ファイルをエンドツーエンドで暗号化して送信する、オープンソースのアプリ。どのデバイスにも、リンクで誰にでも送れます。クラウドストレージなし、アカウント不要、サイズ制限もありません。

QRコードまたは短いコードで一度ペアリングすれば、あとはデバイス同士が自動的に認識し合い、ファイルが直接やり取りされます。

リンクを共有するだけで、相手はブラウザからダウンロードできます。インストールもアカウントも不要、あなたのデバイスから直接届きます。
他の選択肢はどれも何かを犠牲にしているからです。AirDropはApple製品同士でしか使えません。WeTransferはファイルをサーバーにアップロード・保存し、無料プランは2GBまでに制限されます。LocalSendとSnapdropは同一ネットワーク内でしか使えません。AlterSendはそのどれの弱点も引き継がず、良いところだけを両立しています ― クロスプラットフォーム、サイズ無制限、クラウドストレージなし。インターネット経由でもWi-Fiと同じくらい簡単に使えます。
暗号化されたリレーサーバーが代わりにデータを中継します。この場合もエンドツーエンドで暗号化されたままなので、リレー側もファイルの中身を見ることはできません。
中断したところから再開します。接続が切れても、ノートパソコンを閉じても、バッテリーが切れても ― 再接続すれば最初からではなく続きから転送されます。
はい。リンクを送るだけで、相手はブラウザから直接ダウンロードできます。インストールも登録も必要ありません。
はい。同じ部屋にいても、遠く離れた大陸にいても、接続は直接行われます。
いいえ。ファイルを保持するクラウドストレージ自体が存在しないため、保存もスキャンもされようがありません。
いいえ。転送がリレーサーバーを経由する場合でも、エンドツーエンドで暗号化されたままです。私たちがそれを読んだり、保存したり、第三者に渡したりすることはできません。
別のデバイスからペアリング一覧を削除するだけです。保存されているのは公開鍵だけなので、ファイルや個人情報が漏れる心配はありません。
支払うべきクラウドストレージ費用がそもそもないからです。AlterSendはオープンソースで、オープンに開発されています。
This app beats Localsend and Blip, and has the potential of becoming really big!
This looks really clean, been wanting something exactly like this for sending large files between my devices without dealing with upload limits.
It's completely free, open source, and works on tons of different platforms. The developer is always making it better.
AlterSend is a free P2P transfer service that allows you to directly transfer large files over the internet or even using only local Wi-Fi. It requires no account, is ad-free, and is compatible with smartphones and PCs.
Cross-platform peer-to-peer file transfer without servers.
Why upload your files to Google Drive, Dropbox, or WeTransfer just to share them once?
No cloud storage. Encrypted. Works locally but also on the internet.

Try AlterSend as well, it is P2P file sharing, very fast and nice pairing between devices (cross-platform).
Supports P2P like Blip, but without an account — seems like best of both worlds.
An alternative to NordVPN Meshnet, thanks.
Cross-platform peer-to-peer file transfer tool, no account required, no cloud relay needed — files of any size can be transferred directly between devices.
This is what WeTransfer should have been: files of any size, directly between devices — no uploading to the cloud, no middlemen, no accounts. 100% private and open source.
A free and open-source LocalSend and WeTransfer alternative for sending large files directly between devices with end-to-end encrypted P2P transfers. Cross-platform, with no accounts, no servers, and no size limits.
It allows for high-speed P2P file transfer between Android, iOS, and PC. It's highly secure due to its serverless and encrypted architecture. It's easy to use. Excellent.

Awesome! I've tried to use Blip in the past, but it's SO buggy and unusable. I'll be trying this out!
Looks amazing — this will be finally the replacement of WhatsApp to transfer files?
Installed to test, so far it's working great.
Cloud storage often gets stuck at snail-paced uploads, and the recipient has to log in just to download. AlterSend focuses on direct file transfers between devices, without going through any cloud server relay.
Peer-to-peer file transfer, end-to-end encrypted, no account, no server, and no size limit. A direct alternative to WeTransfer or Google Drive for those who prefer to keep their files out of the cloud.
I'm using this program on all devices. Thank you for making it.
I really like the experience and share between my devices. Huge advantage is no cloud.
