Google Photos vs PhotoRoom

Google's Photos APIs let apps read from and write to a user's Google Photos library across three products: the current Picker API lets a user securely choose individual items to share without granting an app full library access, the older Library API supports app-driven uploads and management of app-created content (several of its broader read scopes were removed on April 1, 2025), and the newer Ambient API drives slideshow experiences on photo frames and connected TVs. Every product requires OAuth2 user consent — there is no server-only API-key path — governed by Google's Photos API User Data and Developer Policy. Usage is free, bounded by per-project quotas that vary by product (for example 100,000 requests/minute for the Picker API versus 10,000/day for the Library API).

PhotoRoom's API takes a product or portrait photo and returns a background-removed, background-generated, or otherwise edited image via a single multipart POST, authenticated with an x-api-key header per its docs at docs.photoroom.com — a separate GitBook site from the marketing homepage. A live CORS preflight against its segmentation endpoint reflected two different arbitrary Origin headers back with credentials enabled, so browser-side calls are supported directly. New accounts get a 1,000-image sandbox allowance for testing plus limited free production calls to the Remove Background endpoint, with paid plans covering higher volume and the full Image Editing API.
