How it works

One inference. Every language.

TypeMorph runs a single AST pipeline in your browser — no backend, no round-trips. Your schema is inferred once and compiled to all 18 targets simultaneously.

Your schema never leaves your browser — not even the URL you import from (unless you opt in to the proxy)

Four Pillars of Pure Schema Engineering

We cut out the clutter. These four premium workbenches solve 90% of your daily structural bottlenecks.

Paste Once.
Compile Everywhere.

Drop any JSON, YAML, or OpenAPI spec and TypeMorph emits typed code for every language your team uses — simultaneously, in the browser, with no server involved. The Zod output goes beyond types: field names are analysed semantically so email fields get .email(), id fields get .uuid().

• 18 generators from one AST — TypeScript, Go, Rust, Java, Swift, Kotlin, C#…
• Semantic field inference: enums, formats, and constraints auto-detected

Schema Intelligence:
Quality Score & Recursive Types

Paste any JSON, OpenAPI, or JSON Schema and TypeMorph scores it instantly — any-type ratio, naming consistency, format hints, depth. Self-referential types like trees and linked lists are detected automatically and emitted as clean recursive interfaces.

• 100% local rule-based quality scoring (0–100 / A–F)
• Auto-detects recursive types (tree, linked list, graph)

Breaking Change Detector:
Semantic Schema Diff

Paste two versions of a schema side-by-side and get a compatibility score instantly. TypeMorph detects breaking changes (type changes, optional→required, field removals), warnings (required→optional, format changes), and safe additions — across JSON, YAML, OpenAPI, and JSON Schema.

• Compatibility score 0–100 with severity breakdown
• Supports OpenAPI 3.x · Swagger 2.0 · JSON Schema · YAML

Schema Change Impact:
Know What Breaks Before It Does.

Paste a before and after version of your JSON. TypeMorph traces the change through every class in the type graph and shows exactly which output languages need to be regenerated — all in the browser, instantly.

• Visual graph: changed (red) · impacted (orange) · safe (gray)
• 15 language targets checked instantly — no regeneration guesswork

100% Privacy-First Architecture

Your code never leaves your browser. All type inference and code generation runs entirely client-side — no API calls, no upload endpoints.
