The Verdict
Immich is built for self hosters and families, with a focus on photo-backup and facial-recognition. Signal targets privacy advocates and journalists and leads with end-to-end-encryption and group-chats.
Signal uses custom enterprise pricing, while Immich starts at $0/mo — a tangible advantage for teams with a fixed budget.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Feature-wise, Immich offers broader built-in capabilities (7 features vs 6), while Signal takes a more focused approach — which can mean a simpler, faster onboarding experience.
This is a genuinely close comparison. If you can, sign up for both free trials (where available) and run a one-week test with your actual team tasks before deciding.
