Spillway, run for you by the people who build it
Your own Spillway instance, kept up to date and backed up, at a price you see before you start and a monthly cap you set. Hosting is in private beta: tell us about your site and we will invite you.
Your own instance
Every site runs on its own machine, volume and database on Fly.io. Nothing is shared with another customer's site, so their traffic or their modules never touch yours.
Kept current and backed up
We run the Spillway updates and keep backups: daily for 30 days on Site, hourly for 90 days on Campus, hourly for a year on Enterprise.
No bill surprise
Each plan includes its allowances. Past them, usage bills at published rates up to an overage budget you set, and a budget of $0 makes the plan price a hard cap.
How the beta works
The private beta is for invited accounts, on the Site plan, billed monthly. You get an address on Spillway's platform domain from the start; your own domain, the other plans and yearly billing come with the launch.
- Tell us about your site. Write to hello@spillwaycms.com with what you are building and roughly how much traffic you expect.
- Start a site. Once invited, you pick a name, a region and a theme or kit, and pay through Stripe.
- Open your admin. The site is built in a couple of minutes and you land in its admin, signed in, on the getting started checklist.
You can always leave
A hosted site is the same Spillway you can run yourself. Export it at any time, content, media, users and settings, and run it on your own server, Render, Railway or anywhere Docker runs. Self-hosting stays first-class: hosting is a convenience, not a lock-in. See the install guide.
Questions
Where do sites run?
On Fly.io, in a region you choose when you start the site. The price is the same in every region.
What happens when my site gets more traffic than the plan includes?
Bandwidth past the allowance costs $0.10 per GB, up to your overage budget. When the budget is reached, Spillway keeps the site up and inside it for the rest of the month by caching longer and running smaller, never by deleting anything or taking the site down.
Is there a discount for schools and nonprofits?
Yes: 30% off for education and nonprofits, and yearly billing at the price of 10 months for 12 once it is available.
Do I get support?
Email support is included with every plan. Priority support is an add-on.
Can I use AI features?
Yes. Hosted sites use Spillway's AI keys with fair use, then credits.
