Build on mDOS with the tools you know.

A REST interface, webhooks, a command line for power users and AI coding tools, and drop-in widgets for any website.

Ways to build

Read, write and react to what happens in mDOS.

Read, write, react

Bookings, contacts, events, orders and more.

  • A REST API for bookings, contacts, events and orders
  • Webhooks when something changes, retried if delivery fails
  • App sign-in for tools you build
  • Send data in to your own secure address

Included for developers

Every tool, in every plan.

A REST interface

Read and write bookings, contacts, events, orders and more, with app sign-in for the tools you build. It uses the same permissions and data as the rest of mDOS.

Webhooks

Your systems are told when something changes, and failed deliveries are retried.

Command line and MCP

Preview and export segments and check data from the command line or your AI coding tools, with your own permissions.

Drop-in widgets

Rooms, spaces, classes, events, shop, reviews and forms on any website, plus a group-wide search box.

One script

Banners, consent and tracking on any website through one script.

Figma plugin

Turn a Figma design into an mDOS website.

MAKE IT YOURS

Build your way

A REST interface, app sign-in and a command line for the tools you build.

Webhooks in mDOS: a successful test and the recent deliveries, each with its status and attempt

IT DOES THE LEGWORK

Webhooks retried

Your systems are told when something changes, and failed deliveries are retried.

7 widgets: rooms, spaces, classes, events, shop, reviews and forms

BUILT IN

Drop-in widgets

Rooms, spaces, classes, events, shop, reviews and forms on any website.

What it replaces

Less glue code.

Zapier chains

Fragile automations stitched between tools. Webhooks and a REST interface come with every plan. Retries are built in, so a busy moment doesn’t lose an update.

Custom widgets

Building and hosting your own booking or shop widgets. The same widgets work on mDOS sites and on any other website.

Manual exports

Exporting CSVs to move data around. Read it directly instead. Your developers read and write the data directly.

Set up by real people, supported by AI. Our team issues your keys and walks your developers through the first connection. We share sample requests and help your team test webhooks before anything goes live.

Switch at your own pace

Connect one system at a time and keep your current tools running while you build. We help your developers map the data and agree a tailored plan. Your existing integrations keep working until you switch them off.

How switching works

Three things no one else brings together

Your developers get the tools. Your business still gets the rest: AI agents doing the legwork and real experts on your side.

Support from a real marketing team

mDOS is built and operated by MDOS AI LTD. When you message or phone us, real Marketing Experts answer, on every plan, led by our Founding Partner Agency, Mr Digital. Here are five ways we help you get results.

Chat with our marketing experts

Message us from any screen in mDOS. The people who answer are marketers from our partner agencies, not a call centre.

  • Live chat on every plan, from the Chat button on every page, and you can phone us when you need to
  • Answered by marketing experts from our partner agencies, the same people who run marketing for clients
  • Ask about the software or your marketing: setup, campaigns and results
  • AI support for quick answers whenever you need one

Included in every plan

Book a call
