Can I try Cap CAPTCHA for free?

Yes. Every new account gets $5.00 of Cloud Apps credit, applied automatically to your first invoice -- there is no code to enter and no card trial to cancel. On the plan Cap CAPTCHA needs, that covers your first 2 months.

How do I install Cap CAPTCHA?

Pick Cap CAPTCHA from the catalog and deploy it. There is no compose file to write, no server to prepare and no reverse proxy to configure. It comes up on a hostname with HTTPS already working.

What does hosting Cap CAPTCHA cost?

Cap CAPTCHA needs at least 512 MB memory, so the Nano subscription at $2.00/mo is the smallest that fits it. That size is a close fit for Cap CAPTCHA on its own -- if you want to run other apps alongside it, take the next plan up and share the pool.

Do I get access to the Cap CAPTCHA files and database?

Yes. Every app has a browser shell into its container, SFTP for its files. Your data is yours and you can take it out whenever you want.

Are updates to Cap CAPTCHA automatic?

Only if you turn them on. We check nightly for a new image and tell you when one exists, but applying it is your call, per app.

Can I use my own domain for Cap CAPTCHA?

Yes. Every app gets a hostname on our domain immediately, and you can point your own domain at it instead. Certificates are issued and renewed automatically either way.

Can I back Cap CAPTCHA up?

Every app includes one free snapshot -- a full archive of its data you can restore from. Keeping more than one is a paid add-on on the subscription.

What you get

Cap CAPTCHA runs on a subscription — a pool of CPU, memory and disk that you own. Deploying it takes one click, and the same pool will run your other apps at no extra charge.

A hostname with HTTPS, immediately

Your app is reachable the moment it finishes deploying, on a certificate we issue and renew. Point your own domain at it whenever you like.

Nothing exposed but the app

Only Cap CAPTCHA itself gets a public port. Anything it depends on stays on a private network unreachable from the internet.

A shell and SFTP

A real shell in the container and SFTP for its files. This is not a black box — if you want to get in and look, you can.

Updates you control

We check nightly for a new image and tell you when one lands. Applying it is your decision, per app, and a failed update rolls back to the exact image it replaced.

A free snapshot

One full archive of Cap CAPTCHA included, restorable in a click. Keep more with the snapshots add-on.

Your data, exportable

SFTP access to everything the app stores. Nothing here is locked in.

What actually runs

No mystery images. Cap CAPTCHA deploys 2 containers, and these are exactly the ones:

Running Cap CAPTCHA yourself vs. running it here

Cap CAPTCHA is free software and you can absolutely run it yourself — we would rather tell you that than pretend otherwise. What you are paying for here is the part around it.

On your own server

You write the compose file and keep it working
You configure a reverse proxy and renew certificates
You watch for new releases and apply them
You own the backups, and finding out they were broken

On Caliber Node

One click, and it is running on HTTPS
Certificates issued and renewed for you
Update checks nightly, applied when you say so
A free snapshot, restorable in a click
