Choose Fly.io if:
Teams with users spread across continents who care about latency.
Choose Jenkins if:
Teams with infrastructure skills who need full control or cannot send code to a hosted service.
Fly.io: pros & cons
- Genuinely easy multi-region deployment
- Runs full containers, not a restricted runtime
- Good fit for latency-sensitive workloads
- Multi-region data is still your problem to solve
- Operational rough edges reported by users
- Pricing needs attention once you add regions
Jenkins: pros & cons
- Free and open source with no usage limits
- Enormous plugin ecosystem
- Runs entirely on your own infrastructure
- You maintain the server, the agents and the plugins
- Interface and defaults feel dated
- Plugin quality varies and updates can break builds
Our verdict on Fly.io
Compelling when latency actually matters. Single-region apps get little benefit from the added complexity.
Our verdict on Jenkins
Still the right answer when control matters more than convenience. For most small teams a hosted CI is less work.
