What Is Toph
Toph (টাফ) is Bangladesh’s leading competitive programming platform for hosting programming contests at scale. It supports both online and on-site contests and is designed to accommodate contests of any scale.
How it works
- Participants submit solutions through Toph’s web interface.
- Submissions are executed in a secure sandbox and automatically evaluated against each problem’s specifications.
- Toph’s infrastructure handles scaling and evaluation; organizers do not need to run their own judging servers.
Contest modes
- Online contests: Participants join from anywhere in the world via the Toph website.
- On-site contests: Participants use devices you provide at the contest venue; access can be restricted to the local network or specific devices.
