Hashnode is a blogging platform built for developers and engineers. A writer can open a blog at no cost and connect a custom domain, with the certificate managed by the platform. The editor is designed for technical content: it highlights syntax in 25 programming languages and supports LaTeX, tables and embeds, and raw Markdown can be used in its place. Existing blogs can be imported as Markdown with their tags, dates and canonical URLs preserved, and redirects keep earlier links working. Posts and drafts are mirrored to a GitHub repository, from which publishing is also possible. A GraphQL API sits behind the whole product, so a blog can run headless behind a custom frontend. For AI workflows, Hashnode's own blog announces an MCP server for Claude, ChatGPT and Cursor, a CLI, and an agent skill for publishing. A community feed shows new and popular articles and trending tags. ## Key features - **Technical Writing Editor**: Highlights code in 25 languages and handles LaTeX, tables and embeds, with raw Markdown as an alternative. - **Custom Domain**: Maps a blog to the writer's own domain and takes care of the SSL certificate. - **GraphQL API**: Exposes blog content programmatically so it can power a separately built frontend. - **Agent and MCP Access**: Offers an MCP server, a CLI and a GraphQL skill so AI assistants and coding agents can publish and manage posts. - **Import and Redirects**: Brings in Markdown files with tags, dates and canonical URLs and redirects old addresses to the new blog. - **GitHub Mirroring**: Copies every post and draft to a GitHub repository and can publish from that repository. ## Use cases - **Starting a Developer Blog**: Publish tutorials and engineering notes under a personal domain. - **Headless Blog for a Product Site**: Pull posts through the API into a company website built with its own frontend. - **Migrating From Another Platform**: Move an existing Markdown archive across without breaking links. - **Publishing From an AI Assistant**: Draft and publish a post from an MCP-capable client or a coding agent. - **Following Technical Topics**: Read the feed and trending tags such as web development, TypeScript and DevOps. ## Things to know - **A blogging platform first**: Hashnode's core product is blog publishing; its AI-related features are integrations that let assistants and agents work with a blog. - **Content stays portable**: Posts and drafts are mirrored to GitHub, which the site presents as protection against lock-in. - **Community rules**: Hashnode publishes a code of conduct alongside its terms and privacy policy. ## FAQs ### What is Hashnode?
