Could you build this?
Partial Basic OAuth flows and a settings UI can be vibe-coded, but reliably supporting and maintaining 200+ distinct third-party API integrations, token lifecycle management, webhooks, and rate-limit backoffs at scale is a complex distributed systems effort.
What it would actually take: Building an integration engine like Nango or Corsair involves an execution engine (Node.js/Go/Temporal) managing multi-tenant OAuth2 tokens, encrypted secrets storage, webhooks ingestion, and schema normalization across 200+ third-party SaaS APIs. The hard part is dealing with continuous API version drift, complex pagination/rate-limiting regimes, reverse ETL syncing, and sandboxed code execution for custom connectors. It requires dedicated integration maintenance engineering and robust distributed job orchestration.
