Perapera versus GitHub
Compare	Perapera	GitHub
Verdict	Depends	Worth it
Best for	Casual Chinese/Japanese web readers	Software teams of any size
Who it's not for	Firefox users . official support is gone	Non-technical teams that never touch code
Privacy	No known public vulnerabilities found in the sources reviewed.	Strong built-in security tooling, but a May 2026 breach via a malicious VS Code extension and earlier incidents are documented.
Support quality	Firefox dropped; project abandoned per users	No support-quality evidence in sources
Public sentiment	Learners loved this free popup dictionary for Chinese reading but widely report it is now unmaintained, especially on Firefox.^⁴	Users treat GitHub as the developer standard, but many beginners find Git confusing and Copilot's new usage-based pricing is widely unpopular.¹⁴
Biggest gotcha	Firefox support ended; extension no longer updated there^¹	Copilot AI credits are usage-based; users report surprise bills and lock-in. Model costs before enabling org-wide.
