kymostudio 0.2.0

Diagram-as-code DSL — declarative architecture diagrams to animated SVG/WebP

kymostudio (Python)

Diagram-as-code: turn a declarative .diagram DSL — or a standard BPMN 2.0 .bpmn file — into animated SVG / WebP (also Figma / Excalidraw).

Install

pip install kymostudio
# or
uv tool install kymostudio

Convert (CLI)

kymo path/to/diagram.diagram              # → path/to/diagram.svg
kymo path/to/diagram.diagram --animate    # → path/to/diagram-animated.svg
kymo path/to/diagram.diagram --figma      # → path/to/diagram.figma.js
kymo path/to/diagram.diagram --excalidraw # → path/to/diagram.excalidraw
kymo path/to/process.bpmn                 # → path/to/process.svg (BPMN 2.0)

See ../../samples/ for complete example .diagram and .bpmn files.

BPMN 2.0 import

A standard .bpmn file (from bpmn.io / Camunda Modeler / Signavio …) renders to SVG using the geometry in the file's Diagram-Interchange section — no layout pass runs. See ../../docs/BPMN.md for the element mapping.

from kymo import parse_bpmn, render

diagram = parse_bpmn(open("process.bpmn").read())
svg = render(diagram)

Python API

from kymo import parse, layout, resolve_alignments, render

diagram, layout_spec, external = parse(open("diagram.diagram").read())
if layout_spec:
    layout(diagram, layout_spec, external)
resolve_alignments(diagram)
svg = render(diagram, animate=True)

uv run --group dev python -m pytest -q       # run the test suite
uv run ../../playground/server.py            # local showcase + playground
