Remark42

Value is created by providing a privacy-focused, resource-efficient commenting engine that site owners can self-host instead of relying on third-party hosted comment platforms that track users. The project is distributed as open-source software under the MIT licence, allowing free use, modification and self-hosting. Revenue, where it exists, is generated indirectly through voluntary sponsorship and donations to the maintainers, and potentially through ad hoc support or consulting rather than through a structured commercial product. There is no evidence of a proprietary, paid tier or hosted service operated by the core team.

Remark42 is an open-source, self-hosted commenting engine for websites and blogs. It provides a lightweight comments widget with embedded file-based storage, user authentication, moderation and import/export tools as a replacement for third-party hosted comment systems such as Disqus.

The software is released under the MIT licence and there is no clear evidence of an official commercial SaaS offering. The maintainers appear to rely on community support and voluntary sponsorship (e.g. Patreon, GitHub Sponsors) rather than direct licence or subscription fees. Its users are technically capable site owners, developers and publishers who deploy and operate the software on their own infrastructure.
