Perry vs Deno
Deno compile produces a standalone executable by bundling a slimmed-down Deno runtime with the program. Perry compiles supported code through LLVM and does not include a JavaScript engine by default, while statically linking its own runtime and GC.

Cos'è Deno?
Deno is a JavaScript and TypeScript runtime with built-in tooling and a permissions model. Its official compile documentation describes a standalone executable that contains the program and a slimmed-down Deno runtime.
Cos'è Perry?
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.
Fianco a fianco
| Caratteristica | Perry | Deno |
|---|---|---|
| Execution model | LLVM ahead-of-time machine code | V8 through the bundled Deno runtime |
| Standalone executable | Target-specific native binary | Program plus slimmed-down Deno runtime |
| Runtime model | Perry runtime + GC statically linked; no JS engine by default | Deno runtime and V8 embedded |
| Permissions | Operating-system process permissions | Runtime permission flags and policy |
| Native UI and mobile | Perry UI targets desktop, mobile, wearable, TV, and Web/WASM | Runtime/CLI/server focus |
| Compatibility | Practical subset; optional V8 fallback | V8 plus Deno, web, and Node compatibility layers |
Dove vince Perry
- +Native-widget UI targets
- +No JavaScript engine in native output by default
- +Mobile, wearable, TV, and Web/WASM target model
- +Small outputs are possible for narrowly linked applications
Dove vince Deno
- +Mature runtime and tooling
- +Granular runtime permissions
- +Broad dynamic JavaScript and package compatibility
- +Built-in formatter, linter, test runner, and related tools
Quando scegliere Perry
Choose Perry for validated native applications where its targets, UI model, and AOT tradeoffs fit the product.
Quando scegliere Deno
Choose Deno for runtime-centric server, CLI, or scripting work where its permissions model, tooling, and V8 compatibility are more important.
Verdetto
Both can ship one file, but one file does not mean the same architecture. Compare your actual application rather than extrapolating from hello world or a microbenchmark.
