Atlantis Diagrams
Technical teams frequently struggle to keep software architecture diagrams synchronized with evolving codebases and documentation repositories. Atlantis Diagrams delivers a unified self-hosted workspace that couples code-driven Mermaid.js diagramming with structured Markdown knowledge bases in a responsive web interface. Engineers can compose flowcharts, sequence diagrams, state machines, entity-relationship models, and Gantt schedules using split-view CodeMirror editors with real-time SVG rendering. An integrated version history tracker automatically captures revision checkpoints across the last 15 document states, letting authors compare modifications and restore previous iterations without data loss. The linked notes environment supports rich Markdown editing, LaTeX mathematical formulas, interactive task checklists, tag indexing, and full-text keyword searches across personal documentation libraries. Canvas controls allow users to pan, zoom, inspect individual nodes, and export finalized graphics directly into vector SVG, high-resolution PNG, or printable PDF documents. Storage engines adapt to deployment scale, running on zero-configuration SQLite databases out of the box with optional PostgreSQL, MySQL, and Redis caching layers for high-concurrency environments. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.
Benefits
- Real-Time Split-View Diagram Composition
- Draft and preview Mermaid.js code simultaneously with low-latency CodeMirror syntax rendering, allowing technical architects to iterate on complex system topologies without compilation delays.
- Automated Document State Revision Checkpoints
- Preserve up to 15 granular revision checkpoints automatically during diagram edits, protecting architecture documentation against accidental deletions and providing instant rollback points.
- Interconnected Markdown And LaTeX Knowledge
- Maintain technical specifications alongside architecture diagrams with comprehensive Markdown notes, interactive task lists, and KaTeX mathematical formulas indexed by custom search tags.
- Multi-Format High-Fidelity Asset Exports
- Generate production-ready vector SVG files, high-resolution PNG graphics, and printable PDF documents directly from the canvas for technical presentations, wikis, and design reviews.
Features
- Full Mermaid.js Syntax Engine
- Supports flowcharts, sequence diagrams, class diagrams, state machines, entity-relationship schemas, Git graphs, and Gantt charts with live client-side SVG rendering.
- Interactive Pan And Zoom Canvas
- Navigates large-scale architectural topologies with smooth mouse drag panning, pinch zooming, and node inspection tools powered by Tailwind CSS and Shadcn UI.
- Integrated LaTeX Formula Processing
- Renders complex mathematical equations and scientific notation inside linked documentation cards using embedded KaTeX parsers and structured Markdown code blocks.
- Pluggable Database Storage Drivers
- Persists documents locally in self-contained SQLite files with seamless environment variable switching to PostgreSQL, MySQL, and optional Redis caching clusters.
- Single-Click JSON Backup Migration
- Exports complete diagram libraries, categorized folders, linked notes, and tag hierarchies into portable JSON snapshots for automated offsite backups and migrations.
- Tag-Based Full-Text Document Indexing
- Organizes personal and team diagram collections with custom searchable tags, favorite bookmarks, and instant keyword filtering across all project workspaces.
