  • (2022-09-15) Paul Hoover: This extension does not work. It immediately displays the following with no other information on how to resolve. "Not working? Did you..." "Use Svelte version 3.12.0 or above?" (yes, we're using 3.49.0) "Build with dev mode enabled?" (yes)
  • (2022-09-13) Михаил Серов: Doesn't work at all (

  • (2022-06-25) Satana Charuwichitratana (Mick): Not working in Chrome 103.0.5060.53 (Official Build) (x86_64)
  • (2022-06-11) vincej151: I couldn't make it work. I reloaded both svelte and the extension 3 times. If it does work you need to make it such it works out of the box. I don't want to jump through hoops of fire to make this work.
  • (2022-06-02) Amanda Patricia: I tried to get this to run several times. Hard refresh, restart machine, incognito, remove and re-install. This does not work for me. Any ideas? Env = Chrome, Mac IOS 12.4, Svelte 3.22.3.
  • (2022-05-16) Caner Yurtbay: doesnt work anymore
  • (2022-05-14) sk shahra: wow
  • (2022-04-26) Travis Ray: Doesn't work anymore on the latest version of Chrome, and when it did work - it wasn't very good.
  • (2022-04-18) oxolov: Does not work anymore
  • (2022-03-19) babakfp: It doesn't work and it seems to be abandoned.
  • (2022-01-19) Jan T. Sott: Great extension that works as expected. The only thing I'm missing is better integration into Chrome's design language. Especially the small font-size is a major difference to the rest of the interface and potentially impacts a11y (other than being a subjective annoyance).
  • (2022-01-10) Benjamin Sewards: Does not detect Svelte when the application uses Svelte via Client-side component API (https://svelte.dev/docs#run-time-client-side-component-api).
  • (2021-10-01) Hunmin Park: Nice extension for debugging Svelte application
  • (2021-08-15) Pisces J: It looks like the vue dev tools and I think it better than nothing before.
  • (2021-06-10) Thomas Orlita: It would be super awesome if it also worked in Electron DevTools. Edit: It actually works in Electron, although not directly in DevTools: https://github.com/RedHatter/svelte-devtools/issues/37#issuecomment-781622702
  • (2021-03-08) AmirHossein Ahmadi: Thank you for your efforts.
  • (2020-12-09) Jaeho Sim: 아주 좋습니다!
  • (2020-10-27) Joe Moses: In principle it works, it provides info on props and such, however the actual scope of functionality isn't too wide. The plugin struggles to detect Svelte when in embedded in another system, WP, running jQuery for example.
