Where each one falls short

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

ClassLink

  • It is a single point of failure by design; a ClassLink outage locks pupils out of every application at once, which is a worse day than any individual product failing.
  • Pricing is entirely quote-based and per student, so a district cannot budget for it without a sales cycle, and comparisons against Clever come down to negotiated rates rather than list prices.
  • Rostering accuracy is only as good as the SIS data behind it, and districts with messy enrolment or course records find ClassLink faithfully propagates that mess to every downstream vendor.
  • Applications that do not support SAML or OIDC are handled by a browser extension that replays stored credentials, which works but breaks whenever the vendor changes its login page and is a weaker security posture than real federation.
  • Analytics measures logins and session activity, not learning or engagement, so a product that pupils open and abandon still looks used; districts that treat the numbers as proof of value draw the wrong conclusion.

Duolingo

  • Free tier includes ads and energy-based hearts system limiting daily practice without paying
  • Gamification focus may appeal to casual learners but lacks depth for serious language study beyond conversational basics
  • Limited to short, bite-sized lessons without extensive grammar explanations or cultural context

Answered from the vendors’ own pages

ClassLink: How is ClassLink different from Clever?

Both do SSO and OneRoster provisioning to schools. ClassLink leans harder on usage analytics and on access to on-premise network file shares; Clever leans on its application marketplace. Vendor support is broadly comparable.

Duolingo: What is Duolingo's pricing model?

Duolingo offers free tier with ads and limited features, Super Duolingo at $12.99/month (ad-free, unlimited hearts, extra practice), Super Family at ~$119.99/year for up to 6 users, and Duolingo Max with AI features like Video Call and Roleplay.

Source
ClassLink: Does it replace Google or Microsoft accounts?

No. It sits over them. Pupils still have an underlying Google Workspace or Entra ID identity and ClassLink federates to it.

Duolingo: Is Duolingo effective for language learning?

Duolingo has 135+ million monthly active users as of Q3 2025, making it the world's most widely used language-learning app. Its gamified approach and free tier have driven massive adoption.

Source
ClassLink: Is pricing published?

No. It is quoted per student and varies with district size and which of LaunchPad, Roster Server and Analytics you licence.

Duolingo: What AI features does Duolingo Max include?

Duolingo Max includes Video Call for conversation practice with AI character Lily and Roleplay for scenario-based speaking practice. As of January 2026, Explain My Answer became free for all users.

Source
ClassLink: Does it work outside the United States?

Yes, but the OneRoster ecosystem and the SIS integrations are strongest for US K-12; international deployments get less of the prebuilt vendor coverage.

Duolingo: Does Duolingo work offline?

Duolingo is primarily online, though it may offer limited offline lesson downloads on some platforms. Full features require internet connection.

Source
ClassLink: Can Analytics prove a product is worth renewing?

It proves whether people log in. It cannot tell you whether the time spent was useful, so treat low usage as a firm signal and high usage as a weak one.
