The short version
ResDiary is a commission-free table booking system used by more than 10,000 venues in 60 countries, with paid monthly add-ons for things like pre-orders, gift vouchers, events, text messages and marketing. mDOS also takes no commission, and includes table booking, guest marketing, reviews, loyalty (Beta), gift vouchers, events and your website in one price per site, with every feature included. If you want a focused booking system and pick add-ons as you go, ResDiary fits. If you want fewer systems and an AI team (Beta) helping you fill tables, compare mDOS.
How our software compares
This compares our software’s features only. Our AI agents and our partner Marketing Experts come on top, and no single tool here includes them. Every mDOS line is live today unless it says Beta. Every ResDiary line comes from ResDiary’s own website; “Not listed” means we couldn’t find it there. Checked on 9 Oct 2026; sources are listed below.
And on top of the software: AI agents that do the legwork, and vetted Marketing Experts running it with you. No single tool compared here includes them.
Where mDOS is stronger
- Fixed pricing: one price per site with every feature included, so no surprise per-user or per-module costs.
- Marketing tools included in every plan: SEO, AI search, social media, Google Business Profile, paid ads, digital PR (Beta) and visitor intelligence. Run them yourself, with the AI team (Beta), or let our marketing team run them on the Managed plan.
- Gift vouchers, events, text messages and guest marketing are included, not monthly add-ons.
- An AI team (Beta) that spots quiet services ahead and drafts the emails to fill them, and live chat with our marketing team on every plan.
- Vetted Marketing Experts on the Managed plan: a Certified Partner Agency (such as Founding Partner Mr Digital) runs your marketing for you, under a retainer contracted and invoiced by that partner.
Where ResDiary is stronger
- A long reach in restaurants: more than 10,000 venues in 60 countries.
- Extra exposure on DesignMyNight, its diner discovery site in the UK and Ireland.
- You can start small and add only the extras you need.
