A growing library of 41+ utilities for everyday coding, content workflows, and marine navigation — JSON formatters, AIS decoders, regex testers, GPS converters, JWT debuggers and more. Everything runs in your browser; nothing is sent to a server.
Free online tools for marine engineers, vessel operators, and maritime developers.
CodDepot is a free online collection of 41+ tools for software developers, SEO professionals, and marine engineers. Everything runs in your browser — there is nothing to install and no account to create.
Yes. Every tool on this site is free to use without limits and without sign-up. The site is funded by unobtrusive ads on the tool pages.
No. All processing happens locally in your browser. Your input never leaves your device, so the tools are safe to use with API keys, JWTs, sensitive JSON, AIS captures, or anything else you would not paste into a stranger's website.
After the first load, most tools work without a network connection — they are pure client-side JavaScript. Tools that need the network (IP lookup, embedded maps) say so on their page.
Backend, frontend and embedded developers needing quick encoding, regex, JWT or diff helpers; content writers and SEO specialists building meta tags, sitemaps and slugs; and vessel operators, marine engineers and maritime developers working with AIS, NMEA, GPS and IMO data.
