A SignWell alternative with the API and MCP server in the price
SignWell is the closest in spirit: a simple e-signature tool with a real free plan, priced per sender. Sigil prices per account, counts documents instead of senders, and includes the API and an MCP server from the Pro plan.

Where SignWell is the better choice
- Unlimited documents for one sender at $10 a month: for one busy person, cheaper than Sigil's Starter or Pro.
- API access on every plan, the free one included, with 25 API documents a month free.
- A longer track record and a larger integration list (Zapier and the like).
Where Sigil is simpler
- The API and the MCP server with the plan's documents on Pro, no per-document API fee; an assistant can send and track pacts.
- Documents are counted, not senders: a team shares one Pro account at $18.99 for 100 documents a month.
- Signer pages on your own domain on Pro and up.
- Unlimited templates on every paid plan.
- Glyphs typed into the document, so the file you have is the template; the field editor is there too on paid plans.
Switching from SignWell
Upload the same PDF or Word file, type the glyphs where the fields were (or place them in the editor), and save it as a template. Signed documents stay in SignWell; download the ones you need.
How Sigil works has every glyph; the quickstart sends a first pact from code.
