Open Redirect Checker
Inspect redirect targets locally and flag protocol-relative, script-based, or off-allowlist destinations.
Target URL or full request URL
External redirect targets should be checked against an explicit host allowlist.
Use this tool when
These are the practical situations where this workflow usually earns its keep.
You need to inspect redirect targets for unsafe destination patterns.
You want a browser-local pass before taking the finding back to the route or validation logic that owns redirect handling.
You need a smaller, cleaner review surface during security review and auth-flow debugging.
Daily workflow acceleration
Open Redirect Checker helps when teams need to inspect redirect targets for unsafe destination patterns 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 taking the finding back to the route or validation logic that owns redirect handling and the current raw input would otherwise slow down the reviewer or teammate.
Lower-friction local handling
For security review and auth-flow debugging, 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 suspicious target pattern is a warning sign, but the full exploitability still depends on the route and trust boundary around it.
Treating a lightweight local result as equivalent to a full security assessment.
Sharing the raw input after the tool already produced a safer summary or masked version.
