In their own words
Dropbox Sign
Dropbox Sign is an e-signature service for individuals and businesses managing online agreement workflows. It supports sending signature requests, tracking them, and sending reminders. Signatures are legally binding under the U.S. ESIGN Act of 2000, with the same legal standing as pen-and-paper signatures. Templates save prepared fields for documents sent repeatedly, and embedded signing lets signers complete the process within a website. The API uses OAuth 2.0 and has official SDKs for Python, Ruby, PHP, Java, NodeJS, and C#. It also offers an audit trail and identity verification; bulk sending is not available. Senders and signers can use 22 languages, with apps for iOS and Android as well as web and API access. Listed integrations include Google Workspace, Microsoft Word, Salesforce, HubSpot, Slack, and Zapier. Dropbox Sign states that it complies with SOC 2 Type II, ISO 27001, eIDAS, and GDPR, and encrypts documents at rest with AES 256-bit encryption. A free plan allows three signature requests per month. Paid plans start at $10.05 a month with annual billing, and a 30-day trial is listed.
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.
