Nexo
Self-hosted S3 storage that streams video and resizes images
Self-hosted, S3-compatible object storage in one Go binary. Upload an MP4 and it streams as HLS at once; upload a photo and one URL serves AVIF, WebP or JPEG at the right size. Open source, one drive to a cluster.
Why I built it. Every project I worked on needed the same three things: somewhere S3-compatible to put files, a way to stream the videos, and images resized for every screen. That usually means object storage + a transcoding service + an image CDN, three bills and three things to keep running. Nexo puts them in one self-hosted binary.
What it does
🪣 Real S3. It passes all 451 applicable Ceph s3-tests and all 638 MinIO mint tests, so aws, rclone, your SDKs and backup tools just work.
🎬 Video that plays on upload. An MP4 streams as HLS immediately. Tick “HLS” when you create a bucket and a worker adds every quality from 240p to 4K, a poster and seek-bar thumbnails. There’s no ffmpeg, and it uses every core (1080p → 3 renditions at 3.2× real time).
🖼️ One URL, every format. Upload a photo and the same URL returns AVIF, WebP or JPEG depending on the browser, at the width you ask for with ?w=. It works on your own domain with a built-in edge cache.
🛡️ Built not to lose data. Erasure coding, bitrot checks, automatic healing, versioning, object lock and encryption (SSE-S3/KMS/C).
🖥️ Batteries included. A web console, a CLI, Prometheus + Grafana, Docker, Helm, deb/rpm, and binaries for Linux, macOS and Windows.
Coming from MinIO? There’s a step-by-step migration guide, and nexoctl diff verifies every object and version afterwards.

Who hunted Nexo?
Nexo was hunted by Paolo Russo. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
