webhook
webhook is a lightweight incoming webhook server to run shell commands
...For example, if you're using Github or Bitbucket, you can use webhook to set up a hook that runs a redeploy script for your project on your staging server, whenever you push changes to the master branch of your project. If you use Mattermost or Slack, you can set up an "Outgoing webhook integration" or "Slash command" to run various commands on your server, which can then report back directly to you or your channels using the "Incoming webhook integrations", or the appropriate response body.
