ContractClaw Sign has zero per-document fees on all plans. Competitor pricing based on published rates.
We started by integrating DocuSeal — an open-source e-signature tool. The self-hosted version was free, but the moment we needed API access for our AI agents, costs jumped to $20/month plus $0.20 per document. At 1,000 documents per month, that is $220 in API fees alone — more expensive than DocuSign.
We then evaluated Documenso, another open-source option. Within a week of integration, we encountered four critical bugs: failed webhook deliveries, broken multi-party signing flows, timestamp inconsistencies, and silent PDF rendering failures. Rather than patching someone else's codebase forever, we built ContractClaw Sign from scratch — with OTP verification, QR codes, RFC 3161 timestamps, and AI agent signing as first-class features. Zero per-document fees. Zero compromise.
