1 • React Native

React Native enables you to build world-class application experiences on native platforms using a consistent developer experience based on JavaScript and React. The focus of React Native is on developer efficiency across all the platforms you care about – learn once, write anywhere. Facebook uses React Native in multiple production apps and will continue investing in React Native.

2 • free-for-dev

Developers and Open Source authors now have a massive amount of services offering free tiers, but it can be hard to find them all in order to make informed decisions.
This is list of software (SaaS, PaaS, IaaS, etc.) and other offerings that have free tiers for developers.
The scope of this particular list is limited to things infrastructure developers (System Administrator, DevOps Practitioners, etc.) are likely to find useful. We love all the free services out there, but it would be good to keep it on topic. It’s a bit of a grey line at times so this is a bit opinionated; do not be offended if I do not accept your contribution.
You can help by sending Pull Requests to add more services. Once I have a good set of links in this README file, I’ll look into a better layout for the information and links (help with that is appreciated too).

3 • facebook / fresco

Fresco is a powerful system for displaying images in Android applications.
Fresco takes care of image loading and display, so you don’t have to. It will load images from the network, local storage, or local resources, and display a placeholder until the image has arrived. It has two levels of cache; one in memory and another in internal storage.
In Android 4.x and lower, Fresco puts images in a special region of Android memory. This lets your application run faster – and suffer the dreaded OutOfMemoryError much less often.
Fresco also supports:
• streaming of progressive JPEGs
• display of animated GIFs and WebPs
• extensive customization of image loading and display
• and many more!

4 • airbnb / javascript

A mostly reasonable approach to JavaScript

5 • gizak / termui

Go terminal dashboard. Inspired by blessed-contrib, but purely in Go.
Cross-platform, easy to compile, and fully-customizable.

6 • ConnorAtherton / loaders.css

Delightful and performance-focused pure css loading animations.

What is this?

See the demo

A collection of loading animations written entirely in css. Each animation is limited to a small subset of css properties in order to avoid expensive painting and layout calculations.


HTML GL solves “the slow DOM problem” by creating WebGL representations of DOM elements and hiding actual DOM after. This speeds up HTML/CSS animations and transformations by using 3D hardware acceleration and allows to apply OpenGL effects as modern 3D games have.

• [Theory behind HTML GL]

Using HTML GL you still work with HTML/CSS as you are common to, but DOM elements are just facades to their WebGL represenations. These GPU accelerated textures are very effective from resources consuming perspective and are very cheap to transform or animate.

Echo is a fast HTTP router (zero memory allocation) + micro web framework in Go.

9 • google / yapf


Most of the current formatters for Python — e.g., autopep8, and pep8ify — are made to remove lint errors from code. This has some obvious limitations. For instance, code that conforms to the PEP 8 guidelines may not be reformatted. But it doesn’t mean that the code looks good.

YAPF takes a different approach. It’s based off of ‘clang-format’, developed by Daniel Jasper. In essence, the algorithm takes the code and reformats it to the best formatting that conforms to the style guide, even if the original code didn’t violate the style guide. The idea is also similar to the ‘gofmt’ tool for the Go programming language: end all holy wars about formatting – if the whole code base of a project is simply piped through YAPF whenever modifications are made, the style remains consistent throughout the project and there’s no point arguing about style in every code review.

The ultimate goal is that the code YAPF produces is as good as the code that a programmer would write if they were following the style guide. It takes away some of the drudgery of maintaining your code.

10 • thampiman / reverse-geocoder

A Python library for offline reverse geocoding. It improves on an existing library called reverse_geocode developed by Richard Penman.

UPDATE (30-Mar–15): v1.2 released with Python3 support and more accurate geocoding! See release notes below.
