Infura provides secure, reliable, and scalable access to Ethereum and IPFS. They provide the infrastructure for your decentralized applications so you can focus on the features.
MetaMask is a bridge that allows you to visit the distributed web of tomorrow in your browser today. It allows you to run Ethereum dApps right in your browser without running a full Ethereum node. MetaMask includes a secure identity vault, providing a user interface to manage your identities on different sites and sign blockchain transactions.
How to use MetaMask: https://blog.ujomusic.com/how-to-use-metamask-for-chrome-f258e6034226 Examples of how to integrate MetaMask: https://github.com/danfinlay/MetaMaskStack​
uPort is an interoperable identity network for a secure, private, decentralized web. uPort provides open protocols for decentralized identity and interoperable messaging that enable trusted source attribution for all web communication. By allowing message recipients to trust message senders without centralized servers, we can create an entirely new framework for building applications.
