Users who get problems wrong on BOJ can use this extension to find counterexamples that expose bugs in their solutions, helping them debug and improve their code.

1. User visits a BOJ problem page (acmicpc.net/problem/{id}). 2. Content script extracts the problem ID and sends it to the background worker. 3. Background worker fetches a batch of problem IDs from https://testcase.ac/api/extension/problems to check which have counterexamples. 4. If the current problem has a counterexample, the extension shows a badge and opens a popup. 5. On problem list pages, the extension marks problems that have available counterexamples with an icon linking to testcase.ac.

目标用户: BOJ (Baekjoon Online Judge) users, competitive programmers, students solving algorithm problems

The popup chunk (chunks/popup-Cx_znDKv.js) is heavily minified React code (~145KB), making it difficult to fully analyze the popup UI logic. However, no login or payment-related code was found in grep searches.
The extension communicates with https://testcase.ac which may have its own login/paid system, but the extension itself does not gate features or require authentication.
The extension is in version 0.3.1, suggesting it is still in early development; future versions may add login or paid features.

付费分析

未识别到付费功能

No payment, subscription, premium, upgrade, billing, or license-gating code found in the extension. The extension calls a free API endpoint without any authentication or plan checks. The 'pro' and 'license' keyword matches in the static analysis are from React library source code (react.production.min.js, @license headers), not from the extension's own business logic. The extension appears to be completely free with no paid features.

登录理由: The extension does not implement any login UI, authentication flow, or credential storage. The content script on acmicpc.net and the background worker communicate with https://testcase.ac/api/extension/problems without any auth headers, tokens, or session cookies. The popup is a simple React UI with no login/sign-up screens. Users can use the extension's core functionality (finding counterexamples for BOJ problems) without creating an account or logging in.
