Fivetran has released its new Connector SDK product into General Availability, offering a seamless experience for building custom connectors, especially when paired with Anthropic's Claude code-writing agent. The team built a custom connector for the PokéAPI to test it out and achieved remarkable results, including creating a fully functional connector with four tables in under an hour and spending only $3.01. They used Claude AI to rapidly create the connector, iterate on the code, test and debug, deploy, and refine the process. The experience showcased the power of combining Fivetran's Connector SDK with Claude AI, making custom connector development faster, cheaper, and more productive.
