Tester
Semver Range Tester
Check whether a semantic version satisfies an exact, caret, tilde, or comparison range.
Use this tool when
These are the practical situations where this workflow usually earns its keep.
You need to verify whether a version satisfies the intended range rule.
You want a browser-local pass before documenting or applying the correct package constraint.
You need a smaller, cleaner review surface during dependency review and release triage.
Daily workflow acceleration
Semver Range Tester helps when teams need to verify whether a version satisfies the intended range rule without opening a heavier system or rebuilding the same transformation manually every time.
Review and handoff clarity
A focused output is useful when the next step is documenting or applying the correct package constraint and the current raw input would otherwise slow down the reviewer or teammate.
Lower-friction local handling
For dependency review and release triage, keeping the task in the browser is helpful because the source material often does not need to leave the user’s machine just to answer this one question.
Common mistakes to avoid
These are the checks that usually keep the output useful instead of misleading.
A satisfying version range is only one part of upgrade risk; behavior and transitive dependencies still matter.
Testing only examples that should pass and forgetting counterexamples.
Moving a rule into code before checking whitespace, casing, empty input, and unusually long values.
