01
Write code. See exactly what passed.
Students solve in the browser, hit run, and get per-test results in seconds — each run isolated in its own sandboxed container. No installs, no local setup.
For schools & CS teachers
Teach programming students actually learn from.
Real, auto-graded coding challenges in the browser. Every run sandboxed, every result instant. Build a whole course by hand — or let the assistant do it.
The problem
Students aren't getting the fundamentals.
And the tools meant to teach them haven't kept up. So we built the one we wished we had.
The platform
Everything a CS class needs,
nothing it doesn't.
02
The assistant builds your course.
“Make a recursion course with five problems, increasing difficulty.” The built-in AI assistant writes the problems, tests, files, and pages — on your own API key, every action logged. Students get their own AI tutor that hints and explains, but never hands over the answer.
03
See how each student got there.
Every submission, with per-test results and an activity calendar — right down to the attempt where it finally clicked. Mistakes become teachable moments, not a red X.
04
Authoring that stays out of your way.
A problem is a statement, starter code, and tests — static input/output pairs or a reference solution with a random input generator. Attach any file. Python and C#, out of the box.
Secure by default
Every run gets a throwaway container with no network and hard memory and CPU limits. Untrusted student code never touches your machine.
Groups are your classes
Assign a course to a group with an optional due date. Everyone gets access — and an email — automatically.
Solve in VS Code too
A first-class extension for students who'd rather stay in their own editor. Same problems, same instant feedback.
Self-hosted
Run it on your own infrastructure. No third party sees your students, their code, or their grades.
Our philosophy
Simple tools,
done right.
No bloat, no lock-in, nothing you have to Google to understand. The whole platform is built to be read, not just used — and that's exactly why it stays out of the way of teaching.

Who we are
Two students, tired of bad tools.
We're building AlgoStudio because we've lived the problem from both sides of the classroom.
Harold
Co-founder & Student
Business student already in active conversations with some of the bigger schools in the Netherlands. Ready to talk.
Kieran
Co-founder, Student & Software Engineer @ ASML
Manages interns who struggle with the same gaps in algorithms and good code practice — exactly the problem AlgoStudio fixes.
For schools and teachers
Bring AlgoStudio to your classroom.
We're partnering with schools to test it with real classes. If you teach CS and want a say in what this becomes, let's talk — we can move quickly.
