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.; Selenium flaky tests are the standing complaint: explicit waits and synchronisation are the tester’s job, where newer tools handle it automatically
- They diverge on capability: Backstage covers Software catalogue, Selenium covers W3C WebDriver.

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 Selenium
- A platform team enforcing golden paths, so a new service is scaffolded with logging, CI and security defaults already wired innot Selenium
- A company consolidating scattered READMEs and Confluence pages into docs that live beside the code and cannot silently rot unnoticednot Selenium
- A regulated business that needs an auditable register of every running service, its owner and its data classificationnot Selenium
Selenium
- Cross-browser testing where Safari and legacy browsers must be coverednot Backstage
- Teams whose test suites are written in Java or C# rather than JavaScriptnot Backstage
- Distributing a large suite across a grid of machinesnot 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catalogue is only as good as the YAML descriptors engineers remember to write; without enforcement the register drifts out of date, and a developer portal nobody trusts is abandoned faster than one that never existed.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.
Selenium
- Flaky tests are the standing complaint: explicit waits and synchronisation are the tester’s job, where newer tools handle it automatically
- Setup involves drivers, versions and grid infrastructure that Playwright and Cypress bundle away
- Slower to run than tools that talk to browsers over a debugging protocol rather than WebDriver

Questions people ask
- Is Backstage or Selenium better?
- Neither clearly leads. Backstage starts at Free and Selenium at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, Backstage or Selenium?
- Backstage starts at Free and Selenium at Free.
- Does Backstage or Selenium run on more platforms?
- Backstage runs on Web, Self-hosted, Linux, Docker, Kubernetes. Selenium runs on Linux, macOS, Windows, Web.
- Can I use Backstage for free?
- Both have a free tier, so you can try either at no cost before committing.
- What is Backstage best used for?
- Backstage is most often used for an engineering organisation past roughly a hundred services where nobody can reliably answer who owns a given service at two in the morning, a platform team enforcing golden paths, so a new service is scaffolded with logging, ci and security defaults already wired in, a company consolidating scattered readmes and confluence pages into docs that live beside the code and cannot silently rot unnoticed, a regulated business that needs an auditable register of every running service, its owner and its data classification. Of those, an engineering organisation past roughly a hundred services where nobody can reliably answer who owns a given service at two in the morning and a platform team enforcing golden paths, so a new service is scaffolded with logging, ci and security defaults already wired in are not what Selenium is typically brought in for.
- What can Backstage do that Selenium cannot?
- Backstage covers Software catalogue, Software templates, TechDocs, Plugin architecture. Selenium covers W3C WebDriver, Many language bindings, Selenium Grid, Broad browser support.
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.
Selenium: Is Selenium free?
Yes, open source with no licence fee. Paid costs come from grid infrastructure or services like BrowserStack.
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.
Selenium: Selenium or Playwright?
Playwright handles waiting automatically and is faster to set up, which removes most flakiness complaints. Selenium wins on language breadth, browser coverage including Safari, and existing suites you already have.
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.
Selenium: Is Selenium still relevant?
Yes. Its WebDriver protocol is a W3C standard implemented by every major browser, and very large existing suites are not rewritten cheaply.
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.
