Each deep dive is an interactive tour: animated diagrams you step through scene by scene, with a written summary

## One managed heap across languages

[![Interactive tour: One managed heap across languages](https://elide.help/assets/architecture/gc-light.jpg)![Interactive tour: One managed heap across languages](https://elide.help/assets/architecture/gc-dark.jpg)](https://deepdive.elide.dev/gc?source=docs&from=/docs/architecture)

One heap across languages. Two collectors for different workloads: Serial keeps memory use low for CLI tools, desktop apps and low-traffic servers; G1 targets high throughput and short pauses for demanding servers.

## Memory-safe semantics, optimized

[![Interactive tour: Memory-safe semantics, optimized](https://elide.help/assets/architecture/memory-safety-light.jpg)![Interactive tour: Memory-safe semantics, optimized](https://elide.help/assets/architecture/memory-safety-dark.jpg)](https://deepdive.elide.dev/memory-safety?source=docs&from=/docs/architecture)

Elide carries memory-safety checks from the interpreter into optimized machine code, giving guest languages one foundation for safety and performance.

## Native libraries, linked at build time

[![Interactive tour: Native libraries, linked at build time](https://elide.help/assets/architecture/native-substrate-light.jpg)![Interactive tour: Native libraries, linked at build time](https://elide.help/assets/architecture/native-substrate-dark.jpg)](https://deepdive.elide.dev/native-substrate?source=docs&from=/docs/architecture)

Elide ships native transport, cryptography and codecs in one executable. Every guest language shares that foundation.
