Hashnode

Hashnode is a free content creation platform where developers can start and manage blogs on their own domain. You get a powerful editor that supports both Markdown and visual editing modes, making it easy to write technical articles with code blocks, images, and embedded content. The platform handles all the technical details like hosting, SSL certificates, and CDN delivery automatically.

You can customize your blog appearance, connect it to your domain, or start with a free Hashnode subdomain. The platform includes AI-powered writing assistance to help with drafting, editing, and optimizing content. There are paid plans for teams that need collaboration features, advanced analytics, and priority support. Individual creators can use all essential features completely free.

Fern

Fern is a platform that automatically generates SDKs and API documentation from your API definition. You provide your OpenAPI, AsyncAPI, or gRPC specification, and Fern creates ready-to-use client libraries in languages like TypeScript, Python, Go, Java, Ruby, C#, PHP, and Swift.

The platform also builds documentation websites that look professional and match your brand identity. These sites include interactive API references, code examples, and a playground where developers can test your API without leaving the documentation.

Fern is open source and available on GitHub. It integrates with your existing workflow by publishing SDKs directly to package registries like npm and PyPI. The tool is designed for companies that want to provide a great developer experience without dedicating engineering resources to manual SDK maintenance.
