The free OAuth redirect check I wish I had before another deploy

I opened the free preview for OAuth Redirect Doctor today because I kept seeing the same loop: people fix the provider dashboard, redeploy, and still get bounced by one stale host or callback path.

When I debug these, I paste the exact reset link or redirect_uri first, then line up the app URL, auth base URL, callback path, and any explicit redirectTo in code. tbh that catches most of the "it works locally" bugs before I waste another hour rotating secrets.

If you're stuck in that loop, the free preview is here: https://oauth-redirect-doctor.vercel.app?utm_source=ih&utm_medium=post&utm_campaign=ih-roundup-2026-06-07
