SDKs

All three SDKs expose the same programmable sandbox boundary: source, lifecycle, execution, attached processes, files, archive transfer, tunnels, metadata, and typed errors. Mutating RPCs are never retried implicitly.

SDK	Best fit	Async model	Start
Python	Agent tooling, notebooks, orchestration	Sync and asyncio	Python SDK
Go	Services and infrastructure controllers	context.Context	Go SDK
TypeScript	Node.js applications and tools	Promise APIs	TypeScript SDK

Each sandbox selects exactly one source: a template, image, or existing environment. Lifecycle and data-plane operations flow through Axern public APIs; SDKs do not add SSH or shell fallbacks for platform behavior.

The current source release contains all SDKs in the monorepo. Package registry publication is a separate release capability; use the repository examples while evaluating the pre-1.0 API.
