Nextcloud: Open-Source Cloud Apps

Original Article ↗ Hacker News Discussion ↗

Project Positioning & Philosophy

  • Seen as an open-source alternative to Google/Microsoft cloud stacks, but criticized for “do everything” scope and feature creep.
  • Some praise its role as a central data hub using standard protocols (WebDAV/CalDAV/CardDAV).
  • Others argue the “cloud platform” paradigm is flawed vs. local-first desktop computing.

Common Use Cases

  • Personal cloud for files, photos backup (especially phone camera uploads), calendar, contacts, tasks, and notes.
  • Small orgs and non-profits use it for file sharing, shared calendars, basic collaboration.
  • Some use hosted offerings (e.g., Hetzner Storage Share) to avoid self-hosting complexity.

File Sync & Performance

  • Many complaints: slow, CPU-heavy (especially PHP), poor performance on Raspberry Pi or with S3, WebDAV bottlenecks, struggles with many small files.
  • Some report solid performance with decent hardware, in-memory caches, and tuned setups.
  • Desktop sync praised by some as Dropbox-like; others find it buggy, slow, and inferior to specialized sync tools.

Apps, Photos, and Ecosystem

  • Core file storage and simple office integration (OnlyOffice/Collabora) considered “good enough” by some.
  • Photo handling widely criticized as weak and slow; Memories app helps but is still seen as behind specialized photo solutions.
  • App ecosystem viewed as uneven: convenient but quality varies; extra apps can complicate upgrades.

Client Quality (Desktop & Mobile)

  • Android app often described as unstable, unintuitive, and unreliable for bulk uploads.
  • iOS clients hampered by iOS background restrictions; some call use on iPhone “an exercise in futility.”
  • Desktop client has many open issues; some consider it immature.

Reliability, Upgrades, and Data Loss

  • Multiple reports of painful or failed upgrades, DB corruption, zero-byte files, and even total data loss.
  • Others report years of trouble-free updates, especially with Docker, AIO, or snap installations.
  • Opinion split between “nightmare/unfit for purpose” and “rock solid if you stay close to core features.”

Security & Self‑Hosting Tradeoffs

  • CVE count sparks debate: some see it as evidence of attention and patching; others see insecure legacy PHP.
  • Broader discussion on whether self-hosting can be more secure than big cloud providers; consensus is “it depends on threat model and admin skill.”

Alternatives & Complementary Tools

  • Frequently mentioned: Syncthing, Seafile, OCIS, Radicale, Immich, PhotoPrism, Piwigo, Synology Photos, Etherpad, CryptPad, Collabora, OnlyOffice.
  • Many prefer a toolkit of small, focused services over an all-in-one platform like Nextcloud.
