Cost-Effective, Embeddable Integration Hub for Developers

The user is building an app and needs 'connections' functionality (like Notion/Replit connectors for Gmail, Canva, etc.), specifically asking for cheaper or open-source alternatives. This is a common pain point for developers and product teams: integrating with third-party services is complex and existing solutions (like Zapier for end-users, or enterprise iPaaS) can be too expensive or overkill for developers wanting to embed integrations directly into their own products. A SaaS product could provide a developer-friendly, cost-effective integration hub. It would offer a library of pre-built, robust connectors with a unified API, simplified OAuth/authentication flows, webhook management, and clear, usage-based pricing. This targets startups, indie hackers, and mid-sized companies looking to add native integrations to their applications without significant engineering overhead or high recurring costs.
