Developer Tools

Everyday tools for building software

Developers reach for a handful of small utilities dozens of times a day: formatting a blob of JSON to read it, encoding a string to Base64, escaping a URL, or hashing a value. Pasting sensitive data into random online tools is risky, so the developer tools in this category run entirely in your browser, keeping your data on your machine while still being instant and free.

Reading and validating JSON

Raw JSON from an API is often minified into a single unreadable line. The JSON formatter beautifies it into a clean, indented structure, validates it so you can catch syntax errors immediately, and can minify it again when you need a compact payload. It is one of the most-used tools in any developer's kit.

Base64 and URL encoding

Base64 encoding turns binary or text data into an ASCII-safe string, which is essential for embedding data in JSON, data URLs, and many APIs. URL encoding, meanwhile, escapes special characters so links and query strings work correctly. Both tools encode and decode in either direction with a click, saving you from remembering escape rules or writing throwaway scripts.

Generating secure hashes

Hashing turns any input into a fixed-length fingerprint, used for verifying file integrity, storing passwords safely, and generating unique identifiers. The hash generator uses your browser's built-in cryptography to produce SHA-256 and other digests instantly, without ever sending your input anywhere.

Safe for sensitive data

Because these tools never upload your input, you can safely work with tokens, config files, and other confidential data that should never be pasted into a third-party server.
