Hotel is a reverse proxy and process manager for local development. It maps custom local domains and subdomains to specific ports or remote servers, removing the need for manual host file modifications. The project provides a web interface to manage the lifecycle of background processes and application servers. It includes on-demand process activation, which starts and stops servers automatically when accessed via a browser to conserve system resources. The tool generates self-signed SSL certificates to enable encrypted HTTPS connections for local environments. It also supports routing traff

Register is a GitOps domain registrar and subdomain registration service that uses version-controlled configuration files to manage domain ownership and mappings. It functions as a DNS management system and record orchestrator, utilizing JSON-based declarative configurations to programmatically update A, CNAME, MX, and TXT records. The project distinguishes itself through a registration process where domain ownership and subdomain assignments are stored as the source of truth within Git repositories. It includes an automated SSL provisioning tool to configure web servers and security certific

reconftw is an attack surface management framework and reconnaissance workflow orchestrator designed to automate the discovery, mapping, and monitoring of external digital assets. It operates as a modular tool-chain pipeline that coordinates a sequence of security tools to perform intelligence gathering and vulnerability scanning. The project distinguishes itself through a cloud-native deployment model that parallelizes scanning workloads across a fleet of remote VPS instances to bypass local resource constraints. It utilizes container-based environment isolation to ensure consistent executio

Sandstorm is an open-source platform that packages and runs web applications in security-hardened sandboxes on a personal server, functioning as a self-hosted web app operating system. It provides a curated app store where users discover and install sandboxed web applications with one-click ease, while each application runs in an isolated container that uses Linux kernel security features to separate it from the host and other apps. The platform includes a centralized authentication layer so users sign in once and gain access to all installed applications without managing separate accounts per

js.org is a community-maintained domain registry that provides free, short subdomains under the js.org namespace for JavaScript-related projects and personal sites. It operates as a pull-request-based system where developers claim subdomains by submitting changes to a central repository, with approvals typically processed within 24 hours. The service routes subdomains to any hosting provider that supports custom domains through DNS CNAME record configuration. The registry is designed to work seamlessly with GitHub Pages, allowing users to map their sites to custom subdomains by adding a CNAME

Interactsh is an out-of-band security testing framework and interaction server designed to detect vulnerabilities such as server side request forgery and blind injections. It functions as a multi-protocol interaction collector that captures DNS, HTTP, and SMTP requests to verify outbound communication from remote applications. The project provides a self-hosted interaction gateway for managing unique payloads and gathering network interactions across multiple domains. It distinguishes itself through the ability to simulate various network protocols and response behaviors, including the routin

Findomain is a subdomain enumeration and infrastructure analysis tool designed for attack surface mapping. It functions as a DNS reconnaissance suite that discovers subdomains using multiple data sources and API keys to identify the full extent of a target network. The system acts as an attack surface monitor by tracking subdomain changes over time and sending real-time alerts via webhooks when new assets are detected. It includes specialized capabilities for detecting DNS wildcards to filter false positives and resolving subdomain IPs through parallel resolution. The tool provides a workflo
