Format JSON, validate regex, generate passwords, calculate mortgages — and more. No sign-up, no tracking, no accounts. Everything runs in your browser.
SnapUtils brings together 10 free online developer and utility tools in one place — no sign-up, no tracking, no account required. All tools run entirely in your browser, meaning your data never leaves your device. Whether you need to format messy JSON, test a regex pattern, or calculate compound interest, SnapUtils has a clean, focused tool for the job.
Each utility is built as a standalone web app with a single purpose: do one thing extremely well. Developer tools like the JSON formatter and code formatter support multiple languages and output formats. Security tools like the password generator use cryptographically secure randomness. Finance tools like the mortgage calculator include interactive charts and amortization tables. Media tools like the QR code generator and image reverse search handle uploads, drag-and-drop, and clipboard paste.
