Review summary

CheerpJ Applet Runner is appreciated for enabling old Java applets to run on modern browsers like Edge, serving as an effective alternative to Internet Explorer mode and avoiding local Java installation. However, users frequently report it fails to launch applets consistently, struggles with page hangs, and requires manual activation for each page, which reduces convenience. Additionally, encoding issues and restricted permission settings were noted. Overall, it is a valuable tool with room for improvement in reliability and usability.
Pros
  • Allows running old Java applets on modern browsers like Edge and Chrome, enabling access to legacy websites.
  • Provides a solution to run Java applets without requiring Java installation on the host system, utilizing WebAssembly.
  • Effectively replaces Internet Explorer compatibility mode for some government and older websites, improving stability and usability.
  • Simple and functional user interface that adds value for users needing Java applet support.
Cons
  • Recent versions sometimes fail to launch Java applets or hang, requiring page reloads.
  • Users must manually activate the add-on (click the icon) on every page, which is inconvenient and repetitive.
  • Issues with encoding support causing garbled content on web pages containing embedded Java applets.
  • Limited permission options exist but are mostly disabled, restricting usability and personalization.

2025-03-02 family This new version doesn't work anymore :(
2025-02-28 Luis Tried on 4 different old websites that needed Java to run some features and worked like a charm
2024-04-07 R Doesn't work at all. Acts like it's going to start the applet, but never actually does.

2024-01-26 Luiz Excelente... falta apenas uma forma de deixar executando? Não encontrei modo de manter ativo
2023-12-28 天祺 据说是用wasm实现了完整的Java applet api,所以你甚至不需要在主机上装java。但是目前它对编码的支持有问题,内嵌Java的网页上其他dom会在启用后变成乱码
2023-08-27 Jerry Constantly hangs, have to reload the page and applet to regain control.
2022-12-22 Bill I wish we didn't have to click on the icon for every page we open. For the life of me I cannot understand why it has other options in the "Can open and change (etc)" yet only the "On click" can be chosen from those options. Other options are grayed out. Kind of defeats the purpose for having options in the first place. Nice to be able to view applets again, for sure, but this click stuff is a nuisance.
2022-10-13 Rashid its unable to launch java applet on my Edge. Useless add on.
