| Free tier | Free edition: permanently free, 1 Mbps, random URL subdomain, random TCP port, HTTP / TCP tunnel support, 1 online cpolar process, 4 tunnels per process. [translated] unit unlimited; metered on none |

| Limits | - per-ip-shaping (binding) 1 Mbps on the free plan source
- request-rate connection-rate limit per tunnel endpoint; excess HTTP connections get 429, excess TCP connections are closed source
- request-rate 1 online process and 4 tunnels on the free plan source
|
|---|
| Binding | per-ip-shaping Traffic is unlimited but 1 Mbps is 10.5 GB/day, about 324 GB over 30 days, against 3.24 Mbps for 1 TiB/month. The shaping binds three times. |
|---|
| Identity | email An account is an email address: the pricing FAQ defines one online process as one email account installing a user on one machine, and says multiple machines means registering multiple email accounts. |
|---|
| Egress | No byte quota on any plan: every plan is sold with traffic not limited. The free plan's 1 Mbps caps a saturated month at about 324 GB.; ingress: tcp free allowance: none published |
|---|
| Interface | cli Web UI on localhost:9200 after install, a CLI with authtoken authentication, and a dashboard at dashboard.cpolar.com. |
|---|
| Tooling | vendor client on Windows/Linux/NAS/ARM, authenticating with a token from the dashboard; wg-quick cannot attach to it |
|---|
| Composes with | Carries HTTP and TCP only, so it composes with a web service or an SSH control channel and not with WireGuard. |
|---|
| Reliability | Exceeding the connection rate limit returns 429 on HTTP and silently closes TCP and TLS connections; the vendor documents neither the threshold nor a reset window. |

| Notes | The best-identified Chinese tunnel vendor in English lists, with an email-only account, and the only one here with a documentation set large enough to make the absence of UDP meaningful. No English pricing arm was found: www.cpolar.com/en/pricing returns 404 and the only pricing page is the Chinese one. |
|---|
| Evidence note | documented Pricing table read first-party and the whole documentation site searched for UDP with zero hits. A negative search is strong evidence here because the same docs page documents TCP, HTTP and TLS tunnels by name. |
