Email, calendar, and files on a server you own. Nobody mining it, nobody training AI on it — and nobody who can lock you out. Installed in minutes.
The same jobs, done on hardware you control. One install, one login, one place to back up.
Your domain, your archive, your server. Fast webmail plus native apps, with outbound delivery handled by a real mail provider.
Shared household and team calendars, invitations, recurring entries, and reminder or daily-summary emails.
Files stored as ordinary files, synced to desktop and phone. Photo backup, thumbnails, and optional end-to-end encryption.
One address book behind mail and calendar. Bring the vCards you already have; take them with you whenever you like.
Registration, waiting lists, recurring schedules.
Let people book time without a third-party service.
Your own model, on your own hardware.
Sell products and subscriptions from your server.
Backups, upgrades, and fleet management.
You have read the post. Somebody ran their own mail server for two years, and then gave up because their mail kept landing in spam.
They were right about the hard part. Getting a fresh IP address trusted by Gmail and Outlook is a grind that has nothing to do with owning your data — and losing that grind means your mail quietly disappears.
So Joinery does not fight that battle. Your mail lives on your server; only the last hop is borrowed. Outbound messages go out through an established mail provider — Mailgun, Amazon SES, or any SMTP smarthost you prefer — with SPF, DKIM and DMARC configured for you during setup. Your archive, your domain, your rules, delivered with a sending reputation that already works. It is the same architecture the self-hosting community recommends to itself: your MX, their SMTP.
Joinery can also run a small mail relay in front of your server. This is a security and privacy feature, not the deliverability fix — worth being precise about:
Your own server never has to sit on the public internet accepting connections from strangers.
This is the one promise no hosted provider can make you, however good their intentions are.
One automated flag, one appeal form, one form letter, and fifteen years of mail is gone — along with every account that used that address to sign in. On your own server there is no flag to trip and no appeals process, because there is nobody above you.
Terms change. A setting appears, already on, and suddenly a model is reading your inbox to be helpful. Joinery ships an AI assistant, but it runs on your hardware, only if you install it, and encrypted content is architecturally blocked from leaving your server through it.
Your data is a folder of files and a Postgres database. Backup is rsync and a pg_dump. Leaving is copying a folder. We would rather you stay because the software is good than because leaving is painful.
Bring the archive, keep the address you actually want, and stop being one automated flag away from losing all of it.
Four things done properly instead of forty done badly. Plain files, Postgres, and upgrades you do not have to hold your breath through.
One server, everyone's mail and calendar, and somewhere for the photos that is not somebody's training data. You administer it; they just use it.
Same software, same ownership, whichever rung you pick. Your server, your data, in every case.
Optional, paid once, and never in the way of the free suite.
We would rather tell you than have you find out.
Joinery is in beta. The suite is complete and in daily use, and it is honest to call some parts younger than others — the desktop sync client in particular is still pre-release. Every page on this site labels maturity where it matters rather than painting the whole thing “production ready.”
It is built by one developer, in the open. No investors, no board, no growth targets, and nobody who needs your data to be worth something. You can read the code that touches your mail.
Real things already run on it. ScrollDaddy, a commercial DNS filtering service with paying customers, runs entirely on Joinery — accounts, billing, scheduled tasks and all. So does this website.
You can check every claim on this page. That is the point of shipping software you run yourself: nothing here depends on trusting us.
Free to self-host, forever. $39.99 if you would rather have the afternoon back.
