Graphine - Free AI-Powered Online Diagram Editor & Architecture Tool Graphine is a free, browser-based diagramming tool for creating flowcharts, cloud architecture diagrams, network topology maps, and UML. It works entirely in your browser with no installation or signup required. Please enable JavaScript to use the full editor. Design Cloud Architecture at the Speed of Thought Create flowcharts, AWS/GCP/Azure cloud architecture diagrams, and network topology maps with an AI assistant. Import from draw.io, export to Terraform. Free, fast, works offline as a Progressive Web App. What Can You Create with Graphine?

Cloud Architecture Diagrams — AWS, GCP, and Azure service topologies with official provider icons

Flowcharts & Process Diagrams — Standard flowchart shapes with auto-layout and animated edges

Network Topology Maps — Visualize network infrastructure, VPCs, subnets, and routing

System Design & UML — Component diagrams, class diagrams, and data flow via PlantUML

Key Features

AI-powered diagram generation — Create full diagrams from natural language descriptions like "3-tier AWS with ALB, EC2, and RDS"

AWS, GCP & Azure icon libraries — Pre-built service icons for Amazon Web Services, Google Cloud Platform, and Microsoft Azure

Infrastructure-as-Code export — Generate Terraform, Pulumi (TypeScript & Python), AWS CDK, Azure Bicep, and ARM templates from visual diagrams

Import from draw.io & PlantUML — Import .drawio, .puml, .mmd, and JSON files. Export to PNG, SVG, PDF, draw.io, PlantUML, and JSON

Real-time collaboration — Multiplayer cursors, presence, and conflict-free concurrent editing

Version history & visual diffs — Auto checkpoints every 30 seconds, manual snapshots, side-by-side diffs, and one-click restore

Presentation mode — Frame-based slideshow for architecture reviews and stakeholder presentations

Offline-first PWA — Works without internet. IndexedDB auto-save keeps diagrams safe

Templates — AWS 3-tier web application, GCP microservices, Azure hub-spoke network

Sketch mode — Hand-drawn rendering for informal diagrams

Sharing — Password-protected share links with expiration, embeddable iframes for Notion, Confluence, GitHub

Frequently Asked QuestionsIs Graphine free to use?Yes, Graphine is completely free. Core diagramming features — including the drag-and-drop canvas, cloud icon libraries, AI chat, import/export, and offline support — are available at no cost. Optional premium tiers add extended collaboration and storage.What types of diagrams can I create with Graphine?Graphine supports cloud architecture diagrams (AWS, GCP, Azure), software architecture diagrams, flowcharts and process diagrams, network topology maps, UML component and class diagrams, system design diagrams, and data flow diagrams. You can also import PlantUML and Mermaid for sequence diagrams.Can Graphine import diagrams from draw.io?Yes. Graphine imports .drawio files from draw.io / diagrams.net and can export back to draw.io format. It also supports PlantUML (.puml), Mermaid (.mmd), and JSON import/export for full interoperability with existing tooling.Can Graphine generate Terraform or infrastructure-as-code from diagrams?Yes. Graphine generates Terraform, Pulumi (TypeScript and Python), AWS CDK, Azure Bicep, and ARM templates directly from your visual cloud architecture diagrams using AI. The generated code is production-ready and uses the correct resource types for each cloud provider.Is Graphine a good draw.io or Lucidchart alternative?Graphine is a strong free alternative to draw.io, Lucidchart, and Visio. It adds AI-powered diagram generation from natural language, cloud-specific icon libraries, infrastructure-as-code export, real-time collaboration, version history with visual diffs, offline PWA support, and an embeddable viewer — all in the browser with no installation required.Does Graphine work offline?Yes. Graphine is a Progressive Web App (PWA) with service worker caching and IndexedDB auto-save. You can create, edit, and save diagrams without an internet connection. Changes sync to the cloud when you reconnect.Do I need to sign up or create an account?No. Graphine works immediately in the browser with no signup or installation. Optional email/password login enables cloud saving, sharing, real-time collaboration, and version history.Can I share diagrams with people who don't have an account?Yes. You can create password-protected share links with optional expiration dates. Shared diagrams are viewable in any browser without an account, and can be embedded in Notion, Confluence, GitHub, or any page via an iframe.
