Manage your feature flags from Trello using ConfigCat's new Power-Up.

Moving forward with our partnership with @GitHubEducation we have introduced a new plan customized for teachers as part of the GitHub Teachers Toolbox.

ConfigCat Teachers Plan​

You get unlimited ConfigCat Products to make sure there is one for every class, lab and research group each with unlimited Team Members. Also you can add 3 different Permission Groups in every Product to be able to grant proper access rights for everyone.

Focusing on frontend applications, we introduced sensitive text comparators to make sure sensitive info (like email address, username) is kept hidden in targeting rules.

Inspired by Treelon Musk we decided to do our part in the fight against deforestation and climate change. In Nov 2019 we partnered with a non-profit organization MyForest to support local forests by planting trees after every purchase of the ConfigCat service and whenever someone gives feedback.

The main idea about our pricing is that our prices are fixed, deterministic and there are no hidden fees. Also we offer a forever free plan without requiring any commitment or credit card information. All features are available in all plans - even the free - helping the evaluation process of our customers.

There is a way to stream feature flag and configuration changes to the clients right when they happen. In some cases ConfigCat's pull based architecture does not completely satisfies the requirements when microservices need the latest values instantly, or mobile apps where polling sometimes is a battery consuming anti-pattern.

TL;DR​

Your application subscribes to a PubNub channel to get updates about changes. And use ConfigCat Webhooks to notify PubNub when a feature flag value gets updated.

Satisfying the feature request of our customers from the mobile app development industry, ConfigCat now supports semantic version (SemVer) based user targeting. Typical use case where app builders wish to enable or disable features based on the iOS or Android version on the device their app is running on. For example deciding if 2.3.40 is less than or equals 2.30.4 sometimes not that straightforward by only using the traditional < > = comparators.

Show us your most innovative idea in using feature flags with ConfigCat, and we’ll send you a pack of gifts including your choice of video or music streaming worth $100, or books worth $150 + a pack of ConfigCat and GitHub swag + a commercial ConfigCat subscription.

We'd like to make ConfigCat available for as many users as possible. Our SDKs are available in multiple languages. But still lots of our users missed Ruby support in ConfigCat:

• Does configcat have Ruby sdk??
• So I am sad you don’t have a Ruby client I can see.
• Are you planning to support Ruby?

The Ruby SDK​

Finally we decided to create a standalone Ruby SDK.
Ruby is an interpreted language. It's very similar to Python and we already have an SDK written in Python. Taking advantage of this, the first idea was that we simply convert our Python code to Ruby and everything will be just fine.

TL;DR​

If you're a software reseller you are allowed to buy a ConfigCat subscription for your client. You are allowed to resell one subscription to one client only. Of course, you are allowed to resell more subscriptions to the same client.

Here is how to do it.
