In 2024, B2B SaaS companies prioritize native integrations with customers' key business tools. Rutter's unified API has alternatives like Nango, which offers a comprehensive integrations platform with over 4,800 GitHub stars and supports more pre-built integrations across various categories. Apideck provides pre-configured integrations for CRM, accounting, and HRIS APIs, while Codat caters to fintech companies with banking and commerce tools. Building integrations in-house can provide full control but comes with hidden costs and challenges. Nango is considered a great alternative to Rutter due to its flexible platform, developer-first approach, comprehensive support framework, and scalable infrastructure.
