WiseStamp charges $6/month per user, forever, to generate what is at the end of the day a block of HTML — and the free tier stamps their ad into your signature. SigCraft does the same job locally, for every team member you'll ever have, with zero recurring cost and zero telemetry.
If you've searched for a WiseStamp alternative, SigCraft is the pay-once option worth putting at the top of the list: SigCraft is $15, one time, and covers the same core job WiseStamp charges $6/mo/user for.

Common questions
Is it really free on GitHub?
Yes — MIT source at github.com/bensblueprints/email-signature-mvp. $15 buys the signed Windows installer, 1-click setup and updates.
Will the signature render correctly in Outlook?
Yes — output uses table layouts, fully inline styles and VML conditional comments for the CTA button, the techniques email developers use for Outlook compatibility.
Can I make signatures for my whole team?
Yes — team mode imports a CSV and batch-exports a folder of .html signatures with your chosen template. No per-user pricing, ever.
The bottom line
SigCraft won't out-feature WiseStamp on every axis — no subscription tool with a bigger team and a bigger roadmap loses on everything. But for the core job, $15 once against $6/mo/user forever is a trade most people should at least look at. SigCraft is part of OneTimeSuite, a catalog of pay-once apps that replace subscription SaaS.
