Nylas

What is Nylas?

Nylas is a powerful unified communications API that lets developers add email, calendar, contacts, scheduling, and meeting intelligence features to their apps—without building integrations from scratch. Instead of wrestling with dozens of different providers like Gmail, Outlook, Zoom, or Microsoft Teams, you get one clean, consistent interface that handles authentication, data sync, and normalization behind the scenes.

Whether you're building a CRM, productivity tool, telehealth platform, or recruiting software, Nylas saves months of engineering time by offering ready-to-use SDKs and real-time data across 250+ email, calendar, and conferencing providers. With enterprise-grade security, 99.99% uptime, and a free developer tier, it’s trusted by over 1,000 companies to power mission-critical communication workflows.
