What is MetaMask Flask?

It is a fork of Metamask for developers. It is the canary distribution of MetaMask Extension. It is a parallel distribution with most cutting edge features and ideas. It is intended for developers only. It does not provide the same API or UX stability as the main MetaMask apps, so participation is at our own risk. It is mainly for developers to experiment with new unstable APIs.

When developing an application that maintains and transfers actual money, a secure UX and stable features are essential in protecting the user's assets. One single bug can cost millions of dollars. Developers can eliminate these bugs by launching experimental features in Flask and swiftly iterating on them before releasing them to users.

Pros and Cons

Helps in Better Testing	Unsupervised

Conclusion

With MetaMask Flask, MetaMask enters a new chapter. It is an experimental playground for developers, where new or proposed features can be deployed and tested before being made available to the general public. Metamask Team will work with the community to determine what parts of flask will eventually migrate to production Metamask. This will eventually help in the development of more Dapps.
