Defer

Defer, headquartered in Paris, Île-de-France, France, operates within the B2B sector, specifically focusing on engineering, product, and design. As a participant in the Y-Combinator W23 batch, the company has developed a platform that enables developers to define CRON jobs directly using ‘defer.cron()’ and manage long-running tasks with customizable time limits starting at 30 minutes. The platform supports precise control over concurrency at the function level and ensures that jobs are executed in the order they were enqueued. It also features a full history of executions, including arguments, results, and final states, and allows for job payloads up to 16Mb. Defer offers elastic scaling and fault tolerance with a distributed scheduling cluster, enabling the handling of millions of jobs without the need for extensive storage management. Additionally, the platform provides control over RAM and CPU resources at the function level, supports concurrent job execution for enhanced performance, and includes a persisted queue to ensure no execution is lost. Aimed at Node.js developers, Defer helps in optimizing web application performance through a simple, well-documented API and a managed platform complete with an operational dashboard. The company’s vision is to become a cross-language reference for background processing solutions and currently serves regions including France and Europe. Since its launch, Defer has attracted over 250 users, including 5 paying customers, and has been featured in the two largest Node.js newsletters.
