Airtable is a cloud collaboration service headquartered in San Francisco. It was founded in 2012 by Howie Liu, Andrew Ofstad, and Emmett Nicholas. It aims to improve productivity and organizing data.
Airtable is a spreadsheet-database hybrid i.e., the features of a database are applied to a spreadsheet. The fields in an Airtable table are similar to a cell of a spreadsheet but have the power to do lot more than just hold text. The fields can have file attachments like images, check-boxes, phone numbers, drop-down lists, etc.
After registering to use the site, users can create a database, set up field types, add records, link tables, collaborate with a team, sort the records based on a field and publish views to external websites. When an Airtable database is created, it is automatically hosted to the cloud. The values in the fields are updated real time.
