Trinket Is Still Free: Hosted by Strive for Every Classroom

Good news for teachers: Trinket is still free and available to every classroom. When Trinket.io wound down, its founders Brian and Elliott generously released the software as open source so the community could carry it forward. Strive is now hosting it, free and open, for every teacher and student who relies on it. You can continue using Trinket at trinket.strivemath.org.

Trinket Lives On at trinket.strivemath.org

Trinket has helped teachers and students around the world fall in love with coding right in the browser. Strive didn't want a single classroom to lose that, so we took the open-source Trinket code and now run it ourselves at no cost to the community.

Run Python, HTML, CSS, JavaScript, and p5.js in your browser, share it with your students, and know it's here to stay. No paywalls, no cost, just the trusted Trinket experience you already know.

Why Strive Is Hosting Trinket for Free

Made for educators, kept alive by educators. Trinket is built for the classroom — it removes every barrier between a student and their first line of code. When the original hosted service closed, we saw an opportunity to do something useful for the teaching community.

Strive runs two coding programmes for students — Python fundamentals and AI-First Software Development for students who've completed the fundamentals. We use browser-based coding tools every day, and we know how much they matter in a classroom context. Keeping Trinket available was the obvious thing to do.

Frequently Asked Questions About the Free Trinket Platform

What is Trinket?

Trinket is a browser-based coding platform built for the classroom. It lets anyone write and run Python, HTML, CSS, JavaScript, and p5.js directly in the browser with no logins, plugins, or installs required. Teachers have long used Trinket to build interactive lessons and courses, and learners use it to experiment, save, and share their projects.

What Does It Mean That Trinket Is Open Source?

Trinket's founders released the platform as open source, which means anyone can read the code, contribute to it, or run their own copy. The version at trinket.strivemath.org runs on that open-source project. Because it's open and community-hosted, there are no paid plans or trials — every feature is free for everyone.

Who Hosts the Free Open-Source Version of Trinket?

Strive Math, a Singapore-based education technology company, started hosting the free version of Trinket in late May 2026. When the original hosted service wound down, Strive took over running the open-source version at trinket.strivemath.org so classrooms wouldn't lose a tool they rely on.

Note: this is an independent, community-hosted edition and is not the commercial trinket.io service.

Is the Strive-Hosted Trinket Really Free?

Yes. Trinket at trinket.strivemath.org is completely free with no paywalls, no paid plans, and no trial periods. Every feature is available to every user.

What Programming Languages Does Trinket Support?

Trinket supports Python, HTML, CSS, JavaScript, and p5.js. All of these run directly in the browser with no installation required.
