| Free tier | 'You can use Killercoda completely for free!' and 'If you open any scenario then you can use it for one hour max, after which the environment of the scenario is deleted. Then you can reload your browser tab to get a new environment which you can use for one hour.' and 'There are no daily or monthly usage limits.' unit hours; metered on wall-clock |
|---|---|
| Price | none stated |
| Limits |
|
| Binding | retention-clamped One hour and a tab close is the whole lifetime, which is the shortest useful window after Binder's ten-minute reap. |
| Identity | email no card, no phone, no document: 'Users wanting to use your scenarios will just need to register for free on Killercoda.' The FAQ adds 'Are some email domains blocked? Yes, certain email domains are blocked due to security measures', so the email must be from a domain the vendor accepts, and the list is not published. |
| Egress | not published: no traffic allowance is stated in the FAQ or the pricing page. The environments are built to run labs, so outbound package installs work, but no figure is given. |
| Per-object cap | 'Open up to 3 scenarios at the same time' is a paid-PLUS feature, so a free account holds one environment at a time |
| Retention | 'All environments are ephemeral, isolated from each other, and deleted once the browser tab is closed.' Nothing persists between sessions. |
| Interface | rest A browser terminal into an ephemeral Linux environment, plus a remote desktop for some scenarios. No SSH from outside and no public inbound port for user services. |
| Tooling | a browser; a free account |
| Composes with | A one-hour Linux sandbox with no card, useful for a throwaway shell or a Kubernetes exercise, and too short-lived to be a node. |
| Reliability | No reliability event observed. The FAQ names short-term rate limits and Captcha challenges when many users share an IP, which is a capacity control rather than an outage. |
| Notes | Free, no card, no phone, and renewable all day because there are no daily caps: the constraint is that each environment dies at one hour or when the tab closes. That makes it a lab bench rather than a host. Two things are unverified: the per-environment shape (no vCPU or RAM figure is published on any page read) and which email domains are blocked. The existing killercoda record prices it as a trial at 1 hour with a 4-hour paid tier; this record adds the no-daily-cap statement and the registration detail that the earlier one lacked. |
| Evidence note | documented The one-hour limit, the tab-close deletion, the absence of daily or monthly caps, the registration requirement and the blocked-domain policy are quoted from Killercoda's own FAQ read. The per-environment vCPU and RAM are not published anywhere read, so no shape is recorded. |
