Nylas
The data layer behind every communication workflow, human or AI
Nylas is a communications data platform that gives applications a single API for email, calendar, and meeting data across more than 250 providers, including Gmail, Microsoft Graph, Exchange, and IMAP servers. It addresses the complexity of building and maintaining separate integrations for each provider by handling OAuth, token management, and data normalization, returning a consistent JSON schema with two-way sync.
Core components include the Email API for sending, receiving, threading, and parsing messages; the Calendar API with bidirectional sync and an embeddable Scheduler for booking; Virtual Calendars for resources without provider accounts; Agent Accounts that provision an inbox and calendar for AI agents; and a Notetaker API that joins Google Meet, Teams, and Zoom to deliver recordings, transcripts, summaries, and action items via webhook. An MCP server provides typed tools for email, calendar, contacts, and Notetaker in MCP-compatible clients. Real-time webhooks, SDKs for Node.js, Ruby, Python, Kotlin, and Java, a developer dashboard, and sandbox environments support integration work.
Nylas is aimed at developers and product teams building communication features or agentic workflows into SaaS applications. It offers a free developer plan with full API access and support for up to five connected accounts, with no credit card required; additional plans are available for expanded use.
