With cranelift compiler, the total download would be significantly larger. + +² **Wasmer Go Dynamic Linking**: The Go binary dynamically links to `libwasmer.dylib` which must be installed separately or bundled with the application. The binary size increase (159KB) doesn't include the ~40MB libwasmer library.

Total size with compiler would be much larger than our 3.9KB measurement. + +4. **Extism is all-inclusive**: At 21.9MB for Python, it bundles everything needed including native libraries. + +#### Recommendations by Use Case + +- **Self-contained deployment**: Use TypeScript with @wasmer/sdk (12.8MB all-inclusive) +- **Minimal binary size**: Use Go, but plan for libwasmer distribution +- **Python applications**: Install both wasmer and a compiler package, or use wasmtime +- **Plugin systems**: Extism provides the most complete out-of-box experience + +### Platform Considerations + +- **macOS ARM64**: Some SDKs may not have pre-built wheels/binaries +- **Python 3.13**: Newer Python versions may lack wheel support +- **Native Libraries**: Dynamic vs static linking varies by language +- **Lazy Downloads**: Some SDKs download native components on first use + +## Adding New Languages + +To add Ruby or Java support: + +1.
