Apiome Designer
Draw your domain as a graph of classes — and export OpenAPI, JSON Schema, GraphQL, or SQL from one model.
Apiome Designer is the React Flow schema canvas where teams model their domain as classes wired by $ref and link_def edges. Edit JSON-Schema-style properties with composition and constraints, group classes into color-tagged lanes, freeze immutable schema captures, and round-trip the same project as OpenAPI 3.1, JSON Schema, GraphQL SDL, or SQL DDL through the Canvas | Code toggle.
What ships with Designer
Every Designer surface is wired into the rest of the Apiome platform — no glue code, no separate identity, no bolt-on integrations.
Schema canvas
Model classes as React Flow nodes with dependency edges, a mini-map, and a density toggle.
Class editor
Edit property rows with constraints, composition (allOf, anyOf, oneOf), and conditional logic.
Groups & lanes
Cluster classes by bounded context into color-tagged swim-lanes for readable domain maps.
References & link-defs
Model direct, optional, weak, and bidirectional refs with cardinality and on-delete behavior.
Multi-format code view
Round-trip the project as OpenAPI 3.1, JSON Schema, GraphQL SDL, SQL DDL, or AsyncAPI in Monaco.
Versions & captures
Freeze immutable schema captures, diff to current, and see downstream consumer impact.
A look inside Apiome Designer
Live design previews from the Designer mockup pack — 9 surfaces in total.
Property rows with constraints, composition (allOf/anyOf/oneOf), and conditionals.
Monaco code view diffing OpenAPI/JSON Schema/GraphQL/SQL against the last published version.
Frozen schema_capture timeline with diff to current and downstream consumer impact.
Use cases
Designer is designed around the way real teams actually work — not the way a tool wants them to work.
Map a bounded context of classes and relationships on one canvas instead of scattered schema files.
Design once and export OpenAPI, GraphQL, and SQL DDL from the same source of truth.
Freeze a schema capture and review its diff and pinned consumers before promoting a version.
- Immutable schema_capture history with branch and tag
- Approval gates requiring multiple steward sign-offs
- Downstream consumer impact analysis on every change
- Shared property library with safe rename and drift reports
- Multi-target export with no proprietary lock-in
- Generate a class with properties from a natural-language prompt
- Explain and untangle $ref and link_def graphs
- Spot drift between similar classes and the property library
- Suggest indexes and constraints from usage patterns
A schema co-pilot on the canvas
Designer's Studio AI generates classes from a prompt, explains and repairs reference graphs, spots schema drift, and suggests indexes — all grounded in your live project context.
Every DesignerAI feature is grounded in your tenant's data, runs under your data-residency policy, and respects every role and ACL the platform enforces.
