MVP to production-grade. We design, build, and document base44 apps that survive contact with real users — and ship clean code you can take with you. Fixed-price, no hourly creep, 30-day defects warranty included.

A done-for-you base44 build from Base44Devs is a fixed-price engagement that ships a production-grade base44 app you fully own. Three tiers cover the range: an MVP at $4,500 (2-4 weeks, auth and one core workflow), a Standard build at $9,000 (4-6 weeks, multi-role auth, Stripe, webhooks, observability), and a Premium build at $15,000 (6-10 weeks, custom integrations, UX pass, migration plan baked in). Every build includes full code export, a hand-off README, and a 30-day defects warranty. Senior engineers only — no junior delegation, no offshore hand-off, no AI hand-waving. Base44Devs has shipped or debugged more than 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 is the mix we ship most often. Each links to a deeper solutions page.
Multi-role auth, Stripe with proration and dunning, role-scoped data, webhook reliability. The most common engagement shape.
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.
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 where most DIY builds quietly fail; we treat it as the gate before any prompts run.
01/STEP
You send a product brief or we run a 30-minute scoping call. We document requirements as a spec, not assumptions. The call is free 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 where most DIY builds fail — committing to the wrong schema in week one and paying for it in weeks four through eight.
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.

04 /VS. DIY
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.

06 /FAQ
Because base44's AI agent has known regression loops, hallucinations on complex data models, and credit-burn patterns that cost teams two to four weeks of rework. Base44Devs engineers have shipped more than 100 apps on the platform and maintain a documented library of workarounds, optimised prompt structures, and tested schema patterns that prevent these failure modes from the outset. Most teams that hire us have already spent 4-8 weeks fighting the AI agent before reaching out.
You do. Every build ships with a code export, a README, and full ownership transfer. We retain the right to anonymised case-study mentions only with your written permission. There is no recurring license fee, no source-code lock, and no escrow.
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. Most teams continue 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.
Yes — a 30-day defects warranty is included on every build. Within that window we fix any defect against the original spec at no charge. After 30 days we offer optional retainers ($2,000-$5,000 / month) or per-incident fix sprints from $1,500.
MVP builds (auth + 1 core workflow) deliver in 2-4 weeks. Standard builds (multi-role auth, Stripe, webhooks, observability) deliver in 4-6 weeks. Premium builds (custom integrations, UX pass, migration plan) deliver in 6-10 weeks. We commit to a delivery window in the fixed-price proposal — no rolling hourly creep.
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 fix 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.
