APISign vs DocuSign
Legally binding e-signatures from code, priced per contract instead of per plan. No subscription, no seats, no envelope allowance to size.
APISign
DocuSign
Where DocuSign may be more than you need
DocuSign is the most complete e-signature platform there is. For a developer sending contracts from code, these are the trade-offs:
A plan before your first send
DocuSign's API plans start at $50/mo, billed annually, for 40 envelopes a month. You pay for the allowance whether or not you use it.
Built for large organizations
DocuSign's breadth is real value for enterprises. If you only need to send a contract from code, much of it goes unused.
Per-user app plans
DocuSign's eSignature app plans are $30-$45 per user per month on annual billing, so team size drives the bill. APISign has no per-seat charge.
Why APISign can be the better fit
We built APISign for developers who need simple, affordable e-signatures without the enterprise overhead.
Pay per send
$0.25 per send, and a resend counts as a send. Test sends are free. No subscription, no seats.
REST, MCP and CLI
A REST API with an x-api-key header, a remote MCP server with 12 tools for AI agents, and the apisign-io CLI.
Markdown templates
Define contracts in Markdown with {{variables}}, or import a .docx. No proprietary document builder to learn.
