User Reviews

Users praise Better Canvas for strong customization and ease of viewing Canvas data, plus a lightweight, appealing dark mode. However, recurring issues curb its reliability: submission functionality can fail, GPA calculations can break, the revert option sometimes doesn’t work, theme opt-in is flaky, and it can affect other sites’ behavior. Overall, it’s powerful and visually pleasing but has stability issues in several core areas.
Pros
  • Powerful customization and theming options that let you personalize course cards and dashboards with many visual themes.
  • Significantly improves Canvas usability by making due dates, assignments, and grades easier to view at a glance.
  • Dark mode is lightweight and generally artifact-free with low CPU overhead.
  • Overall ease of use and quick setup, with visually appealing results.
Cons
  • Core features can be unreliable, such as the ability to submit assignments.
  • GPA/grade calculations can fail (NaN) or fail to import course data.
  • Revert button sometimes does nothing.
  • User-generated themes opt-in can be broken, showing only one theme per page instead of many.
  • Interferes with other sites (e.g., animations misbehave) or requires manual on/off to avoid site-wide issues.

my favorite extension ever. Been using it for years now and it's never failed me. So so so many cool themes made by other users and making a theme is easy. Somehow has genuinely made being on canvas and getting work done way easier when the theme is fun or interesting to me. A ton of thanks and good wishes for the person who made this thing! Thank you!

Is Better Canvas Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Better Canvas requires a few sensitive permissions. Exercise caution before installing.
