Backstage is an open platform for building developer portals. Powered by a centralized software catalog, Backstage restores order to your microservices and infrastructure and enables your product teams to ship high-quality code quickly — without compromising autonomy.

Backstage unifies all your infrastructure tooling, services, and documentation to create a streamlined development environment from end to end.

Vite is a build tool that aims to provide a faster and leaner development experience for modern web projects. It consists of two major parts:

A dev server that provides rich feature enhancements over native ES modules, for example extremely fast Hot Module Replacement (HMR).

A build command that bundles your code with Rollup, pre-configured to output highly optimized static assets for production.

Gitpod is an open-source Kubernetes application providing fully-baked, collaborative development environments in your browser - powered by VS Code.

Tightly integrated with GitLab, GitHub, and Bitbucket, Gitpod automatically and continuously prebuilds dev environments for all your branches. As a result, team members can instantly start coding with fresh, ephemeral and fully-compiled dev environments - no matter if you are building a new feature, want to fix a bug or do a code review.

Nerd Fonts patches developer targeted fonts with a high number of glyphs (icons). Specifically to add a high number of extra glyphs from popular ‘iconic fonts’ such as Font Awesome, Devicons, Octicons, and others.

Your new microservice development environment friend. This CLI tool allows you to define a configuration to work with both local applications (Go, NodeJS, Rust or others) and forward some other applications over Kubernetes in case you don't want to run them locally.

A framework for managing and maintaining multi-language pre-commit hooks.

Tilt makes it possible to develop all your microservices locally in Kubernetes while collaborating with your team.
Write a Tiltfile script that describes how your services fit together. Share it with your team so that any engineer can hack on any server. See a complete view of your system, from building to deploying to logging to crashing.

Simple app development & deployment - into any Kubernetes cluster. Draft makes it easy to build applications that run on Kubernetes. Draft targets the "inner loop" of a developer's workflow: as they hack on code, but before code is committed to version control. Using two simple commands, developers can now begin hacking on container-based applications without requiring Docker or even installing Kubernetes themselves.

Engineering managers and maintainers of large code bases are starting to realize the potential of Code as Data or how source code can be treated as an analyzable dataset proving valuable information. Think Business Intelligence and processes optimization based on the source code engineers write, rather than adjacent metrics.

Binci is a utility that allows you to easily containerize your development workflow using Docker. Simply put, it's like having a cleanroom for all of your development processes which contain services (like databases) without needing to setup and maintain these environments manually.

Telepresence, in conjunction with a containerized development environment, gives the developer a fast development workflow in developing a multi-container application on Kubernetes. Telepresence lets you run a Docker container locally, while proxying it to your Kubernetes cluster.

Algorithms study materials, behavioral content and tips for rocking your coding interview. Carefully curated content to help you ace your next technical interview, with a focus on algorithms.

TLA stands for the Temporal Logic of Actions, but it has become a shorthand for referring to the TLA+ specification language and the PlusCal algorithm language, together with their associated tools.
TLA+ is based on the idea that the best way to describe things formally is with simple mathematics, and that a specification language should contain as little as possible beyond what is needed to write simple mathematics precisely. TLA+ is especially well suited for writing high-level specifications of concurrent and distributed systems.

Program the 8086-like microprocessor of a robot in a grid-based multiplayer world. The game is web based so no installation is required.

Neutrino is a companion tool which lets you build web and Node.js applications with shared presets or configurations. It intends to make the process of initializing and building projects much simpler by providing minimal development dependencies.

Software engineering principles, from Robert C. Martin's book Clean Code, adapted for PHP. This is not a style guide. It's a guide to producing readable, reusable, and refactorable software in PHP.

Wick is a free browser-based toolkit for creating small interactive things for the Internet. With Wick, you can create games, animations, and everything in between. Your creations can run on any device with a web browser - that means mobile too. And since Wick lives in the browser, you don't have to download any extra software to use it!

Wick is a hybrid of an animation tool and a coding IDE, heavily inspired by similar tools such as Flash, HyperCard, and Scratch. It was developed in response to a growing need for such a tool for the modern web. You can read more about the creation of Wick here.

A source-control branching model, where developers collaborate on code in a single branch called ‘trunk’ *, resist any pressure to create other long-lived development branches by employing documented techniques, avoid merge hell, do not break the build, and live happily ever after.

Phoenix is a web development framework written in Elixir which implements the server-side MVC pattern. Many of its components and concepts will seem familiar to those of us with experience in other web frameworks like Ruby on Rails or Python's Django.

Phoenix provides the best of both worlds - high developer productivity and high application performance. It also has some interesting new twists like channels for implementing realtime features and pre-compiled templates for blazing speed.
