Looking for a free or open-source alternative to WiseStamp? SigCraft is the closest direct swap — MIT-licensed source on GitHub, or a $15 one-time packaged install. Since you're already auditing what you pay WiseStamp every month, here are four more pay-once tools from the same catalog worth a look while you're at it — different jobs, same idea: buy the software once instead of renting it forever.
1. SigCraft — replaces WiseStamp
Email-safe HTML signatures with 10 templates and team CSV batch export — 100% local. $15 once vs WiseStamp's $6/mo/user. Free on GitHub, or the packaged installer on Whop.

Why this list is worth bookmarking
Every app above is a one-time purchase with MIT-licensed source, no accounts with us and no telemetry. None of them are trying to be the next WiseStamp — they're trying to be the last subscription you pay for that specific job.
