Chess.com does not offer free cloud analysis, only local line evaluations. The first is a lot easier to understand for beginners and much more accesible to users with lower end devices. Lichess cloud analysis is a wonderful tool, and users who might not want to leave chess.com (because of their friends or arguably better puzzles and lessons) can get a glimpse of its advantages.\n\n## Installation\nThis is a Chromiun-based extension, so you can use it on Chrome, Edge, Opera, Firefox, or other (non-tested) web explorers. Find it either on the Firefox Addons website or the Chrome Webstore.\n\n**Chrome Webstore**  \n[Link!](https://chrome.google.com/webstore/detail/lichess-cloud-analysis-fo/ngepiabohcfcoggpfghnfoefpnmnfocd)\n\n**Firefox Addons**  \nPending review.\n\n**Manual installation**  \nDepending on your browser and your OS, you have two options.\n1. (Any OS): Download and unzip source code, go to [chrome://extensions/](chrome://extensions/) or your browser's equivalent, turn on developer mode, click on \"load unpacked\", and go to the directory of the source code.\n2. (Easier, but only MacOS/Linux) Drag the latest .crx file from [release](https://github.com/califernication/lichessAnalysis/releases) from this repo and drop it in [chrome://extensions/](chrome://extensions/) or your web explorer's equivalent (make sure developer mode is enabled!).\n\n## How to use?\nAfter you have finished a game on chess.com or when you go to review a game, the script injects an HTML button under the nominal Analysis button. When clicked, it takes you to a Lichess analysis board of the same game.\n\n![You'll see a nice new button like below](https://github.com/califernication/lichessAnalysis/blob/main/screenshots/newButtonGif.gif)\n\n## FAQ\n\n**Is there a game import limit?**  \nYes, Lichess limits import to 100 games per hour when not authenticated (OAuth2). The extension currently does not ask the user to authenticate in order to lessen set up time.\n\n**How does the extension work?**  \nThe script scraps your game's PNG from chess.com through the DOM and then sends a POST request to the Lichess API through the api/import endroute. Chess.com's official API is _very_ limited, so getting information from the DOM directly is necessary; currently, there is no way to get a game's PGN through the API. If this ever changes, I will update the source code and the documentation to implement this better practice.\n\nThe extension uses [Arrive.js](https://github.com/uzairfarooq/arrive), which abstracts the interface of [mutation observers](https://developer.mozilla.org/en-US/docs/Web/API/MutationObserver), to interact with the DOM efficiently.\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcalifernication%2Flichessanalysis","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fcalifernication%2Flichessanalysis","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcalifernication%2Flichessanalysis/lists"}
