Echosim is retiring on April 5, 2021

What's happening, and why? was launched in 2016 to help developers test their skills without access to a physical device. It became a reliable, trusted partner in our skill development journey. Over the past few years, a new crop of tools have emerged that offer more integration, more opportunity, and more features. The testing simulator in the Developer Console emerged with voice and text input, full visibility into the request and response payloads, and even an APL simulator. There are also a large number of external Alexa development tools that provide fantastic experiences for skill building. Though Echosim was still being used, many of these newer tools replaced the functionality that our old friend had offered.

Over time, Echosim has seen fewer and fewer visitors, and many newer Alexa developers have never even heard of it. It is for this reason that we have decided to officially grant Echosim’s request for retirement. We will never forget what an invaluable service it provided over these many years, and wish for retirement to be equally rewarding.

Thank You

Thank you, Echosim, for everything you did for us. You were the initial spark that made everything we do today possible. We wish you the best in your retirement, and hope that the conversations will never stop.

We also want to thank all of the developers that used Echosim over the years. If you are still using Echosim today, we recommend that you check out this video walkthrough of some of the newer tools that are available.

If you have any feedback for us about our tools or technology, you can always reach us through the Contact Us form, in the new Alexa Community Slack, or on Twitter @alexadevs.
