Shadowly is a web based tool for viewing and analyzing public Instagram and TikTok accounts. For Instagram, it can display profile details, posts, stories, highlights, Reels, and follower and following lists without requiring an Instagram login. It cannot access private accounts and is not affiliated with Instagram. Shadowly states that story views made through the service do not appear in the viewer’s account list because users do not connect their own Instagram accounts. The tool also provides Instagram engagement calculations and creator reports, including engagement rates, content quality scores, profile audits, posting patterns, and estimated collaboration rates. TikTok profile analysis includes account views, engagement information, and top videos. Reports can be shared by link, and engagement comparisons use averages and medians benchmarked by account size. Users typically enter a username or paste a public profile link, then select the profile section or analysis they want to view. Shadowly is accessed through a web browser and requires no installation or account login. Each tool offers a free preview; further use is available through credits, with one credit opening one analysis or profile section for 24 hours.
