If your company has more than a handful of engineering teams, you've probably hit this problem: nobody can answer "how many services do we actually run, who owns each one, and are they following our standards?" without asking around in Slack. An internal developer portal solves this by automatically building a catalog of every service, then scoring each one against rules you define — is it on the latest runtime, does it have on-call coverage, is it SOC 2 compliant. Cortex and Port are two of the leading tools in this space, and — unusually for competitors — they list each other directly as alternatives in their own product data. That's how similar their pitch is on paper. Here's where they actually differ.
The short version
Cortex leads with measurement: it auto-maps your services into a catalog and leans hard on scorecards to enforce production-readiness, compliance and (new in 2026) how much your teams are actually using AI coding agents. It's built for engineering leaders who want hard data on service quality across a large org, and it's certified SOC 2 Type 2 and ISO 27001, with Fortune 500 customers to show for it. Port leads with self-service automation: golden-path workflows, approval-gated infrastructure provisioning, and AI agents that can resolve tickets and remediate incidents on their own. It's also explicitly positioned as faster to stand up than a self-built Backstage instance — Port claims about a week versus months.
Cortex: measurement-first, enterprise-proven
Cortex automatically maps a company's services into a catalog and a context graph, then uses scorecards to track production readiness, compliance and reliability with real data pulled from your systems, not self-reported checklists. Its newest scorecards specifically measure AI coding agent adoption and impact across teams — useful if your leadership is asking "are we actually getting value from Copilot/Cursor/etc." and wants a number, not a guess. There's no public pricing — Cortex is enterprise-only and requires booking a demo.
Pick Cortex if: you're a larger organization, need SOC 2/ISO 27001-grade certifications on the vendor itself, and want measurement and scorecards to be the center of the product rather than an add-on.
Port: self-service-first, faster to deploy
Port also builds a software catalog with scorecards, but its emphasis is self-service Actions — workflows with approval gates that let developers provision infrastructure or trigger automation themselves instead of filing a ticket to a platform team. It layers AI agents on top for autonomous ticket resolution and incident remediation, with governance controls. Port has a genuinely usable free tier (up to 15 seats, 10K entities, 500 automation runs/month), then Basic at $30/seat/month and Standard at $40/seat/month with SSO.
Pick Port if: you want transparent, self-serve pricing to start with, care more about golden-path automation than deep scorecarding, and want something running in about a week rather than negotiating an enterprise contract first.
Side-by-side
| Cortex | Port | |
|---|---|---|
| Core emphasis | Scorecards & measurement | Self-service automation |
| Pricing | Custom / enterprise only, demo required | Free tier, then $30-40/seat/month |
| Time to deploy | Not disclosed | ~1 week claimed |
| Compliance certifications | SOC 2 Type 2, ISO 27001 | Not highlighted |
| AI features | AI-adoption scorecards | Autonomous AI agents for tickets/incidents |
| Best for | Large orgs needing proof of service quality | Teams wanting fast, self-serve platform automation |
Verdict
Both tools are, by their own vendors' admission, overlapping heavily in positioning — the choice is more about emphasis than raw features. If you're an engineering leader at a large, compliance-conscious organization who wants hard data on whether hundreds of services actually meet your standards, Cortex's scorecard-first approach and its certifications carry more weight. If you're a platform team that wants developers to self-serve infrastructure changes without waiting on tickets, and you'd rather start on a free tier this week than book a sales call, Port is the more practical starting point. Either way, both explicitly position themselves as faster and cheaper to adopt than building the equivalent on open-source Backstage yourself.
