Built by students, for students

The coding platform
students actually want to use

We notice a trend, most students don't understand basic algorithms anymore. When they try to, they're met with ancient tools for learning them and teachers who can't begin to understand where their students are at. It is our mission to fix these problems.

The platform

Everything a CS class needs,
nothing it doesn't

We designed AlgoStudio around how students actually work, not how textbooks say they should.

01

Clean problems, instant feedback

Students see the problem, write their solution, and run it all on one screen. No switching tabs, no hunting for the submit button. The editor runs code directly against test cases and shows results straight away so students can iterate fast.

02

See exactly where things went wrong

Every submission is tracked. Teachers can see how long they spent, compare diffs between attempts, and understand what actually changed between a failing and passing solution. Mistakes become learning moments instead of just a red X.

03

Simple for teachers to set up

Creating a problem is as easy as writing a markdown file and adding test cases. No complicated admin interface. You can attach files directly, something we have seen no other tool do. This allows for unmatched flexibility and the possibility to create problems where you can really challenge your students.

Our philosophy

Simple tools
done right

We're not big on complexity for its own sake. AlgoStudio runs on plain HTML, CSS and vanilla JavaScript. No framework, no build step, nothing you have to Google to understand.

Here's our entire keyboard shortcut system. Every Ctrl+K, every Alt+Enter, handled in one small file. We think that says something about how we build.

Who we are

Two students who got tired
of bad tools

Harold studies business and already has meetings lined up with schools across the Netherlands. Kieran works as a software engineer at ASML and manages interns there, which is exactly where he sees this problem play out every day.

For schools and teachers

Help us make this better

We're actively looking for schools to test AlgoStudio with real classes and give us honest feedback. This is not about shipping something and walking away. Harold is already talking to schools in the Netherlands and can get things moving quickly. If you teach CS and want to be part of shaping what this becomes, reach out.
