Fscan is an open-source intranet security scanning tool developed as a Go project. It discovers hosts with ICMP probing, scans TCP ports, identifies services and web technologies, performs credential and hash-based authentication tests, detects selected vulnerabilities and unauthorized access, and provides exploitation and local information-gathering modules. Its inputs include IP addresses, CIDR ranges, domains, URLs, and batch files; results can be written as TXT, JSON, or CSV. The tool is organized around service, web, and local plugins. It supports common service fingerprinting, Xray- and Afrog-format web POCs, DNSLog-based detection, HTTP and SOCKS5 proxies, interface selection, rate and timeout controls, independent scan concurrency settings, and configurable exclusions. Its local modules include system and domain information collection, credential acquisition, persistence mechanisms, shells, security-software detection, and log-cleaning utilities. The repository also provides a Go SDK under pkg/fscan for embedding scan tasks in agents or security platforms, with pause/resume control and progress callbacks, plus an optional web management interface enabled through a build tag.

REA is a local reverse-engineering tool for AI agents, distributed as a CLI and MCP server. It connects agents to analysis providers such as Hopper and Ghidra, and can inspect native binaries, macOS applications, JavaScript and Electron applications, .NET assemblies, websites, packages, and controlled runtime behavior. Its investigation workflow decompiles or maps a target, follows strings, symbols, calls, references, and control flow, records evidence and limitations, and uses the findings to help reconstruct features in another project without claiming to recover original source code or automatically clone an application. Analysis runs on the local host; REA configures agent integrations and can optionally install Hopper, while Ghidra and Java must be installed separately. The project is distributed under the MIT license.

Nmap, the Network Mapper, is a network-discovery and port-scanning tool for identifying devices, open ports, operating systems, and services. It can scan targets such as a home-lab network and includes Zenmap as a graphical front end. The project provides source code and binary installers for Windows, macOS, and Linux, and is released under a custom license based on but incompatible with GPLv2; commercial redistribution licensing is also available.

netmon is a self-hosted local-network monitor that periodically measures download and upload speed, ping latency, ISP, and test-server details, then scans the local subnet with nmap ARP scanning to count active devices. It stores the measurements and device counts in a local SQLite database and uses matplotlib to produce 24-hour trend graphs. The monitor sends status updates and periodic reports to Telegram or Discord. Reports can include sarcastic LLM-generated analysis through an OpenAI-compatible API, including a local LLM server. It runs on macOS or Linux, uses Python and uv, and requires system installations of nmap and speedtest-cli; device counting requires passwordless sudo access for nmap.

Reasonix is an open-source AI coding agent built around a local engine and distributed as a self-contained static Go binary. It is designed for DeepSeek, with DeepSeek provided as a preset, while configuration can target OpenAI-compatible endpoints and optionally use separate executor and planner models. The agent can be used through a terminal or desktop app, in a browser, or from an editor through ACP; it provides plan mode, permissions, workspace sandboxing, per-turn checkpoints, and MCP- or extension-based plugins. Its context maintenance is designed around prefix-cache stability, including a stable startup environment summary and pruning of stale tool output before compaction.
