Open-source Sendspace alternatives

MicroBin is a small, self-contained and self-hosted paste bin web application written in Rust. It is quick to set up and needs only a few megabytes of memory and disk storage, and it ships as a single executable file.

An upload can be a pasted text, one or more attached files, or a URL redirection. Uploads can be private or public, editable or read-only, and set to expire automatically or never. Other features include server-side and client-side end-to-end encryption, QR code support, raw text serving, animal names as upload identifiers, automatic dark mode, and SQLite or JSON storage.

People use it to send long texts or large files, share sensitive documents, shorten URLs and serve configuration files or images through its raw endpoint. It can be installed through a Docker setup script or from Cargo, and is licensed under BSD-3-Clause. The project website offers screenshots, documentation and a roadmap.

Zipline is an open-source file upload server that you run yourself. It began as a destination for ShareX screenshot and file uploads and has grown into a general personal or team file host with a web interface, an API, and a gallery view for uploaded media. It is released under the MIT license.

Uploads can be organized into folders and tags, shortened into compact URLs, and shared with embeds that preview cleanly in chat apps. Access can be tightened with password-protected links, invite-only registration, per-user quotas, OAuth2 sign-in, two-factor authentication, and passkeys. Image compression, video thumbnails, and partial uploads help with larger files, and webhooks can notify Discord or any HTTP endpoint.

Deployment is Docker-based: you mount volumes for uploads, public assets, and custom themes, and set a secret value before the first start. The host CPU must support AVX instructions, because the project does not publish builds for older processors. Zipline suits individuals, communities, and small teams who want a private alternative to public image and file hosts.

Gokapi is a self-hosted tool for sharing files, presented as an alternative to Firefox Send. It is written in Go and runs on Linux, macOS and Windows or in a Docker container. Unlike many upload services, it does not allow public uploads: only registered users can add files, which keeps the instance under the owner's control.

Shares can expire automatically after a set number of downloads or days. A file request feature gives outside parties a link to upload files that only the link's creator can see. Other features include user management with roles, file deduplication so identical files use no extra space, built-in encryption including end-to-end encrypted uploads, a REST API for automation and a UI that can be customized with CSS and JavaScript.

Storage can be local or AWS S3, including S3-compatible services such as Backblaze B2. OpenID Connect support allows sign-in through providers like Authelia or Keycloak. The minimum requirements are modest, around one CPU core and a few hundred megabytes of memory, and a setup wizard runs on first launch. Gokapi is licensed under AGPL-3.0.

Chibisafe is a file uploader service written in TypeScript. You send it files, photos or documents and it gives back a shareable link. It is described as easy to use and deploy, and it can run in public mode, user accounts mode or invite-only mode, depending on how open you want your instance to be.

Large files are uploaded in chunks to reduce failures from network problems, and users can create API keys to use the service programmatically. An admin dashboard exposes most instance settings, including the name, rate limit, maximum file size and accepted extensions, so you rarely need to edit configuration files by hand.

Version 6 adds S3 storage support, a masonry layout for browsing media, albums and folders with direct links, snippets, file management and tagging, user management with quotas and a built-in URL shortener. ShareX support, an iOS shortcut and a browser extension help with uploading from desktops, phones and websites. It is open source under the MIT license, runs without ads, and logs IP addresses of requests.

Plik is a temporary file upload system written in Go that works like WeTransfer but runs on your own infrastructure. It has a modern Vue 3 web interface with 12 languages and light, dark, and custom themes, along with a command-line client. The input lists its license only as other.

It supports several storage backends: local disk, S3, OpenStack Swift, and Google Cloud Storage. Metadata can be stored in SQLite, PostgreSQL, or MySQL, and multiple authentication providers are available. Topics also mention end-to-end encryption, Docker deployment, and an MCP interface. Uploads are temporary, expiring after a set time.

The project provides documentation, a live demo, and Telegram channels for discussion and release announcements. Plik suits teams and homelab users who want a simple way to send large files to others without accounts on third-party services.

Sharry is a self-hosted file sharing web application. The basic idea is simple: you upload files and receive a URL that you can pass on to others, instead of sending large attachments or using a third-party sharing service.

Authenticated users can upload files with an optional password and a time period that controls how long the files remain downloadable, and the resulting public link can be shared by email. In the other direction, each registered user can maintain alias pages behind hard-to-guess URLs, which let anyone upload files to that user with a description, optionally notifying them by email. Alias pages can be disabled or deleted at any time. The upload implementation follows the tus protocol.

Sharry is built with Scala and Elm and licensed under GPL-3.0. It can be installed from a Debian package or zip file, with the Nix package manager and a NixOS module, or with Docker. Documentation is published on its website. It suits individuals and small organizations that want a private way to exchange large files.

Uguu is a simple, lightweight platform for temporary file hosting and sharing that can also serve as a permanent file host. Uploading takes one click and needs no registration, and the web interface is minimal and modern, supporting drag and drop, paste and click-to-select. It is aimed at anyone who wants to run their own quick-share service, and a public instance runs at uguu.se.

An upload API can return responses in JSON, HTML, plain text or CSV, and the service works with ShareX and other screenshot tools. Administrators can restrict files by extension or MIME type with black or whitelists, apply upload rate limiting, and blacklist files by hash. The README lists tested requirements of Nginx with PHP 8.3 and SQLite, MySQL or PostgreSQL; Bun is used to compile front-end assets before the app runs on PHP.

Installation and configuration are covered in the project documentation. Uguu is based on the earlier Pomf project, follows the PSR-12 coding standard enforced with PHPCS, and is licensed under GPL-3.0.

FileShelter is a self-hosted web application for sharing files over the internet. You upload one or more files and receive a URL to pass on, which keeps the workflow light for people who want to run their own sharing service instead of using a public one. A public demo instance exists with limits of three days and 1 MB per file.

Shares have a validity period from one hour to many years, optional password protection for downloads and uploads, and hard-to-guess UUID-based links. Multi-file shares are zipped on the fly, and a private edit link lets the uploader remove files or check download counters. It supports customizable terms of service, multiple languages and a command-line tool, fileshelter-cmd, to list, create and destroy shares.

FileShelter is written in C++ with low memory needs, and its demo runs on a Raspberry Pi. After a share expires, files are deleted roughly two hours later so that in-progress downloads are not interrupted. It is released under GPL-3.0, with installation steps in the repository.

YouTransfer is a self-hosted file transfer and sharing application built as an alternative to paid services such as Dropbox and WeTransfer. It is aimed at organizations and individuals who want similar file-sharing convenience but without usage limitations, pricing tiers or a lengthy third-party privacy policy, since files stay on infrastructure the operator controls.

It is designed to be installed behind a firewall on private servers, letting teams combine easy-to-use file transfer with the security and control of self-hosting. A live but limited public demo is available, and the README recommends running it locally for the full experience.

YouTransfer can be installed quickly using a published Docker image, with additional documentation on the project's GitHub Wiki covering installation and usage in more depth. It is written in JavaScript and released under an Apache license. The README explicitly states the project is looking for a new maintainer to update outdated packages, merge pull requests and continue improving it, so prospective users should weigh its current maintenance status.
