MultipleUpload vs Uppy
Both are serious, backend-agnostic JavaScript uploaders with resumability, cloud sources and framework support. This is the fairest fight in the category — the differences are architecture and economics, not capability gaps.
Uppy is open source (MIT), modular, and backed by Transloadit; you compose @uppy/core with the plugins you need, and its hosted or self-hosted Companion handles remote sources. It is an excellent default.
MultipleUpload is one commercial bundle where the same territory — and some less common ground — is built in and switched on by options. No plugin graph, no version matrix, one script tag (or one npm package).
Pick Uppy if MIT licensing or the plugin ecosystem matters most. Pick MultipleUpload if you want the assembled product with a licence and support behind it.
Where both are strong
- • tus 1.0 resumable uploads and direct-to-S3 multipart
- • Survive-a-reload persistence (Golden Retriever /
persistBlobs) - • Remote sources: Drive, Dropbox, OneDrive — both via a Companion-style broker you can self-host
- • Webcam capture, i18n, drag-and-drop, previews
- • First-party framework support (Uppy: components; MultipleUpload:
useUploader()for React/Vue, Svelte action, Angular service)
Where they genuinely differ
| Dimension | Uppy | MultipleUpload |
|---|---|---|
| Architecture | Modular core + official plugins you select and version together. | Single dependency-free bundle; features are options. |
| Licence | MIT. | Commercial; free on localhost for evaluation. |
| Azure / GCS direct | S3 is first-class; other clouds via your endpoint. | Built-in Azure Blob and GCS resumable strategies alongside S3. |
| Resume integrity | Protocol-level (tus HEAD). | Protocol-level plus a chunk-status probe for plain chunked uploads, so client state is verified against the server. |
| Network adaptation | Retries with backoff. | AIMD adaptive concurrency, circuit breaker, bandwidth cap, stall watchdog. |
| Beyond transfer | Image editor plugin; Transloadit integration for processing. | Built-in editor (smart-crop, redact, watermark, HEIC, AVIF), AES-GCM encryption-at-rest, cross-tab dedupe, magic-byte MIME checks. |
Trying it side by side
Both speak tus, so you can point MultipleUpload at the tus server you already run (strategy: 'tus') and compare behaviour on your own network before deciding anything. tus demo
