Why We Run Almost Everything on Cloudflare Workers

When starting a new project, one of the first decisions is where the application will run.

Over the last few years, we’ve increasingly chosen Cloudflare Workers for APIs, backend services, webhooks, and even full-stack applications. It’s not because they’re trendy it’s because they solve many of the problems we encounter in production.

That doesn’t mean Workers are the right choice for every project, but for most of what we build, they’ve become the default.

1. Fast by Design

Cloudflare Workers run on Cloudflare’s global edge network, which means requests are processed closer to users.

Instead of routing traffic to a single server, applications can respond from locations around the world, reducing latency and improving the overall user experience.

For applications with users across multiple regions, this makes a noticeable difference.

2. Infrastructure Becomes Simpler

Managing virtual machines, configuring servers, and handling scaling can quickly become operational overhead.

With Workers, there’s no server to maintain. Deployments are straightforward, scaling happens automatically, and the focus stays on building features instead of managing infrastructure.

Less operational work means faster development.

3. Great for APIs and Event-Driven Workloads

Many modern applications rely on lightweight APIs, webhooks, scheduled jobs, and third-party integrations.

These workloads are exactly where Workers perform well. They start quickly, handle concurrent requests efficiently, and integrate well with services like KV, Durable Objects, R2, and D1 when persistent storage is needed.

4. Deployment Is Fast

Deployments take seconds, making it easy to ship updates frequently.

Quick deployments encourage smaller releases, faster iterations, and simpler rollbacks when something doesn’t go as planned.

For development teams, this short feedback loop is invaluable.

5. It’s Not the Answer to Everything

Cloudflare Workers aren’t a universal solution.

Applications with long-running background processes, heavy compute workloads, or specialized infrastructure requirements may be better served elsewhere.

Choosing the right platform always depends on the problem you’re solving.

Final Thoughts

We don’t use Cloudflare Workers because they’re the newest option we use them because they help us ship reliable software faster.

For the types of applications we build, they offer a great balance of performance, scalability, and operational simplicity. And while every project has different requirements, Workers have proven to be a solid foundation for most of our backend services.

Good engineering isn’t about using the latest technology. It’s about choosing tools that solve real problems with the least amount of complexity.
