What developers are saying

By using Arcade, we're able to authenticate users' Twitter/LinkedIn accounts without worrying about refresh tokens, broken auth, or any of the other hassle that comes with setting up auth connections.

Brace Sproul

AI/ML Engineer, LangChain

Arcade nails the sweet spot between AI, auth, and developer experience. We're using it and it's insanely useful - finally a product that lets AI agents actually do stuff.

Randall Degges

Head of Developer & Security Relations, Snyk

We built an AI sales agent that knows everything about every deal by analyzing calls, emails, and CRM data. With Arcade, that agent can now go the extra mile and effortlessly take secure actions on behalf of a rap - turning a smart assistant into a revenue-driving powerhouse.

Gorish Aggarwal

Cofounder & CEO, Sybill

With Arcade, we can bypass the complexity of Google service integration and fast-forward our AI development to building tools for our AI Assistant that teachers can actually use.
