What Is NetTooling?
NetTooling is a free online toolkit for people who build, design, and market things on the web. Instead of installing separate apps or signing up for yet another SaaS trial, you get password generators, JSON formatters, IP lookups, URL encoders, QR code makers, SEO utilities, and more — all in one place, all running in your browser.
We built it because we kept needing the same small utilities across client projects: format API responses before a demo, check a domain's registration date before a purchase, generate a strong password for a staging environment. Each tool does one job well, with a short guide on the same page so you are never staring at a blank box wondering how it works.
Privacy matters here. Most tools never send your input to a server. There is no account system, no tracking of what you type, and no paywall. Pick a tool, use it, leave — that is the whole experience.
Who Uses These Tools?
- Developers formatting JSON, encoding URLs, or decoding Base64 during API work
- SEO professionals checking domain age, validating meta tags, and reviewing crawl rules
- Designers picking colors and generating QR codes for print mockups
- Writers and marketers counting words, converting case, and cleaning up pasted text
- Anyone who needs a quick answer without installing software
Common Questions
Are NetTooling tools really free?
Yes — every tool on the site is free with no hidden tiers, trial limits, or signup walls. We support the site through advertising. You can use the tools as often as you need.
Do you store the data I enter into tools?
For most tools, no. JSON formatting, password generation, Base64 encoding, and similar utilities run entirely in your browser. Your input never reaches our servers. Tools that query external APIs (IP lookup, domain age) send only the minimum data needed to fetch a result, and we do not log or store those queries.
Who builds and maintains NetTooling?
NetTooling is built and maintained by Cwebi.com, a web development team. The site started as internal utilities we kept rebuilding and grew into a public tool library. You can read more on our About page or contact us with suggestions.
Can I suggest a new tool?
Please do. Use our contact page to send suggestions. Describe the problem you are trying to solve — that helps us prioritize what to build next.
