About ZIV LABS

ZIV LABS is an independent product studio operated by an individual developer based in Japan. We design, build, and maintain small web products that solve concrete, everyday problems.

What we do

We focus on focused, lightweight tools that people can use immediately — no sign-up, no installation. Each product is published under its own subdomain of ziv-labs.com and is maintained directly by us.

How we work

• Start small. Every product begins with a specific problem we have run into ourselves.
• Ship early. We publish a focused first version instead of waiting for a perfect one.
• Improve from real use. Bug reports and feature requests directly shape what we fix and build next.
• Respect users. We process data in the browser whenever possible and collect only what a product needs to work.
