Buy once, keep forever
The Core CRM is free — no licence, no trial clock. Paid add-ons are a one-time purchase. Software here is never rented.
Business software you buy once
The CRM
you own.
Free to start. Buy what you need once, and keep it forever. Your data lives where you choose — on your own machines, we never receive it.
In build — the free Core is on its way. Nothing here is for sale yet.
Own it like you own your machines
One optional bill, ever
The only recurring charge is optional hosting — and that's hosting, not software. Run it yourself and there's no bill at all.
Works offline
The Core works without internet. The marketplace, AI and sync need a connection; your day's work doesn't.
It never bricks
Stop paying and your app keeps working. A lapsed licence degrades to read and export — your records stay open and your data stays yours.
Three doors. One app.
Whichever door you come through, you download the same app — and the choices that matter (where your data lives, whether AI is on) are always yours to make at first run.
For a business
Run your team on a CRM you own
Contacts, deals and the day-to-day for owner-run teams — synced across your office, wearing your brand, with nothing rented.
Just for me
A personal install, free
The same app on your own machine, for your own things. If an add-on is worth paying for, you buy it once and it's yours.
For builders
Build on the fort
Make add-ons — and, in time, full apps — with a free Keystone pass to sign what you build. Cashel Builders opens with the marketplace.
Do the five-year maths
Subscription CRMs charge per seat, per month, forever. Put your own numbers in — this is what renting costs a small team.
paid over five years — and at the end you own nothing.
The Cashel deal
- Core CRMfree
- Add-ons you choosebought once, kept
- Optional hostingthe only recurring charge
And if you stop paying us entirely? Your app keeps working and your data stays yours, exportable. That's the deal.
Your data lives where you choose
One machine is the home of your data; everyone else connects to it. You pick the machine.
Solo
Just your computer. Everything lives on it.
Office
One always-on machine in your office; the team connects over your own network — no internet required for the day's work.
Cloud, self-hosted
Your own server, your keys, your rules.
In every self-hosted setup, we never receive your business data and are never in its path.
Prefer not to run a machine? Opt in to hosting run by us: your own single-tenant setup, encrypted and isolated — never mined, never silently accessed, with support access only through a consented, time-boxed, audited session. You can move back to self-hosting at any time.
How a stone joins the wall
Every add-on is installed by the same five checks, in order. The metaphor is the security model.
- Your purchase is recorded
- Your licence is reissued
- The signed app downloads
- Its signature is checked on your machine
- It's laid into your install — a snapshot is kept
An app that fails its signature check never joins the wall.
Cashel Builders
The fort is open to builders
Under the CRM is a platform. Builders make add-ons that businesses buy once and own — you set your price within fair bounds, and buyers can never be locked out of what they bought.
Signing is free: every builder gets a Keystone pass, and only signed work can join a customer's wall.
Where it's going: full apps, games and 3D tools on the same platform. That's the road ahead, not a shipped promise — Cashel Builders opens alongside the marketplace.
