Our verdict on CloudSponge
CloudSponge provides a contact picker and REST address-book API for websites and web applications. It is aimed at developers adding contact selection to recipient lists or flows such as referral forms, invitations, e-cards and find-a-friend onboarding. Users can connect an address book, search and select contacts, and pass chosen data into an application. The product fits teams that need this specific contact workflow rather than a broad set of unified APIs across unrelated services.
The integration surface centers on address-book sources including Google Contacts, Yahoo, Outlook.com, Office 365, iCloud and AOL. Developers can embed the JavaScript picker or build a custom interface with the RESTful contacts API. Imports can run asynchronously with event polling, while selected or imported data can be POSTed to configured webhooks; JavaScript callbacks and picker customization options provide additional control. WordPress, WooCommerce and Zapier are also listed as integration options. This makes CloudSponge a fit when the application needs contact selection and a way to route that data into its own flow, but it is a narrower choice than a general-purpose unified API platform.
Pricing is paid, with no free plan and a 14-day free trial. Launch is $99 per year and includes the Universal Contact Picker. Growth costs $69 monthly or $759 annually and adds the Privacy Compliance Service. Branded costs $189 monthly or $2,079 annually, with custom stylesheet and fonts, custom languages and labels, and branding. The vendor lists GDPR compliance, cloud deployment, and email and community support. Choose CloudSponge when embedded address-book selection is the requirement; teams needing self-hosting or a wider range of API categories should look elsewhere.
