Proxies for Codex CLI: HTTPS_PROXY, the System Proxy Feature, and the Sandbox Network Proxy
How the Codex CLI takes a proxy, from its source and docs: the variables it reads, the system proxy feature, where SOCKS works, and the sandbox network proxy.
Proxies for Gemini CLI: HTTPS_PROXY, MCP Servers, the Sandbox, and No SOCKS5
How Gemini CLI takes a proxy, from its source and docs: the four variables and their order, NO_PROXY, MCP servers, the proxied sandbox, and why SOCKS5 fails.
Proxies for Mistral: Vibe Code, the API SDKs, and the Proxy URL That Chat Apps Ask For
Where a proxy goes for Mistral, from its docs and source: /proxy-setup in Vibe Code, the Python and TypeScript SDKs, local models, regions and the terms.
Proxies for OpenCode: HTTPS_PROXY, the Local Server Exception, and What Bun Does Underneath
How OpenCode takes a proxy, from its docs and source: the variables, the NO_PROXY entry for its own server, company CAs, WebSockets under Bun, gateways.
Proxies for Aider: installing the browser turns your proxy off
Aider's web command has two implementations. One reads your proxy variables, the other passes nothing, and an optional install decides which you get.
Proxies for Kilo Code: the editor knows, the agent does not
VS Code keeps its proxy setting to itself, so spawned processes go direct. Kilo Code forwards it, and one editor setting blanks your shell proxy on purpose.
Proxies for OpenHands: you are reading the wrong repository
The repo with 88,810 stars is now the OpenHands interface. The agent and its browser tool live in a separate SDK, and that tool has no proxy option.
Proxies for Qwen Code: six ways in, and only one wins
Qwen Code takes a proxy from a flag, a settings entry or four environment variables. The first match wins, and it is then used for both schemes.
Proxies for Roo Code: the browser you want to route is gone
Roo Code removed browser use entirely in February 2026, though the dependencies remain. The extension itself needs no proxy code, and here is why.
Proxies for AI Coding Tools: Where Each One Takes a Proxy, With Our Lab Results
Where Claude Code, Cursor, Copilot, Cline, Gemini CLI, OpenCode, Zed and more take a proxy, what our labs found, and where the code they write needs one.
Proxies for Claude Code: HTTPS_PROXY, NO_PROXY and SOCKS, Tested on the CLI
How Claude Code takes a proxy, from the Anthropic docs and our test of version 2.1.283: which variable wins, what NO_PROXY misses, and why a SOCKS URL fails.
Proxies for Cline: VS Code, JetBrains and the CLI, Tested Behind a Proxy
How Cline takes a proxy in VS Code, JetBrains and the CLI, from the Cline docs and our test of CLI 3.0.65: which variables work, no_proxy and SOCKS5.
Proxies for Cursor: The Editor, the CLI and HTTP/2, Tested Behind a Proxy
How Cursor and its CLI take a proxy, from the Cursor docs, forum reports and our tests: HTTP/2 streaming, NO_PROXY, SOCKS5 and the settings to check.
GitHub Copilot Proxy Settings: VS Code, JetBrains, Visual Studio and the CLI
Where GitHub Copilot takes a proxy in VS Code, JetBrains, Visual Studio and the CLI, the rules that hold in all four, and the test that proves a line works.
Proxies for MCP Servers: The Fetch-Heavy Ones Need Residential IPs, and Where the Proxy Goes
An MCP server that fetches the web, a scraper, a search tool, a price checker, hits the same bot walls and per-IP limits as any client, so it needs residential proxies. One that talks only to a private API does not. This covers which MCP servers need a proxy, where it goes in the server, and how to wire it in the common runtimes.
Proxies With the Claude Agent SDK: Proxying the Agents You Build, Not the Model
The Claude Agent SDK is Claude Code as a library, so the agents you build with it browse the web through built-in and custom tools. This guide shows where a proxy goes: in the custom tools and subprocess code that fetch sites, and the process-level HTTP(S)_PROXY for reachability, with the honest note that the SDK's own model calls do not want one.
Proxies that don't die mid-job
Residential, ISP, datacenter and mobile, verified by the same engine that runs tens of millions of checks. They read as a real device and hold up under load. Pay as you go, and your balance never expires. $0.44/GB is the 2,000 GB+ rate; a single gigabyte is $0.50/GB, with no minimum order.
129M+ proxy checks run · 100+ countries · HTTP / HTTPS / SOCKS · re-checked every few minutes · no signup
