Choose an SDK or Package

Use SDKs when you need package-level details after a guide. The Guides section shows task workflows; this section explains package names, install commands, public APIs, runtime requirements, and where each package fits.

Runtime Requirements

Ecosystem	Current package target
Node.js	Node `>=22` for published TypeScript packages that declare an engine.
Python	Python `>=3.12` for published Python packages.
Go	Module paths under `github.com/garudex-labs/caracal/packages/...`; current modules declare Go `1.26` where specified.

Each Go submodule has a path-prefixed release tag at the same commit as the product tag, so an exact Caracal SemVer resolves without a pseudo-version. Adapter availability is intentionally ecosystem-specific; parity covers behavior exposed by all three application facades, not identical framework packages.
