After facilitating too many repetitive retrospectives, I built this free tool to generate various retro templates:
https://kollabe.com/tools/generate-retrospective-templateIt offers standard formats (Mad/Sad/Glad, Start/Stop/Continue) and themed templates to keep teams engaged. No login required, works for remote and in-person teams.
What has your experience been with retrospectives? Have you found certain formats particularly effective for developer teams?
