/SVG/PDF exports, embed rendering, and analytics roll-ups |
| Infrastructure | Single VPS with separate processes for SSR app, auth service, AI gateway, and WebSocket collaboration server behind nginx with TLS termination |
