we are currently building Walkie, a prototyping tool for Slack bots/integrations.
Slack just featured us in their Best Practices Guide in the API documentation, we couldn’t be happier! We just launched some new features as well, including Sign in with Slack.
You can see all the features here: https://goo.gl/MAVb8m
Next week we are running a Design Sprint to decide on the features we will be prioritising. Your feedback would be invaluable. If you are building for Slack, we would love to hear your thoughts.
Thanks in advance! Daniel
