ERD
Compatible with BurntSushi/erd
Pure entity-relationship DSL. `[Person]` then `*name` for keys, `firstName` for fields, `Person *--1 Company {label: "works at"}` for relations. Renders through Graphviz internally, so layout is rock-solid even for 50-entity schemas. The cleanest text-to-ERD pipeline available.
In the same space
Most users come to ERD from dbdiagram.io (ERD), yEd ERD or ERDPlus. Glyph runs this engine in the browser — no install, shareable via URL, exportable to PNG / SVG / PDF / source.
