Open-source Imgur alternatives

Lychee is a free, open-source photo management tool that runs on your own server or web space. You can upload, manage and share photos through a web interface that is meant to feel like a native application, with the aim of keeping the photos stored securely.

Installation is described as quick, and the project provides Docker images, with version 7.0 bringing significant changes to the Docker image and an upgrade guide. Lychee requires PHP 8.4 or 8.5 and has documentation, a changelog and a Discord community. It is built with PHP, TypeScript and Vue.

Lychee is licensed under MIT. A Supporter Edition adds extra functionality for people who want more than the free version, and users can also support the team directly. Topics on the repository describe it as a photo gallery and photo management application.

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.

Slink is a self-hosted image sharing platform that gives you control over how your pictures are stored and shared, without depending on a third-party host. It is built with Symfony and SvelteKit, and the project tags it as an Imgur alternative for people who want private galleries and links.

Shares are private by default and reachable only through their link, with optional password protection and expiry times, plus a page for listing, editing, publishing and revoking them. Collections group images under one link, and an Explore page shows publicly visible images. It handles many image formats, parallel multi-file uploads, compression and duplicate detection, supports guest uploads, and integrates with ShareX for screenshots. Storage can use S3 or SMB.

Slink is licensed under AGPL-3.0 and delivered as a Docker deployment, with documentation and a live demo online. It supports OIDC single sign-on, which makes it practical for homelabs and small teams. The README says it suits artists, developers sharing screenshots and anyone who wants image privacy under their own control.

tgState, listed here under the author's name Csz, is a self-hosted service written in Go that stores uploads in Telegram and serves them back through external links. It can act as an image host or as a simple network drive, and the project states that it places no limits of its own on file size or format.

Files can be uploaded through a web page or by sending them directly to the Telegram bot, and the bot can return a file ID that you append to your server address to reach the resource. Configuration covers a target (channel, group or user), the bot token, an optional access password, a mode that selects network-drive behavior or disables web upload, a base URL and a custom port. An HTTP API accepts form uploads, and a PicGo uploader setup is documented.

It is MIT licensed and can be deployed as a prebuilt Linux binary for amd64 or arm64, as a Docker container, or on Vercel, though the Vercel deployment cannot handle files larger than 5 MB. A guide for putting it behind Cloudflare is included. It suits individuals who want simple file or image hosting backed by their own Telegram bot.
