About Toolbench

Toolbench is a set of 20 free tools for marketers, developers and small business owners. Every tool runs in your browser, so what you paste or open is never uploaded.

Who runs this site?

Toolbench is built and maintained by Sam Barth, a HubSpot consultant. The tools cover the small jobs that come up around CRM and website work: tagging campaign links, cleaning lists before import, checking structured data and robots.txt, and converting data between formats.

Why do the tools run in the browser?

Client lists, exports and drafts are often private. Doing the work with JavaScript on your own device means there is no server to send your data to. Once a tool page has loaded, most tools keep working even if you go offline.

How is the content checked?

• Each tool is tested in a browser before it is published.
• Prices and limits are only quoted from a public source, with the date they were last checked.
• News write-ups are original summaries that link to the primary source for every fact.
