Why Your Team Deserves Better Than Jenkins and GitHub Actions

Why Your Team Deserves Better Than Jenkins and GitHub Actions

Your CI/CD pipeline shouldn’t be the thing that slows down your deployments. Yet if you’re running Jenkins, you’ve probably spent more time debugging your build infrastructure than you’d like to admit. And if you’re on GitHub Actions, you’ve learned the hard way that “shared runners” means “shared headaches” when your builds queue up behind everyone else’s crypto mining operations.

We built CentralCI because we got tired of these problems too.

The Problem with Shared Infrastructure

GitHub Actions runs your builds on shared infrastructure. That sounds cost-effective until you’re stuck waiting 15 minutes for a runner to become available, or your build times mysteriously balloon because someone else’s workload is hammering the same physical hardware. You can’t see it, you can’t control it, and you definitely can’t fix it.

This isn’t just annoying—it’s expensive. When your deployment pipeline takes 45 minutes instead of 15, that’s not just lost productivity. That’s your team context-switching to other work, losing flow state, and ultimately shipping slower. For a team of 10 developers, that’s potentially thousands of dollars in lost time every week.

The Problem with Jenkins

Jenkins works, in the sense that it technically executes builds. But if you’re honest about it, Jenkins is that old server in the corner that everyone’s afraid to touch. Plugins break between versions. Groovy scripts are a mess to debug. The UI looks like it’s from 2008 because it is. And good luck explaining to your new hire why they need to learn Jenkins-specific concepts that won’t transfer anywhere else.

More critically, Jenkins doesn’t scale predictably. Adding capacity means provisioning more infrastructure, configuring more agents, and hoping your master node doesn’t become the bottleneck. When things go wrong—and they will—you’re the one who gets paged at 2am to figure out why the build queue is backed up.

What CentralCI Does Differently

CentralCI gives you a dedicated, fully managed Concourse cluster. Not shared. Not multi-tenant where it matters. Your cluster, your VPC, your predictable performance.

Every cluster runs on AWS with a dedicated Postgres instance from Neon.tech. We handle the infrastructure, monitoring via Datadog, security through CloudFlare, and all the operational overhead. You get GitHub OAuth for authentication and a clean, modern interface that your team will actually want to use.

But the real advantage is Concourse itself. Where Jenkins gives you plugins and GitHub Actions gives you YAML spaghetti, Concourse gives you three primitives: resources, tasks, and jobs. That’s it. Everything else composes from there. Your pipelines are code. They’re versioned. They’re testable. And most importantly, they’re reproducible—every task runs in a fresh container with explicit dependencies, so you never get the “works on my machine” problem in your CI environment.

Performance You Can Actually Measure

We’re serious about performance. Our infrastructure runs Amazon Linux 2023 on Kernel 6.12+, tuned for container workloads with optimized sysctl settings for network throughput and connection handling. We monitor everything through Datadog with dozens of Concourse-specific metrics—build durations, queue depths, worker utilization, database connection pools, garbage collection performance.

When Comcast runs 60,000 builds per day across their Concourse clusters, they use statistical methods like Z-scores to track performance degradation at scale. We apply the same rigor to our platform. If your builds start running slower, we know about it before you do.

This matters because predictable performance lets you make predictable commitments. When your team says “this deploys in 20 minutes,” it actually deploys in 20 minutes. Not 20 minutes plus however long GitHub Actions feels like making you wait today.

Built for Compliance, Designed for Speed

If you’re in a regulated industry, you already know that compliance requirements and fast deployments usually pull in opposite directions. CentralCI handles this through Concourse’s native security model: every task runs in isolation, all credentials go through a credential manager (we support Vault, AWS Secrets Manager, and others), and the entire pipeline is auditable because it’s declarative code.

Your cluster runs in a dedicated VPC with CloudFlare Tunnel handling ingress security. We can deploy entirely within your compliance boundary if needed. And because Concourse is open source, you’re not dependent on a vendor’s security-through-obscurity approach—everything is inspectable, auditable, and documented.

Real Engineering, Zero Operations

Here’s what we’ve contributed upstream to Concourse just in the last few months: performance improvements to HTTP compression that speed up every web request, memory metrics that help operators tune their clusters, security fixes for HTML injection vulnerabilities, and database driver updates that improve connection pooling under load.

We do this because we run production Concourse clusters for real teams. When we find something that needs improvement, we fix it upstream so everyone benefits—including you. This isn’t a hobby project or a side business. This is infrastructure we bet our own reputation on.

Your subscription includes everything: infrastructure, monitoring, security, updates, and support from people who actually know how Concourse works under the hood. No separate bills for runners, bandwidth, or storage. No surprise charges because your team ran more builds than expected. Just predictable monthly pricing based on your cluster size.

Why This Matters for Your Team

Your CI/CD pipeline is critical infrastructure. It’s the difference between deploying 10 times a day and deploying twice a week. It’s the difference between catching bugs in 5 minutes and catching them in 5 hours. And it’s the difference between your senior engineers focusing on product work versus debugging Jenkins plugins.

CentralCI gives you enterprise-grade infrastructure without enterprise-grade operational overhead. You get the performance and reliability of a dedicated system with the simplicity of a managed service. No pager duty for your build system. No capacity planning meetings. No emergency patches because a Jenkins plugin broke in production.

Just fast, predictable, reliable builds that let your team ship software.
