What actually breaks in production Lovable apps
We've rescued ~12 Lovable-started SaaS apps in 2026. Three failure modes account for >80% of them:
- Database query patterns that don't scale. Lovable generates N+1 query loops in React components without realizing it. Works fine at 10 rows; breaks at 1000. Missing Supabase indexes on foreign keys + RLS policies that re-execute on every nested query compound the problem. We fix by adding indexes, batching queries via Supabase RPC, and moving hot reads to server components with caching.
- Auth state that leaks across concurrent users. Lovable-generated client-side auth often uses module-level state that shouldn't be there. Two users hit the same Vercel serverless instance during a cold start, they sometimes see each other's data. We fix by moving auth resolution to per-request server functions and clearing the module state pattern entirely.
- Third-party API rate limits hit from inefficient polling. Stripe, Resend, OpenAI, and Supabase Realtime all have rate limits. Lovable apps tend to poll instead of subscribing, which kills you at 100+ concurrent users. We fix by replacing polling with webhooks (Stripe), Resend audiences (email), background queues (OpenAI), and proper Realtime channels (Supabase).
What our rescue process looks like
- Day 1: Triage. You give us repo access (read-only is fine). We run our diagnostic checklist — 47 production failure points specific to Lovable apps — and write up exactly what's broken and why.
- Day 2: Quote. You get three fixed-price options: hotfix ($999-2,500 to unblock you in 48 hours), module refactor ($2,500-5,000 for one subsystem), or full rebuild on existing schema ($5,000-15,000 for production-ready hardening).
- Day 3-21: Build. Daily standup updates via Telegram or email. We work in your repo on a branch, ship PRs with clear commit messages, and run load tests before merging. You see every change as it happens.
- Day 21+: Handoff. Final delivery includes a 30-min screen-share walkthrough of what changed and why, plus a written runbook for the new patterns. You own the code; we leave clean.
What we charge
- Hotfix — $999-2,500. Single-component breakage, urgent auth bug, broken integration repair. Delivered in 48 hours.
- Module refactor — $2,500-5,000. Rebuild one subsystem (checkout flow, admin dashboard, real-time feature) to production patterns. 1-2 weeks.
- Full rebuild on existing schema — $5,000-15,000. Production-harden the entire frontend and business logic against the same Supabase database. Users keep their accounts; app scales to 10K+ DAU. 2-3 weeks.
- Ongoing maintenance — $1,500/month. Bug fixes, feature additions, dependency updates on a maintenance contract. Cancel anytime.
When NOT to hire us
Be honest with yourself before reaching out — these are bad fits:
- You haven't tried Lovable yet and want us to build from scratch. Try Lovable first (it's free) — most of what we do is fix things, not generate them. Lovable can ship your first version in a weekend.
- Your app needs HIPAA, SOC 2, or financial regulatory compliance. Outside our wheelhouse — hire a specialized agency.
- You're building an NFT marketplace, on-chain game, or crypto wallet. We've turned down 6 of these in 2026; the smart-contract attack surface is not something we want to be responsible for.
- You want us to commit to a 6-month engagement. We do fixed-price project work, not retainers (except $1,500/mo maintenance after a successful rescue).
