Top reasons to use Mr. Senko

Faster response cycle

On average it takes around 20 to 30 days for a single pull request to be accepted on GitHub! Mr. Senko is working on forked repositories and we're able to deliver patches and bug fixes faster.

Regular releases

Open source package authors release new versions when they see fit. Sometimes this takes several months. Mr. Senko provides weekly and bi-weekly package releases for all supported libraries.

Long Term Support

Typically older versions of libraries reach end-of-life when the latest one is released. Mr. Senko takes over maintenance and continues to provide backports, bug fixes and security patches.

Private repositories

Subscriptions map to private URLs which can be used with your package management tools, e.g. pip, bundler, npm. Everything is reliably served from our CDN without downtime or missing older versions.

How it works

  1. Report a problem to Mr. Senko;
  2. Mr. Senko will prioritize, reproduce, test and fix the problem;
  3. Mr. Senko will push the changes to GitHub and create a new package version;
  4. You download and upgrade from a private repository!

One subscription == one priority vote?

Every Monday morning Mr. Senko decides what bugs and feature requests will be included in the next package version. This is based on their severity and demand from developers. If you are developing multiple applications using the same library and want an issue to be fixed faster we ask you to increase the number of your subscriptions! Mr. Senko considers it a good practice to have one subscription per project!
