System Requirements Document for generatesbanner

1. Introduction

The project "generatesbanner" is a micro SaaS modeled on Bannerbear, designed to provide a backend API for auto-generating images and videos for integration with other applications. The product is intended to be operated by a solo founder and aims to deliver a reliable and systematic service to developers and application integrators. The API is positioned as an underrated infrastructure service, generating approximately $1M/year in revenue.

2. System Overview

The generatesbanner product is a backend API service that auto-generates images and videos for use by other applications. The service is designed to be operated by a solo founder and targets developers and application integrators who require media generation capabilities without building the backend themselves. The system includes a public entry page, a login interface, an API console for customers, and an operations workspace for the founder. The product emphasizes systematic product craft with a unique character, avoiding a generic SaaS appearance.

2a. Product Interpretation and Delivery Boundary

The generatesbanner product is delivered as a backend API, with a focus on auto-generating images and videos. It is not a flashy front-end product but rather a functional and reliable service for developers. The product includes a public-facing landing page, a login page for identity verification, an API console for customer interactions, and an operations page for the founder. Access to the API console and operations page is protected and requires login verification. The product is designed to be operated by a solo founder, with no additional user management capabilities.
