In their own words
Documenso
Documenso provides electronic signature workflows for creating, sending, and signing documents. Reusable templates can be shared through direct links for on-demand signing, and its API can create documents and trigger custom workflows, including user management. Webhooks automate notifications and updates through event triggers. Signing workflows can be embedded and white-labeled, including in React and Vue applications; Documenso also lists Zapier connections. The product describes itself as open source and says it shares its code, designs, and metrics. Its compliance page marks the U.S. ESIGN Act, UETA, eIDAS SES, 21 CFR Part 11, SOC 2, and HIPAA as compliant. ISO 27001, ZertES, eIDAS AES, and QES are listed as planned for 2026. Documenso is available on the web, by API, or self-hosted on a customer's infrastructure. The Free plan allows five documents per month and up to 10 recipients per document. Individual costs $25.00 per month billed yearly; Teams costs $40.00 per month billed yearly.
OpenSign
OpenSign is an open-source PDF e-signature solution for signing, storing, and securing documents. Users can create reusable templates with pre-placed widgets and send them through the API to one or many signers. API workflows include self-signing, drafts, signer roles, public template links, and real-time webhook notifications. Templates can be embedded in React, Next.js, HTML, JavaScript, and Angular projects. The documentation lists TLS-encrypted transport, audit trails, IP logging, and tamper-evident signed PDFs; account protection includes two-factor authentication and passkey sign-in. The free plan costs nothing and lists unlimited digital signatures and templates, completion certificates, sequential signing, OpenSign Drive, and email notifications. Its free-plan guide limits invitation emails to 15 per month; bulk sending and public links require a paid plan. Live API tokens require Professional or Teams, though sandbox tokens are available on all plans. OpenSign provides Docker self-hosting instructions for Linux, macOS, and Windows. Some SMTP features are limited to paid plans.
