proxy

headroomlabs-ai/headroom

Shrinking AI agent context without losing the important lines — Headroom compresses tool outputs, logs, and RAG chunks before they hit the LLM, cutting tokens by 20% for coding agents and up to 95% for JSON while preserving exact answers, including critical lines like error messages. It ships as a Python/TS library, proxy, or MCP server, with its own kompress-v2 model on Hugging Face.

Compress tool outputs, logs, files, and RAG chunks before they reach the LLM. 20% fewer tokens for coding agents, 60-95% fewer tokens for JSON, same answers. Library, proxy, MCP server.

mitmproxy/mitmproxy

The toolkit for intercepting, inspecting and scripting HTTPS traffic — mitmproxy offers three interfaces—console (mitmproxy), CLI (mitmdump, like tcpdump for HTTP), and web UI (mitmweb)—for intercepting SSL/TLS traffic across HTTP/1, HTTP/2, and WebSockets. It's built for penetration testers and developers who need to inspect, modify, or script HTTP traffic interactively.

An interactive TLS-capable intercepting HTTP proxy for penetration testers and software developers.

XTLS/Xray-core

Xray-core keeps pushing censorship-resistant proxying forward — Xray-core is the engine behind Project X, bundling protocols like VLESS, VMess, Trojan and REALITY for anti-censorship networking. Active development includes post-quantum encryption for VLESS and XHTTP as a REALITY successor, making it relevant for anyone building or running proxy/VPN tooling that needs to evade deep packet inspection.

Xray, Penetrates Everything. Also the best v2ray-core. Where the magic happens. An open platform for various uses.

songquanpeng/one-api

A unified OpenAI-style gateway for dozens of LLM providers — One API lets you call OpenAI, Azure, Claude, Gemini, DeepSeek, ChatGLM, Ernie Bot, Qwen and more through a single standard OpenAI API format. Ships as a single binary with a Docker image for one-click deployment, aimed at teams needing centralized key management and resale of model access.

LLM API 管理 & 分发系统，支持 OpenAI、Azure、Anthropic Claude、Google Gemini、DeepSeek、字节豆包、ChatGLM、文心一言、讯飞星火、通义千问、360 智脑、腾讯混元等主流模型，统一 API 适配，可用于 key 管理与二次分发。单可执行文件，提供 Docker 镜像，一键部署，开箱即用。LLM API management & key redistribution system, unifying multiple providers under a single API. Single binary, Docker-ready, with an English UI.

v2fly/v2ray-core

The community-driven continuation of V2Ray's proxy toolkit — V2fly maintains the V2Ray core after the original project stalled, supporting VMess, VLESS, Shadowsocks, Trojan and Socks5 protocols. It's built for users and developers who need configurable network tools to secure connections and bypass censorship, with active packaging and translation efforts.

A platform for building proxies to bypass network restrictions.

bettercap/bettercap

A multi-protocol recon and MITM toolkit spanning WiFi to CAN-bus — Bettercap combines 802.11, BLE, HID, CAN-bus, IPv4 and IPv6 reconnaissance and man-in-the-middle attacks in one modular tool. It suits pentesters and red teamers who need a single framework for spoofing, sniffing, deauth attacks and proxying across very different network types, with active cross-platform CI and Docker support.

The Swiss Army knife for 802.11, BLE, HID, CAN-bus, IPv4 and IPv6 networks reconnaissance and MITM attacks.

dstotijn/hetty

An open-source MITM proxy for bug bounty workflows — Hetty is an HTTP toolkit with a MITM proxy, request/response interception, and a client for replaying traffic, aimed at infosec and bug bounty researchers. It's positioned as an open-source alternative to commercial tools like Burp Suite Pro, with project-based storage and scope management, and is under active development.

An HTTP toolkit for security research.

Shopify/toxiproxy

Deliberately break your network to prove resilience in tests — Toxiproxy is a Go TCP proxy controlled via HTTP that lets you inject latency, downtime, and other faults into connections during testing and CI. Shopify has run it in all dev and test environments since 2014. Useful for anyone writing tests that must prove an app survives dependency failures.

:alarm_clock: :fire: A TCP proxy to simulate network and system conditions for chaos and resiliency testing

warp-tech/warpgate

A single bastion for SSH, RDP/VNC, HTTPS, Kubernetes and databases — Warpgate is a transparent bastion host for SSH, HTTPS, Kubernetes, MySQL, PostgreSQL, RDP and VNC that needs no client app or SSH wrapper. It records every session for live viewing and replay in a built-in web UI, and offers browser-based access while still supporting native clients. Useful for teams wanting centralized privileged access control across many protocols.

Fully transparent SSH, HTTPS, Kubernetes, database and RDP/VNC bastion/PAM that doesn't need additional client-side software

superdesigndev/treg

A shared gateway that lets agents call thousands of paid APIs per request — Treg is a proxy and registry that gives AI agents one base URL and token to reach a curated catalog of provider endpoints, billed per call instead of per subscription. Teams can also register their own keys, skills and CLIs, shared across agents without exposing credentials. Self-hostable, with a hosted version at treg.to.

Mag1cFall/AIStudio2API

Turn Google AI Studio's web UI into a multi-provider API — A Go proxy that converts Google AI Studio's Playground and Build web protocol into OpenAI, Anthropic and Gemini compatible APIs. It supports multi-account concurrency, dual WAA backends via Camoufox or pure Go, agent clients like Claude Code and Codex, plus Nano Banana, Veo and TTS features, with a dashboard for accounts, usage and logs.
