Hodor vs ByteSniffer

Unlike the majority of system-based HTTP proxy capture software, Hodor is a packet capture tool based on the IP layer protocol. Consequently, Hodor is capable of capturing HTTP data traffic that many other capture software cannot, including the data traffic from Flutter apps. Hodor provides many useful features, including: - Packet capturing & rewriting with support for HTTP, TCP, UDP, and WebSocket data protocols. - Capturing and rewriting Flutter app traffic. - Support JavaScript extensions - HTTPS decryption to view decrypted data. - Mapping (i.e., replacing) data in HTTP requests and responses. - HTTP replaying and simulating requests and responses for server debugging without using the client again. - Formatting preview for Protobuf, Form-Data, JSON, HTML, JavaScript, and CSS. - Forwarding HTTP requests to other network tools within the local network for data processing (including traffic from Flutter apps). - Domain filtering to only view requests and responses from specific domains. - URL Scheme support for controlling the start and stop of packet capturing with commands. Hodor is an incredibly useful web debugging tool that can help you easily resolve various issues, making your work more efficient and enjoyable. Whether you are a developer or a tester, you can benefit from Hodor. Give it a try now! Automatic Subscription Service Rules 1. If you subscribe to the automatic renewal service through your Apple ID and do not actively cancel the automatic subscription service during the subscription period, Hodor will automatically deduct the next subscription fee from the balance of the Apple ID account linked to the automatic renewal service 24 hours before the current subscription period expires (subject to the actual Apple billing rules). You should pay attention to the balance and payment status of the account. If the renewal fails due to account issues or insufficient balance, you will bear the risk and/or loss by yourself. For your convenience, Apple will notify you of the upcoming deduction before processing the payment. It is important to note that based on the nature of the automatic renewal service, if you do not explicitly cancel the automatic renewal service during the subscription period, Apple will issue a deduction instruction to the relevant parties based on your permission. Generally, any fees deducted based on this instruction will not be refunded. 2. Hodor Pro Subscription Period: 1 year. 3. Hodor reserves the right to adjust service prices or stop providing automatic renewal services. If you do not agree with the adjusted service price, you can cancel the automatic renewal service according to these rules. If you do not cancel the automatic renewal service, the subsequent fees deducted by Apple will be adjusted to the new service fee. 4. The method to cancel the automatic subscription service is as follows: open the Apple iOS device "App Store" -> click on the Apple account profile picture in the upper-right corner -> enter "Account" -> click on "Subscriptions" -> select "Hodor" -> cancel the subscription. 5. Hodor may stop providing you with automatic renewal services according to operational needs. Your Hodor service period will end on the date of the expiry of the current service cycle. * Privacy Policy https://ximlu.github.io/hodor/privacy_en.html * Terms of Service https://ximlu.github.io/hodor/terms_en.html

ByteSniffer brings professional-grade network packet capture and analysis to iOS. Powered by a local VPN tunnel and a custom protocol parser, ByteSniffer gives you complete visibility into your device's network traffic without sending a single byte to the cloud. Whether you're debugging an API, auditing app behavior, studying network protocols, or testing security, ByteSniffer delivers the raw data you need in a fast, readable interface that will feel immediately familiar to Wireshark users. --- Capture Everything. Inspect Anything. ByteSniffer captures live IP traffic at the transport layer and decodes it in real time: TCP & UDP: Full header parsing with flags, ports, and session tracking DNS: Query and response decoding, QTYPE detection, pointer-compressed name resolution HTTP: Method, URI, headers, and status codes with color-coded request types TLS/SSL: SNI extraction from ClientHello, handshake state tracking QUIC: Long-header packet detection on UDP/443 ICMP / ICMPv6: Echo, Unreachable, Neighbor Discovery, and more Everything runs on-device. No proxy required by default. No data leaves your device unless you explicitly export it. --- An Interface Built for Technical Work ByteSniffer's interface is compact, dense, and optimized for scanning large captures fast. If you've used Wireshark, the layout will feel natural from the first launch. Packet List: Live-updating table with timestamp, source, destination, protocol, length, and parsed info. Sort by any column. Auto-scroll during capture or lock the view to inspect. Connection View: Session-grouped view that aggregates packets into flows. See packet count, byte totals, and duration per connection at a glance. Packet Detail: Four-tab deep-dive per packet: Overview, Protocol Tree, Hex Dump, and Payload preview. Inspect raw bytes alongside parsed fields. Stats: Protocol distribution, packet rate over time, top destinations, and top conversations, all computed from your live capture. --- Filter Like a Pro ByteSniffer's display filter system uses a field-based expression syntax inspired by Wireshark. Write expressions using protocol fields, boolean logic, and operators to get to exactly the packets that matter: app_proto == "dns" and ip_dst contains "8.8.8" tcp_flags_syn == true and not tcp_flags_ack == true http_method == "POST" Save named filter presets for repeated workflows. Real-time validation shows match count as you type. --- Export and Share Export your capture in JSON or JSONL format to any destination on your device: Files, Mail, AirDrop, or any app on the share sheet. Export all packets or only the ones matching a filter. Filenames are timestamped automatically. --- Built for: Mobile app developers debugging network calls Network engineers diagnosing connectivity issues Security researchers inspecting TLS handshakes and DNS behavior Developers auditing what data their apps actually send Students and professionals learning networking protocols firsthand --- Privacy by Design All packet data is stored exclusively in a local, sandboxed container on your device. Nothing is uploaded automatically. Nothing is shared with third parties. Captures are cleared when the app closes unless you enable session persistence in Settings. ByteSniffer is intended for authorized testing, debugging, and educational use on your own device or networks you have permission to monitor.
