Most of SendTab's functionality is within an extension for web browsers. The extension lets you share links instantly between computers. You are, in essence, sending tabs from one computer to another, where you can then open up the link to view. You can then return to previously sent tabs through a searchable history, so it's also a bookmarking service.
The SendTab API is RESTful and allows developers incorporate SendTab data into their own applications.
The following is a list of libraries from ProgrammableWeb's Library Directory that matched your search term. Although there many different interpretations of the word "library" among software developers, ProgrammableWeb adheres to a specific definition so as to clearly distinguish libraries from SDKs and frameworks in a way that will facilitate clean search results. In ProgrammableWeb's parlance, the term "library" is strictly used to describe a platform-specific software tool that, when installed, results in the provisioning a specific API. Conversely, SDKs are exclusively for consuming APIs and Frameworks are agnostic to specific APIs. If you think a library, SDK, API, or other asset is missing from our directory, be sure to check our guidelines for making contributions to ProgrammableWeb.
