yolo: A Go repository from Berty Technologies

Yolo is an over-the-air installation distributor for your mobile applications

Multi-platform over-the-air installation aggregator (a TestFlight alternative).

Philosophy

Mobile app development workflows should be as free as possible from corporate ecosystem constraints.

Introduction

Yolo is one-stop realtime feed of ready-to-install releases and tests for your apps. We're using it at berty to make releases and test branches ready to download and use on a developer's device within minutes after passing our CI.

We created Yolo to implement the critical features missing from Apple's TestFlight.

Need	TestFlight	Yolo
Generate artifacts for one build for multiple platforms (e.g iOS, Android)	Write manual custom scripts	Default CI tool aggregator
Writing documentation	Write instructions for each platform	One universal doc
Accessing artifacts across platforms	Use a separate tool per OS	Single aggregated feed
Speedy certificate validation	Run from scratch on eachpublication (~30 minutes)	In-house certificate and signature (~1 minute)
Generate artifacts at any stage of deployment	Stable releases only	Deeply customizable: Merges to master, pending pull requests, specific tags... anything that passes the CI!

Getting started

Official Berty's instance

Nothing to install, using a browser, you can list and download the last builds of applications of the Berty ecosystem.

You just need to have credentials provided by the Berty team and go to https://yolo.berty.io.

Note that all the available credentials won't give you access to the same application set.

Call the official API

Using the same credentials you can make direct calls to the API, available here: https://yolo.berty.io/api/.

The API is described in protobuf-format here: https://github.com/berty/yolo/blob/master/api/yolopb.proto.
