ngseed is a free collection of 36 small, focused developer tools — things like a JSON formatter, a JWT decoder, a hash generator, and a regex tester — built to solve the everyday annoyance of hunting down a trustworthy site every time you need to format some JSON or decode a base64 string.
Most “online tool” sites are cluttered, slow, or vague about what happens to the data you paste in. ngseed started as a personal itch: a single, fast place to keep the utilities I reach for daily while writing and debugging code, built the way I'd want to use them myself — clean, quick to load, and with no sign-up wall in front of a five-second task.
Every tool on ngseed runs entirely in your browser using JavaScript — nothing you type or paste into a formatter, converter, or generator is uploaded to a server for processing. That's a deliberate design choice, not a marketing line: it's simply the only reasonable way to build a tool that people will trust with API keys, JWTs, config files, and other sensitive-looking text. See the Privacy Policy for the full picture, including how cookies and advertising fit in.
Alongside the web UI, ngseed exposes an MCP server so the same formatting, encoding, and conversion utilities can be called directly by AI coding assistants that support the Model Context Protocol.
ngseed is an independent, self-funded project — not a company product. It's maintained in spare time and grows one tool at a time based on what actually gets used. Suggestions, bug reports, and tool requests are always welcome via the contact page.
