45 tools · free · yours to keep
Take them with you.
Every tool here is a single self-contained HTML file. Download one and it works forever — no internet, no install, no account, no expiry. Double-click it and it opens in your browser exactly as it does on this site.
All 45 in one Windows app In build
A signed installer with a Start-menu icon, for people who would rather not keep track of 45 separate files — and for a locked-down machine where the browser is not an option. It will be $9 once. Every tool below stays free either way; the bundle sells the convenience, never the capability.
Individually · free
Or take just the ones you want
No bundle needed and nothing to pay. Right-click and save, or use the button on any row. Each file is between 20 KB and 1.8 MB depending on what the tool has to carry with it.

Small utilities that install properly
Not trials and not teasers — finished tools, given away. They are waiting on a code-signing certificate, because an unsigned installer makes Windows warn about an unknown publisher and that is a poor way to meet someone.

- Great Scott RecorderRecord a screen or just the audio. Two buttons.In build
- EdgeDockA shortcut rail on the edge of the screen that hides when you don't need it.In build
The one honest catch
A downloaded copy is frozen. If a tool gets a fix or a new feature later, your saved file will not see it — it is a photograph, not a subscription. For a converter that does one job that is usually fine, and it is the price of a file that needs nothing from us ever again. Come back to the site for the current version any time.
The web versions on this site are always the newest, always free, and always will be.
