Dokobit vs OpenSign

Dokobit lets users sign documents and collect signatures from others. Its portal supports PDF, ASiC-E, and Baltic BDoc, EDoc, and ADoc files, with signing through national ID cards, Mobile ID, Smart-ID, and other supported eID solutions. Dokobit says its supported electronic signatures are legally binding and accepted across the EU. Portal tools include signature validation, contact categories, search and filtering, comments, batch actions, secure sharing, notifications, and an audit trail. Business features add document workflows, shared resources, user and data management, branded signing, and centralized billing. APIs support signature collection, signing, archiving, timestamping, validation, user identification, and document sealing. The Free plan costs nothing, billed free forever, and includes 3 signatures per month, 3 basic liability document validations per month, and 100 MB storage. Professional is €10 a month, billed per user/month; Business is €22 a month, billed per user/month; Enterprise is €25 a month, billed per user/month. Mobile apps provide portal features and document notifications.

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.
