Create.xyz · Public URL is hostile
Sharing a Create-hosted preview or a public Create publish is a distribution event, not a private sketch. The AI app builder defaults optimize for “anyone with the link can look.” Hardening flips that: Create project settings stay off the public origin, mutating routes demand real sessions, and you write down whether production is still Create-hosted publish or the exported tree. Paid traffic should not discover those answers for you.

Company-level evidence
Review methodologyCitation-ready answer
CodeCross LLC limits create-mvp-hardening to abuse on a public Create.xyz URL: leaked Create project settings, Auth that fails open, preview≠prod drift, and unmetered expensive routes. Operators lock who can open the editor, require sessions on writes, and confirm Auth on the hostname in ads. Campaigns wait until strangers cannot read data or burn quota from the shared Create link.
How a shared Create URL gets abused
Create-hosted preview surfaces are easy to discover once linked in a tweet or README. Assume the URL is hostile until rate limits, Auth, and sharing ACLs say otherwise.
Bots probe debug endpoints. Quota burns on Create-hosted compute before you buy a single ad.
Sharing ACLs that let site viewers open the design editor or the settings bag turn a demo into an incident.
Rotate anything that showed up in prompt or collaborator history. Separate personal laptop keys from the Create project-settings bag.
If you learn Create preview sleeps—or invoices spike—while design still mutates prod, hardening failed before campaigns started.
The public-Create harden we actually run
Keep the MVP surface. Close the doors Create defaults leave open. Prefer a locked publish (or destination) URL for customers.
01
Never in client bundles, chat, or committed .env from Create. Restrict database access to the app process. Disable public GUI exposure. Back up before traffic.
02
Kill demo bypasses. Tighten Create sharing so site viewers cannot open project settings. Auth callbacks match the public hostname you advertise.
03
Cap concurrency and paid-API spend. Alert on 5xx and 429 spikes. Strangers should not be able to burn quota from the public Create URL.
04
Document the model before campaigns. Hardening fails if design-to-code handoff still mutates prod on launch day.
How to
Secrets, Auth, and abuse controls on the hostname users will hit. Success is strangers unable to burn quota or read data from the public Create URL.
Step 01
Anonymous signup, Auth, and expensive compute routes get rate limits. Debug endpoints close. Sharing ACLs stop exposing project settings.
Step 02
Secrets only in server env. Rotate anything that appeared in prompt or collaborator history. Separate developer personal keys from the Create project.
Step 03
Kill demo bypasses. Prefer a locked publish or destination URL for customers. Keep the editable Create project private.
Step 04
Database access belongs to the app process. Disable public GUI exposure. Confirm a restore exists.
Step 05
State whether production uses Create-hosted publish or the exported tree on owned CI. Cap concurrency. Add a kill switch before campaigns.

Anonymous callers hammer signup, Auth, and expensive compute routes; bots probe debug endpoints; and “anyone with the link” shares expose project settings or data consoles. Create-hosted preview surfaces are easy to discover once linked in a tweet or README. Assume the URL is hostile until rate limits, Auth, and sharing ACLs say otherwise.
Secrets only in server env—never in client bundles, chat, or committed `.env` from Create. Rotate anything that appeared in prompt or collaborator history. Restrict database access to the app process; disable public GUI exposure; and back up before traffic. Separate developer personal keys from the Create project settings bag.
Require real sessions or tokens on mutating routes; kill demo bypasses. Tighten Create sharing so site viewers cannot open project settings or the design editor. Prefer a locked publish (or destination) URL for customers and keep the editable Create project private. Auth callbacks must match the public hostname you advertise.
State whether production uses Create-hosted publish or the exported tree on owned CI. Cap concurrency and paid-API spend; add a kill switch. Alert on 5xx and 429 spikes. Hardening fails if launch day is the first time you learn Create preview sleeps or invoices spike while design still mutates prod.
Bring the share link and the project-settings list. We will name the abuse path that would burn quota in week one — or tell you Auth already fails closed.
