5 Free & Open-Source Alternatives to DocuSign

Looking for a free or open-source alternative to DocuSign? Inkseal is the closest direct swap — MIT-licensed source on GitHub, or a $59 one-time packaged install. Since you're already auditing what you pay DocuSign 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. Inkseal — replaces DocuSign

Upload a PDF, place fields, route signers, get a flattened audit-trailed document — on your own box. First document free. $59 once vs DocuSign's $10/mo. Free on GitHub, or the packaged installer on Whop.

Replaces Keygen (from $99/mo). $49 once. See Keymaster →

4. Ledgerlite Home — Local-first zero-based budgeting with CSV import, payee rules and net-worth tracking.

Replaces YNAB ($14.99/mo). $15 once. See Ledgerlite Home →

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 DocuSign — they're trying to be the last subscription you pay for that specific job.
