ElasticUpload®
Files over 100GB upload reliably, and when the network drops, the upload picks up where it left off — not from zero. Built on the tus standard with reactive, async processing for minimal resource use and maximum throughput.
Supported clouds
When the network drops, you don't start over.
Uploading large files reliably is harder than it looks. Networks drop. Devices vary. Clouds go multi. Starting an upload over from scratch is a cost — for users and for operators.
ElasticUpload sits on top of tus, the global standard upload protocol. Files past 100GB go up reliably, and when the network blips and recovers, the transfer continues from the last successful point. Reactive and async programming keep resource use tight while pushing throughput up.
One protocol talks to S3-compatible storage and every major cloud — infrastructure stays simple, and moving between clouds becomes a non-event.
Big files and multi-cloud, in one place
tus standard, reactive and async processing, and storage compatibility that travels.
100GB+ resumable
Files over 100GB upload without interruption. When the network drops and recovers, the transfer resumes from the last successful point — not from zero.
Built on the tus protocol
We sit on top of tus, the standardized upload protocol validated by major tech companies. Compatible with any standard tus client or server.
Reactive & async
Reactive and async programming keep resource use minimal while pushing throughput up. It stays light even with many concurrent uploads in flight.
S3-compatible storage
Connects directly to AWS S3 and self-hosted S3-compatible stores like MinIO. Swap the storage and your code stays the same.
Multi-cloud
Supports AWS, Naver Cloud, KT Cloud, Kakao Cloud, Digital Ocean, and Supabase. Microsoft Azure and Google Cloud Platform are on the roadmap.
Frontend frameworks
Drop-in support for React, Vue, Svelte, and Angular. You don't need to know the internals of tus to wire up an upload.
