Developer Utility Toolkit

DevFixpro collects 46 focused developer utilities that each solve one small, recurring problem without asking you to install anything or create an account. The catalogue is split into a few working groups. Formatters make dense machine output readable, covering JSON, XML, SQL, JavaScript, HTML, and CSS, and they are usually the first thing to reach for when a payload or a stylesheet arrives as one long line. Converters translate between representations that different tools expect, such as JSON and CSV, numbers in different bases, and colors described as hex, RGB, or HSL. Encoders and decoders handle the transformations that text channels require, including Base64, Base32 and Base58, URL encoding, HTML entities, and the escaping each programming language expects. Generators produce values you should not invent by hand, like UUIDs, strong passwords, hashes, and placeholder copy. The remaining groups cover text cleanup, timestamps and time zones, network and HTTP debugging, and cryptographic helpers such as HMAC and AES.

Two properties hold across the whole set. The first is that every tool runs locally in your browser using the platform Web APIs, so the values you paste, whether a token, a private key, or a customer record, are never transmitted to a server. The second is that the tools are deliberately single-purpose: each one does one job, shows its result as you type, and explains the underlying concept so the output is not a black box. If you are not sure which tool you need, start from the category that matches the shape of your problem, or use the search field to filter the list by name and description.
