We check the preview, browser console, dependencies, environment variables, Supabase setup, auth flow, deployment config, routing and hosting before recommending a fix.

Bolt.new App Not Working?
AI helped you build the app quickly. Now the preview is broken, Supabase is failing, deployment does not match local, auth does not work, or the project is stuck in a loop. We diagnose the real cause and repair the app properly.
Root Cause Diagnosis
Preview, console, build, Supabase, auth, environment and deployment checks before repair.
Repair Before Rebuild
We stabilise the existing project where repair is the right option.

Common Bolt.new
Problems We Fix
Bolt.new is useful for moving quickly, but production apps still need correct code, config, services and deployment settings.
Preview and Blank Screen Problems
Bolt.new preview not loading, blank screens after deployment, routing failures and apps that work in Bolt but break when shared.
Supabase and Auth Failures
Supabase connection errors, login not working, missing keys, bad redirect URLs, RLS problems and broken database permissions.
Deployment and Hosting Errors
Netlify or Bolt hosting deployment failures, build log errors, missing production environment variables and deploys that do not match preview.
Code and Integration Loops
API failures, repeated AI fix loops, dependency problems, broken generated logic and prompts that make the project more fragile.
Not Sure Why Your Bolt.new App Is Broken?
Guessing with more prompts can turn one fault into several. The first job is diagnosis.
Quick Answers Before You Ask for Help
We find the right layer
We can check whether the issue is Bolt.new, Supabase, Netlify, code, config or hosting.
Repair comes first
We do not recommend a rebuild unless repair is the wrong option.
Preview is not enough
We focus on getting the app stable outside the preview environment.
Plain English reporting
We explain the problem clearly so you know what changed and why.
Why Bolt.new Apps Break After the First Working Preview
A fast prototype can look finished before the production setup is actually ready.
Preview success can be misleading
- Local preview problems do not prove the deployed build is stable.
- Generated apps can miss production environment configuration.
- Build-time and runtime errors can appear only after deployment.
Connected services need checking
- Auth callbacks, secrets, domains and database policies can fail after deploy.
- Supabase, Netlify and hosting settings need technical review.
- AI fix loops can create conflicting code while trying to patch symptoms.
Stuck in a Bolt.new Fix Loop?
If every prompt creates another error, the problem probably needs diagnosis rather than more patches.
A common pattern is asking Bolt.new to fix one visible error, seeing a new error appear, then spending more tokens and time on the next symptom. The real cause may be config, architecture, dependencies, database rules or a deployment mismatch.
Human diagnosis stops that loop by tracing the failing journey from the browser to the build logs, hosting settings and connected services.
When the build log points one way and Supabase or deployment behaviour points another, trace the real failure first before asking Bolt.new for a rebuild. If the user journey around the app also needs attention, that wider flow should be reviewed after the technical fault is clear.
How We Repair Bolt.new Apps
We diagnose first, repair carefully, then test the app again in the places where it was failing.
1
Check preview and live behaviour
We compare the Bolt.new preview, shared app and live deployment so we know whether the fault is local, production-only or both.
2
Review errors and configuration
We inspect console errors, build logs, routes, Supabase, auth, environment variables, API connections and hosting settings.
3
Find the real fault
We separate code problems from config, hosting, database, dependency and platform setup problems.
4
Repair or advise safely
We repair the fault where practical, or explain when a restructure or rebuild is safer than more patching.
5
Test after repair
We retest the failing journey after changes so the app is not merely patched in one screen and broken elsewhere.
What We Check During Diagnosis
Bolt.new app failures often cross frontend, backend, database and deployment settings.
Preview behaviour
Live deployment behaviour
Console errors
Build logs
Package and dependency issues
Environment variables
Supabase URL and key setup
Auth callbacks and redirect URLs
Database and RLS issues
API keys and server functions
Netlify or Bolt hosting settings
Routing and 404 behaviour
Mobile layout where relevant
Performance and production readiness
Need a Bolt.new Developer to Take Over?
Some projects need someone technical to step in and make the app usable outside the AI builder.
We can review the project, clean up broken logic, stabilise the deployment path, repair connected services and explain what should happen next. The aim is not to criticise how the app was built. It is to protect the speed you gained from turning into avoidable rework.
Can Your Bolt.new App Be Repaired?
Repair is usually the first thing to check, but diagnosis should be honest.
Many apps can be repaired
- Small code faults, config gaps and deployment issues often have a direct fix.
Some need restructuring
- Repeated prompts can create duplicated logic, fragile routes or conflicting dependencies.
Some should be rebuilt
- If the architecture is wrong, a rebuild may cost less than patching the wrong foundation.
Diagnosis prevents wasting money on the wrong path.

Bolt.new repair FAQs
Frequently Asked Questions
Can you fix a Bolt.new app that works in preview but not after deployment?
Yes. We check the preview, live deployment, build logs, environment variables, routes, API calls and hosting setup to find why the deployed app behaves differently.
Can you fix Bolt.new Supabase problems?
Yes. We can diagnose missing Supabase keys, incorrect URLs, auth settings, redirect URLs, row-level security policies, database permissions and API connection problems.
Can you fix Bolt.new auth or login issues?
Yes. We check callbacks, cookies, route guards, Supabase auth settings, environment variables and production domains so login works outside the preview environment.
Can you fix a blank screen after deployment?
Yes. A blank screen is often caused by a runtime error, missing environment variable, routing issue, failed build asset or dependency problem. We trace the actual cause before changing code.
Do I need to rebuild my Bolt.new app?
Not always. Many Bolt.new apps can be repaired. If the architecture is too fragile, we will explain why a rebuild or restructure is safer before you spend more money.
Can you help if Bolt.new keeps creating new errors?
Yes. Repeated AI fix loops usually mean the root cause has not been found. We stop the loop by diagnosing the code, config, dependencies, database and deployment path properly.
Do you work with Netlify deployments?
Yes. We can check Netlify build commands, redirects, environment variables, routing, Supabase settings, production domains and preview-to-live differences.
Can you check whether my Bolt.new app is production ready?
Yes. We can review the app for deployment stability, auth, database access, environment variables, integrations, mobile behaviour, performance and launch risks.
