PCAPdroid - network monitor is a privacy-first, open-source Android app designed to analyze and manage device network traffic without requiring root access. By simulating a local VPN, it captures app connections in real time, offers traffic blocking, PCAP file exports, and HTTPS decryption. Ideal for both tech enthusiasts and privacy-conscious users, it combines powerful packet inspection with user-friendly controls.
Features of PCAPdroid - network monitor:
1. Traffic Capture Without Root: Uses a local VPN to monitor app traffic, eliminating the need for device rooting.
2. Advanced Traffic Analysis: Inspects HTTP/HTTPS requests, extracts metadata (SNI, DNS queries, IPs), and displays payloads as hex/text.
3. PCAP Export & Real-Time Streaming: Dumps traffic to PCAP files for tools like Wireshark or streams data to remote receivers.
4. Firewall & Blocking Rules: Block apps, domains, or IPs (paid feature) and filter traffic to spot anomalies.
5. HTTPS Decryption: Decrypts TLS traffic and exports SSLKEYLOGFILE for deeper analysis.
6. Offline Geolocation: Identifies server countries/ASNs using offline databases.
Advantages of PCAPdroid - network monitor:

2. Open-Source Transparency: Auditable code ensures trust and community-driven improvements.
3. No Root Required: Simplifies setup while maintaining functionality.
4. Versatile Export Options: PCAP files, live streaming, and metadata extraction cater to advanced users.
5. Malware Detection (Paid): Integrates third-party blacklists to flag suspicious connections.
Disadvantages of PCAPdroid - network monitor:
1. Complex for Beginners: Steep learning curve for non-technical users.
2. Limited Free Features: Firewall and malware detection require a paid upgrade.
3. Battery Drain: Continuous VPN use may impact battery life.

Development Team:
PCAPdroid is developed by an independent, privacy-focused team committed to transparency. The project’s open-source nature fosters community collaboration, with updates and troubleshooting managed via Telegram. Their emphasis on local data processing and anti-censorship tools reflects deep expertise in network security.
Competitive Products:
- NetGuard (Firewall): Offers app-level blocking but lacks PCAP export and traffic decryption. Simpler UI but closed-source.
- Wireshark: Industry-standard for packet analysis but requires root or tethering on mobile. Less mobile-friendly.
- NoRoot Firewall: Lightweight traffic filtering but no advanced features like HTTPS inspection or malware detection.
Market Performance:
PCAPdroid is highly rated (4.5/5) on F-Droid and GitHub for its unique capabilities, though smaller user bases limit mainstream visibility. Users praise its privacy focus but note the interface could be polished. Downloads are niche, primarily appealing to developers, researchers, and privacy advocates.
