Koji

Koji takes a fundamentally different approach to the link-in-bio category by turning your profile page into an interactive app platform.

Instead of a static list of links, Koji lets you embed "mini-apps" directly into your bio page, including tip jars, trivia games, Q&A sessions, custom storefronts, polls, and dozens of other interactive experiences.

For creators who want to engage their audience rather than just direct them, Koji provides tools that no other link-in-bio platform offers. The platform's mini-app ecosystem is its core differentiator.

Koji offers a growing library of pre-built apps that you can customize and drop into your page.

These range from simple commerce apps (sell digital files, accept tips, offer shoutouts) to engagement-focused apps (run polls, host quizzes, collect fan messages) to gamified experiences that encourage repeat visits.

The app-based model means your link-in-bio page can evolve and stay fresh without redesigning anything. Koji is free to use, with the platform taking a small percentage of transactions when you use commerce-related mini-apps.

The customization options for the page itself are solid, with themes, colors, and layout controls. However, the platform is still building its user base and ecosystem, and some mini-apps feel more polished than others.

For creators on TikTok, Instagram, or YouTube who want their bio link to be an experience rather than a directory, Koji offers creative possibilities that static link-in-bio tools cannot match.
