Nextcloud: Open-Source Cloud Apps

Original Article ↗ Hacker News Discussion ↗

Self‑hosted cloud platform Nextcloud draws both praise as a privacy‑respecting alternative to Google Drive/Dropbox and sharp criticism for bloat, performance problems, and fragile upgrades. Many users value its all‑in‑one approach for files, calendars, contacts, and collaboration—especially in regulated or Microsoft‑averse environments—while others report data loss, slow web and sync clients, and unstable mobile apps, preferring focused tools like Syncthing, Seafile, Immich or Photoprism instead. A recurring theme is the trade‑off between the convenience of a “do everything” PHP platform and the security, reliability, and simplicity of smaller, single‑purpose services.

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.
