Tools

Small utilities, each on its own

Four focused tools that extend the Basis workspace. Each one solves a specific problem. Each one is downloadable as a standalone file — no install, no dependencies, runs in your browser.

The tools

Each tool is a single HTML file. Open it, use it, close it. No framework, no runtime, no account.

DesignTerra first, tools second

The tools extend the DesignTerra workspace. Define your tokens in DesignTerra, then use these utilities to refine, convert, and export them. Or use them on their own — each one stands alone.
