Key Features

• Embeddable comment widget with nested threads, sorting, pinning, voting, and quick jump/quote navigation
• Moderation tools including spam interception and configurable captcha
• Notifications via email and additional push methods, plus in-site notifications and mentions
• Multi-site support with site isolation and centralized administration
• Markdown support, emoji packs, LaTeX rendering integration, and theming options (including dark mode)
• Image upload support with customization options and client enhancements like lightbox and lazy loading
• Plugin/extension system for adding custom functionality
• HTTP API with OpenAPI documentation for integrations and automation

Use Cases

• Add a privacy-friendly comment section to a personal blog or static site
• Provide discussions and feedback threads for product pages or documentation
• Centralize commenting for multiple sites under one admin and moderation workflow

Limitations and Considerations

• Some features (social login, email delivery, push notifications, captcha) require additional external providers or SMTP configuration

Artalk is a good fit when you want an efficient, customizable commenting layer with modern moderation and notification capabilities, while keeping control over your data. Its small client and Go-based server make it practical to deploy across a wide range of sites and environments.
