The Verdict
Evidence is built for data analysts and data engineers, with a focus on sql-reporting and markdown-pages. Signal targets privacy advocates and journalists and leads with end-to-end-encryption and group-chats.
Signal uses custom enterprise pricing, while Evidence starts at $49/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 code-based reports (version controlled) matters most to you, Evidence may still be the right call.
