Documents and notes decision
Confluence
A small team can reproduce a basic wiki, but Confluence's durable advantages—FedRAMP compliance, large integrations marketplace, and enterprise-grade infrastructure—are expensive or slow to replicate, so keep paying for full Confluence for enterprise needs.

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.
What a replacement has to do
- Create and edit rich wiki-style pages, search and browse content, manage space/page permissions, and view page history/versions.
What it still won’t have
- Enterprise compliance certifications (FedRAMP etc.)
- Large ecosystem marketplace of apps and integrations
- Enterprise-grade, highly-resilient global infrastructure and SLAs
- Years of product polish, templates, and admin tooling
What remains hard
- Compliance and regulation
FedRAMP Compliant solutions for the public sector
- Integration maintenance
Marketplace Connect thousands of apps to your Atlassian products
- Infrastructure at scale
Resilience Enterprise-grade & highly performant infrastructure
First-year cost
No published price
Confluence does not publish a price we could read, so there is nothing to compare against. What building costs is below.

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal self-hosted Confluence-like knowledge workspace using Next.js (React) frontend, Node.js (Express) backend, Postgres for structured data, OpenSearch for full-text search, and S3-compatible object storage for attachments. In scope: WYSIWYG editor that saves pages and revisions, page version history, spaces and per-space permissions, authentication (OAuth + local accounts), attachment upload/download, site-wide search, and a small admin UI for managing users/spaces. Out of scope: marketplace/apps, enterprise compliance (FedRAMP), multi-region HA, and advanced analytics. Include logging, input validation, permission checks, error handling, and automated unit + integration tests; provide Docker Compose and a one-file deploy script and README with setup steps.

- Evidence score26
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.
