If your district or school filters web traffic, your IT team needs to allow Playlab through the firewall. The safest guidance is to whitelist the entire Playlab root domain rather than a single subdomain, since the product spans several subdomains.

​
What to tell IT to whitelist

Whitelist the whole playlab.ai root domain:
If your firewall requires specific subdomains rather than the root, the key ones are:
  • app.playlab.ai — the actual Playlab application
  • www.playlab.ai — marketing and landing site
  • learn.playlab.ai — docs, FAQ, and help center
Whitelisting only www.playlab.ai will leave the app itself inaccessible. That is exactly why we recommend whitelisting the full root domain.

​
Other things worth flagging to your IT team

Playlab works even if OpenAI or ChatGPT are blocked Playlab continues to work when OpenAI, ChatGPT, or other model provider domains are blocked at the network level, as long as Playlab’s own domains are explicitly whitelisted. Requests to model providers go through Playlab’s backend, not directly from the student’s browser. Inbound email from outside organizations If the district blocks inbound email from outside organizations, Playlab’s password-reset and invite emails may not reach students. The recommended workaround is rostered SSO (Clever, ClassLink, or Google) rather than email-based signup. See Single Sign On for details. Bandwidth Playlab’s bandwidth usage is modest, comparable to other web-based classroom tools. Typical district bandwidth is more than enough to support classroom use at scale.
