About 365Lab
A one-stop collection of free online tools — built around the idea of "local-first, privacy-respecting, ready out of the box".
Who We Are
365Lab is an independent team focused on building free online tools. We believe good tools should be free, easy to use, and require no download or sign-up — and never hand your data to anyone else. From WiFi QR codes, calendars, icons, logos, math worksheets to ad-code generators, we turn everyday high-frequency tasks into polished, stable, offline-capable web tools, and keep refining them.
Our Team
Our team is made up of product designers, front-end engineers and content creators, collaborating across different cities over the internet. We love making complex things simple, and believe "tools should serve people, not the other way around". Every tool is refined through real-world use cases: readable design, clear privacy boundaries, and compatibility with low-end devices and weak networks.
We hold a "local-first" philosophy: if something can be done in the browser, we never send it to a server. That is why every 365Lab tool generates and saves locally, to protect your privacy and security as much as possible.
Our Principles
Free Forever
Core features free for the long term — no forced login, no watermark, no limits. Good tools should be within everyone's reach.
Practical First
We build only high-frequency, genuinely useful features with a clean interface — open and use instantly, without bloated and useless options.
Local & Secure
Your data is generated and saved in your browser; passwords are never uploaded, protecting your privacy to the greatest extent.
