The short version
- Each has a real cost: Backstage backstage is a framework rather than a product: there is no supported turnkey install, so getting to a usable portal means a TypeScript and React project your team owns, hosts and upgrades forever.; MkDocs no built-in versioning, which Docusaurus provides and documentation teams eventually need
- They diverge on capability: Backstage covers Software catalogue, MkDocs covers Plain Markdown.

- A platform team enforcing golden paths, so a new service is scaffolded with logging, CI and security defaults already wired innot MkDocs
- A company consolidating scattered READMEs and Confluence pages into docs that live beside the code and cannot silently rot unnoticednot MkDocs
- A regulated business that needs an auditable register of every running service, its owner and its data classificationnot MkDocs

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Backstage
- Backstage is a framework rather than a product: there is no supported turnkey install, so getting to a usable portal means a TypeScript and React project your team owns, hosts and upgrades forever.
- Upstream releases move quickly and plugin APIs have broken across major versions, so a customised deployment accumulates upgrade debt and teams routinely fall months behind on versions they cannot cheaply catch up on.
- The catalogue is only as good as the YAML descriptors engineers remember to write; without enforcement the register drifts out of date, and a developer portal nobody trusts is abandoned faster than one that never existed.
- Community plugin quality varies sharply, with many unmaintained or pinned to old core versions, so the plugin that made the business case may be the one blocking your next upgrade.
- Spotify Portal, the packaged commercial route, publishes no price at all and is quoted as a custom annual subscription, so the only cost you can actually forecast up front is the self-hosted one, which is the option with the largest hidden staffing bill.
MkDocs
- No built-in versioning, which Docusaurus provides and documentation teams eventually need
- Extending past the theme means writing Python plugins
- Markdown only, so embedding interactive components is not the model

Answered from the vendors’ own pages
Backstage: Is Backstage free?
The project is Apache 2.0 with no licence fee. The real cost is engineering time; teams commonly dedicate one to two engineers permanently to running it.
MkDocs: Is MkDocs free?
Yes, open source under the BSD licence. The Material theme has a free version and a paid Insiders edition.
Backstage: Do I need to write code to use it?
Yes. Configuring and extending a Backstage application is a TypeScript and React project. This is the single most common misjudgement buyers make.
MkDocs: MkDocs or Docusaurus?
MkDocs is simpler and faster to adopt, especially for Python teams. Docusaurus offers versioning, internationalisation and React components, which matter once documentation grows.
Backstage: What is Spotify Portal for Backstage?
A commercial distribution from Spotify with premium plugins and support, generally available since October 2025 and sold as a quoted annual subscription with no published price.
MkDocs: Does MkDocs support versioned docs?
Not natively. Plugins such as mike add it, where Docusaurus includes versioning in core.
Backstage: Who owns the project?
Spotify created and open sourced it; it is now a CNCF project, so the upstream roadmap is not solely Spotify controlled.
