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.; ReadMe pricing is per project, so an organisation with several distinct APIs multiplies the monthly bill rather than adding seats, and the sensible workaround, merging unrelated APIs into one documentation project, distorts the information architecture to fit the invoice.
  • They diverge on capability: Backstage covers Software catalogue, ReadMe covers OpenAPI reference.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

Backstage

  • An engineering organisation past roughly a hundred services where nobody can reliably answer who owns a given service at two in the morningnot ReadMe
  • A platform team enforcing golden paths, so a new service is scaffolded with logging, CI and security defaults already wired innot ReadMe
  • A company consolidating scattered READMEs and Confluence pages into docs that live beside the code and cannot silently rot unnoticednot ReadMe

ReadMe

  • Publishing a public API reference where a developer can send a live request with their own key from the documentation pagenot Backstage
  • Cutting support load by showing an integrating developer their own recent failing requests next to the endpoint descriptionnot Backstage
  • Keeping documentation versions aligned with API versions so customers on an older release read the matching referencenot Backstage
  • Shipping documentation from the same pull request as the code change using the rdme command line tool in CInot Backstage

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catalogue is only as good as the YAML descriptors engineers remember to write; without enforcement the register drifts out of date, and a developer portal nobody trusts is abandoned faster than one that never existed.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.

ReadMe

  • Pricing is per project, so an organisation with several distinct APIs multiplies the monthly bill rather than adding seats, and the sensible workaround, merging unrelated APIs into one documentation project, distorts the information architecture to fit the invoice.
  • The metrics and personalisation features require your API to stream request logs to ReadMe, which means production request metadata leaves your infrastructure and needs a scrubbing layer plus a security review before anything is switched on.
  • Single sign-on and private documentation sit on the higher tier, so a company that only needs to gate partner documentation behind SAML pays a large step up for one control.
  • The platform is built for describing REST APIs, and long-form product manuals, internal knowledge bases or non-OpenAPI protocols fit it badly, so most customers end up running a second documentation tool alongside it.
  • Theming is bounded by ReadMe templates and limited custom CSS, so a documentation site that must match a strongly designed marketing site will not get there without compromise.
  • Content uses ReadMe-specific Markdown extensions and platform features, so migrating away is an export plus a rewrite rather than moving a folder of Markdown files.

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.

ReadMe: Is ReadMe priced per user?

No. It is priced per project, meaning per documented API. Team size does not change the bill, and a second API generally does.

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.

ReadMe: Do I have to send my API logs to ReadMe?

Only for metrics and personalised documentation. The reference, guides and playground work without it, but the features that most distinguish the product are the ones that need the log stream.

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.

ReadMe: Can I keep documentation in Git?

Yes. The rdme command line tool synchronises Markdown and OpenAPI files from a repository, so documentation can ship in the same pull request as the code.

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.

ReadMe: Can I self-host it?

No. ReadMe is a hosted product only, so buyers with a hard on-premises requirement need a different platform.
