About Teamz Lab Tools

Teamz Lab Tools is a collection of 1,400+ free browser-based tools built by Teamz Lab Ltd, a software development company. Every tool runs entirely in your browser — no data is ever sent to our servers, no account is required, and every tool is free to use.

Who We Are

Teamz Lab Ltd is a registered software company that builds web applications, mobile apps, AI integrations, and developer tools. Founded in 2023, our team specialises in creating practical software that solves real problems.

Our apps are available on both major platforms:

• Google Play Store — Android apps by Teamz Lab
• Apple App Store — iOS apps by Teamz Lab Ltd

Our Approach to Tools

Every tool on this site follows three core principles:

• 100% Private — All calculations and processing happen in your browser. Your data never leaves your device. We don't track inputs, store results, or share anything with third parties.
• No Sign-Up Required — Every tool works instantly. No email, no account, no friction. Open the page and start using it.
• Free Forever — All 1,400+ tools are free to use with no usage limits. We sustain the project through non-intrusive advertising.

Our tools automatically save your inputs locally so you can pick up where you left off. They work offline once loaded, and are optimised for both desktop and mobile devices.

What We Build

Our tool library spans finance, tax, health, career, development, design, and more — available in 14 languages across 40+ regional hubs. Categories include:

• Finance & Tax — Mortgage calculators, tax estimators, investment planners, retirement tools for US, UK, AU, DE, JP, and more
• Career & Freelance — Resume builders, salary calculators, invoice generators, project pricing tools
• Developer Tools — Code formatters, API testers, regex builders, JSON tools, colour converters
• Health & Wellness — BMI calculators, calorie trackers, sleep calculators, fitness planners
• AI-Powered Tools — Text rewriters, summarisers, and generators using on-device AI (Chrome AI and Transformers.js)
• Design & Image — Background removers, colour palette generators, logo makers, image converters

Our Methodology

Financial calculators use official tax brackets, rates, and formulas published by government agencies (IRS, HMRC, ATO, etc.). We update rates annually when new figures are released. Health tools follow established medical formulas (Harris-Benedict, Mifflin-St Jeor, etc.) and include appropriate disclaimers. All tools are tested for accuracy with sample data before publication.

If you find an error or outdated rate in any tool, please let us know and we will fix it promptly.
