Fly.io has partnered with Tigris to provide an S3-compatible object storage solution for developers, making it easier and faster to handle file uploads in full-stack applications. The integration allows users to use the AWS libraries to put and delete objects into Tigris using the same calls that they use for S3. Fly.io has also wrapped everything under one bill, allowing users to pay a single monthly fee for their computer, block storage, databases, networking, and object storage needs.
