The real cost of self-hosting
"Free" open source software isn't always free when you factor in the total cost of ownership:
Infrastructure management
Self-hosting means managing servers, databases, backups, and scaling. That's DevOps overhead your team may not want.
Security responsibility
You're responsible for security patches, SSL certificates, and keeping the system hardened. E-signatures require trust.
Ongoing maintenance
Updates, bug fixes, and feature additions require your team's time. Open source doesn't mean zero cost.
Why teams choose managed
With APISign, you get all the benefits of a purpose-built e-signature platform without the operational burden.
Zero infrastructure
We handle hosting, scaling, backups, and security. You just use the API. Focus on your product, not ours.
No seats to buy
Anyone on your team can use the API, MCP server or CLI. There is no per-seat charge; you pay per send.
Predictable costs
$0.25 per send, and a resend counts as a send. Test sends are free. No servers to budget for.

The honest cost comparison
For a team sending 500 contracts/month through an API, at list prices
APISign
DocuSeal Cloud API
At this volume DocuSeal's cloud API is about $5/month cheaper, and self-hosting the open-source edition can cost less still if you already run the infrastructure. Choose APISign for what's different: no seats to buy, Markdown templates you keep in your repo, and nothing to host.
