Forty paying customers signed up by Friday. Then the launch tweet hit Saturday lunchtime. The StackBlitz preview tab crashed because it wasn’t a real deploy. Customers saw a blank screen. He had no CI, no monitoring, no deploy target outside the Bolt sandbox.
Rescue Bolt.new code audit · security review · production-readiness · UK
A Bolt.new code audit for the app that’s leaking keys. burning tokens, breaking on Netlify.
Your Bolt.new app shipped. It worked in the WebContainer preview. Now on Netlify, auth fails under concurrent users, the OpenAI key in the client bundle got scraped within hours, and the “Try to Fix” loop is burning 100k tokens per retry patching symptoms. In seven days, two senior engineers audit your Bolt project the way a senior hire would on day one, then hand you a ranked fix list and a hardened path off StackBlitz.

Eshan built his MVP in a weekend. The preview tab looked great. The launch tweet broke it.
The freelance senior he’d hired had no commit history he could walk through. The seed lead asked one question: “Has anyone independent looked at this yet?” He couldn’t answer it.
We ran the audit. Found twelve things, three critical: no production deploy target, secrets in the public Bolt repo, no rate limit on auth. He had the written report on day eight. This page is for founders who’d rather know what’s in their Bolt.new codebase before the seed lead does.
The finding. The severity we file it under.
Patterns we’ve seen across nine independent Bolt.new audits. You can’t blame the tool. You can fix the gaps before someone else finds them.
- 01
“Customers see an iframe-hosted preview, not your domain.”
Real deploy target on Netlify Functions, then AWS. No PCI, no SOC-2, no real DNS until you ship off the sandbox. We stand up a hardened deploy in week one.
- 02
“Stripe, OpenAI, and SendGrid keys live in a public share link.”
Secret-scan report + rotation plan. Every credential found in repo and Git history. Rotation is the only fix, and we map it key by key.
- 03
“No idempotency key on the handler. Customers charged twice during retry storms.”
Idempotency keys on every write. Duplicate deliveries return the original response. Refunds stop being a manual job.
- 04
“Who changed what, when, why? No record.”
Append-only audit log on every mutation. The SOC-2 audit stops being a six-month panic. The record exists from the first write.
- 05
“Full name, email, billing address loaded into the React state, visible in dev tools.”
Server-side scoping + minimal payloads. Only the data a screen needs reaches the browser. The rest stays behind the API.
- 06
“Customer-list queries take 14 seconds at 5K records. At 50K they time out.”
Index plan + query review. Today it’s fine. In three months it’s an outage. We catch it before it’s on-call at 2am.
- 07
“Stripe live key in a plain-text .env that’s in Git history.”
History purge + secrets manager. Git blame says “Bolt.new”. We rotate, purge history, and move every credential into a managed store.
- 08
“Login and signup accept unlimited requests. Brute force is possible.”
Per-IP + per-account rate limits. Anomaly alerts wired to Slack. The endpoints stop being an open door.
- 09
“No unit tests, no integration tests, no e2e. Every refactor is a leap of faith.”
Coverage report + a first test harness. Playwright e2e on the critical paths first, so the next change isn’t a gamble.
- 10
“The first enterprise customer asks for a security questionnaire and a DPA. You have neither.”
Readiness checklist + signed DPA template. The deal stops stalling. You hand over evidence instead of an apology.

Evidence your first enterprise customer asks for, handed to you
so the questionnaire takes two hours, not two months.
OWASP Top-10 pen test summary
Every category tested against your live Bolt.new app. Pass or fail per row. Sample attack plus remediation per failure.
Severity-ranked fix list
Critical, high, medium, low. Effort estimate per fix in GBP and engineering days. 14 days to safe, 6 weeks to enterprise-ready.
SOC-2 readiness checklist
Every control assessed: audit log, RBAC, encryption, MFA, change management. A gap list and an 8-12 week path to ready.
UK GDPR + DPA pack
Signed DPA template. Sub-processor list. Data-flow diagram and ROPA. A one-page architecture diagram with six suggested ADRs.
Architecture + scale model
Schema review, data-flow diagram, webhook reliability check, and a load model at 10× your current traffic.
Hardened deploy path off StackBlitz
A real deploy target on Netlify Functions, then AWS. CI/CD pipeline review and a tested deploy-rollback path.

Forty paying customers signed up by Friday. The launch tweet broke the preview tab on Saturday. The audit found the things I couldn’t see, and I had the report on day eight.
Three ways to start. The audit fee is fixed.
Everything else is line-itemed. You walk away with the report whichever path you pick.
7-day audit
£8K fixed. A 30-page written report with a severity-ranked fix list and effort estimate per fix.
- OWASP-grade pen test
- Architecture + scale model
- SOC-2 + DPA pack
- No commitment to fix with us
+ fix sprint
£18K-30K total. We fix the critical findings behind a flag. You keep Bolt.new for the rest.
- Audit + 4 critical fixes
- Idempotent billing
- Auth + RLS hardened
- Audit log on every mutation
+ rebuild
£28K-60K total. Full rebuild on MERN + AWS. Same Bolt.new UI, a new defensible spine, zero-downtime cutover.

- Acquirer-ready ADRs
- 30-day walk-away both ways
- IP assigns on every commit
What founders actually ask about the audit
Pain-first, soft-second.
The honest answer: probably not yet, and that’s normal. Across 9 Bolt.new audits, every codebase had at least three critical findings: an auth gap, a billing race condition, a tenant-isolation hole, or a missing audit log. Bolt.new is a brilliant builder. It’s not a security platform. The Bolt.new code audit tells you what’s missing, ranked by severity, with effort estimates.
No. Every founder we audit shipped fast with the tools that worked. We’re not judging your speed. We’re telling you what to fix before someone else finds it. The report is written for you, not against you. We’ve never named-and-shamed a client and we never will.
Seven days of senior engineering attention on your codebase. An OWASP-grade penetration test against your live Bolt.new app. Architecture review. A load model at 10× current traffic. SOC-2 readiness checklist. UK GDPR + DPA pack. A code quality and test coverage report. A 30-page written report with severity-ranked findings, sample code per finding, and effort estimates in GBP and engineering days. You can walk away after the audit. Most founders don’t, but the option is real.
No. The audit runs against a staging copy of your codebase and a separate environment for penetration testing. Your production stays untouched. Your customers don’t see a thing.
Yes. The report is written so your engineer can fix the findings without us. Every finding has sample code, an effort estimate, and a recommended pattern. About a third of our audited clients fix in-house, a third use us for the critical fixes only, and a third move to a full rebuild. All three paths are fine. You decide on day eight.
For most cases, yes. The audit doubles as a diligence pack: architecture diagram, six suggested ADRs, threat model, sub-processor list, SOC-2 readiness checklist, DPA template. Seed leads have read it on Friday and approved on Monday. Enterprise customers have used it to skip 70% of their security questionnaire. Full SOC-2 certification is a separate 8-12 week paperwork phase; we hand you the path.
Yes, before anything else. NDA signed inside 30 minutes via DocuSign. We only need read-only repo access for the audit, never write access. Findings are encrypted at rest, accessible only to the engineers on your project, and destroyed 90 days after handover unless you request a longer retention.
Bolt.new is the builder. We’re an independent auditor. The audit you get from us is the one your acquirer’s CTO trusts because it isn’t coming from the company that built the tool. Our pen test goes against your live app, the dependencies you imported, the integrations you wired in, and the deploy infrastructure you chose. Different angle. Different findings.
