Opal Editor is completely free to use and own with absolutely no profit motive or incentive. Beyond creating a feature-rich Markdown editor and publisher for the open-source community, it also serves as a way for me to showcase my skills as a developer.
If you like what you see and would like to discuss an opening at your company/startup/workshop, feel free to reach out via my website or by email.
Enjoy!
