chmonitorSign up for chmonitor Cloud
Create a chmonitor Cloud account, pick a plan, and add your first host — every plan, including the $0 Free plan, goes through a Polar checkout with no card required for Free.
chmonitor Cloud (dash.chmonitor.dev) is the hosted version of chmonitor — sign up, pick a plan, and connect your ClickHouse or Postgres in minutes. No infrastructure to run.
Self-hosting instead?
Self-hosted chmonitor (Docker / Kubernetes / your own Worker) has no plans or billing at all — every feature is unlocked. See Getting started or Self-host.
The sign-up flow
Sign in
Before signing in you can explore a live, public read-only demo cluster on the Cloud dashboard with no account. Signing in (via Clerk) hides the demo and moves you to your own setup.
Pick a plan
The first time you sign in with zero hosts of your own, chmonitor shows the /setup page with a plan picker before you add a host:
| Plan | Price | Hosts | Seats | AI agent |
|---|---|---|---|---|
| Free | $0 | 1 | 1 | 5 messages/day |
| Pro | paid, monthly or yearly | multiple, overage billed | multiple | higher daily allowance + overage |
| Max | paid, monthly or yearly | multiple, overage billed | multiple | higher daily allowance + overage |
| Enterprise | custom | unlimited | unlimited | unlimited (BYOK) |
Every plan, including Free, goes through Polar checkout — Free is a real $0 Polar subscription, not a client-side skip. Choosing any plan (Free, Pro, or Max) briefly redirects your browser to a Polar-hosted checkout page and back:
- Free — the checkout collects no card, then returns you straight to chmonitor.
- Pro / Max — the checkout collects a payment method before returning you to chmonitor.
Add your first host
Add a ClickHouse or Postgres connection (see ClickHouse user & grants for the minimal grants, or Connect a firewalled ClickHouse if it's behind a firewall). Free is capped at 1 host and 1 seat; upgrade if you need more.
An active subscription is required first
Adding a host needs an active subscription on the account — Free included. Without one (checkout skipped or abandoned), the API rejects the request with 402 subscription_required. Complete the Free checkout above, even though it charges nothing, before adding a host.
Changing plans later
Upgrade, downgrade, or manage payment from /billing at any time — you are not locked into the plan you picked at sign-up.
