Honest answers
Is there a free option?
Yes. SigCraft — like every app in the suite — has a free, MIT-licensed MVP on GitHub (https://github.com/bensblueprints/email-signature-mvp). Buying gets you the signed installer, one-click setup and updates; the source is free forever.
Which one should I pick?
Pick by where you want the software to live. SigCraft, Postbird are desktop apps — everything runs locally on your machine, so your files stay private and the app works offline. Either way, every option here is a one-time purchase with MIT-licensed source on GitHub.
Are these really one-time?
Yes. Every app on this page is a single payment — SigCraft is $15, Postbird is $149. No renewal, no seats, no usage meter. The apps keep working even if you never pay again.
