Cardinal ReviewGeneral
What is Cardinal Review?
A Pterodactyl 2.0 extension that tells you why a server crashed, what broke it and how to fix it. It reads the console and log files, recognises known errors with 148 rules, puts the main cause on top and turns the fix into a checklist.
Does it work with my eggs?
Yes. Monitoring, the health score and the AI work on any server. The rule packs cover Minecraft, proxies, modded servers, Node.js and Python apps, Discord bots, Steam and SRCDS games, databases and Pterodactyl itself. Try your own log in the live demo.
Does it slow down my servers?
No. Monitoring reads the stats your panel already has, once a minute per server, from the panel's own scheduler. Nothing is installed inside your game servers.
Does it work on Pterodactyl 1.x?
No. It needs the extension system of Pterodactyl Panel 2.0.
Can subusers use it?
Yes. Give them ext.cardinal-review.view per server. The AI has its own permission, ext.cardinal-review.ai.
Do I need an AI key?
No. Log analysis, monitoring, the health score and console alerts work without one. A key is only needed for the AI assistant in the full edition, and it's your own key with Gemini, ChatGPT, Claude or Kimi.
Lite, full edition and Pro
Is Lite really free forever?
Yes. No trial, no time limit and no license key. It's updated less often than the full edition, but it never stops working.
What does the full edition add?
The health score breakdown, the Logs tab (latest.log, crash reports, JVM error files, pasted or uploaded logs), the Performance tab with lag and spike detection and incidents, the AI assistant, and every release as it ships. See pricing.
How do I upgrade from Lite?
Install the full Cardinal Review file over Lite in Admin › Extensions. They share the same id, so settings and history stay. Guide.
Do I need the Pro Addon?
No. Cardinal Review finds and explains problems on its own. Pro adds "Fix it for me" with undo, plugin downloads and updates, the server check and the config tools. It needs the full edition.
Is there a license key?
No. Installing the file is enough.
What can I do with a license?
Paid products follow the BuiltByBit Standard EULA: use them on all of your own projects, commercially too, and modify them. No reselling, sharing or redistribution, and the attribution stays unless you buy the attribution-free addon ($12.99).
How long does a license last?
Cardinal Review: $6.98 for 6 months, $9.97 in total for a year, $13.97 in total for lifetime. Pro Addon: $7.99 for a year, lifetime upgrade $4.99.
Cardinal Reporter and Bug Hunter rewards
What is Cardinal Reporter?
A free plugin for Spigot, Paper and Folia (Minecraft 1.18+, Java 17+) that checks errors against the same 148 rules on your server. Errors no rule recognises can be shared, cleaned and encrypted, with Cardinal Cloud, where they become new rules for everyone.
How do the rewards work?
Run Reporter with /cardinal consent auto. Automatic reports of errors no rule knows yet count: 3 earn Cardinal Review for 6 months, 5 for a year, 10 earn lifetime Cardinal Review and the Pro Addon. /cardinal status shows your count.
How do I claim a reward?
Open a ticket on our Discord with your Reporter ID from /cardinal status. We check the count against the reports and send the license to your BuiltByBit account.
What doesn't count?
Reports sent by hand, reports with only known errors, and errors made on purpose (test plugins, forced exceptions, edited logs). One person, one reward per tier, however many servers they run.
Does it work on Folia?
Yes. The same jar runs on Spigot, Paper and Folia. All its work runs on one low-priority background thread, never on a tick or region thread.
Privacy and security
What leaves my server when I share an error?
Only errors no rule explains, and only if you chose auto or manual. Before a report leaves, passwords, tokens, API keys, webhooks, private keys, e-mail and IP addresses, host names, player names, UUIDs and chat are removed. The report is encrypted (AES-256-GCM, key locked with RSA-OAEP) so the collector stores reports it can't read itself. /cardinal preview shows a report before it's sent.
Does the live demo upload my log?
No. The demo runs the rule engine in your browser. Nothing you paste is sent to us or stored.
Does this website track me?
No cookies, no analytics, no third-party scripts or fonts, no accounts. Downloads are rate limited per address to keep the site fast for everyone.
How do I check a download is genuine?
Compare its SHA-256 with the one on the download page or in SHA256SUMS. Only download Cardinal products from this site or BuiltByBit.
Support
Where do I get help?
On our Discord: open a ticket with your panel version and the log. Please don't use reviews for support.
I found an error Cardinal doesn't know.
Share it from the panel (Cardinal Cloud) or with Reporter's /cardinal share. Shared errors become new rules in the next update.
