Recal.dev

Product Introduction

1. Recal.dev is a calendar and scheduling integration platform that enables developers to embed cross-provider calendar management and booking systems into applications using a unified API. It abstracts complexities like OAuth flows, event synchronization, and provider-specific API differences while supporting Google, Outlook, and other calendar services. The solution offers both a managed TypeScript SDK and an open-source scheduling package, catering to diverse implementation preferences.
2. The core value lies in eliminating 3+ months of integration work typically required to support multiple calendar providers, allowing teams to ship production-ready scheduling features in days. It handles scalability challenges with bulk operations for thousands of events, millisecond-response webhooks, and enterprise-grade reliability (85% uptime SLA), having already processed 51M+ events and 92K+ agent-managed bookings.

Main Features

1. The Unified Calendar API provides standardized REST endpoints for creating/updating events across Google, Outlook, and other providers, with meta-event IDs enabling cross-platform operations. It includes webhook support for real-time updates, timezone-aware scheduling, and bulk import/export tools capable of processing thousands of events per request.
2. The TypeScript SDK (npm install recal-sdk) offers pre-built methods for availability checks, conflict resolution, and OAuth token management, with automatic retries for rate-limited provider APIs. It includes comprehensive TypeScript definitions, organization-level user nesting for multi-tenant systems, and SOC2-compliant encryption for stored credentials.
3. Machine Call Protocol (MCP) enables LLM integration through natural language tool calls, allowing AI agents to execute calendar operations like "Find available slots next week" or "Book 30-minute meeting with sales." This supports voice assistants, customer service bots, and other AI-native interfaces without custom parsing logic.

Problems Solved

1. Recal.dev eliminates the need to maintain separate integration codebases for Google Calendar API, Microsoft Graph API, and other provider-specific interfaces, which often require ongoing updates for OAuth changes and rate limiting. It solves timezone synchronization errors and event formatting discrepancies across platforms through normalized data models.
2. The platform primarily serves SaaS product teams building scheduling features into marketplaces, HR tech platforms, AI agent systems, and enterprise workflow tools. Technical decision-makers at companies needing to embed calendar interoperability without dedicating engineering resources to provider API maintenance benefit most.
3. Key use cases include enabling beauty marketplaces to coordinate appointments across salon Google Calendars, helping recruiting platforms schedule multi-interviewer technical assessments, and allowing AI sales bots to book demos directly into prospect Outlook calendars while avoiding double-booking.

Unique Advantages

1. Unlike Nylas or Cal.com, Recal.dev combines managed API reliability with open architecture - developers retain direct access to raw OAuth tokens for fallback operations while using abstraction layers. The platform avoids UI/UX constraints by focusing solely on API-level integration, enabling custom frontend implementations.
2. Proprietary innovations include Meta Event IDs that unify duplicate entries across connected calendars and organizational hierarchy support for enterprise multi-tenancy. The upcoming SOC2 certification (October 2025) and built-in usage analytics dashboard provide compliance and insights without additional engineering effort.
3. Competitive differentiators include provider-agnostic webhooks with <100ms trigger times, granular OAuth permission scoping per integration, and pricing that automatically increases discounts as usage scales. Developers can override API defaults through escape hatches while maintaining core platform benefits.

Frequently Asked Questions (FAQ)

1. How does Recal.dev handle OAuth token management? The platform automatically manages OAuth 2.0 token acquisition, refresh cycles, and storage with AES-256 encryption, while allowing developers to retrieve raw tokens via API for custom workflows. Provider-specific consent screens can be white-labeled through custom redirect URIs and CSS theming parameters.
2. What happens if we exceed monthly booking limits? Usage beyond plan thresholds incurs overage fees calculated per additional booking/calendar connection, with detailed breakdowns available in the dashboard. Enterprise contracts can negotiate custom thresholds and billing alerts, while Growth-tier users receive automatic email notifications at 80%/95% utilization.
3. Can we migrate existing calendar integrations to Recal.dev? The API supports bulk import of existing Google/Outlook events through CSV/JSON mappings and provides migration tools to map legacy event IDs to Recal's unified format. Dedicated support engineers assist with complex transitions during onboarding periods.
