Overview
OneSpan Sign
OneSpan Sign helps you move away from paper-based processes by providing a secure way to sign, send, and manage documents electronically. You can create automated workflows that guide signers through every step, ensuring no fields are missed and documents are returned complete. Whether you are closing a loan, onboarding a new employee, or signing a sales contract, the platform provides a consistent experience across web and mobile devices.
You can protect your business with comprehensive audit trails that track every action taken during the signing process. The platform is designed to meet strict global compliance standards, making it a reliable choice for highly regulated industries like banking, insurance, and government. You can choose between flexible deployment options, including public cloud, private cloud, or on-premises, to match your specific security and data residency requirements.
Supabase
Supabase provides you with a complete backend platform built on top of enterprise-grade open-source tools. Instead of spending weeks configuring servers and writing boilerplate code, you can spin up a dedicated PostgreSQL database in less than two minutes. It automatically generates REST and GraphQL APIs based on your database schema, allowing you to start building your frontend immediately without manual backend plumbing.
You can manage user signups with built-in authentication, store large files in S3-compatible storage, and write custom logic using edge functions. The platform handles the heavy lifting of scaling and security, so you can focus on creating your product. Whether you are building a simple MVP or a complex enterprise application, it offers the flexibility of SQL with the speed of modern serverless development.
