platformatic/node-caged repository overview

Node.js built with V8 pointer compression enabled, delivering ~50% memory reduction for pointer-heavy data structures.

docker pull platformatic/node-caged:latest
docker run -it platformatic/node-caged node

Floating tags (latest, trixie, slim, alpine) track the highest supported Node.js major (currently 26.x).

Tag	Description
`latest`, `trixie`	Debian trixie, Node.js 26.x (recommended)
`slim`	Minimal Debian trixie-slim, Node.js 26.x
`alpine`	Alpine Linux with musl, Node.js 26.x (smallest)
`26`, `26-slim`, `26-alpine`	Latest Node.js 26.x
`25`, `25-slim`, `25-alpine`	Latest Node.js 25.x
`26.1.0`, `26.1.0-slim`, `26.1.0-alpine`	Pinned 26.x version
`25.6.0`, `25.6.0-slim`, `25.6.0-alpine`	Pinned 25.x version

Data Structure	Standard Node.js	Pointer Compressed	Savings
Array of Objects (1M)	40.47 MB	20.24 MB	50%
Nested Objects (500K)	50.21 MB	24.64 MB	51%
Linked List (500K)	19.08 MB	9.54 MB	50%

Heap limit: 4GB per isolate (main thread + each worker has its own 4GB limit)
Best for: Memory-constrained environments, high-density deployments

Note: The 4GB limit applies per V8 isolate. Using worker threads, you can exceed 4GB total memory (e.g., 4 workers = 20GB theoretical max).

Multi-arch images for linux/amd64 and linux/arm64.
