ToolClack is an independent software studio. We build small, focused tools that live where you work: the browser.
Browser extensions, web tools and whatever earns its place next, each built to do one job well. The free tools on this site run entirely in your browser, no signup and no upload; the products follow the same philosophy, with FillKit leading the family.
Every product starts from the same rule: your data stays in your browser unless a feature genuinely needs a server. Accounts, sync and backups are optional layers, never the price of entry.
Products are updated continuously, and every release is documented in the changelog. If something breaks, the support page is the fastest route to us. Read the changelog →
The quickest way is the support form, or for anything else. Feedback and feature ideas are read by the people who build the products.
Practical tools for everyday work, built with care and respect for your data.
