What is Recal.dev?
Recal is the developer-first platform designed to streamline the creation of intelligent calendar applications and robust scheduling systems. It tackles the inherent complexities of integrating diverse calendar providers (like Google and Microsoft Outlook) by offering a unified API and SDK, allowing developers to ship powerful scheduling features in a fraction of the time. Recal is built for developers creating everything from AI-driven automations and booking platforms to sophisticated enterprise scheduling solutions.
Key Features
🗓️ Unified Calendar API: Integrate Google, Outlook, and other calendar providers through a single, consistent API. This abstracts away the intricacies of each provider, simplifying event creation, management, and availability checks across all connected calendars.
⚡ Simplified OAuth & Integration: Recal handles all OAuth complexity, refresh tokens, and secure credential storage. Developers can offer users a one-click connection experience, significantly reducing integration effort and security overhead.
🤖 Multi-Calendar Protocol (MCP) for LLMs: Empower large language models (LLMs) to natively interact with calendars. MCP enables AI agents to check availability, book meetings, and manage schedules through simple tool calls, eliminating the need for custom code.
🔍 Intelligent Free Slot Retrieval: Precisely identify optimal time slots for scheduling across multiple users and calendars. Configure parameters like padding, slot duration, and earliest/latest times, all with built-in timezone awareness for global coordination.
⚙️ Developer-Centric & Fully Customizable: Recal provides a robust REST API, Node.js SDK, and interactive documentation, all without imposing any UI. This open design allows you to seamlessly integrate scheduling logic into any application, framework, or language, maintaining complete control over the user experience.
Use Cases
Enhance Online Booking Services: For beauty marketplaces, coaching apps, or online booking platforms, Recal enables you to quickly integrate comprehensive scheduling, allowing users to book appointments and manage availabilities across multiple providers effortlessly.
Power AI-Native Scheduling Agents: Integrate Recal with voice assistants, sales bots, or customer service agents. Your AI can then intelligently check calendars, propose meeting times, and book appointments directly, providing a seamless and automated user experience.
Streamline Enterprise & HR Scheduling: Simplify complex multi-party interview coordination for ATS systems, staffing agencies, and HR tech companies. Recal's unified approach helps find optimal times for candidates and hiring teams, reducing scheduling friction and accelerating processes.
Unique Advantages
Recal stands out by addressing common developer pain points with focused solutions:
Skip Months of Integration Work: Instead of building and maintaining separate integrations for each calendar provider, Recal’s unified API allows you to ship advanced calendar and scheduling features in seconds, not months. This accelerates development cycles and reduces ongoing maintenance.
No Vendor Lock-In: You retain full control over your data. Recal ensures you can always access your tokens and switch providers easily, offering unparalleled flexibility and protecting your application from vendor dependencies.

Leveraging edge computing ensures low-latency global access, providing a responsive experience for users worldwide.
