Morgenruf is a free, self-hosted Slack standup bot that replaces paid tools like Geekbot ($2.50/user/mo) and Standup & Prosper ($3/user/mo). It collects daily standups via Slack DMs, posts formatted summaries to your channel, and includes mood tracking, analytics, webhooks, and a web dashboard. Open source (MIT), deploy with Docker, Helm, or AWS. Your data stays on your servers — forever.
