The key to open education
Trinket lets students and educators write and run code directly in the browser — Python, HTML, Java, R and more. No installs, no friction, just code.
Everything you need to teach with code
A complete coding environment, reimagined for the classroom.
Browser-based editor
A full VS Code-grade editor (Monaco) in the browser. Nothing to install — students just start typing.
Run code instantly
Execute Python, HTML/CSS/JS and more right inline. Output appears next to the code, no setup required.
Share & embed
Every trinket gets a short link and an embed code. Drop interactive examples into any webpage.
Build courses
Compose lessons with embedded, runnable trinkets to create interactive coding curricula.
Fork & remix
Start from any public trinket. Fork it into your account and make it your own in one click.
Modern stack
Next.js 16, tRPC, Better Auth, Upstash QStash and Vercel Blob — fast, typed, and serverless-ready.
Many languages, one editor
Pick a language and start a trinket in seconds.
