The whole simulator. You get every board and every part, the breadboard, the wires, the Serial Monitor and the compiler. Run your circuits as often as you like. There is no time limit and nothing to count down. You don’t even need an account. You can also download pictures of your circuit (PNG and SVG). On Free they have a small "made with mokxi.com" badge in the corner, and a paid plan takes it off.

No. The editor, the templates, the gallery, the compiler and Run all work without signing in. Your browser keeps your work as you go. An account saves your projects online, so they follow you to any computer. It also gives you a link to share.

More room to build and share. You can keep as many private projects as you want, instead of 5 private or link-only ones (public projects are unlimited on every plan). You can go back up to 200 saves on each project, instead of 5, and name, star and compare them side by side. Your WiFi boards can reach the real internet, and you can record videos of your circuit up to 5 minutes long with no badge. There is no limit on how many people can work on a project together, instead of you and one friend. You can make as many classes as you like, with up to 10 students in all. Your pictures and website projects have no badge. And our team answers you first. Every part of the simulator is on Free too, so Pro never locks any of it away.

Teacher. It is $129 a year, or $14 a month, and forty students are included. That is you plus forty students, in as many classes as you like, for one flat price. You get everything in Pro. You and your whole class can build on one project at the same time. While your students are in your classes, they get Pro features too, with no badge on their pictures or website projects. The forty are counted across all your classes, and a student in two of them counts once. We love teachers. If you get stuck, a real person will help. For more than forty students, or more teachers, choose Schools & universities. We price it for you.

Yes. Make a free account, open the class page, and press Start 30-day free trial. For thirty days, one class of up to forty students gets the Teacher plan’s class tools. Your students get Pro features while they are in it. You don’t need a card, and each teacher account gets one trial. When it ends, nothing is deleted. You can still read the class list and the work your students handed in. The class page shows how to keep going.

Yes. Each account can try everything in Pro free for seven days, with no card. We offer it when you reach a limit on the Free plan. If you are signed in on Free, you can also start it from this page. When the trial ends, you are back on Free and nothing is deleted. Projects over the limit stay open to read.

That is Schools & universities. It is for more than forty students, more teachers, or a whole school, district or university, and we price it for you. Press Talk to us and a person will walk you through it. Or enter your number of students in the calculator on the classroom page to get a written quote in minutes. The seats go on the account of the teacher who asks, so each teacher with classes asks for their own. The quote comes as a PDF with lower prices for more students. Your school can pay by card, or by purchase order with 30 days to pay. Every student gets everything in Teacher, and the whole class can build together with no limit on people. We also sign your data privacy agreement and help set up your classes.

A seat is one student. Your own place in the class is free. So a class of thirty students is thirty seats, and thirty-one people in all. The Teacher plan includes forty seats for one flat price. When a student leaves, remove them, and the seat is ready for the next one.

The Mokxi API lets your own code run circuits on our servers. The simulated time counts toward a monthly amount: 100 minutes a month on Free, and 2,000 on Pro and Student. Teacher and Classroom get 2,000 too, shared by the teacher and the students in their paid classes. Schools and universities can ask us for more. The count starts over on the first of each month. A run that starts under the limit always finishes, and you are never charged for going over. None of this touches the editor. Circuits you run in your browser are unlimited on every plan. The command line tool, the VS Code extension and GitHub sync are on every plan too.

Yes, any time, from your account page. You don’t have to write to anyone. Press Manage billing to open Stripe’s page. There you can change your card, get invoices, change plans or cancel. If you cancel, your plan lasts until the end of the time you already paid for. Your account page shows that date. On a school’s plan, you change the number of students on the account page, and Stripe works out the cost for the rest of the period.
