The Verdict
SeaTable is built for privacy conscious teams and european companies, with a focus on spreadsheet-interface and python-scripting. Signal targets privacy advocates and journalists and leads with end-to-end-encryption and group-chats.
Signal uses custom enterprise pricing, while SeaTable starts at $7/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.
Signal edges out on user ratings (4.6 vs 4.2). While both are well-regarded, that gap reflects real differences in user satisfaction worth considering.
Bottom line: Signal has a slight overall edge — but if self-hostable with docker matters most to you, SeaTable may still be the right call.
