Architecture diagramsthat think with you.
▎
Built for teams who take architecture seriously
Not just another
diagramming tool
Syncitect combines capabilities that no other architecture tool offers in one place.
Cinematic Snapshot Morphing
Take snapshots of your architecture at any point in time. Then watch the evolution as Syncitect smoothly morphs between versions — nodes glide to new positions, edges rewire, and additions glow in as deletions gracefully fade. It's version control you can see.
- Animated transitions between any two snapshots
- Visual diff — added, removed, and moved elements highlighted
- Scrubable timeline with playback controls
Integrated Architecture Decision Records
Every node, edge, and group can carry inline ADRs — lightweight records of why a decision was made. No more hunting through Confluence or Google Docs. The rationale lives right next to the component it describes.
- Full lifecycle: proposed → accepted → deprecated → superseded
- Record alternatives, rationale, and date — all inline in YAML
- ADRs survive every export and import — they travel with the diagram
Use Kafka over RabbitMQ
Higher throughput for event streaming. Native partition-based ordering guarantees. Better ecosystem for exactly-once semantics.
RabbitMQ (simpler ops), AWS SQS (managed), Pulsar (multi-tenancy).
Live Data Flow Simulation
Click any node and watch data packets cascade through your architecture in real-time. Packets follow edges, respect protocols (gRPC, Kafka, REST), and log every hop in a live timeline. Understand your system's behaviour before writing a single line of code.
- BFS cascade — packets automatically follow all outgoing edges
- Protocol-aware latency — gRPC is faster than REST, Kafka is async
- Speed controls (0.5× – 4×) and full simulation log
Guided Architecture Walkthroughs
Turn any diagram into a narrated presentation. Define stops anchored to nodes or groups, add narration text, and play a guided walkthrough that zooms and pans through your architecture. Perfect for onboarding, design reviews, and stakeholder demos.
- Auto-generate walkthroughs from node order
- Configurable auto-advance with per-stop zoom levels
- Present directly from the canvas — no export needed
Entry point for all client requests. Handles auth and rate limiting.
Orchestrates business logic and dispatches to downstream services.
Async event bus for decoupled communication between services.
Import from Infrastructure
Drop a Terraform folder onto the canvas and watch your entire cloud infrastructure materialize as an architecture diagram. Syncitect parses .tf files, resolves module references, infers edge semantics, and auto-layouts the result — zero configuration.
- Terraform HCL, Mermaid, PlantUML, DOT, Docker Compose, and Kubernetes YAML
- Smart edge inference — "routes to", "encrypts with", "secured by" labels derived from code
- AWS, GCP & Azure icons auto-matched to resources and modules
Everything you need to
architect at scale
From quick sketches to production-grade architecture documentation.
Split-Screen Editor
Write YAML on the left, watch the diagram render in real-time on the right. Every keystroke is instantly visualized.
AI Generation
Describe your architecture in plain English. AI generates the YAML and diagram instantly — then iterate naturally.
Smart Auto Layout
One click to auto-arrange any diagram. Hierarchical, radial, or force-directed — the algorithm picks up your intent.
Import & Export
Import from Terraform, Mermaid, PlantUML, DOT, Docker Compose, or Kubernetes YAML. Export to SVG, PNG, YAML, and more. Drop a folder of .tf files to auto-generate diagrams.
Review & Annotate
Anchor annotations to any element. Move diagrams through a review lifecycle: draft → in-review → approved → archived.
Node Types & Styling
9 node types, 4 edge styles, edge routing modes, custom icons, and groups. Make your diagram match your system's visual language.
YAML in, diagrams out
Write declarative YAML. Get a visual canvas that stays in perfect sync.

Describe, draw, or import
Start with an AI prompt, hand-write YAML, or drop a Terraform folder. Define nodes, edges, groups, and decision records.
Simulate & validate
Fire data packets through your architecture. See where the bottlenecks are before writing code.
Snapshot & evolve
Capture versions. Use cinematic morph transitions to visualize how your architecture evolves.
Review & present
Run guided walkthroughs for stakeholders. Export to SVG, PNG, Mermaid, PlantUML, or share a permalink.
