Self-hosted alternatives to WeTransfer
2 GB cap, files expire in a week, and recipients get ads on the download page.
Below are 10 open-source projects that cover the same ground, each scored 0–100 on how actively it is actually maintained — commit volume, release cadence and recent trend. 4 of the 10 are currently rated healthy or better. Ordering reflects that score, not sponsorship.

How these were picked
Every project listed here is open source and can run entirely on hardware you control. We start from the categories that match WeTransfer's job — File Transfer - Single-click & Drag-n-drop Upload — then rank by health score so that a popular-but-abandoned project never appears above a smaller one that is actively shipping. The scoring method is documented in full.
The scores are recomputed from repository data on every rebuild, so this page reflects the state of these projects as of 1 Oct 2026 — not the day it was written.
Yopass
Secure sharing of secrets, passwords and files.
Best fit: It suits administrators and teams who need a secure, internal mechanism to transmit credentials or configuration files without relying on third-party cloud services.
Worth knowing: You will need to manage your own expiration policies and network access controls, as exposed instances can become vectors for data exfiltration if left unsecured.
ProjectSend
Upload files and assign them to specific clients you create. Give access to those files to your clients.
Best fit: Freelancers and small agencies that need a straightforward, branded portal to share deliverables directly with individual clients without relying on third-party cloud storage.
Worth knowing: The codebase has a moderate maintenance tempo, meaning you should evaluate whether the feature set and security update cadence align with your long-term requirements.
OnionShare
Securely and anonymously share a file of any size.
Best fit: It is well-suited for individuals or teams who need to send large files without relying on third-party cloud storage providers or revealing their network location.
Worth knowing: You must account for the dependency on the Tor network for anonymity, which can introduce latency and transfer bottlenecks depending on network conditions.
Slink
Image sharing platform designed to give users complete control over their media sharing experience.
Best fit: Self-hosters who want a dedicated, private endpoint for sharing screenshots or image files without relying on external services.
Worth knowing: The image-sharing category has many mature alternatives, meaning you should check whether its specific feature set meets your workflow before migrating.
Zipline
A lightweight, fast and reliable file sharing server that is commonly used with ShareX, offering a react-based Web UI and fast API.
Best fit: Ideal if you want a dedicated, lightweight endpoint for rapidly uploading and sharing files via drag-and-drop or automated client tools.
Worth knowing: Maintenance health is steady rather than rapid, and as a niche file sharing tool, it may lack the extensive ecosystem and collaboration features found in larger storage platforms.
