RETRO//CAPTURE · v1

Real traffic in. Replayable chains out.

A free desktop sniffer and mobile companion for RETRO//STRESS. Pick any running process, capture its live traffic, and turn it into a replayable protocol chain you can fire from the cloud.

HOW IT WORKS

Three steps to a live stress test

Quick Test mode handles all three in a single click — or drive each step yourself.

01
CAPTURE

Pick any running process. Capture its live TCP / UDP / ICMP traffic from any interface, tagged to the source PID.

02
BUILD

Auto-parse the PCAP into a .chain file — a replayable protocol script (TCP handshake, TLS, HTTP/2, custom payloads) ready for the stress engine.

03
DEPLOY

Fire the chain at your target from the RETRO//STRESS server fleet. Tune duration, concurrency, and geolocation, then launch from desktop or phone.

CLIENTS

One toolkit, every surface

Native apps for desktop and mobile, plus a headless CLI. Everything talks to the same /api/capture endpoints with your RETRO//STRESS token.

Desktop App

Go / Wails v2 desktop client for Windows, macOS, and Linux. Full packet capture pipeline with process-to-connection mapping.

  • Process table with live connection counts
  • PCAP export + chain generation (exact or templated mode)
  • Quick Test: capture → upload → launch in one click
  • Requires libpcap (Linux / macOS) or Npcap (Windows)
Windows macOS Linux

CLI (Bubbletea TUI)

The same capture + chain pipeline wrapped in a Bubbletea terminal UI — perfect for VPS boxes, SSH sessions, or headless servers.

  • Single Go binary, no GUI dependencies
  • Same /api/capture endpoints, same chain format
  • Drop-in on any Linux / macOS host with CAP_NET_RAW
Linux macOS SSH / VPS

Mobile App

React Native / Expo app. Link your account via deep link, manage favorites, and fire saved chains from your phone.

  • OAuth-style deep-link account linking
  • Favorites saved per-process for one-tap launches
  • Concurrent fan-out of N parallel tests
Android iOS
THE .CHAIN FORMAT

Real packets, replayed exactly

Every capture produces a .chain file — a compact protocol script the RETRO//STRESS engine replays step-by-step against your target. TCP handshakes, TLS 1.3, HTTP/2 streams, and custom payloads all preserved from the real session.

Capture engine libpcap / Npcap
Chain format .chain (versioned)
Protocols TCP / UDP / ICMP / HTTP/S
Execution Distributed fleet
Auth Bearer token
SAFE BY DEFAULT

Private captures, your account, your targets

Local capture

Packets stay on your machine. Only the generated .chain file is uploaded — never raw PCAPs.

Plan-aware

Advanced chain launches require an eligible plan. Free accounts can still capture and save chains.

Revocable tokens

App tokens are separate from your login. Revoke any linked device from your dashboard at any time.

Zero-log policy

Same privacy policy as the rest of RETRO//STRESS — no activity logs, no target history retention.
