Rocket.new · Public Launch URL is hostile
A public Rocket.new staging or production Launch URL invites scrapers, leaked connector keys, and unreviewed Chat/Visual edit diffs as soon as you share it. Hardening a Next.js or Flutter Build means sealing secrets out of shared Context, requiring review before changes hit the live Launch, locking who can Launch production, and capping credit-backed API burn—before paid traffic treats the MVP as free infrastructure. You keep the surface Rocket generated; you close the abuse doors Launch defaults leave open.

Review methodologyCitation-ready answer
CodeCross LLC limits rocket-mvp-hardening to abuse on a public Staging or Production Launch URL: leaked Stripe keys in shared Context, missing RLS on generated Supabase tables, world-visible task links, and Build-credit burn. Teams lock who can Launch Production, require sessions on writes, and cap connector spend. Campaigns wait until a stranger cannot drain credits or read rows from the shared Launch link.
How a shared Launch URL gets abused
Rocket Staging URLs are easy to discover once tweeted. Assume the URL is hostile until Auth, RLS, and credit caps say otherwise.
Public endpoints that call paid connectors consume Rocket credits and vendor quota before you buy a single ad.
Chat threads, collaborator history, and committed configs Build wrote turn a demo into an incident.
Tables the schema generator created are readable to anyone who finds the Staging URL unless you enforce row rules under org credentials.
If you learn Staging env was still serving buyers—or credits spiked—while Chat still mutated prod, hardening failed before campaigns started.
The public-Launch harden we actually run
Keep the MVP surface. Close the doors Launch defaults leave open. Prefer a locked Production hostname for customers.
01
Never in Chat, shared Context exports, or committed `.env` with real keys. Rotate anything that appeared in workspace history.
02
Kill demo bypasses. Prefer a locked Production custom domain for customers and keep Staging for internal QA. Auth callbacks match the hostname you advertise.
03
Cap concurrency and Build-credit spend. Alert on 5xx and spend spikes. Strangers should not burn quota from a public Launch URL.
04
Document the model before campaigns. Require protected main if GitHub Sync is live. Hardening fails if Chat still mutates prod on launch day.
How to
Visibility, env tabs, RLS, and credit controls on the hostname users will hit. Success is strangers unable to burn credits or read data from the public Launch URL.
Step 01
Anonymous Stripe, AI, and email routes get rate limits. Shared task invites stop exposing editor rights. Prefer private Staging.
Step 02
Secrets only in Environment tabs or destination vault. Rotate anything that appeared in Chat or collaborator history. Separate personal Stripe keys from the production bag.
Step 03
Kill demo bypasses. Auth callbacks and Stripe webhooks must match the public hostname you advertise—not a personal Staging link.
Step 04
Task visibility stays private for editable work. Share only locked Staging or Production URLs intentionally.
Step 05
State whether production uses Rocket Production Launch on Netlify or ZIP/GitHub on owned CI. Cap connector spend and Rocket credits. Add a kill switch before campaigns.

Shared Launch links are easy to discover once tweeted; bots probe Auth and write paths against generated schemas; anonymous callers hammer Stripe, AI, or email connectors the Build wired without rate limits. Prefer private staging and a locked production hostname. Assume every public Launch URL is hostile until Auth, RLS, and rate limits say otherwise.
Secrets only in host env or vault—never in Chat threads, shared Context exports, or committed configs Build wrote. Rotate anything that appeared in workspace history. Enforce RLS (or equivalent) on every table the schema generator created. Separate developer personal connector accounts from the production bag so a workspace leak is not a prod leak.
Public endpoints that call paid AI, email, or payment connectors consume Rocket credits and vendor quota when unauthenticated callers spam them. Cap expensive routes, add a kill switch, and alert on anomalous 5xx and spend spikes. Hardening fails if launch day is the first time you learn Chat left debug Auth open on a public Launch.
Write the choice before ads: Rocket Production Launch on Netlify is simpler and more locked-in; org-Git CI from GitHub Sync or ZIP gives rollback and a second-engineer promote. Require protected main if Sync is live. Kill “Launch whatever Chat just produced” onto the advertised hostname. Mark Staging Launch non-prod so on-call does not learn the model mid-campaign.
Bring the share link and the connector list. We will name the abuse path that would burn credits in week one — or tell you RLS already fails closed.
