The short version

  • Only GitHub Desktop has a free tier, so it costs nothing to try first.
  • Each has a real cost: Cortex pricing is quote only, so a platform team cannot build a business case or compare against the true cost of self-hosted Backstage without entering a sales cycle first.; GitHub Desktop there is no official Linux build; the application ships for Windows and macOS only, and the community fork at shiftkey/desktop that packages it for Linux is maintained separately and lags official releases, so a mixed-OS team cannot standardise on one client.
  • They diverge on capability: Cortex covers Service catalogue, GitHub Desktop covers Line-level staging.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Cortex

  • Pricing is quote only, so a platform team cannot build a business case or compare against the true cost of self-hosted Backstage without entering a sales cycle first.
  • The catalogue is only as accurate as the metadata you supply, so an organisation with inconsistent repository conventions spends its first quarter cleaning data before any scorecard means anything.
  • Scorecards create political friction: publishing a per-team grade turns an engineering standard into a performance metric, and teams will game the rules rather than fix the underlying issue.
  • It is closed source and hosted, so organisations with strict data residency or air-gap requirements have limited options compared with running Backstage themselves.
  • Value scales with organisation size, so a company with fifty engineers and thirty services will find the catalogue tells them nothing they did not already know while still paying an enterprise contract.

GitHub Desktop

  • There is no official Linux build; the application ships for Windows and macOS only, and the community fork at shiftkey/desktop that packages it for Linux is maintained separately and lags official releases, so a mixed-OS team cannot standardise on one client.
  • Submodules are effectively unsupported: the app shows a submodule change as an opaque single line and gives you no way to initialise, update or navigate into it, so any repository using them needs the terminal anyway.
  • History rewriting is limited to squashing and reordering local commits by drag and drop; interactive rebase, fixup chains, editing an old commit's contents and bisect are all absent, which is exactly the set of operations a beginner needs help with most.
  • Pull request features only exist for GitHub remotes, so a team on GitLab or Bitbucket gets a plain Git client with an empty pull request pane and no review or checks view at all.
  • Commit signing with a key that requires a passphrase generally fails, because the app cannot surface the pinentry prompt, and the resulting error message does not say that is the cause.
  • GitHub staffs it lightly compared with its web and CI products, so long-standing feature requests and bugs sit open for years; if you file an issue you should plan around it rather than expect a fix.

Answered from the vendors’ own pages

Cortex: How is Cortex different from Backstage?

Backstage is an open source framework you build and staff. Cortex is a hosted product with scorecards and initiatives out of the box and no platform team required to keep it running.

GitHub Desktop: Is there a Linux version?

Not an official one. GitHub ships Windows and macOS builds only. A community fork, shiftkey/desktop, produces Linux packages, but it is maintained by volunteers and trails the official releases.

Cortex: Is pricing published?

No. Cortex requires a sales conversation and prepares a custom proposal.

GitHub Desktop: Does it work with GitLab or Bitbucket?

For plain Git operations, yes: you can clone, commit, push and pull against any remote. The pull request, review and checks features only work against GitHub.com and GitHub Enterprise.

Cortex: Can it self-host?

It is offered as a hosted product; on-premise arrangements are handled through sales rather than published.

GitHub Desktop: What does it cost?

Nothing. It is free and the source is published under the MIT licence, and it is separate from any GitHub plan you may or may not pay for.

Cortex: What is the main adoption risk?

Bad or missing service metadata. The catalogue and every scorecard on top of it inherit whatever quality your repositories already have.

GitHub Desktop: Will it handle submodules?

No. Submodule changes appear as an unreadable single-line diff and there are no controls for initialising or updating them. Repositories that use submodules need the command line.

GitHub Desktop: Do I still need to learn Git?

For everyday work, no. For recovery, yes. Anything beyond the curated set of operations, including interactive rebase and reflog recovery, happens in the terminal, so a team using it should have at least one person who knows Git properly.

GitHub Desktop: Does it work with GitHub Enterprise Server?

Yes. It signs in to GitHub Enterprise Server and GitHub Enterprise Cloud as well as GitHub.com, and it honours organisations that enforce SAML single sign-on.
