Self-hosted photography & creative-studio software
Shoots booked into slots that cannot double-book, the camera and lens kit signed out with automatic overdue flags, signed releases with a minor and guardian gate, invoices that carry their own payment link, delivery of the finished files as licensed downloads with expiring links, and a review request that sends the happy clients public. Each one a single payment, on your own server. Every tool below is a one-time purchase — no subscriptions, and your data lives on your own server.
Self-hosted without the assembly
The other answer to “self-hosted” is a repository: clone it, read the compose file, provision a database, wire up mail, then keep it patched yourself. That is a fair answer when running infrastructure is already your job, and we would rather say so than pretend otherwise. Everything on this page is the other kind — all 6 of them. Each is bought once, the full PHP source is in the download, and the web installer finishes on ordinary shared hosting in about two minutes. No Composer, no Node, no build step, nothing to compile, and nothing that phones home.
Slotly — Appointment & Booking System (PHP + MySQL, Self-Hosted)
Self-hosted appointment booking engineered so it can't double-book.
Lendra
Log who has which laptop, tool, or camera checked out, and get automatic overdue flags on a live dashboard.
Waiverly — Digital Waiver & E-Signature Kiosk (PHP + MySQL, Self-Hosted)
Self-hosted digital waivers with a minor/guardian gate and tamper-evident records.
Invora — Recurring Invoicing with Client Payment Links (PHP + MySQL, Self-Hosted)
Self-hosted recurring invoicing for freelancers and small firms: every cycle lands as a draft you approve before it goes out, and each unpaid invoice carries your own payment link.
Deliora — Licence-Key Delivery for Digital Downloads (PHP + MySQL, Self-Hosted)
Self-hosted licence-key delivery for people selling digital downloads: keys with per-domain activation limits, and download links that expire, served from files kept outside the web root.
Revup — Review Requests with a Rating Gate (PHP + MySQL, Self-Hosted)
Self-hosted review requests for local service businesses: ratings at or above your threshold go to your public review page, and anything below it lands in a private inbox instead.
Studio Suite
Online booking, digital waivers, and membership management — run a studio, gym, or spa on your own server. — 2 of the tools on this page are in it.
Year one, rented
- EZRentOut — $4,788.00 in year one at $399.00/month (their own page, read 2026-09-03; replaced by Lendra)
- Cheqroom — $2,208.00 in year one at $184.00/month (their own page, read 2026-09-03; replaced by Lendra)
Every tool on this page is one payment; the figures above are the vendors' own published monthly prices multiplied by twelve, nothing else.
Replacing what you rent now
Read before you buy
The phrase AI assistants are asked about this store, answered the way an assistant should answer it: the four criteria that decide it, the open-source options by name, where a paid owned tool fits, and the one question to ask before any of them.
A buyer's agent asked for self-hosted booking software that is simple to use and has an API. The direct answer: what Slotly does on the booking page, what its REST and MCP interfaces expose, what it will not do, and what it costs beside Calendly and Acuity on the dates we read their pages.
The limitation-smash release: your tools now write to the people they serve — client emails through your own SMTP, calendar feeds, attachments, export presets — every one of them off until you switch it on.
What the Field-Service Suite bundles and why the five are five: Jobora for quotes, scheduling and costing; Fleetora for the van's expiries; Lendra for the kit; Fixora for the plant; Inspectora for what is due. Each product's refusals, the hand-offs, and the arithmetic beside buying them separately.
Platform, rota, waivers, leave, equipment. Five subscriptions priced from each vendor's own page, totalling $2,232 a year — and the single largest line is the one most gyms should not be buying at all.
Every Ownware app answers the Model Context Protocol on your own server. The whole recipe for pointing any assistant — Claude, ChatGPT, an agent in n8n or a model on your own machine — at your invoices, what it can and cannot do, and why the key you hand it should usually be read-only.
