FAQ
Questions, answered.
Is WebRul Tools really free to use?
Yes. Every tool on the platform is free to use with no sign-up required. Advanced enterprise features and private deployments are available on request.
Do you store or upload my files?
Wherever possible, tools run entirely in your browser. When a tool needs a server round-trip, files are processed in-memory and never persisted beyond the request lifecycle.
Can I use these tools commercially?
Yes. WebRul Tools are free for personal and commercial use. Enterprise SLAs, private tenants, and white-label deployments are available for teams that need them.
How often do you ship new tools?
We ship weekly. Our public roadmap targets 200+ production tools across PDF, image, SEO, text, developer, and calculator categories.
Can I request a specific tool?
Absolutely. Tool requests from real teams shape our roadmap — send us a note from the contact page and we’ll prioritize it if it fits the platform.
