Open Source Go Data Management Systems for BSD

assetfinder is a reconnaissance tool designed to discover domains and subdomains associated with a target domain by aggregating data from multiple public sources. It queries services such as certificate transparency logs, threat intelligence platforms, and passive DNS providers to build a comprehensive list of related assets. The tool is widely used in bug bounty programs and penetration testing to map an organization’s external attack surface. It supports optional filtering to return only subdomains, allowing users to focus on specific reconnaissance needs. assetfinder is lightweight and easy to use, typically requiring only a single command to produce results, making it ideal for quick enumeration tasks. Its modular design allows contributors to add new data sources, improving coverage over time.

Arcane is a modern, open-source Docker management platform crafted to simplify container orchestration and service operations with an intuitive interface and broad tooling support. Aimed at developers, sysadmins, and self-hosters alike, Arcane combines both graphical and command-line experiences for discovering, launching, and managing containers, images, networks, and volumes across local and remote environments. It emphasizes usability and accessibility, making it less intimidating than traditional tools like Portainer while still powerful enough for real-world usage, including logs, metrics, and console access for individual containers. The project integrates frontend and backend components that work together to provide a cohesive environment management experience, often packaged to run alongside Docker and Docker Compose setups with minimal configuration.

GA Beacon is a lightweight tracking proxy for pages that can display images but cannot run Google Analytics JavaScript. A page embeds a badge or transparent pixel whose URL identifies the analytics property and a meaningful tracking path. The service receives that image request, generates a visitor identifier, and forwards the hit through the Google Analytics Measurement Protocol. Cookies allow it to distinguish repeat visits without requiring client-side scripts. It can derive paths from referral data and offers several badge or pixel display modes. The public App Engine endpoint is intended mainly for demonstrations and prototypes. For production use, the repository is designed to be forked, customized, and deployed as a privately controlled Google App Engine service.

Open source framework for processing, monitoring, and alerting on time series data. Kapacitor is a real-time data processing engine for monitoring and alerting, specifically designed to work with time-series data from InfluxDB.

Koito is a lightweight, self-hostable collaborative knowledge base and note-taking platform designed to help teams and individuals capture, organize, and link ideas with the reliability of a local or private server rather than relying on managed SaaS tools. It combines concepts from wikis, Zettelkasten systems, and modern note apps by letting you create interconnected notes, bidirectional links, and structured collections that mirror how knowledge naturally grows. The interface supports markdown editing with live preview, tag management, and graph-style browsing so you can explore relationships between pages instead of treating documents as isolated files. Because Koito is self-hosted, you retain ownership of your data and can integrate authentication systems for team access control. It also includes collaboration features like real-time editing or change history, making it suitable for team documentation, research projects, and personal knowledge management alike.

log4jscanner is a filesystem scanner and Go package that helps organizations quickly identify vulnerable Log4j components inside JARs and shaded dependencies. Instead of probing networks, it walks directories and archives, including nested JARs, to find version fingerprints and risky classes associated with the Log4Shell family of issues. The focus on static analysis makes it suitable for container images, build artifacts, and offline systems where active scanning isn’t feasible. Clear, machine-readable output allows the tool to plug into CI/CD checks and fleet-wide inventory jobs. For responders, it reduces time-to-visibility by surfacing exactly which paths and bundles require patching or remediation. It’s a pragmatic addition to defense-in-depth programs that need verifiable evidence of exposure without deploying agents.

timelinize is an open-source tool for creating rich, shareable timelines from structured data sources (like YAML, CSV, or JSON) that helps users transform static event lists into beautiful, interactive narratives suitable for presentations, documentation, or educational displays. The project emphasizes simplicity and flexibility by letting contributors focus on the data — defining dates, labels, descriptions, links, and media — while timelinize handles rendering, layout, and interactivity in a polished browser experience. It supports multiple visualization styles, such as chronological horizontal views and compact vertical modes, so you can tailor output to fit different screen sizes and content density. With automatic linking between events and optional categories or tags, timelines become easier to navigate and filter for large datasets, making this tool practical for history projects, product roadmaps, research archives, or personal journals.
