Trinket, a browser-based coding platform designed for classrooms that allows users to directly execute Python, HTML, and other languages in a browser, was scheduled to shut down but has been made open source and free to continue.

Trinket is an online code editor service aimed at people learning programming in classrooms, and its distinguishing feature is that it allows users to directly execute source code in languages such as Python, Java, and HTML within a browser. It had been operating for a long time as

Trinket.io , but the service was suddenly shut down, and it has now been relaunched as a free community version after being open source.

Founded in 2013 by Elliot Hauser and Brian Marks as a company developing tools for educators, Trinket.io operates under the philosophy that 'anyone can learn programming without setting up an environment, as long as they have a browser.' In May 2014, they officially released 'Python Trinket.' At the time, installing software was essential for learning programming, so Trinket's groundbreaking widget, which allowed users to 'write code in a browser, execute it on the spot, share it, and embed it in blogs, etc.,' became a huge hit on Reddit and Hacker News. Organizations such as '

Code Club ' and the ' Raspberry Pi Foundation ' successively adopted Trinket as their official platform for running educational materials. Furthermore, during the global lockdowns caused by the COVID-19 pandemic, it was used explosively as a learning management and instruction tool for children studying at home and teachers conducting remote classes.

However, in March 2026, 12 years after its launch, the development team suddenly announced that all official services would be terminated on August 31, 2026.

While the specific reasons for the service termination have not been stated, it is believed that the main reasons were limitations in the business model, such as 'enormous server costs' and 'increasing competition with other platforms.' It is also speculated that, having been established for 12 years, the system's foundation had become outdated, and the management decided to terminate the service rather than invest further costs in a large-scale system overhaul.

Trinket was destined to disappear when its service ended, but a turning point came when the developers released the system's code as open source to prevent the loss of its existing assets. Strive Math , a Singapore-based educational platform operator, saw competitors seize the opportunity presented by Trinket's closure and launch marketing campaigns to encourage users to switch to their own code editors. This sparked a sense of crisis regarding the exploitation of education by commercialism, and after successfully raising server costs by leveraging the community benefits of Y Combinator , to which Strive Math belongs, took on the hosting and operation of a free community version of Trinket based on the open-source version.

With the change in management, users who previously used Trinket.io will no longer be able to continue using it as is. However, before the service ends, you can download your data by clicking the 'Download All Trinkets' button on the Trinket.io Settings/Data screen and import it into the community version of Trinket to transfer your existing assets.
