Auth leaks
Users can access data that does not belong to them.
Charcoal Labs helps founders harden AI-built apps before launch - auth, database, payments, APIs, LLM costs, observability, deployment, and production risks.
Built for founders using Cursor, Lovable, Bolt, Replit, v0, Claude Code, Supabase, Firebase, Stripe, Razorpay, OpenAI, and modern AI coding tools.

The launch gap
AI coding tools are excellent at generating screens, flows, APIs, and prototypes. But production apps fail in boring places: permissions, webhooks, database rules, rate limits, background jobs, secrets, logs, retries, and cost controls.
Users can access data that does not belong to them.
Stripe or Razorpay webhooks fail silently or process twice.
Missing indexes, weak migrations, unsafe schema decisions.
Every user action calls expensive models without limits.
Errors happen, but nobody knows until customers complain.
No staging, rollback plan, smoke tests, or incident process.
This is for the moment after the demo works and before real customers, real payments, and real production incidents arrive.
You used Cursor, Lovable, Bolt, Replit, v0, or Claude Code to build fast. Now you need to know what is unsafe before real users arrive.
Your product works, but launch risks are scattered across auth, payments, database, APIs, and AI usage.
You build client apps quickly, but need a repeatable launch-readiness system before handoff.
You can build, but you want a second brain/checklist for production risks before launch.
A practical production-readiness system for AI-built apps.
A founder-friendly checklist covering the most common production risks in AI-built apps.

Run an AuditLimited human-reviewed sprint for founders who need hands-on hardening before launch.
Apply for SprintThe checklist is intentionally boring: the work real products need when demo traffic turns into production usage.
check
Ownership checks, admin routes, RBAC, tenant isolation, session handling, OAuth edge cases.
check
Schema risks, indexes, migrations, backups, soft deletes, data consistency.
check
Stripe/Razorpay webhooks, idempotency, retries, failed payments, refunds, subscription state.
check
Validation, rate limits, pagination, CORS, file uploads, unsafe endpoints.
check
Per-user cost tracking, prompt versioning, fallback models, abuse limits, budget caps.

Error tracking, structured logs, alerts, slow queries, launch dashboards.

What happens when payments fail, AI calls timeout, jobs retry, or the database slows down.
Charcoal Labs is built for one specific moment: when a founder has moved fast with AI and now needs production discipline before launch.
01
Use the free checklist or submit your app for a production-readiness report.
02
Follow the Production Kit or use the Rescue Sprint for hands-on help.
03
Add observability, cost controls, rollback plans, and incident checklists before real users arrive.
Start with the free checklist, then use stack-specific checks when the risk is real.
The funnel starts without a call. Choose the level of evidence and help your launch needs.
