Small utilities you would otherwise reach for a terminal to do: pretty-print and validate JSON with precise error positions, or generate MD5, SHA-1, SHA-256 and SHA-512 hashes for checksums and cache keys. No install, no account — open the page, paste, and get the result. Because hashing and formatting run client-side, source code and payloads never touch a server.
