Perry vs Static Hermes
Perry and Static Hermes both explore ahead-of-time JavaScript/TypeScript compilation, but they have different runtimes, toolchains, target goals, and maturity. Static Hermes remains an active branch of the Hermes project; Perry ships a pre-1.0 CLI and platform stack.

Static Hermes nedir?
Hermes is Meta's JavaScript engine for React Native. The Static Hermes work lives on the static_h branch and includes an AOT-oriented runtime and compiler implementation; its own project discussion describes documentation and implementation as ongoing work.
Perry nedir?
Perry parses TypeScript and JavaScript with SWC and compiles supported code ahead of time through LLVM. Native builds do not require an external Node.js installation or JavaScript engine, but they do statically link the Perry runtime and garbage collector. Perry is pre-1.0, implements a practical language and Node.js subset, and offers an optional embedded V8 fallback for code that needs engine semantics.
Yan yana
| Özellik | Perry | Static Hermes |
|---|---|---|
| Compiler path | SWC → Perry HIR → LLVM | Hermes Static H compiler/runtime branch |
| Runtime | Perry runtime + GC | Static Hermes runtime |

Perry'i ne zaman seçmeli
Choose Perry when its current CLI, target matrix, and UI stack match a product you can validate today.
Static Hermes'i ne zaman seçmeli
Evaluate Static Hermes when React Native/Hermes integration or compiler research is the primary goal and building from its current source workflow is acceptable.
Karar
Neither project should be reduced to an unsupported 'production versus research' slogan. Evaluate the current branch, tooling, semantics, and target needed by your application.
