How to choose infrastructure as code

Choosing infrastructure as code comes down to a few decisions that matter more than a long feature checklist:

Pricing model & free tier. 4 of these tools offer a free tier, so you can trial the workflow before paying. Watch for per-seat minimums and add-on fees.
Core features vs. your job-to-be-done. Write down the specific outcome you need and shortlist on must-haves only — extra features you won't use rarely justify a higher tier.
Integrations. The best infrastructure as code fits the stack you already run. Check for native integrations with your other tools, or an API/Zapier path.
Ease of use & onboarding. Run a real trial with your own data and the people who'll use it daily. A tool that wins on paper can still lose on usability.
Support & scalability. Confirm the plan you're buying includes the support level and limits you'll need as you grow.
