Bolt runs your whole build in a browser-based WebContainer, which is why the preview feels instant and finished. It's also why the thing that works perfectly inside that sandbox can behave differently the moment it leaves it. This is fixable, usually without a rebuild.
It ran perfectly in the Bolt preview, and then broke the moment you deployed it somewhere real.
02
Your environment variables and secrets were fine inside the WebContainer and now nothing can find them in production.
03
The database connection that worked in Bolt's sandbox doesn't behave the same way against your actual hosting.
04
Real users have arrived and things are slowing down or falling over.
05
An investor or client just asked for a technical due-diligence review, and you don't know what to show them.
06
You've been quoted a five-figure rebuild, and the people quoting it made you feel foolish for asking.
How it works
We take it over, rather than start again.
We start with a fixed-price production audit: $7,500, one week. For a Bolt-built app that means tracing exactly what changes between the in-browser WebContainer and your real deployment target: database wiring, environment variables, build output and hosting configuration. You get a written specification: every fix as a module with acceptance criteria and its own fixed price. Keep what deserves to live; replace only what doesn’t.
→
No judgement. Sandbox-to-production gaps catch out every WebContainer-based tool.
→
No lock-in. You own the code, the design and the spec, always.
→
No open-ended bills. Every number is fixed before we start.
Ongoing
And afterwards, if you want: Maintain.
Monitoring, patching, model migrations and evals with a named monthly report, from $1,500/month. Your app stays shipped.
