Top use cases
Save the prompts you reuse and regenerate diagrams every time your stack changes.
Show service boundaries and data ownership per domain
Document event flows with schemas and contracts
Highlight synchronous vs async paths for reliability
Expose hotspots and anti-patterns for refactoring
Workflow that ships
Enumerate services, data stores, and event topics. Add throughput and SLAs.
Ask AI to split synchronous calls vs event streams with clear lanes.
Label contracts, schemas, and replay/backfill strategies.
Export to ADRs and incident playbooks with owners.
Prompt recipes
Copy, tweak, and save in your repo so regenerations stay consistent.
"Create a microservices map with domains: checkout, payments, fraud, notifications. Show Kafka topics, retries, and owners."
"Generate an event-driven view separating commands, events, and queries for CQRS."
"Highlight fan-out patterns and where idempotency is required."
Quality checklist
Ownership and domains are visible for every service.
Sync vs async paths are clearly separated.
Contracts and schemas live next to topics/queues.
Backfill/replay strategies are documented.
Why use Datadef
Prompt-to-canvas in seconds
Generate React Flow diagrams from prompts, then tweak nodes, metadata, and z-index with live collaboration.
Always in sync
Save prompts alongside canvas versions so you can regenerate diagrams as schemas, services, or policies change.
Shareable and auditable
Export PNG/SVG for decks, or share live canvases with lineage, SLAs, and runbook links for reviewers.
Built for data teams
Support data mesh, lakehouse, and streaming patterns with typed nodes for tables, pipelines, services, and governance layers.

FAQ
How do I prevent spaghetti diagrams?
Group by domain, show only critical edges, and collapse auxiliary services. Use color to separate sync/async.
Should I show database-per-service?
Yes, if it reinforces ownership. Otherwise, note shared databases as risks to decouple later.
Can AI suggest refactors?
If you provide bottleneck notes, AI can surface candidates like shared databases or chatty sync paths.
