The Verdict
Grist is built for developers and data teams, with a focus on relational-data and python-formulas. Signal targets privacy advocates and journalists and leads with end-to-end-encryption and group-chats.
Signal uses custom enterprise pricing, while Grist starts at $10/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.
Bottom line: Signal has a slight overall edge — but if fully open-source (apache 2.0) matters most to you, Grist may still be the right call.
