Self-hosted charity, club & association software
A membership register that knows who is in good standing and whether a motion carried, subscription invoices, signed consent forms for events, the volunteer rota, a door book that doubles as a fire roll call, and — for the shop side — a till with stock and a consignment ledger for donated goods. One payment each, running on the committee's own server rather than a per-member meter. 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 7 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.
Membora — Self-Hosted Membership Register: Standing, Quorum, Motions
Self-hosted membership register for clubs and associations: who is in good standing, whether a meeting was quorate, and whether a motion actually carried.
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.

Self-hosted digital waivers with a minor/guardian gate and tamper-evident records.

Self-hosted staff shift scheduler — a weekly rota, exact hours, double-booking caught.
Visitora — Visitor Evacuation List & Fire Roll Call (PHP + MySQL, Self-Hosted)
Self-hosted evacuation list for reception and site safety: one page naming everyone still inside, derived from the sign-in log and kept on the device for when the network dies.
Vendra — POS & Inventory System (PHP + MySQL, Self-Hosted)
Self-hosted POS & inventory engineered so overselling is impossible.
Consigna — Self-Hosted Consignment & Resale-Shop Manager
Self-hosted consignment shop software with penny-exact payouts — an open alternative to SimpleConsign.
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
- Envoy — $4,344.00 in year one at $362.00/month (their own page, read 2026-08-22; replaced by Visitora)
- SimpleConsign — $1,908.00 in year one at $159.00/month (their own page, read 2026-09-03; replaced by Consigna)
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
A club's records are fine until somebody disputes a vote. Then three questions arrive at once: who was a member that day, were enough of them present, and was the person who moved it entitled to vote. A spreadsheet of names and payment dates answers none of them.
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.
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.
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.
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.
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.
