Use tool ↗About Draft1
Draft1 turns a written description, or a pasted Terraform file, docker-compose or SQL schema, into a diagram in roughly twenty seconds, and hands back something editable in draw.io rather than a flat image. It covers ER, UML, Kubernetes, network, cloud architecture, flowchart and database diagrams, and can generate accompanying documentation exportable as PDF, DOCX or Markdown. There is a documented REST API with key authentication that creates, lists, retrieves and iterates on diagrams in plain English, so it can run inside a build or a docs pipeline. Draft1 is registered at an address in Paris and operates under French law. Quotas are counted in prompts rather than finished diagrams.

Pros & cons of Draft1
The useful decision here is the output format: a draw.io file you can keep editing, not a PNG you have to regenerate every time something changes. Accepting Terraform, docker-compose and SQL as input means the diagram can be derived from the actual infrastructure rather than someone's memory of it. The documented API with a PATCH endpoint for iterating in plain English makes it viable as a docs-pipeline step rather than a one-off toy.
Pros
- Accepts Terraform, docker-compose and SQL as input, not only prose
- Output opens in draw.io and stays editable rather than being a flat picture
- Covers ER, UML, Kubernetes, network, cloud, flowchart and database diagram types
- Documented REST API with key auth, an OpenAPI spec and an endpoint for iterating on an existing diagram
Cons
- Quotas count prompts, so failed attempts and refinements cost the same as successes
- Only three free diagrams before a card is needed
- Collaboration and GitHub version control are held back for the $99 per user Enterprise tier
- No company registration number published, only a Paris street address in the terms
Best for
- Engineers who need architecture diagrams from Terraform or docker-compose they already have
- Teams keeping diagrams in docs that must stay editable in draw.io
- Anyone automating documentation generation through an API
Not for
- Freehand whiteboarding and collaborative brainstorming
- Teams needing a large template and shape library like a full diagramming suite
Watch out: Prompt-based metering means a diagram that needs five refinements costs five prompts; the 1,000-prompt tier is not 1,000 diagrams.
