00 /SERVICE · FIX
Senior engineers diagnose root cause and ship a fix in days, not weeks. Fixed-price scopes, bylined work, written summary on every engagement. Money-back if a sprint cannot resolve the issue.
Short answer
Last reviewed · 2026-05-02
Fixing a broken base44 app with Base44Devs follows three productized tiers. A $497 diagnostic audit is delivered in one business day and produces a written root-cause report with reproduction steps and a prioritised remediation plan. A $1,500 bug-fix sprint resolves a single high-impact issue inside 48-72 hours and is money-back if the issue cannot be resolved. A $3,000 complex multi-bug rescue handles backlogs of 3-8 related defects in 1-2 weeks. Every engagement ships with a regression test plan and a written summary that names the root cause and the change. Base44Devs has shipped or debugged 100+ base44 apps in production across 29 documented failure categories.

02 /METHOD
Four stages, every fix, regardless of category. The reproduce gate is what makes the work shippable — and refundable when it is not.
01/STEP
We read the stack trace, the network log, and the credit-burn graph. We walk every layer. We do not guess. We isolate the failure to a specific line, function, or schema mismatch before any code is written.
02/STEP
We reproduce the failure deterministically — same input, same broken output, every time. If we cannot reproduce it, we cannot prove we fixed it. This step is the gate; nothing ships without a written 100% reproduction recipe.
03/STEP
Smallest possible change at the correct layer. No drive-by refactors, no AI rewrites of files we did not touch. The patch is reviewed against the reproduction recipe and shipped behind a feature flag where the platform allows.
04/STEP
Tests pass. The original failure cannot be reproduced. Credit-burn delta is recorded. The fix is documented in a written summary that names the root cause, the change, and the verification steps. Then — and only then — we close the ticket.

03 /DIY VS. HIRE
The honest answer depends on the bug. The agent is genuinely good at some classes of issue and a credit-burn trap on others. The decision matrix below is what we use ourselves.

06 /FAQ
Diagnostic audits start within one business day of payment confirmation. Bug-fix sprints typically begin within 48 hours. We work in your time zone for cutover-sensitive fixes.
If the root cause is a platform bug we cannot work around, we deliver a full diagnostic with reproduction steps, file the report with base44 / Wix support on your behalf, and refund the sprint fee. The audit fee covers the time to find that out and is itself credited against any subsequent engagement.
Yes. We can be added as a collaborator on your workspace, work in a forked branch, or operate from screen-shares only — whichever your security policy permits. We never log in to third-party services on your behalf without explicit permission for each one.
Yes — that is what the Complex Multi-Bug Fix tier ($3,000, 1-2 weeks) is for. We triage, prioritise by impact, and ship fixes in a single sprint with a written summary. Up to 8 related defects per engagement.
We deliver every fix with a regression test plan and document any platform behaviours we relied on. If a future update breaks the fix within 90 days of delivery, we re-engage at no charge. After 90 days, we re-engage at a discounted rate.
If the bug is a UI layout issue, a copy change, or a single-step workflow tweak, the AI agent will usually solve it inside 5-15 credits. If the bug involves auth, payments, RLS, webhooks, schema migrations, or has survived three or more agent attempts, the agent is more likely to make it worse than fix it. The decision matrix in section 03 spells out the full rule.
Wiz disclosed a critical SSO bypass and Imperva published parallel findings on JWT leakage and stored XSS in July 2025. If your app used base44's SSO-only access mode at any point before late July 2025, audit your user list for accounts whose email domain is outside your SSO allowlist and rotate any third-party API keys held during the window. Our audit checks the post-disclosure remediation as one of the 110 standard checks.
A written checklist with one row per fixed defect. Each row contains: the original failure trigger, the input that reproduces it (or its absence post-fix), the expected versus actual output, and the SDK call or UI step that exercises it. The plan is rerun on any future platform update so a regression is caught before users notice.
