Show HN: Savior – Prevent silent form data loss in the browser (opens in new tab)

Hi HN,

I built Savior, a tiny, dependency-free JavaScript library that autosaves form input and restores it after refreshes, tab closes, or browser crashes.

It’s fully client-side, framework-agnostic, and designed to handle real-world edge cases like dynamic fields, corrupted storage, and failed submits without crashing the app.

Savior restores drafts verbatim — no judgment, no “smart” recovery — just predictable behavior.
