Nango is an open-source platform for building, running, and maintaining product integrations with AI, supporting over 800 APIs and handling authentication, execution, scaling, and observability.
Why it matters
Stork Quadrant
Replaceable as a UI, but kept alive as the API the agents call.
“Nango's core value is orchestrating multi-step API workflows—auth, credential rotation, retry logic, webhook coordination—that an LLM can't execute alone without persistent infrastructure. But the 800 connectors and integration templates are pure code that Claude can generate in minutes. The defensibility lives entirely in being the execution layer, not the design layer. If Nango becomes invisible plumbing that agents call (not a UI developers configure), it survives.”
An LLM alone could replace
Stop competing on connector breadth—that's a losing game against LLM code generation. Own the execution guarantees: become the system that agents trust to retry failed API calls, rotate credentials safely, and maintain audit logs for compliance. Lean into coordination moat by making Nango the required middleware for multi-party workflows (agent + user + external API), not just a connector library.
