Feature Flags and Dynamic Configuration are the control panel at the heart of your systems. This quarter, Prefab has been focussed on giving you the visibility and control you need to confidently operate your system.

Slack Integration​

This was hands down the #1 customer request we had and we were so happy to build it. Having passive visibility into what features are being turned on/off is fabulous and Slack is the perfect place for it.

It's awesome to be able to easily stay abreast of what's happening, and celebrate or ask questions in comments / emojis. πŸŽ‰πŸŽ‰πŸŽ‰πŸŽ‰

Percent Rollouts​

Dynamic configuration systems like Prefab give you the ability to roll out changes very carefully. What could be more careful than only rolling out a change to 1% of users / deployments? Well, Prefab customers like a small blast radius and asked for the ability to rollout to .1% and we're excited to get that in your hands, along with a much better user experience.

You can never be too careful when switching over to the new Redis cluster.

Ratio-nal Thinking​

But that's not all. Have you ever had a 3-way experiment and felt a deep underlying dissatisfaction with having to roll it out 33% 33% 34%? Same!

Well, suffer no longer, because Prefab is happy to support your rational number brain. Just click "split evenly" and you'll the equivalent of a perfect 1/3, 1/3, 1/3 split (at least as far as floating point numbers can take us).

With friendly descriptions of the change, and the ability to see the state of your flags or config at any point in time, you can feel confident that you know exactly what's happening in your systems.

Restore / Rollback​

Make a mistake? From the audit trail you can now easily click Restore and you'll revert to a previous known-good state of your configuration.

Easy Rollbacks
