The short version

  • Only Khan Academy has a free tier, so it costs nothing to try first.
  • Each has a real cost: Khan Academy the Internet Archive's capture of Khan Academy's homepage on 1 January 2021 stated it is a 501(c)(3) nonprofit and that its full library of practice and lessons 'is all free for learners and teachers', funded by donations rather than subscriptions.; Lightspeed Systems no module has published pricing, so districts cannot benchmark a quote without running a formal procurement, and the eventual figure depends heavily on which co-operative contract they buy through.
  • They diverge on capability: Khan Academy covers Video lessons, Lightspeed Systems covers Filter.
  • 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.

Khan Academy

  • Free self paced learning across maths, science and humanitiesnot Lightspeed Systems
  • Assigning practice and tracking student progress in a classroomnot Lightspeed Systems

Lightspeed Systems

  • A district with 15,000 take-home Chromebooks that needs filtering to follow the device onto home and public networksnot Khan Academy
  • A technology director being asked to justify the edtech budget, who can use app usage data to cancel licences nobody opensnot Khan Academy
  • A school board that has agreed to safety monitoring but has no staff able to respond to alerts at night, and so buys the human review servicenot Khan Academy
  • A one-to-one iPad rollout wanting device enrolment, filtering and teacher screen control from one vendornot Khan Academy

Where each one falls short

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

Khan Academy

  • The Internet Archive's capture of Khan Academy's homepage on 1 January 2021 stated it is a 501(c)(3) nonprofit and that its full library of practice and lessons 'is all free for learners and teachers', funded by donations rather than subscriptions.

Lightspeed Systems

  • No module has published pricing, so districts cannot benchmark a quote without running a formal procurement, and the eventual figure depends heavily on which co-operative contract they buy through.
  • Alert detection and the 24/7 human review that makes it actionable are priced separately, so a district that budgets for Alert alone ends up owning the overnight triage burden itself.
  • The agent model means coverage stops at the managed device, and students moving to a personal phone on mobile data are outside filtering and monitoring entirely, which undercuts the compliance claim in the exact scenario administrators worry about.
  • Teacher screen monitoring is frequently deployed without training, and lessons stall while staff learn the interface, so the first term of a Classroom rollout often produces complaints rather than the intended benefit.
  • Buying eight modules from one vendor makes renewal a single high-value negotiation with no partial leverage, and districts locked into a multi-year co-operative contract cannot easily drop a module that underperforms.

Answered from the vendors’ own pages

Khan Academy: Is Khan Academy free?

Yes. Khan Academy is a 501(c)(3) nonprofit and states that it is a free tool for students, teachers and parents alike, with over 840 free courses and teacher tools provided at no cost. It relies on donor support rather than fees.

Source
Lightspeed Systems: How much does Lightspeed Filter cost per student?

Lightspeed does not publish rates. Pricing is quoted per student device per year and varies with district size, module mix and which purchasing co-operative contract you buy through.

Khan Academy: Who is Khan Academy for?

Khan Academy serves students, teachers and parents, covering core academic subjects from K-12 through early college. The platform is available in more than 190 countries and over 55 languages.

Source
Lightspeed Systems: Is 24/7 human alert review included with Alert?

No. Alert provides the detection; the staffed round-the-clock review service is an additional purchase, and it is usually what districts actually need.

Khan Academy: How is Khan Academy funded if it is free?

As a 501(c)(3) nonprofit, Khan Academy is funded by donations rather than subscriptions. Its about page states that donor support is what keeps the classroom tools free.

Source
Lightspeed Systems: Does filtering work when students are at home?

Yes, the agent runs on the device rather than the network, so policy follows the Chromebook or laptop off site.

Lightspeed Systems: What does Insight actually do for the budget?

It reports which licensed apps are opened and by whom, which districts use to cancel subscriptions with low usage. It also flags whether an app meets named privacy and accessibility standards.
