The Silent Shift: Engineers Are Moving Back to Self-Hosted Tools
Why This Is Happening
1. Cost Control
Cloud services are expensive, and those costs add up fast. A self-hosted GitLab instance? Maybe $50/month for infrastructure. GitHub Enterprise? That's thousands. If your team knows what they're doing, self-hosting can save serious money.
Here's a real example: A team I know cut their CI/CD costs by 80% when they moved from cloud-hosted runners to their own infrastructure. Same workload, but $2,000/month dropped to $400/month.
2. Data Sovereignty and Privacy
With increasing regulations (GDPR, CCPA) and security concerns, many organizations want their code, data, and infrastructure under their direct control. Self-hosting gives you complete data control, no vendor lock-in, compliance with strict regulations, and custom security configurations.
3. Performance and Reliability
Self-hosted tools can actually be faster and more reliable. No network hops to external services, no sharing resources with other customers, you control everything, and you're not dependent on someone else's uptime.
I've seen self-hosted Git servers run 3x faster than cloud alternatives. Why? They're on the same network as the dev team. Simple as that.
4. Customization
Cloud services offer what they offer. Self-hosted tools can be customized to your exact needs: custom integrations, modified workflows, specific security requirements, and unique feature combinations.
Where Self-Hosting Makes Sense
Git Hosting
Self-hosted Git solutions (GitLab, Gitea, Forgejo) are mature and feature-rich. They offer full control over your code, no per-user licensing costs, custom integrations, and on-premise deployment options.
When it makes sense: Teams with 10+ developers, security requirements, or cost concerns.
CI/CD Pipelines
Self-hosted CI/CD (Jenkins, GitLab CI, Drone) gives you unlimited build minutes, custom hardware configurations, no per-minute pricing, and complete control over the build environment.
When it makes sense: High build volumes, specialized hardware needs, or cost optimization.
Monitoring and Observability
Self-hosted monitoring (Prometheus, Grafana, ELK Stack) provides no data egress costs, complete data retention control, custom alerting rules, and integration with on-premise systems.
When it makes sense: High data volumes, long retention requirements, or compliance needs.
AI and ML Workloads
Self-hosted AI infrastructure is becoming more common: local LLM inference (Ollama, vLLM), self-hosted model training, private data processing, and cost control for high-volume workloads.
When it makes sense: Privacy requirements, high inference volumes, or specialized hardware.
Where Cloud Still Wins
Cloud services still make sense for small teams without DevOps expertise, rapid prototyping and experimentation, global distribution requirements, services that require constant updates (like managed databases), and teams that want to focus on product, not infrastructure.
The Hybrid Approach
The smartest teams are using a hybrid approach:
- Cloud for: Managed services, global distribution, rapid scaling
- Self-hosted for: Core development tools, sensitive data, cost optimization
This gives you the best of both worlds: cloud convenience where it matters, self-hosted control where you need it.
Challenges of Self-Hosting
Self-hosting isn't free. It requires DevOps expertise, ongoing maintenance, security management, backup and disaster recovery, and monitoring and alerting. If you don't have these capabilities, cloud services are still the better choice.
The Trend Is Real
I'm seeing this shift across startups moving from GitHub to self-hosted GitLab to control costs, enterprises bringing tools back in-house for compliance, AI teams running local inference to avoid API costs, and DevOps teams self-hosting CI/CD to eliminate per-minute charges.
This isn't a rejection of cloud—it's a maturing of cloud strategy. Teams are learning when to use cloud services and when to self-host.
What This Means for Engineers
If you're an engineer, this trend means more opportunities (self-hosting requires expertise), better cost control (understanding when to self-host vs. cloud), more control over your development environment, and new skills in infrastructure management and DevOps practices.
The Bottom Line
This shift to self-hosted tools isn't about ditching the cloud—it's about picking the right tool for the job. Cloud services are great for a lot of things, but they're not always the answer.
Smart teams are asking the right questions:
- What does it actually cost?
- What do we actually need?
- What are we giving up?
- What makes sense for us, specifically?
The future isn't "all cloud" or "all self-hosted." It's a mix of both, chosen because it makes sense, not because someone told you to.
We're getting smarter about this. Moving past the "cloud-first" dogma and actually thinking about what works for our specific situation. That's real progress.
