alternatives →How to choose
Start with your constraint, not the feature list. If you're keeping your current platform, weight the overlays and how cleanly they integrate. If you're re-platforming anyway, a full-stack option may be worth the disruption. Match the tool's best-for size to yours — enterprise-grade tools are overkill (and overpriced) for small teams, and self-serve tools won't satisfy an enterprise's security review. The Finder does this filtering for you.
