In their own words
Autenti
Autenti is a paid digital document workflow platform for electronic signatures, identity verification, e-seals, e-delivery and API connections. It runs on the web, iOS and Android, and offers Simple, Advanced and Qualified Electronic Signatures compliant with eIDAS. Senders choose signers, set a sequential order and collect multiple signatures on one document. Folders, workflow templates, notifications and reminders organize pending work. Recipients can sign without an account, payment or software installation, using an internet-connected device. The mobile app provides archived-document access, signing and initials, status tracking and fingerprint-protected access. Autenti lists Salesforce, Zapier, Microsoft Teams and PeopleForce integrations, plus an open API. Its stated security measures include encrypted, georedundant cloud storage, TLS 1.2 or higher, HSTS and Authenticated Origin Pulls. Pricing starts from €30/user/mo with a 14-day trial; there is no free plan. The listed PRO plan is €20 a year (billed 20 EUR net/mo; 240 EUR net billed annually), with unlimited documents and one seat.
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.
