Opencode not respecting NO_PROXY variable

[anand2312]

Description

Running behind a corporate proxy, I have set the HTTP_PROXY, HTTPS_PROXY and NO_PROXY variables as described here

HTTP_PROXY=http://proxy.org.com
HTTPS_PROXY=http://proxy.org.com
NO_PROXY=*.org.com,localhost,127.0.0.1

I need the proxy variables set so that the global npm registry is accessible to install opencode's necessary plugins from, BUT I need opencode to connect to a local LiteLLM proxy as the LLM provider, running on (say) litellm.org.com:4000. My org requires that internal traffic should not be sent through the proxy, which is why I have *.org.com in my NO_PROXY. This setup works for every other application I use (including claude code)

Opencode seems to be routing the requests to LiteLLM also through the proxy, the log files include the error message that my org's proxy returns when you try reaching some internal endpoint through it.
Removing the HTTP_PROXY/HTTPS_PROXY in turn ends up working, but is just a band-aid fix

The key difference in your issue (#8822) is the specific handling of the NO_PROXY environment variable for selective routing, which appears to be not respected even though standard tools handle it correctly.

Feel free to ignore if none of these address your specific case.

Think this is probably a bun bug, ur using the tui right?

Fix available in PR #10856

This issue is addressed by PR #10856 which implements proper NO_PROXY pattern matching.

Your use case:

NO_PROXY=*.org.com,localhost,127.0.0.1

Our implementation supports:

• ✅ Wildcard patterns: *.org.com matches litellm.org.com
• ✅ Suffix patterns: .org.com matches any subdomain
• ✅ Exact match: localhost, 127.0.0.1
• ✅ Domain suffix: org.com also matches sub.org.com

The fix is in packages/opencode/src/util/fetch.ts - we implement our own proxyFetch() wrapper that properly handles NO_PROXY patterns, rather than relying on Bun's native handling.

Note: This is independent of Bun's proxy handling - we explicitly parse and match NO_PROXY patterns before deciding whether to use the proxy.
