The technique of creating specs before implementation that Kiro embodies was used widely internally before Kiro's release, but as a (now former) employee I gained access to the Kiro tool at the same time as the public. Others may have had internal access earlier but I'm not aware of them.
I used Kiro IDE and really liked it. The all you can eat model of LLM usage is very tempting compared to say Cursor. The features in the editor are basically the same.

Haven't tried Kiro CLI.
