Who we are
Jisubao is an independent online tool collection. Our goal is to turn everyday productivity tools into web pages that are "open and use, 100% free" — saving time for developers and office workers. We've shipped 16+ tools (JSON, QR code, password, timestamp, color, text diff and more), and we keep adding.
Why 100% free
We believe good tools shouldn't cost money. All features are free forever, no signup, no paywall. Running costs (domain, hosting, bandwidth) are tiny, covered by ads & referral partnerships — the more you use and share, the longer we stay free.
Our promise
- Tools run in your browser locally; your data is not uploaded or collected.
- No sales pitches, no renewal traps, no hidden charges.
- Original, compliant content — no spammy redirects or plagiarism.
Contact & Collaboration
Questions, suggestions, or bug reports? We'd love to hear from you. All Jisubao tools are free forever with no forced payment — beware of scams impersonating us.
