    @christopherplus get_option is a WordPress core function that takes a parameter (the option value). The documentation linked indicates that the return value of the get_option can be anything as it’s context-specific (see Are you saying that when this plugin is installed get_option() (no option name passed) returns true when it should return "1" or is there a specific option related to the WP Redis plugin that is returning a value that is unexpected (and if so, what option name are you requesting)? Or are you saying that all options that are true/false are returning boolean values when they should return strings when the plugin is installed (but not when it is not)?

    I’m unable to reproduce this issue.

    To attempt to reproduce, I installed WP Redis and then created a new mu-plugin that included an options page. On the options page, I had a radio button that included options for true, false, '1', '0', 'true', 'false', 1, 0. I then added a pre_update_option_{option-name} hook that explicitly saved whatever was stored in my option as a boolean value in a different option.

    WordPress did not distinguish between true, false, 1, 0, '1' or '0'. 'true' and 'false' were correctly interpreted as strings and therefore true when cast as boolean values no matter which was selected.

    Whether the plugin was active or not, the results I got always cast a truthy value as '1' and a falsey value as '' (when I explicitly converted to boolean) or '0' (when I pulled from the stored option).

    Tested on PHP versions 7.4, 8.0 and 8.2.

    If anyone sees this and has the same issue, please update this report with specific information about your environment, options you are saving, plugins you have installed, etc. so we can dig further into this.
