SigCraft vs WiseStamp: Open Source vs Subscription

SigCraft and WiseStamp solve the same problem from opposite directions: one is source-available software you can own outright for $15, the other is a subscription at $6/mo/user run entirely on someone else's servers.

What SigCraft does well

  • 10 polished templates — Classic, Modern Sidebar, Minimal, Bold Accent Bar, Card, Compact, Corporate, Creative, Photo Left, Photo Top.
  • Email-safe HTML — Table layouts, 100% inline styles, Outlook (VML) conditional comments — renders correctly in Gmail, Outlook desktop & web, Apple Mail, Thunderbird.
  • Headshot / logo upload — Drag & drop, auto-resized and embedded as base64 — or use a hosted image URL for maximum client compatibility.
  • 12 social networks — LinkedIn, X, Facebook, Instagram, YouTube, TikTok, GitHub and more — brand-colored or monochrome pure-HTML badges, no broken-image icons.

What WiseStamp still does better

There's a real reason WiseStamp costs what it does: a bigger team, broader integrations and dedicated support behind it. If that ecosystem is genuinely what you need, it's worth paying for.

Which one should you pick

If your workflow depends on WiseStamp's specific integrations or you'd rather not run anything yourself, stay put — that's a legitimate call. If you're comfortable owning the tool and want to stop paying $6/mo/user for a job your own hardware can do, SigCraft pays for itself and then some: three months of WiseStamp for one user costs more than SigCraft does for your whole team, forever.
