Heylink is a service that enables users to create a central hub for all their important links, known as a bio link or link-in-bio tool. It allows individuals, influencers, and businesses to consolidate multiple links under one URL, which can be easily shared across social media platforms and other digital spaces. This is particularly useful for social media profiles that offer limited space for links, such as Instagram or TikTok. Users can customize their Heylink page with branding elements, link management features, and analytics to track the performance of their links.
