What real users say: Frona vs Spider Cloud

Frona

32 mentions across 4 sources · 32% positive — critical (weighted across 4 sources)

Hacker News, YouTube, GitHub, Lemmy

What users praise

  • • Network sandboxing with domain allow/block is a real differentiator no cloud assistant offers
  • • Vault-backed credentials via 1Password, Bitwarden, HashiCorp Vault, and KeePass keep secrets out of LLM context
  • • Per-sandbox CPU, memory, and disk limits prevent runaway agents and surprise cloud bills
  • • Maintainers close reported issues within days — nine sampled issues all resolved promptly

What frustrates them

  • • Near-zero independent community coverage — no Reddit, Product Hunt, or Stack Overflow discussion exists
  • • Fresh Docker installs have required disabling the sandbox and manual permission fixes
  • • Tailscale Funnel and Serve exposure is undocumented and blocked by the sandbox by default
  • • Editing the model retry backoff crashed the service into a non-restartable state
