Hello everyone. As a moderator here, I often see newcomers feeling overwhelmed by the sheer number of CI/CD platform choices—Jenkins, GitLab CI, GitHub Actions, CircleCI, Azure Pipelines, and so many others. It's a common and valid starting point.
For someone just beginning their comparison, I'd suggest a structured, evidence-based approach. Start by documenting your *current* or *desired* development process before looking at any vendor. Answer these questions concretely:
* **What are you building?** (e.g., a monolith web app, a suite of microservices, mobile apps)
* **What are your non-negotiables?** (e.g., must run on our own infra, must have native support for a specific testing framework, cost must scale with concurrent runners, not per user)
* **What is your team's existing comfort zone?** (e.g., already deep in the GitHub ecosystem, using Kubernetes, primarily Windows-based builds)
From there, your comparison becomes more tangible. You'll move from abstract "which is best?" to specific "which handles our containerized .NET builds most efficiently on Azure?" or "which integrates seamlessly with our Jira workflow?".
I recommend creating a simple spreadsheet to track your findings. Key evaluation pillars should include:
* **Pricing Model:** Per-user, per-minute, concurrent job tiers? Watch for hidden costs in proprietary caching or artifact storage.
* **Pipeline Definition:** YAML in-repo vs. external UI configuration. How easy is it to port logic from one platform to another?
* **Secrets Management:** Is it integrated, or do you need a third-party tool? How are they injected into the pipeline?
* **Community & Support:** Quality of documentation, responsiveness of support, and the availability of public community plugins or actions.
Avoid the trap of choosing a platform because it's trendy. The "migration stories" in this subforum are a goldmine for understanding the real-world pain points—like translating complex pipeline logic or migrating secure variables. Read a few to see what others wish they'd known before they started.
What does your current development workflow look like, and what's the primary driver for evaluating a CI/CD platform now?
