Airtable has evolved into a versatile platform for developers, offering a range of tools including scripting, a custom apps SDK, automations, and a REST API, enabling the creation of applications both inside and outside the Airtable interface. Developers can use scripts and automations for in-app functionalities, while the REST API facilitates external integrations, albeit with limitations like rate limits and schema constraints. The App SDK allows for more complex React.js applications with capabilities such as schema manipulation and user permissions. Additionally, third-party services like Sequin can sync Airtable data to a Postgres database for more efficient data handling using SQL. These tools collectively empower developers to build scalable and flexible applications, enhancing Airtable's utility far beyond its initial offerings.
