Your Ultimate Multi-Protocol Communication Workbench
PacketForge is a sleek, modern desktop utility for testing and debugging Serial, TCP, and UDP communication. Designed for embedded engineers, IoT developers, and protocol testers, it provides a unified cockpit to transmit, receive, and analyze data packets in real-time.

|---|---|---|---|---|---|
| Serial | 300 — 3M | 5/6/7/8 | None/Odd/Even | 1/1.5/2 | None/HW/SW |
| TCP/UDP | IP + Port | — | — | — | — |
🗂️ Tabbed Multi-Session Interface
Manage unlimited independent connections in separate tabs. Each tab maintains its own protocol, settings, and data buffers.
⚡ Macro Quick-Send System
Configure up to 12 macro buttons for instant packet transmission. Supports:
- Custom label and hex payload
- Auto-repeat with configurable interval
- One-click activation
🔁 Auto-Send / Repeat
Continuously transmit packets at intervals as low as 1 millisecond for stress testing and timing validation.
📄 HEX & ASCII Display Modes
Toggle between:
HEX— View raw byte values (e.g.,A5 4F 00)ASCII— Human-readable text with escape sequences
📝 Line Ending Options
Choose from
None,CR,LF, orCRLFto match your device's protocol expectations.
📁 Send File
Transmit entire binary files (firmware, hex dumps, scripts) directly over the active connection.
📊 RX/TX Byte Counters
Live counters display total bytes sent and received per session.
📜 File Logging
Automatically log all traffic to a timestamped
.logfile for post-session analysis.
🌗 Dark / Light Themes
Switch between a sleek dark mode and a clean light mode with one click.
📌 Stay on Top
Pin PacketForge above all windows for constant visibility during debugging.
🔄 Auto-Updater
Automatically checks for updates on GitHub and installs the latest version with a single click.
