Hey, if you’re knee-deep in building apps but constantly bogged down by scattered service docs, endless YAML tweaks, or just trying to keep tabs on who’s owning what-yeah, we’ve been there. Cortex is solid for centralizing all that chaos into one developer portal, but sometimes it feels a bit rigid, like it’s forcing you into a one-size-fits-all mold. What if you could swap it for something that bends to your workflow, cuts the setup time, and actually boosts velocity without adding more meetings? That’s where these top alternatives come in. We’re talking platforms from leading companies that handle the heavy lifting-think automated scorecards, seamless integrations with your Git repos and monitoring tools, and real-time nudges to keep things humming. In this roundup, we’ll walk you through the standout options, why they might edge out Cortex for your setup, and what makes them tick. No sales pitch, just straight talk from someone who’s migrated a few teams myself. Let’s dive in and find what clicks for you.
1. AppFirst
AppFirst lets developers describe what an application needs – CPU, memory, database, networking, docker image – and then automatically builds the entire cloud environment across AWS, Azure, or GCP. No one writes Terraform, CloudFormation, or even touches security groups; the platform applies tagging rules, monitoring stacks, and cost allocation from day one. Ownership stays with the people who wrote the code, while compliance and audit logs live in a central place.
Switching clouds later means changing one line instead of rewriting everything. Companies run it as SaaS or self-hosted on Kubernetes. A waitlist handles early access right now, with no public trial yet.
Key Highlights:
- Application-first definition instead of infra code
- Automatic security, observability, and tagging
- Works on any major cloud or self-hosted
- Central audit and cost breakdown by app
Pros:
- Zero Terraform or YAML to learn or maintain
- Consistent setup no matter who deploys
- Easy cloud migration down the road
Cons:
- Still in early rollout, some edge cases need tweaks
- Less visibility into raw cloud resources
- Self-hosted needs Kubernetes chops

2. Port
Port builds an internal developer portal where services get registered through YAML manifests that developers already keep in their repos. From there the catalog shows ownership, dependencies, runtimes, and current health scores without forcing everyone into fixed schemas. Scorecards check for missing alerts, outdated libraries, or absent docs and light up red when something slips.
Self-service actions stand out – engineers trigger things like new environments, database migrations, or secret rotations straight from the UI, including async jobs or ones that need manager approval. RBAC ties in cleanly, so on-call folks can grab temporary rights without tickets. A free trial opens the full catalog and basic actions.
Key Highlights:
- Flexible YAML-driven software catalog
- Custom scorecards with automated checks
- Self-service actions including async and approval flows
- Kubernetes object visibility in the portal
- Full API and IaC support for setup
Pros:
- Data model bends to existing workflows
- Handles day-2 operations well
- Ephemeral environments with TTL work out of the box
Cons:
- Still expects YAML manifests in repos
- Advanced UI customizations need developer time
- Some actions require webhook endpoints

3. Backstage
Backstage started life inside Spotify and now lives as an open-source CNCF project that anyone can grab and run. At its core sits a software catalog that pulls in ownership, APIs, and docs from YAML files scattered across repos, then stitches everything into a single portal. Plugins handle the rest – TechDocs for markdown pages, scaffolding templates for new services, or dashboards from existing monitoring tools.
Companies usually deploy it on Kubernetes, tweak the UI with their own branding, and let developers add whatever extra tabs make sense. Nothing is locked behind a paywall; the whole thing stays free and extendable forever.
Key Highlights:
- Open-source software catalog with YAML ingestion
- TechDocs for docs-as-code
- Scaffolder templates for new projects
- Massive plugin ecosystem
- Runs self-hosted on Kubernetes
Pros:
- Complete ownership and no licensing worries
- Grows exactly how the company needs
- Huge community keeps plugins coming
Cons:
- Someone has to own the Kubernetes cluster
- Upgrades can break custom plugins
- Initial setup takes real effort
Contact Information:
- Website: backstage.io
4. OpsLevel
OpsLevel builds a service catalog that automatically discovers microservices from git, Kubernetes, and cloud APIs, then layers on ownership detection and maturity checks. Engineers define reliability rules – like having an on-call rotation or SLOs in place – and every service gets scored in real time. The portal becomes the one place to see what exists, who owns it, and what still needs fixing.
Self-service actions let people spin up preview environments or run migrations without tickets. A free trial spins up the full thing for two weeks.
Key Highlights:
- Auto-discovery from existing tools
- Rule-based service maturity scorecards
- Ownership detection and documentation links
- Self-service action workflows
Pros:
- Finds services nobody knew existed
- Scorecards make standards stick
- Ties nicely into existing monitoring
Cons:
- Rules can feel rigid until tuned

5. Roadie
Roadie takes open-source Backstage, hosts it as a managed service, and adds a few missing pieces like proper RBAC, scorecard frameworks, and on-prem data connectors. Companies point it at their repos, and Roadie handles the rest – updates, backups, scaling, and keeping plugins compatible. The catalog and templates work the same way as vanilla Backstage.
Users get a trial period to kick the tires before committing. It stays useful for shops that love Backstage but don’t want to run Kubernetes themselves.
Key Highlights:
- Fully hosted Backstage instance
- Built-in scorecards and RBAC
- Secure connectors for on-prem data
- Automatic Backstage upgrades
Pros:
- Zero ops overhead for the portal
- Keeps pace with upstream Backstage

Conclusion
Look, if you’re still wrestling with scattered docs, ownership guesswork, and infra tickets that kill your flow, any of these options will feel like someone finally turned the lights on. Some give you a polished catalog and scorecards tomorrow, others let you stay open-source and roll your own, a few just take the whole infra-code nightmare off your plate completely. The right pick usually comes down to how much you hate writing YAML versus how much you hate managing yet another SaaS bill.
At the end of the day, pick the one that gets your developers back to writing features instead of debugging VPC peering or begging for IAM permissions. Try a couple, kick the tires hard, and go with whatever stops the loudest complaining in standup. Your future self will thank you, probably with fewer 2 a.m. pages too.
