Trinket.io is shutting down in August 2026, and they made their code open source in March 2026. No one was hosting the open source version since the server costs are so high. So using our YC Bookface discounts, we decided to host it for free for the entire education community.

So trinket now lives on a trinket.strivemath.org and it's free for everyone. It's the best alternative to trinket.io.

I saw so many other companies try to push their own paid coding editors, most of which are 2x to 10x more expensive than trinket. So we decided that a free platform, hosted by an education company that follows all data privacy rules is better for the education industry.

I really appreciate it when services open source their software when they shut down. There's so many amazing sites, software, games, or other neat solitons that are gone forever because there's no way to access it or replicate it.
