The short version

  • Only Backstage has a free tier, so it costs nothing to try first.
  • 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.; Legit Security pricing requires contacting sales, making cost comparison difficult
  • They diverge on capability: Backstage covers Software catalogue, Legit Security covers VibeGuard AI code scanning.
  • 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.

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catalogue is only as good as the YAML descriptors engineers remember to write; without enforcement the register drifts out of date, and a developer portal nobody trusts is abandoned faster than one that never existed.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

Legit Security

  • Pricing requires contacting sales, making cost comparison difficult
  • No published pricing tiers or free tier available
  • Requires integration with existing SAST and SCA tools for full capability
  • Focused primarily on code security within development lifecycle
  • Newer entrant with less market presence than established competitors

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.

Legit Security: What is VibeGuard and how does it work?

VibeGuard is Legit Security's core feature that scans AI-generated code directly within IDEs like GitHub Copilot and Cursor, identifying vulnerabilities before code leaves the developer's editor.

Source
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.

Legit Security: What AI code assistants does Legit Security support?

Legit Security integrates with GitHub Copilot, Cursor, and Claude to scan AI-generated code for vulnerabilities.

Source
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.

Legit Security: How does Legit Security's AI remediation feature work?

The platform uses AI to suggest specific code fixes for identified vulnerabilities and can automatically create tickets in Jira with full context for developers to review and apply.

Source
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.

Legit Security: Does Legit Security support compliance reporting?

Yes, Legit Security automates compliance automation with SBOM generation and can generate compliance reports for security and regulatory requirements.
