Frequently asked questions

Site-level questions about ListShift. Tool-specific FAQs live on each tool's page.

Is ListShift free?
Yes. Every one of the 130 tools is free to use, with no sign-up. ListShift Plus ($12/year) adds saved pipelines, file imports, longer lists, no download wait, and no ads.
Does my data get uploaded anywhere?
No. Every transformation runs entirely in your browser - your list never leaves your device, and nothing is stored server-side. See our privacy policy for the full architectural guarantee.
Do I need to sign up to use ListShift?
No. Every free tool works without an account. You only need an account to use Plus features (saved pipelines, file imports).
How big a list can ListShift handle?
Free accounts cap at 100 items per list. Plus removes the cap entirely - the only ceiling is your browser's memory, which comfortably handles tens of thousands of items on most devices.
What's the difference between Plus and free?
Free gives you all 130 tools, no sign-up, fully client-side. Plus adds saved pipelines, file imports (CSV / JSON / XML / Excel / etc.), unlimited list size, instant downloads, and no ads. $12/year, cancel any time.
Do you have an API?
API access is available on the Team tier alongside SSO and central billing - contact us for pricing. We deliberately keep ListShift's core tools client-side, so the API is for orgs that need server-side automation.
