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
Trello
- Free tier limited to 10 boards and 10 collaborators per workspace
- Free tier automation capped at 250 monthly Butler runs
- No offline access; web-based platform requires internet connection
- Advanced views (timeline, table, dashboard) not available on Standard plan
- SSO only available on Enterprise plan

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.
Trello: What are the free tier limitations for Trello?
Trello Free supports up to 10 boards per workspace, unlimited cards, 250 monthly Butler automation runs, and up to 10 Power-Up attachments. Limited to 10 collaborators per workspace.
SourceCortex: Is pricing published?
No. Cortex requires a sales conversation and prepares a custom proposal.
Trello: What features are included in the Standard plan?
Standard ($5-6/user/month) adds unlimited boards, custom fields, advanced checklists, 1,000 monthly automation runs, list colors, and calendar view access.
SourceCortex: Can it self-host?
It is offered as a hosted product; on-premise arrangements are handled through sales rather than published.
