Terraform Provider for Azure
Terraform provider for Azure Resource Manager
The AzureRM Terraform Provider allows managing resources within Azure Resource Manager. When using version 3.0 of the AzureRM Provider we recommend using Terraform 1.x. Whilst older versions of Terraform Core (0.12.x and later) remain compatible with v3.0 of the AzureRM Provider. The Azure Provider can be used to configure infrastructure in Microsoft Azure using the Azure Resource Manager API's. We recommend using either a Service Principal or Managed Service Identity when running Terraform non-interactively (such as when running Terraform in a CI server) - and authenticating using the Azure CLI when running Terraform locally. -

sish
HTTP(S)/WS(S)/TCP Tunnels to localhost using only SSH
An open source serveo/ngrok alternative. Builds are made automatically for each commit to the repo and are pushed to Dockerhub. Builds are tagged using a commit sha, branch name, tag, latest if released on main. Each release builds separate sish binaries that can be downloaded from here for various OS/archs. Feel free to either use the automated binaries or to build your own. If you submit a PR, images are not built by default and will require a retag from a maintainer to be built. You can also use Docker Compose to setup your sish instance. This includes taking care of SSL via Let's Encrypt for you. This uses the adferrand/dnsrobocert container to handle issuing wildcard certifications over DNS. SSH can normally forward local and remote ports. This service implements an SSH server that only handles forwarding and nothing else. The service supports multiplexing connections over HTTP/HTTPS with WebSocket support. -

Beads Viewer
Task management system for coding agents
Beads Viewer is a visualization tool designed to display, inspect, and interact with “bead plots,” graphical representations often used in statistical analysis, time series exploration, or clustering visualizations where data points are represented as beads on strands or axes to emphasize patterns and relationships. The viewer provides an intuitive graphical interface that automatically renders bead plots from structured data inputs, enabling users to observe trends at a glance, highlight clusters, or drill down into individual sequences. It supports dynamic interactions such as zooming, filtering by criteria, selecting subgroups, and exporting views for reports or slides. Because bead plots can encode a significant amount of information in compact visuals, Beads Viewer includes customizable styling options — such as coloring by category, adjusting bead size and spacing, and toggling axis representations — to help tailor visuals to specific analytical needs. -

dyff
diff tool for YAML files, and sometimes JSON
A diff tool for YAML files, and sometimes JSON. dyff is inspired by the way the old BOSH v1 deployment output reported changes from one version to another by only showing the parts of a YAML file that changed. Similar to the standard diff tool, it follows the principle of describing the change by going from the input file to the target to the input file. Input files can be local files (filesystem path), remote files (URI), or the standard input stream (using -). -

sh
A shell parser, formatter, and interpreter with bash support
A shell parser, formatter, and interpreter. Supports POSIX Shell, Bash, and mksh. Requires Go 1.16 or later. To parse shell scripts, inspect them, and print them out, see the syntax examples. For high-level operations like performing shell expansions on strings, see the shell examples. shfmt formats shell programs. See canonical.sh for a quick look at its default style. shfmt formats shell programs. If the only argument is a dash (-) or no arguments are given, standard input will be used. If a given path is a directory, all shell scripts found under that directory will be used. When indexing Bash associative arrays, always use quotes. The static parser will otherwise have to assume that the index is an arithmetic expression. Some builtins like export and let are parsed as keywords. A subset of the Go packages are available as an npm package called mvdan-sh. -

BoringSSL
Mirror of BoringSSL
BoringSSL is a Google-maintained fork of OpenSSL, designed specifically to meet the security, performance, and maintainability needs of Google’s infrastructure and products. While fully open source, BoringSSL is not intended for general public use — it serves as a streamlined, heavily modified SSL/TLS and cryptography library optimized for Google’s internal ecosystem, including Chrome/Chromium, Android, and other Google services. The project prioritizes security, simplicity, and maintainability over backward compatibility. Unlike OpenSSL, BoringSSL provides no guarantee of stable APIs or ABIs, meaning third-party projects depending on it may frequently break. Google products that use BoringSSL ship their own copies and update them as needed, enabling faster iteration without legacy constraints. BoringSSL includes comprehensive API documentation, build instructions, and guidance for porting code from OpenSSL. -

Gas Town
Gas Town - multi-agent workspace manager
Gas Town is a sophisticated multi-agent workspace manager designed to orchestrate and coordinate numerous Claude Code agents working on diverse tasks within a shared development environment. It tackles the common challenge where individual AI agents lose context on restart by persisting work state using git-backed hooks, enabling reliable and resumable multi-agent workflows that scale comfortably beyond just a handful of concurrent agents. The system introduces concepts like The Mayor (the primary coordinator agent), Rigs (project containers), Crew Members (developer workspaces), and Polecats (ephemeral worker agents), organizing work into structured convoys and beads that can be tracked through command-line interfaces. By integrating with tools like tmux and supporting git worktrees, Gastown enables interactive sessions where agents and humans collaborate fluidly, with tracked progress, handoffs, and historical records. -

Helmsman
Helm Charts as Code
Helmsman is a Helm Charts (k8s applications) as Code tool that allows you to automate the deployment/management of your Helm charts from version-controlled code. Helmsman uses a simple declarative TOML file to allow you to describe a desired state for your k8s applications as in the example toml file. Alternatively YAML declaration is also an acceptable example YAML file. Helmsman sees what you desire, validates that your desire makes sense (e.g. that the charts you desire are available in the repos you defined), compares it with the current state of Helm and figures out what to do to make your desire come true. -

Netcap
A framework for secure and scalable network traffic analysis
The Netcap (NETwork CAPture) framework efficiently converts a stream of network packets into platform-neutral type-safe structured audit records that represent specific protocols or custom abstractions. These audit records can be stored on disk or exchanged over the network, and are well-suited as a data source for machine learning algorithms. Since parsing of untrusted input can be dangerous and network data is potentially malicious, a programming language that provides a garbage-collected memory-safe runtime is used for the implementation. -

Operator SDK
SDK for building Kubernetes applications. Provides high level APIs
The Operator SDK makes it easier to build Kubernetes native applications, a process that can require deep, application-specific operational knowledge. The Operator SDK provides the tools to build, test, and package Operators. Initially, the SDK facilitates the marriage of an application’s business logic (for example, how to scale, upgrade, or backup) with the Kubernetes API to execute those operations. Over time, the SDK can allow engineers to make applications smarter and have the user experience of cloud services. Leading practices and code patterns that are shared across Operators are included in the SDK to help prevent reinventing the wheel.
