Cloudflare R2
S3-compatible object storage. Zero egress fees.
Plain language
What is it?
A cloud file storage service (like Amazon S3) that charges zero fees for downloading files — which makes it much cheaper for apps with lots of content.
Why use it at a hackathon?
When your app serves many files (documents, images, reports) to many users, S3 egress fees add up fast. R2 eliminates that cost entirely.
Common use
Document archives for legal or health apps, civic open data file hosting, educational content libraries, food safety report storage.
