DataFaucet generates custom MCP servers from any web application by capturing live API traffic. ACI.dev provides pre-built integrations for 200+ popular services through a unified API. DataFaucet works with any app including internal tools. ACI.dev works only with services they have built connectors for.

Can I use DataFaucet and ACI.dev together?

When to choose DataFaucet

You need to connect AI to internal tools, admin panels, or private apps
The app you need is not in ACI's pre-built catalog
You want to capture custom API actions beyond what pre-built connectors offer
You work with SSO, session-based auth, or complex login flows

When to choose ACI.dev

You only need popular services (Slack, GitHub, Google, Salesforce)
You want managed OAuth token refresh without re-authentication
You prefer a unified SDK for LangChain or CrewAI integration
You want all integrations through a single endpoint

The core difference

ACI.dev builds and maintains individual connectors for each service. This means polished integrations with managed auth for supported apps, but you are limited to their catalog. If the app you need is not listed, you wait until they build it.

DataFaucet takes the opposite approach: instead of pre-building connectors, it captures API traffic from any web app you can browse. This means any app works on day one, including internal tools that will never appear in a pre-built catalog.

For teams that use a mix of popular SaaS and custom internal tools, both complement each other. ACI.dev for the big platforms with managed OAuth. DataFaucet for everything else.
