ShipCheap
Billing risk simulator

Model the surprise-bill path before you deploy.

Pick a provider and workload shape. ShipCheap estimates how user growth, bot traffic, bandwidth, API calls, and storage can turn a cheap deploy into real spend.

Monthly bill unavailable for this setup

Firebase App Hosting requires a payment card or prepaid credits before this scenario can keep running. Attach a card in the scenario to model its metered monthly cost.

Bill duel

Same workload. Different providers. Who blows up first?

Keep the scenario fixed and pit up to 3 providers against each other on P90 bill, over-budget odds, and the cost center that spikes first.

Main risk drivers

  • Firebase App Hosting has medium listed billing risk.
  • Firebase App Hosting likely requires a billing account or card.

Controls to set first

  • Read plan limits and create a budget alert before launch.
  • Prefer a no-card path while prototyping, or set strict cloud budget alerts.

Billing incidents worth modeling

Public docs and major reporting show the risk pattern: spend controls, exposed keys, compromised credentials, bots, or metered usage growing faster than the owner notices.

Vercel

Spend controls need explicit actions

Vercel docs

Vercel's docs say spend amounts can trigger notifications, webhooks, or pausing, but project pausing must be enabled as an action.

Firebase/Gemini

Client keys can expose AI usage

Firebase docs

Firebase docs warn against adding Gemini API access to app-exposed keys and recommend App Check for serious apps.

Google/Gemini

$15.4k reported

TechRadar

TechRadar reported a case where an exposed Google API key was abused for Gemini requests before the owner could stop the spend.

AWS

$45k reported

Tom's Hardware

Tom's Hardware reported a compromised AWS account used for crypto-mining workloads that generated a large cloud bill.

These examples are cautionary references from official docs or major reporting, not predictions or provider-specific price promises.

Lower-risk alternatives

Providers with no-card paths or lower listed billing risk.

Render

Medium risk

A developer-friendly platform for web services, workers, cron jobs, static sites, and managed databases.

Koyeb

Low risk

A serverless-style app platform for containers, Git deploys, APIs, workers, and global services.

Vercel

Medium risk

A frontend-first platform with strong serverless and edge support, best known for Next.js deployments.

Supabase

Low risk

A hosted Postgres platform with auth, storage, edge functions, and realtime features.
