As answered by people managing Sequel Pro and Dev-Toolbox.io.
Dev-Toolbox.io's answer:
Everything runs in your browser. Most online developer tools post your input to a server to process it, which makes them unusable for anything sensitive — API keys, access tokens, production records, client data. DevToolbox.io does the work locally, so there is nothing to upload and nothing to retain. The only thing that ever leaves the browser is a Share link you explicitly create.
Dev-Toolbox.io's answer:
Three reasons. Privacy: your input never reaches a server, so you can paste a real JWT or a production payload without thinking about it. Breadth: 30 tools in one place, so you are not bouncing between a different single-purpose site for every task. No friction: no account, no rate limits, no ads interrupting the tool, and each tool is its own URL you can bookmark or link to directly.
Dev-Toolbox.io's answer:
Working software developers, and anyone adjacent to them — QA engineers, data engineers, technical support staff and students. The common thread is someone who needs to format, convert, decode or compare something quickly, mid-task, and does not want to install anything or hand their data to a third party to do it.
Dev-Toolbox.io's answer:
It started from the habit of searching for "json formatter" or "base64 decode" several times a week and landing on whichever ad-heavy site ranked that day, never knowing what happened to the data pasted in. DevToolbox.io was built to be the bookmark that replaces those searches: the same tools, in one place, that run in the browser and do not ask for anything.
Dev-Toolbox.io's answer:
Next.js and React with TypeScript, styled with Tailwind CSS and deployed on Vercel. The editors are Monaco, the same editor component used by VS Code. Heavier work — parsing, diffing, formatting and minifying — runs in Web Workers so a large document never freezes the page. Established parsers do the real work rather than hand-written ones: Prettier and Terser for JavaScript, the yaml library for YAML, marked for Markdown and DOMPurify for sanitization.

Doing some Googling Sequel Pro looks very promising as well as Navicat. Ideally something FOSS or at least free, but willing to pay if needed. Source: over 5 years ago
