Choosing well
Can it create previews for pull requests?
Compare support for pull request previews if you want changes available for review before they reach production.
Check the Git providers the tool supports alongside its pull request preview feature.
How much control do I need over preview lifecycles?
Look for preview lifecycle and expiry controls that fit how long you need an environment to stay available.
Expiry settings can help manage temporary environments; check the tool's details to see what controls it offers.
Does it need to create database previews?
If a review environment needs a database, compare database preview support before choosing a tool.
Can I use custom domains for previews?
Check custom domain support if reviewers or teammates need to reach previews at a domain you choose.
Which platforms and pricing options should I check?
Compare web, API, Linux, self-hosted, macOS and Windows availability with the way you plan to deploy or manage previews. Platform details do not confirm Android app support, so verify that separately if you need it.
Check the free plan and paid starting price, and whether a trial is offered. For example, Railway lists a free plan, a $5-per-month starting price and a 30-day trial; Skyhook lists a free plan.
