Arqonix is an architecture IDE for senior engineers and architects — edit diagrams in code or on canvas, navigate across views with drilldown, and keep your system design in a structured model that can later power AI, code, and documentation.
Work in Mermaid, PlantUML, or visually on canvas. Switch between text and direct manipulation without losing structure.
Your diagrams become a shared internal representation — consistent across views, drilldown paths, and future automation layers.
Use the spec as a foundation for architecture navigation today — and for AI-assisted generation, review, docs, and scaffolding next.
In most teams, diagrams are snapshots. Code evolves separately, architecture drifts, and AI has to guess from incomplete context. Arqonix turns system design into a structured, canonical model — something you can edit, navigate, and build on.
Move across diagrams and levels of detail with drilldown instead of maintaining disconnected files and screenshots.
Most AI tools work on raw text. Arqonix gives them a typed, canonical architecture model to reason over.
Multiple notations and diagram types become views into one model, instead of separate artifacts that drift over time.
Arqonix already gives you a strong core for architecture work today: multi-notation support, direct visual editing, autolayout, drilldown navigation, and a shared internal representation underneath it all.
One internal model with multiple views. Edit in Mermaid, keep structure in canonical JSON, and preserve a stable foundation for future automation.
CoreMove from higher-level architecture into more detailed diagrams. Link views across a project without breaking compatibility with existing notation files.
CoreText editor + live canvas side by side. Edit diagram code directly with instant rendering, syntax-aware workflows, and resilient recovery.
FreeDrag nodes, change layouts, and edit visually on canvas. Updates sync back to source text so visual and textual editing stay aligned.
FreeWork with flowcharts, C4, class diagrams, ER diagrams, and state diagrams with layout support built into the editor experience.
FreeManage multi-diagram projects with IDE-style navigation, tabs, folder structure, and workflows designed for real architecture work.
FreeExport clean SVG output for docs, wikis, and presentations, with structure preserved through the editing pipeline.
FreeUse the built-in markdown renderer to keep architecture and supporting documentation close to the project instead of scattered across tools.
FreeArqonix parses supported diagram languages into a shared canonical representation. This lets you keep compatibility with existing tools while building on a stronger internal model.
Arqonix is already useful today as an architecture IDE. The next layer is AI assistance built on top of the canonical model — not hype first, foundation later.
Live rendering, canvas editing, autolayout, project navigation, markdown rendering, SVG export.
ShippedShared internal representation with Mermaid and PlantUML support as first-class inputs.
ShippedNavigate across C4 layers and linked diagrams, with deeper project-level exploration of architecture views.
In progressAssist with diagram creation, edits, and architecture workflows using the structured spec as context.
NextReview C4 and related views for consistency, completeness, and design quality across the project.
PlannedGenerate scaffolding, contracts, models, and technical docs from the architecture spec once the foundation is ready.
PlannedBPMN and additional system modeling formats integrated into the same IDE and canonical workflow.
PlannedThe core IDE is available now for free. AI features will become a paid layer once they are strong enough to be worth paying for.
