Artalk

Artalk is a lightweight, self-hosted comment system designed for personal blogs, documentation sites, and small to medium-sized web applications. Developed by the Artalk team (primarily by a Chinese developer known as qwqcode), it provides a modern, fast, and feature-rich commenting experience that can be deployed on any server with minimal resource requirements. Unlike hosted comment systems like Disqus (which requires third-party accounts, shows ads, and raises privacy concerns), Artalk gives website owners full control over their comment data, with no external dependencies or data sharing. Key features include: a single binary deployment model (the entire backend compiles into one Go binary that includes the web server, database, and admin interface, making deployment as simple as downloading and running), support for multiple database backends (SQLite for simple setups, MySQL and PostgreSQL for larger deployments, and Redis for caching), a built-in admin dashboard for moderating comments, managing users, and configuring the system, multi-site support (a single Artalk instance can serve comments for multiple websites or domains, each with independent configuration), email notifications for new comments and replies, support for Markdown and rich text formatting in comments, social login integration (GitHub, GitLab, Gitee, and others via OAuth), nested comment threads with configurable depth, emoji support with custom emoji packs, image upload support (with configurable storage backends including local disk and Alibaba OSS), comment voting (upvotes and downvotes), anti-spam protection (keyword filtering, Akismet integration, hCaptcha/Cloudflare Turnstile verification), and a lightweight JavaScript embed (under 50KB gzipped) for easy integration into any web page. As of 2026, Artalk has over 2,000 GitHub stars.
