Modern network protocol analyzer built with Rust for maximum performance and reliability.
Rustshark is a production-ready network protocol analyzer that provides deep packet inspection, protocol decoding, and powerful filtering capabilities. Built from the ground up in Rust, it offers Wireshark-compatible functionality with modern architecture and zero-compromise quality standards.
Current Status: v1.0.0 - Production Release (Windows x64)
- Live Packet Capture - Capture from any network interface with BPF filtering
- PCAP Import/Export - Full Wireshark compatibility for offline analysis
- 50+ Protocol Parsers - Ethernet, IPv4, IPv6, TCP, UDP, ICMP, HTTP, DNS, TLS, and more
- Triple-Pane UI - Packet list, protocol detail tree, hex dump viewer
- DuckDB Storage - High-performance database handles millions of packets
- Display Filters - Wireshark-style syntax with protocol, IP, and port filtering
- Examples:
tcp,ip.src == 192.168.1.1,tcp.port == 443 && ip.addr == 10.0.0.1
- Examples:
- BPF Capture Filters - Kernel-level filtering for maximum performance
- Examples:
tcp and port 443,host 192.168.1.1 and not icmp
- Examples:
- Search Functionality - Find packets by text, hex pattern, or protocol fields
- Follow TCP Stream - Reassemble and display bidirectional conversations
- Capture Statistics - Protocol distribution, top talkers, packet rates
- PCAP Export - Save filtered or complete captures for Wireshark
- CSV Export - For Excel, pandas, R analysis
- JSON Export - For APIs, scripts, and automation
- ✅ Validated with 1,000,000+ packet captures
- ✅ Sub-second query performance on 100k+ packets
- ✅ Zero memory leaks in stress testing
- ✅ Production-grade code quality (zero compiler warnings)
Requirements:
- Windows 10 or Windows 11 (x64)
- Administrator privileges (for packet capture)
- Npcap (recommended) or WinPcap
Steps:
- Download the latest release: rustshark-1.0.0-portable-windows-x64.zip
- Extract to any folder
- Run
rustshark.exe - Install Npcap if prompted
- Start capturing!
Linux (.deb/.rpm) and macOS support planned for v1.1.0. Stay tuned!
- Launch Rustshark with administrator privileges
- Select Network Interface from the dropdown
- (Optional) Set Capture Filter
- Enter BPF filter:
tcp and port 443(HTTPS only) - Or leave blank to capture everything
- Enter BPF filter:
- Click "Start Capture"
- Analyze Packets in real-time
- Click "Import PCAP"
- Select .pcap file from Wireshark or tcpdump
- Apply Display Filters to narrow results
- Example:
tcp.port == 80(HTTP traffic)
- Example:
- Search Packets using text or hex patterns
- Export Results to CSV/JSON for further analysis
- Capture or import TCP traffic
- Select any packet from a TCP conversation
- Click "Follow TCP Stream"
- View reassembled bidirectional data
- ASCII text for HTTP, FTP, SMTP
- Hex dump for binary protocols
