Project and task management decision
Basecamp
A small team can reproduce most Basecamp workflows (projects, to-dos, message boards, files, calendar) using existing open-source stacks and prior-art repos, but Basecamp’s scale, long-term reliability, and brand/support are durable advantages that are costly to match—so building a narrow replacement is realistic, but fully replacing the commercial offering is not.

Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All Basecamp alternatives, with the arithmetic →
What a replacement has to do
- Create projects, add message threads, create and assign to-dos, upload files, and view project calendar/events.
What it still won’t have
- Decades-scale reliability and operational uptime (99.99% historical uptime)
- Large-file storage at petabyte scale and enterprise storage economics
- Extensive, long-standing customer support and company-run onboarding
- Brand trust and large existing user base
- Polish and integrations provided by Basecamp (native apps, CLI, extensive integrations)
What remains hard
- Infrastructure at scale
More than 5 petabytes of data is stored by Basecamp.
- Brand trust
Over 84 million people have Basecamp accounts.

Runnable build prompt
Build a self-hosted project-management web app using PostgreSQL, a Python (FastAPI) backend, React frontend, JWT auth, and S3-compatible object storage. Implement: user/org auth with guest roles; project pages with message boards (threaded comments); to-do lists with assignees, due dates, and subtasks; file upload/download with previews and searchable metadata; per-project calendar and global calendar aggregation; basic full-text search across messages, files, and to-dos. Exclude: chat presence/real-time cluster chat, mobile native apps, enterprise-grade multi-petabyte storage. Include error handling, input validation, and automated unit and integration tests; provide Docker Compose for local dev and Kubernetes manifests for production.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
