OpenSuite

OpenSuite is a collection of free, browser-based productivity tools built with pure vanilla JavaScript. No frameworks, no sign-up required -- just open it in your browser and start working.

OpenSuite is designed with simplicity in mind. Everyone should have access to free, easy-to-use productivity software -- no accounts, no subscriptions, no complicated setup. You can run it locally or use the hosted version, and you can still share your spreadsheets, documents, and presentations with anyone by simply sharing a link.

How Sharing Works

All OpenSuite apps let you share your work by encoding the entire document into the URL as a compressed base64 string. When you click Save & Share, your spreadsheet, document, or presentation is serialized to JSON, compressed, and stored in the URL hash fragment. The resulting link contains all the data -- no server needed. Anyone with the link can open it and see your work immediately.

This means that even when running OpenSuite locally (self-hosted or on localhost), you can still share your sheets, documents, and presentations with others. The data is embedded directly in the URL, so it works regardless of where the app is hosted.

Your data lives in your browser and your share links

OpenSuite stores your work in your browser's localStorage. There is no server-side database -- if you clear your browser data, switch browsers, or use a private/incognito window, your local data will be gone permanently.

Always save your work using the Share Link (File > Save & Share). The share link contains your complete document as a base64-encoded string in the URL. As long as you keep that link, you can always restore your work by opening it. Treat the share link as your save file.

If you lose both your browser storage and your share link, your data cannot be recovered. For persistent cloud storage, consider connecting to Supabase.

Shared Features

All apps share these capabilities:

  • Storage & Sharing -- save to browser storage, share via URL, or connect to Supabase for cloud persistence
  • Themes -- light and dark mode support
  • No Server Required -- all data stays in your browser
  • Share via URL -- compress your data into a shareable link (base64-encoded)
  • Works Offline -- once loaded, works without an internet connection
  • Run Locally -- self-host with Docker or any static file server and still share your work via links
