  • Tampermonkey

    Userscript manager for running custom scripts on websites.

    FreeProprietaryBrowser extension

    Tampermonkey runs the same scripts across every major browser and adds script updates, backups and a built-in editor, but it is closed source and does not manage user styles.

  • Violentmonkey

    Open-source userscript manager with cloud backup.

    Violentmonkey is an open-source userscript manager under the MIT license with script sync through your own storage, but its listing does not mention Safari or iOS support.

  • ScriptCat

    A userscript manager extension compatible with Tampermonkey scripts that can also run background scripts.

    FreeOpen sourceBrowser extension

    ScriptCat runs existing Tampermonkey scripts and adds background scripts and extra APIs, though those extended APIs work only in ScriptCat and Safari support is not mentioned.

  • Greasemonkey

    A Firefox extension that runs user scripts to change how web pages look and behave.

    FreeOpen sourceBrowser extension

    Greasemonkey is an open-source userscript manager with a built-in editor and automatic updates, but it runs only in Firefox and receives releases infrequently.
