About Çevrimiçi araçlar
www.518882.com is a local-first toolbox on Cloudflare Pages: text, Chinese, developer and file utilities run in your browser. No third-party content-processing APIs; inputs are not uploaded to our servers for computation.
E-E-A-T: libraries (OpenCC, pinyin, Prettier, jsonpath-plus, bcryptjs, etc.) are self-hosted on this origin. No accounts; theme/favorites stay in localStorage. See dateModified on tool pages.
We will not fetch or audit arbitrary URLs you paste, run HTTP/WebSocket testers against third hosts, or send your secrets to external APIs.
Good for private text, configs, CSP/robots/llms.txt/JSON-LD drafts and light image work—not cloud collaboration archives or server pipelines.
