Bots are the future, Microsoft proclaimed at this year’s Build conference, and now the company is inviting developers to submit their own for inclusion in a publicly-available bot directory.

In an email to developers cited on Windows Central, Microsoft said it was seeking submissions of chat bots made using its open-source Bot Framework. The Framework, announced at Build, includes bot builder SDKs for C# and Node.js, available on Github, plus a Bot Connector for connecting your bot to Skype, Slack, Facebook Messenger and other popular conversational channels.

Once the directory goes live—on a yet-to-be-determined date—users will be able to search for and download a range of bots. For now, Microsoft’s directory page includes just a few sample bots released during Build, including a Bing News Bot and one that generates captions for photos. But Microsoft said more than 20,000 developers have already signed up to use the bot framework.
