MMU (Make Me Unicorn) Build Log

From sourcing 534 SaaS launch checklist items to feature-flagged accuracy, PLG share design, security, and monitoring — the build log of a solo OSS.

About this series

MMU (Make Me Unicorn) standardizes 534+ SaaS launch items into an open-source CLI. This build log is honest about where those 534 came from, how accuracy was tightened, and what constraints a one-person OSS actually operates under.

Most useful for solo builders shipping their own OSS or SaaS, ops leads evaluating checklist-based tools, and PMs thinking about OSS governance, security, and observability together.

The order — sources → feature flags → PLG share design → security and monitoring — mirrors the actual build timeline. Read it against the same stage of your own project and the weak stage tends to surface.
