Overview

Sanity

Sanity is a customizable content platform that lets you treat your content as structured data. Instead of being locked into rigid page templates, you can build a content model that fits your exact business needs. You can manage your text, images, and other assets in a single location and distribute them to any website, app, or device via a powerful API.

You can collaborate with your team in real-time using the Sanity Studio, an open-source editing environment that you can configure with JavaScript or TypeScript. It solves the problem of siloed content by providing a single source of truth for your entire organization. Whether you are a developer building a custom storefront or a content creator managing global campaigns, you can work simultaneously without overwriting each other's progress.

Substack

Substack provides you with a simple, integrated system to write, publish, and monetize your work without needing technical web design skills. You can start a newsletter for free, build an email list, and eventually turn your hobby into a business by charging for premium content. The platform handles the underlying infrastructure, including hosting, payment processing, and email delivery, so you can focus entirely on your creative output.

You can reach your audience directly in their inboxes while also maintaining a web-based archive of your posts. It is particularly effective for independent writers, journalists, and creators who want to own their audience data rather than relying on social media algorithms. Whether you are starting a small personal blog or a professional media company, you get the tools to manage your community and grow your revenue through a simple revenue-sharing model.
