Compatibility

Shellroute sets HTTP_PROXY and HTTPS_PROXY for the child process. Whether traffic routes through the proxy depends on the HTTP client.

Works directly

These clients read proxy environment variables by default. No shellroute-specific configuration needed.

Client	Notes
curl	Flags and environment overrides can change behavior.
wget	Reads proxy env vars by default.
Python Requests	Explicit `Session.proxies` can override.
Python HTTPX	Default `trust_env=True`. Set `trust_env=False` to disable.
Python urllib	Default handlers read proxy env vars. Custom handlers can override.
Go http.Client	Default transport reads proxy env vars. Custom transports may not.
Node fetch	Shellroute enables environment-proxy support automatically on supported Node versions. See the canonical matrix for version and opt-out details.

These clients require explicit setup to use the proxy.

Client	Required setup
aiohttp	`ClientSession(trust_env=True)` or explicit proxy configuration.
Playwright	Explicit browser/context proxy configuration.
Puppeteer	Explicit browser/context proxy configuration.
SSH	Use `/ssh user@host` in interactive mode. Direct `ssh` is not routed.

Protocol / Tool	Notes
Raw TCP / UDP / DNS	Shellroute provides an HTTP proxy. These protocols are not routed.

Tool	Notes
npm test / test runners	Depends on the actual HTTP clients used by the test suite. Verify the child client.
