~ $ chasen login
We do everything. You run chasen deploy.
On your own server, Chasen is free and you run the server. In Chasen cloud we do everything for you: we create the server, harden it, update it, and back it up. You run two commands.
€9a month for your account,
with any number of servers
- Servers at Hetzner's price, with no markup
- No seats, and no meter on traffic
- Leave any time: it is the same open source Chasen
- Not open yet. The list gets it first
One email when the cloud opens, with your key for chasen login. Nothing else.
[01] the step up
The same Chasen, with the server done for you.
With the open source version, all of this is your job. Here it is ours: getting a server, making it safe, keeping it updated, and keeping the copy of your data.
- The server.
- Your first deploy creates it at Hetzner, in Europe or in the USA. You pick the size, and you see Hetzner's price before anything is created.
- The hardening.
- Every server is locked down before your first app runs on it. That is our job, not yours.
- The updates.
- The server installs its security updates by itself, every day. A kernel fix needs a restart: the server does that by itself too, in the hour when your apps have the least traffic. You never log in to patch a server.
- The names.
- Every app gets a domain and an HTTPS certificate at its first deploy. Your own domain is one more command.
- The backups.
- Each server gets its own bucket. Every SQLite database is copied each hour, and every change follows about one second behind.
[02] the first deploy
Log in, deploy, pick a server.
There is no dashboard and no setup form. The first deploy of an app asks where it goes, with the sizes and the prices that Hetzner has at that moment.
$ chasen login $ chasen deploy shop is your first app. Chasen creates a server for it. Which one? 1 a new server Europe cx23 2 vCPU, 4 GB memory, 40 GB disk €x.xx a month at Hetzner 2 a new server USA cpx11 2 vCPU, 2 GB memory, 40 GB disk €x.xx a month at Hetzner 3 a new server Europe cx33 4 vCPU, 8 GB memory, 80 GB disk €x.xx a month at Hetzner Pick the region of your customers. A server costs what Hetzner charges at this moment, without VAT. Chasen is €9.00 a month for your account, with any number of servers. Choice [1]: 1 Creating your server (cx23 in Europe). This takes about 3 minutes, one time. Deployed shop 3f9a2c1 https://shop.a1b2c3.chasenhq.com
- The default is always the cheapest option: a server you already pay for, or the smallest new one.
- The next app asks again. Put it on the same server, at no extra cost, or on a new one.
- In CI there is no question:
chasen deploy --on a1b2c3or--newanswers it ahead.
[03] the price
€9 a month. Servers cost what Hetzner charges.
One flat price for your account, however many servers and apps you have. No seats, no meter on traffic, and no markup on a server.
- as many servers as you want, for the same €9
- as many apps and addons as a server holds
- one key for the account: share it with your team
- nothing metered
Without VAT. The smallest server is a few euros a month. Hetzner's prices →
[04] updates
Your server patches itself. Here is what that costs you.
A server that nobody updates is the real risk of running your own. So every cloud server keeps itself current, and we tell you plainly when that touches your apps.
| what | when | your apps |
|---|---|---|
| Security updates of the server | every day, by themselves | keep running |
| A security fix in the kernel | a smart restart: the server picks the hour with the least traffic | away for under a minute, then back by themselves |
| Chasen itself | each night, when there is a new release | keep running |
| Your apps | only when you deploy | no downtime: the old version serves until the new one answers |
[05] questions
The bill stays the same.
A flat price and one server is a choice. Here is what it means for you.
How is this different from Vercel?
Vercel has a free plan, with custom domains, and it is great for a personal project. It is not for a business: its terms allow non-commercial use only. A business pays $20 a month for each developer, plus a meter on traffic (as of October 2026). That meter is the real difference. On Vercel, a traffic spike can surprise your bill. On Chasen, it can slow your server down, and the bill stays the same: €9 plus the server. Your call.
Europe or the USA?
Where your customers are. Europe is the default and the cheapest: Hetzner's smallest servers exist only there. A server in the USA saves an American visitor about a tenth of a second on each request. One app runs in one place. Cloudflare in front makes the rest fast everywhere.
Can I have more than one server?
Yes. The first deploy of each new app asks where it goes: a server you already have, or a new one. A second server costs only what Hetzner charges for it: Chasen stays €9 a month. Most people need the second server later than they think.
What does a server cost?
What Hetzner charges for it, with no markup. The €9 of Chasen is for your account, not for each server. The deploy shows Hetzner's price of that moment for each size, before it creates anything.
Will my server restart by itself?
Yes, and that is on purpose. A security fix in the Linux kernel takes effect only after a restart, and a server that never restarts runs with known holes. Yours restarts only when a fix asks for it, and it picks the moment: the server counts its own requests, and restarts in the hour of the day with the least traffic. Your apps are away for under a minute and come back by themselves. If that is too much for your app, write to us: the automatic restart can be off. With it off, a kernel fix waits until you ask for the restart, so the server runs with a known hole until then.
Do I get SSH to my server?
No, and you do not need it. Keeping the server safe is our job, and it stays safe because nobody logs in to it. You get what people use SSH for: chasen ssh opens a shell in the container of your app, chasen logs follows its logs, chasen run runs one command, and chasen download gives you the databases of any backup.
Can I leave?
Yes. The cloud runs the same open source programs you can install yourself. Your app is a Dockerfile and its data is SQLite files, so it deploys to your own server with no change. chasen download gives you your databases, one file for each backup.
When does it open?
The cloud is not open yet. The software behind it is done and runs my own apps: it is the open source Chasen you can install today. What is missing is sign-up and payment. Join the waitlist and you get one email when it opens, with your key for chasen login.
