a Zero Infrastructure Node.js background jobs platform.<br> I've been previously working at Algolia and doing open-source with <a href="https://dev.to/the-guild">The Guild</a>.</p> <p>As all of you, Bryan - my cofounder, and I experienced over the years how modern web apps must be performant while being integrated with many 3rd party APIs.<br> Such requirements make <strong>background jobs an essential</strong> part of modern Node.js technical stacks.<br> <br><br> Still, while the <strong>Node.js developer experience improved in recent years</strong><br> (<em>building and deploying Serverless applications with Vercel, scaling your database with Supabase, or setup a robust logs stack with Logtail</em>), <strong>the experience remained the same around background jobs</strong>.</p> <p>Today, working with background jobs requires developers to do some <strong>infrastructure work</strong> (either on AWS SQS or at least set up a Redis and workers) <br> and deal with queueing libraries that come with a dedicated <strong>mental model to learn and boilerplate code</strong> to write.</p> <p>Finally, operating background jobs in production, at scale, often require more infrastructure work and <strong>building internal dashboards</strong><br> to better support customers (<em>ex: "Find jobs that failed for user#1234" is a tricky task with existing queueing dashboard</em>).</p> <p>We believe that <strong>background jobs play an important part</strong> - as important as running API close to end-users (on edge) - to build swift user experiences.<br> For this reason, working with background jobs should be as simple as building Serverless apps with Vercel<br> or scaling a database with Supabase.<br> <br><br> Defer fill that gap by bringing a <strong>zero infrastructure</strong> approach and <strong>full-featured API and dashboard</strong> with<br> configurable retries, throttling, concurrency, support for multiple environments, alerting, and more.</p> <p>We hope Defer will enable <strong>all JavaScript and TypeScript developers</strong> (front-end and back-end developers) to <strong>build powerful applications faster</strong>.</p>
