Questions & Answers

As answered by people managing SetMore and OpenSlot.

What makes your product unique?

OpenSlot's answer:

OpenSlot combines a simple customer booking journey with the practical controls a service business needs. Customers book from one shareable link without creating an account, while the business manages services, staff, working hours, buffers, notice periods, time away, payments and appointments in one hosted platform. It is free to start, requires no WordPress installation or collection of add-ons, and is designed to keep booking administration calm and clear.

Why should a person choose your product over its competitors?

OpenSlot's answer:

Choose OpenSlot if you want hosted appointment booking without a complicated setup. The free plan includes one user, one service and up to 20 bookings per month with no card required. Paid Solo and Team plans add unlimited services and bookings, deposits and payments, email reminders, custom branding, staff scheduling, permissions and reports. Businesses keep control of availability, and customers get a focused booking experience that works well on mobile.

How would you describe the primary audience of your product?

OpenSlot's answer:

OpenSlot is built for independent professionals and small service teams that rely on scheduled appointments. Its primary audience includes therapists and counsellors, coaches, consultants, tutors, salons, personal trainers, pharmacies and healthcare practices. It supports online, in-person and customer-location appointments for businesses serving customers worldwide.

What's the story behind your product?

OpenSlot's answer:

OpenSlot was created to solve the repeated back-and-forth behind the question, "What times do you have?" Appointment-based businesses lose useful time to messages, manual diary checks and follow-ups. OpenSlot replaces that process with one clear booking link, real availability and one place to manage the details. The product launched in August 2026 with a free plan for solo businesses and paid plans for growing professionals and small teams.

Which are the primary technologies used for building your product?

OpenSlot's answer:

OpenSlot is a server-rendered web application built with PHP 8.2 and MySQL, hosted on Apache. Its interface uses Tailwind CSS, with Node.js used only to compile the production stylesheet. Stripe supports subscriptions and appointment payments, while optional Google and Microsoft integrations provide calendar synchronization.

Who are some of the biggest customers of your product?

OpenSlot's answer:

  • Customer names are not publicly disclosed at this stage. OpenSlot is newly launched and is designed for independent professionals and small service teams.
