HTMLSync

by Tigran ·  · SaaS & Tools

Turn any single-file HTML app into a cloud-synced web app.

About

Stop losing data to one-device offline HTML apps relying on localStorage. HTMLSync hosts your single-file HTML app, captures its localStorage in the cloud, and keeps it in sync across every device you open it on.

  1. Upload your HTML file—no edits needed.

  2. Get subdomain {slug}-{username}.htmlsync.io with built-in database & auth.htmlsync.io

  3. Share read-only public views or hide elements via .public-hidden; exclude keys with no_sync_ prefixes.

Free plan: 3 apps, 10 MB each. Paid tiers scale to 100+ apps and custom domains. Launching today for indie hackers, makers and AI-generated-app lovers.
