Coop
Your NAS, minus the vendor app. Coop puts your Synology in every app's file picker and streams video straight into Shattercut — zero dependencies, no cloud relay, one 44 KB APK that talks to your NAS and to nothing else.
★ Take it home ★
Get Coop
One small APK that signs into DSM's own File Station service — nothing to install on the NAS, no account but your DSM login. Browse shares in a fast native list, tap a video and it opens in Shattercut streaming straight off the NAS, and find the whole NAS in the Open-from drawer of every app on the phone. HTTPS with trust-on-first-use pinning for DSM's self-signed certificate; credentials sealed by the Android Keystore; two-factor handled once with a trusted-device token.
QuickConnect relay is deliberately unsupported — your files never route through anyone's cloud. Use the LAN address, a DDNS name, or your VPN.
★ The numbers ★
Tale of the tape
Coop against the vendor's file app. Their column shifts with every store update; ours is a number you can verify against the signed APK.
★ Fighting weight ★
Small is a feature
The picker is the app
Coop registers your NAS as an Android documents source. Shattercut's Open, mail attachments, any app's Save dialog — the Synology just appears there, next to the phone's own storage. Integration isn't a feature list; it's the architecture.
Streams like it's local
Files stream with ranged reads, so scrubbing a video seeks over the network instead of downloading the file first. A two-gigabyte clip starts playing in the time it takes to fetch its first seconds.
Smaller than one photo it serves
The whole client weighs 44 KB — less than a single snapshot on the NAS it browses. Hand-rolled DSM client, JSON parser, and TLS pinning; nothing imported, nothing along for the ride.
