- Local by default — developer and text tools process data in your browser.
- Genuinely useful — every tool has real features, clear errors, and explanatory content.
- 47 focused tools — not hundreds of thin keyword pages.
FAQ
Are ToolForge tools really free?
Yes. V1 tools are free to use in your browser with no account required.
Do you upload my data?
Sensitive developer and text tools process input locally in your browser. We do not need your content to make the tools work.
Do I need to create an account?
No. There is no authentication in V1 — open a tool and start working.
Will there be ads or premium tools later?
Possibly. The architecture is ready for ethical ads and premium features, but the core utilities stay focused on usefulness and privacy.
