Why Jenkins might cost you 10x more than Bitbucket Pipelines

This post analyzes the total cost of ownership (TCO) for self-hosted CI/CD solutions like Jenkins compared to SaaS offerings like Bitbucket Pipelines. It details the hidden costs of self-hosting, including developer productivity sacrifices due to under-provisioning, wasted compute from over-provisioning, and the significant expense of maintaining a dedicated platform engineering team for auto-scaling. The analysis quantifies these costs using a hypothetical 500-developer team, demonstrating that Bitbucket Pipelines is significantly more cost-effective due to its elastic scaling and pay-as-you-go model, which eliminates the need for internal infrastructure maintenance teams.
