Chainweb provides rapid bug fixing and expert code review to stabilise your web or mobile app and get you back to shipping.
Most teams call us when something is already on fire. We are used to it.
Production issue
Something is broken right now?
Send us your issue list or repository access. You get a triage assessment the same day and a fix plan within 24 to 48 hours.
Three ways in, depending on how urgent it is.
Urgent production issues
Something is broken in production and it cannot wait for a sprint.
- Hourly rate or fixed price per issue
- Fast start, no long-term commitment
- Triage the same day you send it
Stabilization sprint
The same issues keep coming back and nobody has time to find out why.
- Fixed scope, agreed before we start
- Weekly progress you can check, not a report at the end
- Ends with a codebase your team can work in again
Ongoing support
A live product that ships regularly and needs someone accountable when it breaks.
- Monthly retainer or hourly allocation
- Agreed response times, out of hours if needed
- We stay familiar with your codebase instead of relearning it
Find the one that sounds like your week.
"Users can't check out and we are losing sales every hour."
Critical bug fixing
We investigate and fix the bugs that cost you users or money, starting with the one bleeding right now.
Root cause explained, fix as a clean pull request, steps to verify it yourself.
"Everything got slow and nobody knows when it started."
Performance & stability
We measure before we touch anything, so you find out what is actually slow instead of guessing.
Before and after metrics, so the improvement is measurable rather than felt.
"Nobody on the team wants to touch that part of the code."
Code review & refactoring
We audit the codebase and turn the scary parts into something your team can work in again.
A refactor roadmap ranked by risk and effort, and the option for us to implement it.
"We fix one thing and two others break."
Regression protection
We add tests exactly where they stop that from happening, not everywhere for the sake of coverage.
The same bug not coming back three weeks later.
Why Chainweb
-
Senior debugging, not guesswork
Our engineers bring 7–10+ years of hands-on production experience. They’ve debugged live systems under real load, deadlines, and business pressure which means faster diagnosis and fewer mistakes. -
Fast turnaround with clear communication
We respond quickly and keep you informed at every step. Initial response within 1–3 business hours, clear status updates, and no silent periods where you’re left guessing what’s happening. -
Security-aware fixes (OWASP/NIST mindset)
Every fix is reviewed through a security lens.
We follow OWASP and NIST best practices to avoid introducing new vulnerabilities while resolving existing issues, especially in auth, data handling, and APIs. -
We leave your codebase better than we found it
We don’t just fix bugs, we improve maintainability. Cleaner logic, safer patterns, clearer structure, and documentation where it matters, so future changes become easier instead of riskier.
FAQ
Common Questions
Bug Fixing & Code Review
Your team is probably already using AI to write and fix code. The question is not whether to use it. It is what it is allowed to touch, and who is responsible when it gets something wrong.
An agent that knows your architecture and conventions, handling recurring fixes, tests, logging and dependency updates. Not a generic assistant guessing at your code.
It cannot merge without a human, touch payments or auth unreviewed, read your secrets, or follow instructions hidden in an issue comment.
Your code is covered by an agreement with a company, not the terms of service of a tool someone signed up for. Permissions and prompt injection defence configured properly.
Sometimes the bug is the symptom, not the problem.
Was that bug actually a vulnerability?
Penetration testing and security assessment, from €900, to find what else is exposed.

When a module costs more to maintain than to replace, we tell you and we build the replacement.
Learn more →The problem is manual work, not code?
Some bugs are people copying data between systems. That gets automated, not debugged.
