SeaNotes is an open-source SaaS Starter Kit developed by DigitalOcean, designed to provide a production-ready foundation for building SaaS applications quickly and efficiently. This starter kit includes essential features like user authentication via NextAuth.js, Stripe billing integration, file uploads using DigitalOcean Spaces, transactional emails through Resend, and a PostgreSQL database hosted on DigitalOcean. Additionally, it offers AI-powered content generation using DigitalOcean's Gradient AI Platform and simplifies deployment with one-click options to DigitalOcean's App Platform. SeaNotes is particularly beneficial for indie hackers, solo developers, early-stage startups, and those looking to validate new ideas, as it handles foundational tasks such as authentication, billing, and UI setup. The kit supports easy customization and integration with large language models (LLMs) for further development, allowing developers to focus on creating unique business logic rather than boilerplate setup.
