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. A free account saves as many projects as you like. They are public: anyone can find them, open them and remix them. Projects you already made private or link-only stay that way. 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.

Everything in Free, plus every tool. Your projects can be private or shared by link only. Mokxi for VS Code works with your account. 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.

Pro for work is $20 a seat a month, from 2 seats. Every seat gets everything in Pro, plus 5,000 CI minutes a month for the Mokxi GitHub Action and the command line tool in CI. One person pays, invites the team by email from the account page, and gets one bill with invoices and receipts. Your company can add its tax id at checkout.

Yes, since October 2026. Mokxi for VS Code is part of Pro, and CI runs (the GitHub Action, and the command line tool in a CI job) are part of Pro for work. Running a sketch on your own computer with mokxi run stays free, with no account. If you used VS Code or CI in the 60 days before the change, you keep it until December 11, 2026, and the tool tells you so.

Teacher. It is $129 a year, or $14 a month, and 40 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.
