PRODUCT FEATURES

Built for the developer workflow

Not a relabeled consumer VPN — every layer is tuned for how engineers actually work.

First VPN designed for developers

Engineers are the target from day one: terminal, SSH, containers, IDEs, AI coding agents — every workflow runs on the same lane, not a consumer VPN with a fresh skin.

Whole-system TUN passthrough

Unlike legacy SOCKS / HTTP proxies: terminal git / pip / npm / docker, IDE built-in requests, and SSH tunnels are all captured in one shot — no per-tool proxy config.

Native support for AI coding tools

Claude Code, Codex, Cursor, Copilot, Gemini CLI — they all just work the moment your IDE starts. No HTTP_PROXY, no third-party plugins.

Long sessions never drop

Keep-alive and re-routing tuned for multi-turn agents like Claude Code and Codex — a single session runs uninterrupted for hours or days without breaking.

Zero drop on installs & large downloads

pip install / npm install / pnpm / brew / Hugging Face weights — large long-lived connections finish in one go, with resume on rare drops.

Multi-device, one account

Mac + Windows + Linux online at the same time — switch freely across workstation, server, and laptop with shared config and node state.

Agents That Don't Drop

System-level TUN capture keeps Claude Code and Cursor Agent sessions alive end-to-end.

DEV SCENARIOS

A dev's day is more than IDE + terminal

While NasaCode is laser-focused on Claude Code / Cursor / Copilot / VSCode — one tunnel also keeps every other tab a developer opens before clocking out.

docs

Overseas docs & developer communities

Skim GitHub issues, browse Stack Overflow threads, read official API references — nothing stalls because an image CDN took 30 seconds.

core

AI coding tools, first-class

Claude Code long sessions, Cursor's context completion, Copilot Chat reasoning — the moment your IDE boots it's already on the line. This is what we exist for.

chat

AI chat for research

Brainstorm in ChatGPT's web UI, refine specs with Claude in the browser — shares the same exit IP as your IDE assistant, so one less CAPTCHA per day.

remote

Remote work with overseas teammates

Video standups, shared whiteboards, collaborative docs — stays connected through flaky cafe Wi-Fi long enough to finish a two-hour retro.

chill

Offshore streaming for downtime

After shipping a PR at 3am, pull up YouTube for a conference talk; on the commute, queue an overseas tech podcast — 4K with no buffering.

learn

Learning resources for developers

Coursera lectures, overseas technical newsletters, paid course videos — your self-upgrade time stops being gated by the network.

Deeply Tuned for Every AI Coding Tool

Flip TUN on once — every AI IDE and CLI routes through a stable backbone automatically.

One-click connect is really convenient, no complicated setup needed. Plenty of servers, fast speeds, more than enough for daily use.

Been using it for six months, never lost connection. The relay acceleration technology is indeed much more stable than regular VPNs. Great value.
