Why teams move.
Consentmo is a Shopify app, priced flat per store and built around the Shopify admin. Katla also installs on Shopify, but it is platform-agnostic: when the storefront sits next to a marketing site, a docs site or an app, all of them share one cookie inventory, one set of consent records and one generated policy. Add headless mode, a React and Next.js SDK, a CLI and an MCP server, and it is the tool for the whole estate rather than for the store alone.
The consent layer, without the UI you did not ask for.
- Guard-only mode with no bundled interface
- window.KatlaConsent plus a katla:consent event on every change
- A React and Next.js SDK with hooks, or plain DOM if you prefer
- The hosted banner is still one line away when you want it
4 KB headless, 18 KB with the banner - and it runs before the trackers do.
- About 4 KB over the wire in headless mode
- About 18 KB with the full hosted banner and your cookie data
- Served from a CDN and cached at the edge
- The guard runs ahead of trackers, so blocking is not a race
Cookies classified and described without you writing a word.
- Automatic classification of newly discovered cookies
- Descriptions generated per locale, overridable when you want your own wording
- Cookie and privacy policies generated from your real scan data
- An MCP server, so Claude or ChatGPT can audit cookies and query consent for you
One consent layer across everything you run.
- Script tag, React and Next.js SDK, or a WordPress and WooCommerce plugin
- A CLI, so onboarding thirty sites is a script rather than an afternoon
- A full API, and an MCP server on top of it
- Per-locale policies and descriptions from the same source of truth
A price on the website and a script tag to start.
- Published pricing - no quote, no call, no procurement cycle
- Flat per site, per month, with no usage overage charges
- A free tier that scans and generates a policy without a card
- One script tag from nothing to a working banner
$0-$64 / month per store
- Charged on
- Flat per store, by feature tier - unlimited banner impressions, so no traffic overage
- Free tier
- Free plan with unlimited impressions, a cookie scan and basic script blocking
