Thought I would add to this thread to help out anyone else looking.
Here is the editor and response from support.
Hi Justin
There are a few different ways.
One you can use our cli (https://webtask.io/docs/wt-cli), wt edit will open the editor. You can read about it in the linked page.
You can also use the make url, https://webtask.io/make will bring you into the editor to create a new task. This is not currently listed anywhere. We are doing an overhaul of our docs and it will be there.
Thanks!
Glenn
