[Talk to us about your Bolt app](https://zeroic.in/book?service=code-rescue) [See the work](https://zeroic.in/work) **Starting at** $6,000 **Timeline** 2-4 weeks **Products shipped** 40+ ## Where most Bolt apps are Bolt is the quickest way to get an idea running in the browser. Growing it is harder: keys end up in the frontend bundle, routes trust whatever the browser sends, and each prompt adds another copy of the logic. We fix what is failing and keep the product you've already shown people. API keys sitting in the frontend bundle → Secrets moved server-side and rotated Routes trust the user ID they are sent → Every route checks who is asking The same logic copied across files → Shared logic in one place, with tests Every fix burns more tokens → Changes you can make without prompting ## What we fix in Bolt apps ### Keys out of the browser Anything behind a VITE_ prefix is compiled into the JavaScript every visitor downloads. We move OpenAI, Stripe and Supabase secrets to the server and rotate any that leaked. ### Routes that check the session A route that reads a user ID from the request body lets any signed-in user open someone else's data. We tie every request to the session and check who owns the record. ### One copy of the logic Prompted fixes often copy the same rule into several files, so a change in one place misses the others. We pull each rule into one module and put tests around it. ### Out of the editor, onto real hosting Bolt projects can be exported or pushed to GitHub. We set up proper hosting, separate environments and repeatable deploys, so releases stop depending on the editor. ## How it works 1. 01 ### Review (3 days) We read the code, the database and the deploy setup, and tell you plainly what to keep, what to fix first and what the fix costs. 2. 02 ### Fix what is failing Senior engineers move secrets server-side, lock every route to the session and untangle the logic, keeping your screens. 3. 03 ### Harden and hand off Tests, monitoring and docs go in before handover. You own the code and every account, with 6 weeks of support under real load. Starting at $6,000 Fixed scope and fixed price, agreed after the 3-day review. Not sure what is wrong yet?

Code Rescue starts at $6,000 for a fixed scope, agreed after a 3-day review. You know the full price before any work starts, and we always take the cheapest route to production. Not sure yet? A Security Audit, from $1,000, shows what needs fixing first. Is my Bolt app safe to launch? It will be once the bundle is checked. Keys behind a VITE_ prefix end up in the JavaScript every visitor downloads, where anyone can copy them. A Security Audit finds these in 1-2 weeks. Do you fix apps on Bolt Cloud too? Yes. Bolt Cloud adds built-in auth, databases and storage, which closes some gaps for new projects. Access rules, ownership checks and tests still need a senior review before launch. Will you rebuild it from scratch? Rarely. When the data model is sound we fix forward. When logic and secrets run through the frontend, we keep your product logic and screens and replace only the layer underneath. Do we own the code afterwards? Yes, 100%. You own the code, database, docs and credentials. No lock-in and no proprietary platform. ## Hear from us within 24 hours. **Prashant and Khushi** Partners @ Zeroic Bolt app hitting its limits?
