00 /SERVICE · FIX
For teams whose Base44 app is broken in production. A senior engineer finds the root cause, ships the fix and documents the change. A $1,500 fix sprint covers one issue: it starts within 48 hours and ships 48–72 hours after kickoff. A $3,000 rescue covers 3–8 related bugs. Fixed price, and a refund if we don't fix it.

Short answer
Last reviewed · 2026-09-24
Fixing a broken base44 app with Base44Devs costs a fixed $497 to $3,000. A $1,500 bug-fix sprint resolves one high-impact issue: it starts within 48 hours of payment and access and ships 48–72 hours after kickoff, with money-back if it cannot resolve the issue and a 90-day fix hold after. A $3,000 multi-bug rescue resolves 3–8 related defects in 1–2 weeks. When the cause is unknown, a $497 diagnostic audit delivers a written root-cause report one business day after access. Every fix ships with a regression test plan and a written summary that names the root cause and the change. The team has shipped or debugged 100+ base44 apps in production, and the fix index documents 47 failure playbooks across 11 categories. When repeat fixes stop paying off, the migration ROI calculator estimates when leaving base44 pays back.

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. If it lands on hire, our Base44 developer hiring guide compares every engagement shape.

06 /FAQ
A fixed $1,500 for one high-impact issue (the bug-fix sprint), or $3,000 for 3–8 related defects (the multi-bug rescue). When the cause is unknown, a $497 diagnostic audit finds it first. Every price is quoted in writing before work starts, and production-down work is billed at the same prices as scheduled work.
Money-back if the sprint cannot resolve the issue, including a Base44 platform bug with no workaround. If a Base44 update breaks the fix within 90 days, we re-fix it at no charge. "Resolved" means the original failure no longer reproduces from the written reproduction recipe we build before any code changes (step 02 of the method). If the root cause is a Base44 platform bug with no workaround, you also get the full diagnostic with reproduction steps, and we file the report with Base44 support for you. On the $3,000 multi-bug rescue: Any agreed defect we cannot resolve is refunded pro rata. Every fix carries the 90-day fix hold.
A bug-fix sprint starts within 48 hours of payment and workspace access and ships 48–72 hours after kickoff. A multi-bug rescue runs 1–2 weeks. A diagnostic audit is delivered 1 business day after access (2 for apps with 15+ tables or multiple integrations). Production-down requests (payments, auth, or an unreachable app) follow the urgent terms: Acknowledged inside two business hours (9am-6pm Eastern, Mon-Fri). Same prices as scheduled work — no urgent surcharge. Three urgent slots held every week.
If a Base44 update breaks the fix within 90 days, we re-fix it at no charge. That 90-day fix hold covers every sprint and rescue. Each fix also ships with a regression test plan that records the platform behaviours it relies on, so an update that breaks it is caught before users notice. After 90 days, a new break is quoted as a new fixed-price sprint; clients on the $2,000/month care plan get a monthly regression check after Base44 updates.
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.
If the bug is a UI layout issue, a copy change, or a single-step workflow tweak, try the AI agent first: those are the bug classes it handles well, and a failed attempt costs little. 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 (July 2025) and Imperva (published August 2025) disclosed separate Base44 platform flaws. Wiz found that outsiders could register on private, SSO-only apps with nothing but the app ID; it reported the flaw on 9 July 2025, Wix fixed it within 24 hours, and Wix found no evidence of past abuse. Imperva found an open redirect that leaked access tokens, stored XSS on app.base44.com, and the main-platform JWT being passed to user-built apps; it reported them in March 2025 and says the vendor moved quickly to fix them. If your app was private on or before 9 July 2025, review its analytics for unexpected visits and registrations in that period, as Wiz suggests, and rotate any third-party API keys the workspace held. Our audit checks the post-disclosure remediation as one of its 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.
07 /NEXT STEP
One known issue: start a $1,500 fix sprint. Several related bugs: plan a $3,000 rescue. Cause unknown: order the $497 audit, and its report names the tier that fits.
