00 /SERVICE · BUILD
For founders and teams who want to hire someone to build a Base44 app instead of prompting it themselves. Senior engineers scope the app in writing, build it and hand over a code export and README: MVP $4,500, Standard $9,000, Premium $15,000. Fixed-price, with a 30-day defects warranty on every build.
Short answer
Last reviewed · 2026-09-24
A done-for-you Base44 build from Base44Devs is a fixed-price engagement that ships a production-grade Base44 app you fully own, scoped in writing before work starts. Three tiers cover the range: an MVP at $4,500 (2–4 weeks: auth, one core workflow and one Stripe Checkout path), a Standard build at $9,000 (4–6 weeks: multi-role auth, Stripe subscriptions with verified webhooks, observability), and a Premium build at $15,000 (6–10 weeks: Standard plus custom integrations, a UX pass and a migration plan). Every build includes a code export, a hand-off README and a 30-day defects warranty. Senior engineers only — no junior delegation, no offshore hand-off. The team has shipped or debugged 100+ base44 apps in production.

02 /WHAT WE BUILD
base44's sweet spot is multi-role apps with database-driven workflows and payment or webhook integrations. Below are the app types we build. Each links to a deeper solutions page.
Multi-role auth, Stripe with proration and dunning, role-scoped data, webhook reliability.
Where base44 actually shines — fast turnaround, low compliance bar, role-based access for internal staff.
Buyer + seller roles, payments with escrow, dispute flows, and webhook-driven payout schedules.
Cheap to run pre-traction, easy to refactor, with a clean off-ramp via /migrate when revenue pressure changes the cost calculus.
Since 3 February 2026 Base44 generates App Store (.ipa) and Google Play (.aab) files itself from the editor's Mobile app tab (Builder plan or higher): a web-view wrapper with push but no in-app purchases yet. We build what review still checks: web-side billing, privacy and account deletion, and a StoreKit shell when you need one. (Platform facts: docs.base44.com, read 23 Sep 2026.)
Document handoff, status tracking, role-scoped views. Auth surface is the security-critical layer; we audit it before ship.
Inbound webhook routing, retry logic, idempotency, dead-letter queues. The integration layer that base44 docs gloss over.
03 /PROCESS
Five stages, every time. The architecture stage is a common place for DIY builds to quietly fail; we treat it as the gate before any prompts run.
01/STEP
Free 15-minute call with the engineer who would lead the work. Written fixed-price proposal within one business day. You can send a product brief instead; either way we document requirements as a written spec, not assumptions, and we do not bill if you choose not to proceed.
02/STEP
We choose the right base44 data model, auth pattern, and integration surface before writing a single AI prompt. This is a common place for DIY builds to fail — committing to the wrong schema in week one and paying for it for weeks afterwards.
03/STEP
We build in a staged sequence: data model, auth, core workflow, integrations, polish. Each stage is checkpointed. We use structured prompt chains that prevent the AI agent from re-architecting components it has already shipped.
04/STEP
We test against the original spec on mobile and desktop. We use the base44 test environment to validate credit burn and webhook reliability before production. Findings are logged and fixed before handoff.
05/STEP
Code export, README with prompt documentation, dependency surface notes, and a 30-day defects warranty. We are added as a read-only collaborator for the warranty window so we can replicate any defect you report.

base44 is a real product and the AI agent does real work. It also has known failure modes that cost teams weeks. The honest comparison — and the case for putting a base44 expert on the build instead.

Base44Devs is one of five ways to get a Base44 app built. The gap between them is less the headline price than who pays when the build does not hold. Every external figure below carries its source and date.

05 /EXAMPLE
A hypothetical example, not a client record. It shows how a Standard-tier scope is shaped, from starting state to hand-off. Read it as the shape of the work.
WORKED EXAMPLE · STANDARD BUILD · 4–6 WEEKS
06 /AFTER LAUNCH
Every build carries a 30-day defects warranty. After it, you can keep a senior on the app with a monthly retainer, or book a $1,500fix sprint only when something breaks. Retainers need 30 days' notice to cancel.
Included · first 30 days
Any defect against the written spec is fixed at no charge. We stay on the app as a read-only collaborator for the window so we can reproduce what you report.
$2,000 / month
Priority on the urgent slots, a monthly regression check after Base44 updates, Slack triage and up to 10 senior hours a month.
$4,000–$8,000 / month
20–40 dedicated senior hours a month, up to 50% of unused hours roll over, the SLA written into the retainer letter, and second-senior review on auth, payments and data changes.
07 /FAQ
A done-for-you Base44 build from Base44Devs costs $4,500 for an MVP, $9,000 for a Standard build and $15,000 for a Premium build. Each price is fixed and quoted in writing before work starts, and every tier carries a 30-day defects warranty. For comparison, Base44's own blog puts a freelancer-built app at $5,000–$50,000+ and an agency-built app at $50,000–$500,000+ (published 12 Aug 2026).
A Base44 MVP takes 2–4 weeks: auth, one core workflow and one Stripe Checkout path, deployed to production with a code export and hand-off README. A Standard build takes 4–6 weeks and a Premium build 6–10 weeks. The fixed-price proposal commits to a delivery window, so there is no rolling hourly creep.
Yes. Every build ships with a code export, a hand-off README and full ownership transfer; IP assigns to you on payment of each milestone. There is no recurring license fee, no source-code lock and no escrow, and we mention the project in anonymised form only with your written permission. The exported code still calls Base44's backend through the @base44/sdk, so leaving the platform entirely is a migration, which the Premium tier's migration plan scopes.
A 30-day defects warranty is included on every build: within that window we fix any defect against the written spec at no charge. After 30 days we offer optional monthly Base44 engineering retainers (the Care plan at $2,000 a month or an Embedded senior at $4,000–$8,000 a month) or per-incident fix sprints from $1,500.
Because base44's AI agent has known regression loops, hallucinations on complex data models, and credit-burn patterns that turn into weeks of rework. The team has shipped or debugged 100+ base44 apps in production. It maintains 47 documented fix playbooks plus tested prompt structures and schema patterns that prevent these failure modes from the outset.
Yes. We design every build for handoff: clear naming conventions, documented prompts, a pinned dependency surface, and a hand-off README that names the files, prompts, and schema decisions a new engineer needs to know. You can keep iterating in base44 after delivery.
We tell you up front during scoping. If the platform cannot meet a critical requirement, we recommend a hybrid build (base44 + a small Next.js service for the constrained capability) or steer you to the migration practice. We do not bill for the conversation if it ends in a no.
Internal tools and admin panels, client portals with role-based access, SaaS dashboards with subscription billing, two-sided marketplaces with payments and escrow, and workflow automation tools with webhook triggers. Where base44 struggles: real-time collaboration, heavy file processing, single-region database performance at scale, and any workload requiring sub-100ms p99 latency.
Yes. The same team runs the /fix and /migrate practices, so a build engagement can transition into a monthly retainer or a migration plan if the app outgrows the platform. The Premium tier ships with a migration plan baked in for exactly this reason.
