Database & API Visualization

Data & Schema Types

Skip manually drawing table structures or tracing API models. Paste raw configurations in SQL, JSON, YAML, XML, or CSV to instantly generate entity-relationship models and schema maps. We also support expanded data types including JSON Schema, JSONC, JSON5, JSONL/NDJSON, TOON, and TOML. Visualizing structural relationships across complex databases takes only seconds.
