Offline Zip Browser

This project is meant so that I can play interactive fiction games, but it's also good for any similar project. You can even play my LizardUp game if you download the source as a zip and open it.

Use

  1. Use "Open with..." from your file app on a .zip file or standalone .html file, and select "Offline Zip Browser".
  2. Enter a name for it (you cannot change this yet)
    • The app will attempt to guess if .zip or .html but may get it wrong so it's good to specify .zip or .html in the name too.
  3. The file will be saved to app's storage and now any time you open the app you will have access to this file. LocalStorage will persist across sessions. Which means most interactive fiction games with save states will work.

Note: if you use termux + curl to download files, you will have to set the allow-external-apps property must be set to true in ~/.termux/termux.properties in termux.

Manifests

Create a ozb_manifest.json file in your zipped html app next to your index.html with a variety of useful settings that will control how the app is loaded. Generally these properties will help misbehaving applications work better.

Theoretically I'd like to be able to clear cache for a site on startup, but it's not built into web views by default that I can tell.

dateToSpoof

Offset based timestamp, loaded with OffsetDateTime.parse. Values like "2025-01-30T19:00:00-05:00" will work.

useUnsafeURL

Set the base url of the app to a "real" url. The app will still try to prevent access to the wider web.

Deep Links

Deep links to link into the app. Because the app is intentionally not communicating with servers or other apps, deep links do not work inside the app, so you can only link in from another app.

Debug builds of the app use a different deep link hostname (add .debug to the end of the hostname)

  • Delete a file
  • Rename a file
  • Deep link to play a game app://foss.zip.offline.browser.offlinezipbrowser/play/Your_game_here.html

RENAME_FILE

rename a file

DELETE_FILE

delete a file

TODO

  • Clear Cache options
  • Have multiple instances of the app open at once

About

Browse a zip file containing an index.html file as if it was a website. Cache/JS enabled, but it's all offline.

Offline Zip Browser
This project is meant so that I can play interactive fiction games, but it's also good for any similar project. You can even play my LizardUp game if you download the source as a zip and open it.
Use
  1. Use "Open with..." from your file app on a .zip file or standalone .html file, and select "Offline Zip Browser".
  2. Enter a name for it (you cannot change this yet)

    • The app will attempt to guess if .zip or .html but may get it wrong
so it's good to specify .zip or .html in the name too.
  3. The file will be saved to app's storage and now any time you open the app
you will have access to this file. LocalStorage will persist across sessions.
Which means most interactive fiction games with save states will work.
Note: if you use termux + curl to download files, you will have to set the
allow-external-apps property must be set to true in ~/.termux/termux.properties in termux.
Manifests
Create a ozb_manifest.json file in your zipped html app next to your index.html with a variety of useful settings that will control how the app is loaded. Generally these properties will help misbehaving applications work better.
Theoretically I'd like to be able to clear cache for a site on startup, but it's not built into web views by default that I can tell.
dateToSpoof
Offset based timestamp, loaded with OffsetDateTime.parse.
Values like "2025-01-30T19:00:00-05:00" will work.
useUnsafeURL
Set the base url of the app to a "real" url. The app will still try to prevent access to the wider web.
Deep Links
Deep links to link into the app. Because the app is intentionally not communicating with servers or other apps, deep links do not work inside the app, so you can only link in from another app.
Debug builds of the app use a different deep link hostname (add .debug to the end of the hostname)
  • Delete a file
  • Rename a file
  • Deep link to play a game app://foss.zip.offline.browser.offlinezipbrowser/play/Your_game_here.html
RENAME_FILE
rename a file
DELETE_FILE
delete a file
TODO
  • Clear Cache options
  • Have multiple instances of the app open at once
About
Browse a zip file containing an index.html file as if it was a website. Cache/JS enabled, but it's all offline.
