Drawing a signature on a PDF is an afternoon. But nobody pays DocuSign to draw squiggles — they pay for the audit trail a court will accept. You can't code your way to legal weight.

The parts this build actually needs, each rated on its own — the average is the Vibe Score above.

| AI agent — with a subscription (Claude Pro/Max, Cursor, etc.) | $0 marginal |
| AI agent — pay-per-use API, no subscription | $86–$172 one-time |
| Hosting, once it's running | $0/mo (free tier) |
| Domain name, if you want your own | ~$12/yr |

For internal, low-stakes sign-offs (club forms, roommate agreements) a simple signing page is genuinely fine — the verdict is about contracts that matter Per-envelope pricing punishes low volume; for a few contracts a year, pay-as-you-go competitors undercut the subscription
