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catalogue is only as good as the YAML descriptors engineers remember to write; without enforcement the register drifts out of date, and a developer portal nobody trusts is abandoned faster than one that never existed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

Celonis

  • Celonis does not publish pricing on their pricing page or website
  • Company directs customers to contact sales team for pricing information
  • No indication of pricing tiers, starting prices, or quote-based model on public pages
  • Pricing inquiry requires using a contact form or reaching out directly

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.
