Companies Using ResDiary

ResDiary has 575 matched British companies, the most of any profile in our Booking & Reservations category and three times OpenTable's 193. A domain counts here when a page loads ResDiary's widget, either an iframe pointing at resdiary or a script from a resdiary host such as booking.resdiary.com. I checked a random sample of 50 live domains. 48 carried ResDiary's booking code, and 43 named a specific venue in the widget address. One pointed at widget.resdiary.com, an older host that no longer answers, and two pages wouldn't load for us. That gives 1,034 live domains, 804 matched to a company, 21st of 100 in Booking & Reservations.

Who owns it

ResDiary started in Glasgow in 2004, according to Accor's April 2018 announcement that it had bought the company. In July 2023 Access Hospitality, part of The Access Group, bought it, and described it as supporting over 9,000 venues. The Accor years still show. 15 Accor-branded hotel sites in Australia and New Zealand run ResDiary in our data, seven Novotels, six Pullmans and two ibis hotels.

Sales signal: ResDiary is now one product in a larger hospitality software suite. Expect cross-sell into its customers, and expect its customers to hear about it.

Growth trajectory

The chart reads 903 in June 2026, 989 in July and August, 1,022 in September and 1,034 in October. The July step is our coverage. The set of domains we crawl turns over every month, with dead sites dropping out and newly found ones added, and our detection signals widened over the summer. Since 16 March 2026, 125 domains dropped ResDiary from at least one hostname, and 21 of them still ran it on another hostname in our recheck.

"ResDiary's domain count understates the big groups. Cosy Club runs 38 venues through one website, so one row in this list can be a whole restaurant group." - Emma Davies, Data Analyst at TechnologyChecker.io

Sales signal: this is a stable base of about 1,000 sites, not a fast-growing one. Treat each domain as a venue or a group, and check the site's location pages before you size an account.

Who the customers are

62.91% of matched companies with a known size have 1 to 10 employees and 22.0% have 11 to 50. The difference from Zenchef is the middle: 13.12% have 51 to 200 staff, against 4.62% for Zenchef, and most of the named companies in that band are hotels. Industry says the same thing. Restaurants are 44.66% and hospitality 37.8%. The named hotels include Watergate Bay, Beaverbrook, Cromlix, Tylney Hall, The Elvetham, Castleknock and The Phoenicia Malta. On the restaurant side there are chains such as Cosy Club, Tampopo, Patty & Bun and Bundobust, and a Michelin-starred room in The Kitchin.

Sales signal: split this list in two. Hotels buy through a general manager or an F&B director and care about PMS links; restaurants and pubs buy through the owner and care about covers and no-shows.

A British and Irish base

The United Kingdom has 575 of the 804 matched companies, 71.52%, and Ireland 54. Australia (54) and New Zealand (23) together add 77. Italy (18), the United States (16) and Norway (11) follow. Domain endings agree: 487 .co.uk domains and 53 .ie in our recheck. The one large fleet is The Garlic Farm on the Isle of Wight, with 17 domains for its farm shop, restaurant and trade arms, 1.63% of the 1,040 we rechecked.

Sales signal: for UK and Irish hospitality vendors, a ResDiary site is a venue that takes bookings online and has a monthly software budget. Outside the UK, Ireland, Australia and New Zealand the list is thin.

Migration and overlap

Nothing on this page passed our switching tests. The overlaps are small: 6 domains run ResDiary beside GloriaFood's ordering widget, and that pair has been seen together on 9 domains in all. I didn't expect much else. A restaurant rarely runs two table-booking widgets for long, and ResDiary's nearest rivals by size sell mostly in other countries.

"There's no OpenTable-to-ResDiary corridor in this data. The two mostly sell to different countries, so they rarely meet on the same website." - Emma Davies, Data Analyst at TechnologyChecker.io

Sales signal: there's no visible churn wave to ride. Win ResDiary accounts one renewal at a time, on features or price.

The stack around it

WordPress runs on 58.31% of the 1,041 clean domains, Elementor on 15.75% and Squarespace on 10.95%. Google Analytics is on 64.07% and Cloudflare Browser Insights on 26.8%. Stripe shows up on 18.92%, against 0.3% on Zenchef's domains. ResDiary takes deposits and card guarantees, and its pricing page names Stripe for payments, so some of that is likely the booking flow. DoubleClick Floodlight (8.36%) and Microsoft Advertising (2.69%) point to a minority that runs paid campaigns.

Sales signal: Squarespace at 10.95% means a lot of these sites are owner-built. Website and marketing agencies for hospitality have an opening there.

What it costs

ResDiary's pricing page (checked 15 October 2026) doesn't list plan prices. The price depends on bookings per month, and you fill in a form for a quote. Bookings carry no commission from any channel. The global site lists add-ons in US dollars: $15 a month each for SMS, group bookings, POS, PMS and CRM integrations, $45 for Order & Pay, gift vouchers or Event Manager, and $50 for ResPhone. Deposits and payments carry a 1% surcharge.

Sales signal: because the core price is quoted, renewals are negotiated. That's an opening for rivals with a published price.
