Simple, transparent pricing to meet every educator's needs

Yes — and free runs your whole class, not a stripped-back sample of it. Educator Basic includes the entire open-content catalog, 10,000+ auto-graded practice problems, Pathfinder, one-click differentiation, and auto-grading with class analytics — with no section or learner caps, no credit card and no expiry. Most educators never need more than this — raising the bar for free CS platform offerings. See where the paid plans add value on the Pricing page.

Three tiers in each segment. In K-12: Educator Basic (free), Educator Premium (priced per section, per year) and District License. In higher education: Instructor Basic (free), Department Premium (priced per learner, per term) and Campus License. Every plan is available at every size. Starting prices for each are on the Pricing page; your own figure comes from the quote you generate.

No. Starting prices are published, and you generate your own quote inside Alps — enter your sections or learners, turn the quote into an invoice yourself, and pay by ACH, check or card. Your features unlock on payment, with no form to fill in and no call to book. Sales only gets involved for larger deployments, where implementation and contract terms genuinely vary.

You pay whichever is greater: the total for your sections or learners, or the plan minimum. Adding a section or a learner always costs less than the one before it, and never triggers a jump. The minimum for each plan, and how much it covers, is shown on the Pricing page.

In K-12, usually nothing changes. We price by class-size range rather than per learner, so a few students joining or leaving normally leaves your price exactly where it was. If a class grows enough to move into the next range, re-generate your quote with the new numbers and pay the difference — it is typically minor.

If you add a whole new section, re-quote the entire subscription rather than just the new one: running more sections lowers the cost of each, so the better rate applies across all of them and you pay only the difference.

In higher education, enrollment is counted once for the term. Either way, we never re-price a term you have already paid for, and we don't recalculate your bill at the end of the year.

International schools are billed in USD. Your exact rate is confirmed in the quote you generate, before you pay anything.

No. All prices exclude sales tax, VAT and GST. Most public schools and districts are exempt — upload your exemption certificate in your billing settings.

Open content is free on every plan, forever — that covers most of what is taught in introductory computer science, plus several titles created by 2Sigma School, including Generative AI: Programming with LLMs, Logic Gym and Nifty Assignments. Publisher titles are licensed separately, per learner, at each publisher's own list price. In K-12, educators buy them inside Alps for the students in their sections, on the same invoice as their subscription. In higher education, students can pay directly at checkout, or your bookstore can buy in bulk and receive redemption codes to distribute — contact sales@alps.2sigma.us.

You can price and buy a District or Campus License yourself, without talking to anyone. For larger deployments — or where you need implementation support, professional development or custom contract terms — schedule a demo and we will quote directly.

In K-12, no — learners never pay. Access is provided through their educator or institution, and they join with a link, an LMS launch or SSO. In higher education a department license also means students pay nothing; if a department prefers, students can instead buy access or a licensed title directly at checkout.
