  2. Create, upload, and search for PGP keys.
  3. Easy to understand language. You want to read, write, or attach a file?
  4. Mobile friendly (Progressive web app). Can be saved to home screen. Tested on Android and iOS.

Changelog link


You can run MagicPad four ways:

  1. Download executable at
  2. Clone and run ./app/index.html via web browser
  3. Clone, build and run executable (saved at ./dist):
npm install
npm run dist

To only build html/css/js without running electron, run: npm run buildwebapp If building from Ubuntu, run this first:

sudo apt-get install rpm
  1. Run Electron via Node from command line (you need Electron globally installed):
npm i -g magicpad
npm i -g electron

Build explained

In the build procedure, the following happens:

  1. HTML files in the ./html_src folder are combined into a single index.html file in ./app.
  2. JS files in ./app/js are added as <script> tags after </body> tag in index.html. (Step 1 and 2 are controlled by ./build_magicpad.index.js)
  3. index.html is saved to ./app.
  4. All other files are static in ./app and are not altered.
  5. Electron executable is created in a ./dist folder.

Authoring executables

  1. You need all of the Apple Developer certificates from the Apple Developer Program.
  2. Create a Mac App provision profile in the Apple Developer website, download it, and name it as embedded.provisionprofile and place it in root.
  3. Edit your ~/.bash_profile.rc i.e. nano ~/.bash_profile.rc to include these parameters:
export CSC_KEYCHAIN=login
export appleId=YOUR_APPLE_ID

then run source ~/.bash_profile to refresh. 4. Go to ./src/mac_build/entitlements.mas.plist and replace application name to yours from Apple Developer website. You may have to replace the application name in package.json as well as the appId variable in notarize.js. 5. There is a bug in electron-osx-sign module and you need to go to ./node_modules/electron-osx-sign/sign.js then comment out this block:

if (opts.platform === 'darwin' && opts['gatekeeper-assess'] !== false) {
  promise = promise
    .then(function () {
      debuglog('Verifying Gatekeeper acceptance for darwin platform...')
      return execFileAsync('spctl', [
        '--type', 'execute',
