Open-source alternatives to Wireless

OpenWifi is an open-source implementation of the IEEE 802.11n wireless standard designed for programmable logic. It provides a software-defined radio platform and WiFi baseband processor that implements the physical and MAC layers on FPGA hardware, accompanied by a dedicated wireless driver and toolset for hardware control. The project is distinguished by its deep integration of signal analysis and telemetry, specifically through a framework for capturing channel state information and raw IQ samples. It enables high-precision packet timestamping and cross-layer correlation between physical la

HTTPie is a command-line HTTP client designed for sending requests to web services and APIs. It functions as a terminal-based web client and JSON API interface, allowing users to interact with RESTful services and download remote files directly from the console. The tool simplifies the interaction with APIs through a custom syntax for argument parsing and automatic JSON payload serialization. It includes a request debugger to verify the structure of a request before transmission and uses ANSI-based formatting to display server responses with color and indentation for improved readability.

Pi-hole is a self-hosted network utility that functions as a DNS sinkhole server to provide network-wide ad blocking. By acting as a dedicated network gateway, it intercepts and discards requests for known advertising, tracking, and malicious domains across an entire local network, preventing unwanted content from loading on any connected device. The software operates through a lightweight background daemon that handles high volumes of concurrent DNS queries with minimal resource overhead. It utilizes a host-file injection mechanism to redirect traffic toward its local filtering engine and ap

httpstat is a network latency diagnostic tool and HTTP request performance analyzer. It measures and visualizes the timings of DNS lookups, TCP connections, and TLS handshakes to identify specific network bottlenecks. The project functions as a JSON HTTP metrics exporter and a service level objective validation tool. It compares captured network request timings against predefined performance thresholds to detect violations and can export structured timing and response data in JSON or JSONL formats. The tool provides capabilities for automated API diagnostics and network latency troubleshooti

NFS client library

Simple, native and efficient local ad blocker. Only Bash.

DnsServer is a recursive and authoritative DNS server that provides domain name resolution and zone hosting. It functions as both a recursive resolver, performing iterative lookups across the internet, and an authoritative manager for primary and secondary DNS zones. The system distinguishes itself through high-availability clustering and a programmable HTTP API for automating server configurations and bulk record management. It supports a wide range of encrypted transport protocols, including TLS, HTTPS, and QUIC, and allows for custom functionality via a plugin-based request interception fr

wavemon is an ncurses-based monitoring application for wireless network devices on Linux.

Websocat is a specialized set of command-line tools for WebSocket communication, acting as a client, server, and stream processor. It provides a terminal-based interface for connecting to WebSocket servers, hosting secure WebSocket servers, and bridging data between WebSockets and other network transports. The project distinguishes itself by functioning as a bidirectional network relay, allowing the routing of data between WebSocket streams, TCP sockets, UNIX sockets, and standard system input and output. It includes specialized implementations for SOCKS5 and HTTP proxying, as well as a strea

Blocky is a stateless DNS proxy that functions as a network-wide ad-blocker and content filter. It operates as a single binary or Docker container with no database or persistent state, accepting DNS queries over UDP, TCP, HTTPS, TLS, QUIC, and HTTP/3 through a unified plugin-based query pipeline. The core of the system is a client-group policy engine that assigns devices to named groups and applies per-group blocklists, allowlists, and upstream resolvers, with all configuration changes applied through hot-reloading without requiring a restart. The project distinguishes itself through its modu

Wireshark is a network protocol analyzer and traffic inspector used for capturing and inspecting network traffic. It functions as a packet capture tool that intercepts live data from network interfaces and a TCP/IP dissector that decodes network protocol layers to translate raw binary packets into human-readable fields. The system provides capabilities for protocol stream reconstruction, grouping related packets into cohesive conversations between endpoints. It also operates as a packet file converter, allowing for the reading, modification, and conversion of network capture files across vari

AdGuardHome is a network-wide software solution that provides centralized control over domain name resolution, content filtering, and local network management. It functions as a recursive DNS server and DHCP address server, intercepting network traffic to enforce security policies and block unwanted content across all connected devices. By acting as a central gateway, it ensures that every device on a home or office network benefits from consistent protection and private, authenticated name resolution. The software distinguishes itself through granular client management and robust security fe

Wuzz is an interactive command line HTTP client and request inspector designed for capturing, reviewing, and analyzing outgoing network calls and their payloads. It functions as a terminal-based tool for debugging API issues and testing web endpoints. The tool provides specialized filtering for response bodies, using regular expressions and format-specific query syntaxes tailored for JSON and HTML data. It allows for the persistence of captured requests and responses to disk to facilitate the reproduction of network issues and offline analysis. User settings and default request behaviors are
