Self-hosted school & training-provider software
Course and appointment bookings, a competency matrix that knows what expires when, certificates a learner or an employer can verify on your own domain, signed consent forms, the reception book that becomes a fire roll call, fee invoicing, and the staff rota and leave behind it — bought once and kept on the server that already holds your learner records. 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 8 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.
Trainora — Self-Hosted Training Matrix: Competencies, Expiry, Evidence
Self-hosted training matrix: who has what, what has run out, and what runs out next — every expiry computed from the date it was achieved, never stored.
Certora — Public Certificate Verification Page (PHP + MySQL, Self-Hosted)
Self-hosted certificate verification for training providers and awarding bodies: every certificate carries a unique code an employer can check on a verify page you host yourself.
Waiverly — Digital Waiver & E-Signature Kiosk (PHP + MySQL, Self-Hosted)
Self-hosted digital waivers with a minor/guardian gate and tamper-evident records.
Slotly — Appointment & Booking System (PHP + MySQL, Self-Hosted)
Self-hosted appointment booking engineered so it can't double-book.
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.
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.
Rostera — Staff Shift Scheduler & Rota (PHP + MySQL, Self-Hosted)
Self-hosted staff shift scheduler — a weekly rota, exact hours, double-booking caught.
Leavora — Staff Leave & PTO Tracker (PHP + MySQL, Self-Hosted)
Self-hosted staff leave & PTO — accruals, working-day requests, approvals, and live balances.
Studio Suite
Online booking, digital waivers, and membership management — run a studio, gym, or spa on your own server. — 3 of the tools on this page are in it.
Year one, rented
- iSpring Learn — $8,292.00 in year one at $691.00/month (their own page, read 2026-08-22; replaced by Trainora)
- Envoy — $4,344.00 in year one at $362.00/month (their own page, read 2026-08-22; replaced by Visitora)
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
Five registers, no payroll: what the Workforce Suite bundles, what each product refuses to do, how the rota, the timesheet, the leave calendar, the onboarding plan and the training matrix hand off to each other, and the arithmetic beside buying them one by one.
Most training spreadsheets have two states: has it, or does not. That collapses three different problems into one column, and the one it hides is the one an auditor opens with. The case for a matrix that distinguishes lapsed from never-done from does-not-apply.
A hosted verification URL is a dependency. Cryptographic badges are a standard. A self-hosted verify page is a third thing. Here are all three trust models compared honestly, including where the self-hosted one is the wrong choice.
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.
