The development of the new @huly_io landing page involved a comprehensive approach, encompassing branding, design, development, and motion design, with a total cost of $89,775. The project aims to replace multiple tools like Linear, Jira, Slack, and Notion by providing an all-in-one open-source platform (Huly.io). This includes collaboration, project management, communication, and note-taking functionalities in one integrated solution.
