Components customers embed via iframes, blocks, or script tags inside the host product.
3 marketplaces in this directory match this tag.
Widgets and embeds — Notion Marketplace, Miro Marketplace, Trello Power-Ups — are components customers place directly into their own pages, boards, or cards, typically via an iframe or block reference rather than a full installed application. It is a lightweight way to add live, interactive content to someone else’s workspace.
Trello Power-Ups use a mostly front-end iframe model with simple API-key auth for backend calls; Notion and Miro widgets sit inside a broader OAuth 2.0 app model. All three reward a narrow, focused widget over a broad feature set — the value is being useful in the exact spot the customer already looks.
