Define your data structures once. Automatically propagate type-safe definitions across every project, package, and language in your architecture.
SyncLangs acts as the orchestrator for your entire type system. Modify the source, and our parser instantly propagates updates to every language, project, and package in your infrastructure.
Define all shared structures in one master .syln file.
Automatic mapping to native code across all your codebases.
Compile-time safety verified across your entire architecture.

Define cross-service data contracts that stay synced between Rust, Go, and Python.
Bridge the gap between your Python backend and TypeScript frontend flawlessly.
Maintain a single source of truth for your multi-language public API clients.
Engineered for precision. Built for scale. SyncLangs provides the foundational layer for cross-language type integrity.
Definition once, sync everywhere. A single (.syln) file acts as the source of truth for your entire architecture.
Watch mode detects changes and updates your code across all projects and packages in under 100ms.
Eliminate type drift between frontend, backend, and microservices. If it's in the source, it's in the code.
Generates idiomatic TypeScript interfaces and Python dataclasses that feel like you wrote them yourself.
SyncLangs is a build-time tool. No heavy dependencies or runtime overhead in your production environment.
Built with speed in mind. Efficient parsing and parallel generation ensure your workflow stays fast.

View_Implementation_ExamplesIn modern engineering, duplication is the enemy of reliability. Every time you redefine a structure in a new language, you introduce a point of failure.
"Manual synchronization is not a strategy; it's a technical debt with a 100% interest rate."
SyncLangs standardizes your data contracts into a single immutable truth. A single schema change propagates instantly across every microservice, frontend package, and monorepo project in your entire stack.
