Design systems that think with you.
Grafica is an AI-powered architecture diagram tool for software and engineering teams. Generate software architecture diagrams from a spec, edit them on a live canvas, and get an AI assistant that returns diffs, simulations, and traces — not just chat replies.
Ask Grafica to change, simulate, or explain your architecture. Get back interactive results you can apply, inspect, and iterate on — never a wall of text.
Propose edits as reviewable, line-level diffs. Preview, apply, or selectively cherry-pick — with full version history on the blueprint.
"What if traffic 10×?" Grafica color-codes saturation, surfaces likely failure modes, and recommends nodes to harden — live across the canvas.
Replay a request end-to-end across your architecture with per-hop latency and state — rendered inline with the diagram it runs on.
Versioned like code, documented like a paper, and contract-checked at every edge. Grafica keeps diagram, docs, and data model in sync.
Manual saves, auto-saves, and assistant applies are all tracked. Restoring a version creates a new one — nothing is ever deleted.
One click turns your diagram into a durable README — subsystem decomposition, data flow, API surface, security rationale. Regenerate after every change.
This system is a multi-tenant AWS control plane that orchestrates two long-running workflows: blueprint-to-code generation and code-to-sandbox verification. The existing diagramming product remains the system of record for authoring; this extension ingests structured blueprint snapshots and produces code artifacts plus verification evidence.
Three cooperating planes: an ingestion plane receives blueprint snapshots from the diagramming product; a codegen plane materializes code bundles via an async workflow engine; and a verification plane runs sandboxed deployments on ephemeral AWS accounts.
Attach data schemas, request/response shapes, and protocols to every edge. Validate at design time so no integration surprises later.

}Not a whiteboard. Not a wiki. A living architecture diagram that stays honest as your system changes.
Every node in your architecture diagram carries rich metadata — icon, description, config, tags, and a stable ID — editable in a clean side drawer that stays out of your way.
Paste a spec, a README, or a napkin sketch. Grafica generates a complete software architecture diagram you can edit, version, and export.
Every change — manual or AI-proposed — is a reviewable commit. Branch architecture scenarios, compare design timelines, roll back with one click.
Turn design reviews into experiments. Probe traffic, failure, and cost scenarios on the diagram canvas before anything ships to production.
Wire your traces to nodes. Replay a request across your system architecture diagram with hop-by-hop latency — diagram and observability become one surface.
Connect Claude Code, Cursor, or any MCP-compatible agent to Grafica. Your AI coding assistant reads and updates architecture diagrams as it ships code — diagrams stay in sync without manual effort.
Simple credit-based pricing. AI diagram generations and documentation on every plan.
Grafica is an AI-powered architecture diagram tool for software and engineering teams. It lets you generate, edit, and version-control software architecture diagrams on a live canvas, with an AI assistant that produces interactive diffs, simulations, and trace overlays.
Paste a spec, README, or plain-text description of your system. Grafica's AI generates a complete architecture diagram with typed nodes, edges, and metadata. You can edit the result directly on the canvas, ask the AI to refine it, or export it.
Grafica supports cloud architecture diagrams, microservices diagrams, system design diagrams, infrastructure diagrams, data flow diagrams, and multi-tenant platform architecture. Any technical system your team designs can be modelled on the canvas.
Traditional tools are static whiteboards. Grafica treats diagrams as living, version-controlled models. The AI doesn't just create a picture — it understands node types, dependencies, and relationships, enabling simulations, architecture diffs, and request traces on the same canvas.
Yes. The free plan gives you 3 AI-generated architecture diagrams and 50 lifetime credits with no credit card required. Paid plans start at $29/month for unlimited AI generations and version history.
Grafica can ingest specs, READMEs, and structured descriptions to generate diagrams. Runtime trace overlay lets you wire real observability data to diagram nodes so latency and failures are visible directly on your architecture diagram.
Free for the first three diagrams. No credit card needed.
