Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

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.

Keygen

  • Specific Active Licensed User (ALU) pricing not listed; requires interactive pricing calculator
  • Whitelabel API add-on costs $995/year per domain

Yes, the Dev tier is free and supports up to 100 Active Licensed Users with 10 product releases and core licensing API access.

Source
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.

Keygen: How is Keygen pricing calculated?

Keygen uses scalable, flat monthly or yearly fees based on your licensing volume (Active Licensed Users). No revenue share or transaction fees are charged.

Source
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.

Keygen: Does Keygen charge for additional features like SSO?

SAML/SSO is included in Enterprise tiers. Whitelabel API support costs $995/year per domain. Premium Support SLA is $995/month for Enterprise.

Source
