The short version
- Only Frappe 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.; Frappe the framework is strongly opinionated: its own ORM, templating and job queue mean general Python and Django experience transfers only partly, and onboarding a new developer takes weeks rather than days.
- They diverge on capability: Cortex covers Service catalogue, Frappe covers DocType modelling.
- Prices and features above were last checked on 31 August 2026.

What people use each for
The jobs each tool is most often brought in to do.
Cortex
- A platform team that needs to prove to leadership how far a Kubernetes or framework migration has actually progressed across hundreds of servicesnot Frappe
- An organisation where ownership of production services is genuinely unknown after reorganisations or acquisitionsnot Frappe
- Enforcing production readiness standards on new services at creation time rather than at incident reviewnot Frappe
- Replacing a self-hosted Backstage that is consuming a full-time engineer or two just to stay upgradednot Frappe
Frappe
- A team building an internal business application that needs permissions, audit trail and an API on day one rather than in month threenot Cortex
- An ERPNext user who wants managed hosting, automatic updates and offsite backups without hiring a systems administratornot Cortex
- An Indian or emerging-market business that wants to pay for application hosting in local currency at local price pointsnot Cortex
- A consultancy shipping custom vertical apps to clients on a shared framework with per-client site isolationnot Cortex
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.
Frappe
- The framework is strongly opinionated: its own ORM, templating and job queue mean general Python and Django experience transfers only partly, and onboarding a new developer takes weeks rather than days.
- The developer pool is small and heavily concentrated in India, so hiring Frappe experience elsewhere is slow and expensive relative to mainstream stacks.
- Documentation is uneven in depth and lags behind releases in places, so real answers often come from reading the source or the community forum.
- Major version upgrades of the framework have historically broken custom apps that reach past the DocType layer, so bespoke code carries a recurring maintenance cost at each upgrade.
- Frappe Cloud recommends against its cheapest Hetzner-backed option for mission-critical production, so the headline $5 entry price is not the price of a production-grade deployment.

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.
Frappe: Is Frappe the same as ERPNext?
No. Frappe is the framework; ERPNext is the ERP application written on it. You can run Frappe without ERPNext to build your own applications.
Cortex: Is pricing published?
No. Cortex requires a sales conversation and prepares a custom proposal.
Frappe: What licence is the framework under?
MIT, which is permissive and imposes no obligation to publish your changes, unlike the AGPL used by several open source ERP rivals.
Cortex: Can it self-host?
It is offered as a hosted product; on-premise arrangements are handled through sales rather than published.
Frappe: Can I pay in rupees?
Yes. Frappe Cloud publishes the same plans in Indian rupees, ₹410 a month for sites and ₹3,600 for servers, rather than converting a dollar price at checkout.
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.
Frappe: Do I have to use Frappe Cloud?
No, self-hosting with bench or Docker is fully supported and free. Frappe Cloud is a convenience purchase, and it funds the open source work.
