What is Trinket?

Trinket is a browser-based coding platform made for the classroom. It lets anyone write and run Python, HTML, and more right in the browser — no logins, plugins, or installs required — and makes it easy to share or embed the result anywhere. Teachers have long used Trinket to build interactive lessons and courses, and learners use it to experiment, save, and share their projects.

Open source

The Trinket platform was released as open source, which means anyone can read the code, contribute, or run their own copy. This site 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. You can find and contribute to the source on GitHub.

Who hosts this site?

This edition is hosted by Strive Math, a Singapore-based education technology company. When Trinket's original hosted service was winding down, Strive took over running the open source version at trinket.strivemath.org so classrooms wouldn't lose a tool they rely on.

Strive was founded in 2020 with a simple idea: in the real world, math and science are done with computers and code, yet students still work everything out by hand. Strive turns abstract concepts into coding projects to make learning more relevant, engaging, and joyful — and builds and shares free tools for teachers everywhere. Hosting this community edition of Trinket is part of that mission.
