Base44 solutions by industry.
Ten verticals, three fit categories, one honest assessment per page. We document where base44 actually ships well, where it ships with caveats, and where the platform is the wrong tool. Every entry is grounded in real client work — builds we have shipped, fixes we have run, migrations we have scoped.
Short answer
Last reviewed · 2026-05-08
base44 is a good fit for a narrow set of industries and a poor fit for several others. The platform ships well for internal tools, MVP and prototyping work, and most nonprofit applications— fast iteration, modest concurrency, and bounded user counts match the platform’s strengths. It works with caveats for SaaS, two-sided marketplaces, agency client portals, small DTC ecommerce, and pre-Series-A startups — viable for validation but each vertical has a structural limit that triggers a migration sometime between 500 and 2,000 active users. It is not recommended for production healthcare or fintech, because base44 has no Business Associate Agreement, no SOC 2 Type II at the customer-app layer, and no PCI attestation as of May 2026. Each solutions page documents the specific hardening hours, the platform limit that bites first, and the migration trigger for its vertical.
01 /WHEN BASE44 FITS
Which industries the platform actually serves well.
The honest version, written by engineers who have shipped or debugged more than 100 base44 apps. The point is not to sell the platform — it is to tell you, before you commit, whether your vertical is one base44 will help you ship or one it will quietly hold back.
base44 is at its best where three conditions hold simultaneously: a bounded user count, a modest read-write ratio, and a tolerance for sub-second-but-not-real-time interactions. Internal tools meet all three by definition. MVP and prototyping work meets them because the user count is, by construction, your design partners. Nonprofit workflows meet them because volunteer rosters and donor records do not generate burst write loads.
The platform ships with caveats when the user count is bounded but the surface area is regulated, billable, or multi-tenant. SaaS up to 500 paying customers is feasible, but only after you have hardened the row-level-security defaults, replaced the native webhooks with an external worker, and accepted that you will migrate to Postgres before your Series A. Two-sided marketplaces ship in two to four weeks, but you build escrow on Stripe Connect by hand and accept that real-time bidding requires Ably or Pusher because the platform has no WebSocket. Agency client portals work cleanly between four and twelve thousand dollars of build budget; thinner past that. The caveats are not deal-breakers — they are line items in the build plan.
base44 is not the right tool when the regulatory surface forces a posture the platform cannot match. Healthcare apps that custody protected health information are the clearest example: there is no BAA, no native audit log, and the July 2025 Wiz disclosure (SSO bypass, JWT leakage in URLs, stored XSS) showed a security posture mid-maturity at best. Fintech apps that touch card data, bank-grade integrations, or customer fund custody have the same problem from a different angle — no SOC 2 Type II at the customer-app layer, no PCI attestation, and SDK lock-in that becomes most expensive exactly when you need an audit trail. For these verticals, base44 is useful for marketing pages, education content, and pre-launch waitlists — and nothing past that line.
The decision is rarely “base44 vs custom.” It is “base44 now, custom later” for one set of verticals, and “custom from day one” for the other. The pages below tell you which set yours falls into and what changes inside that envelope.

WORKS WELL
3 verticals
- Internal ToolsBase44 for internal toolsFITS
The platform's clearest win — admin panels, ops dashboards, and approval consoles ship in days at modest concurrency. SSO bypass risk and missing audit log are the only two boxes you need to tick before production.
- MVP / PrototypingBase44 for MVP and prototypingFITS
Genuinely excellent for disproving an idea cheaply — 2-10 day builds that would take a traditional team six weeks. The discipline is to commit to a real stack before the prototype becomes the product.
- NonprofitBase44 for nonprofitsFITS
Donor portals, volunteer scheduling, grant trackers, and event registration map cleanly to base44's strengths. Be cautious only with PII-at-scale and PCI Level 1 payment flows.
WORKS WITH CAVEATS
5 verticals
- SaaSBase44 for SaaSCAVEATS
Viable up to roughly the first 500 paying customers if you accept three trade-offs: harden RLS, run dunning on an external worker, and plan migration before Series A. Use to validate, not to scale.
- MarketplaceBase44 for marketplacesCAVEATS
Two-sided marketplace MVPs ship in 2-4 weeks but the platform has structural gaps — no WebSocket for real-time bids, no native escrow, single-role identity layer. Good for validation, hard at scale.
- StartupBase44 for startupsCAVEATS
Powerful accelerator from day zero through Series A but caps somewhere in the 500-2,000 user range. Plan the migration before due diligence — investors will ask about your stack and the conversation is smoother once you have already moved.
- EcommerceBase44 for ecommerceCAVEATS
DTC stores under 1,000 SKUs and 500 orders a month can ship a working storefront. Past that, Stripe-integration drift, inventory consistency, and iOS App Store rejection make Shopify or a custom Next.js stack the better answer.
- AgencyBase44 for agenciesCAVEATS
Margin math works on $4,000-$12,000 client builds — fast, hosted, defensible. Thin past that, and unsuited for true white-label resale or per-client compliance posture. Use it where speed beats brand polish.
NOT RECOMMENDED
2 verticals
- HealthcareBase44 for healthcareAVOID
Not recommended for production apps that touch PHI — there is no BAA, no native audit log, and the July 2025 Wiz disclosure showed a security posture incompatible with PHI custody. Safe only for non-PHI surfaces.
- FintechBase44 for fintechAVOID
Not recommended for production fintech — no SOC 2 Type II at the customer-app layer, no PCI attestation, no support for Plaid or Treasury Prime. Useful only for marketing surfaces, education, and pre-launch prototypes with no card data.
03 /DECISION FRAMEWORK
Three axes that matter more than the vertical label.
Vertical is a useful first filter, but the real decision is made on three orthogonal axes. Score your app on each before you commit — the answer is usually clear once the numbers are on paper.
AXIS 01 · PRODUCTION-READINESS
Will the app survive contact with real users on day one?
Auth, RLS, payments, webhooks, and audit logging are all places where base44 defaults are unsafe for production. If your app touches any of them, the build needs hardening — not patches later, hardening before launch. The $497 production audit gives you a written verdict in 5 business days. The /fix index documents the 29 most-cited failure categories with remediation playbooks.
AXIS 02 · VENDOR-LOCK-IN COST
What does it cost to leave when the platform stops fitting?
Lock-in cost is a function of how deeply the base44 SDK is embedded in your application logic. Teams that wrap the SDK in their own data-access layer from day one finish a migration in half the time of teams that let SDK calls leak into every component. The /migrate page covers the full exit cost by tier, plus the migration ROI calculator for the break-even date specific to your spend.
AXIS 03 · SCALE CEILING
When does the platform stop being the cheapest answer?
Soft ceiling for typical CRUD-heavy apps is 500-2,000 monthly active users; lower for write-heavy or real-time workloads. Symptoms before the ceiling: 429 rate-limit errors on burst traffic, editor hangs past 30 components, queries slowing past two seconds on larger collections. None are advertised limits; they emerge from the documented architecture (no WebSocket, single Deno runtime per backend function, no read-replica option). Plan the migration before the ceiling, not after.

04 /FAQ
Frequently asked questions
Q.01What industries is base44 actually well-suited for?
Internal tools, MVPs and prototypes, and most small-to-mid nonprofit workflows are the cleanest fits. SaaS, marketplaces, agency client portals, and small DTC ecommerce work with caveats — usually around RLS hardening, webhook reliability, or a planned migration. Healthcare and fintech are not recommended for production unless the surface is explicitly non-regulated. Each /solutions/[vertical] page documents the specific fit, the hardening checklist, and the migration trigger for that industry.
Q.02Is base44 production-ready for my specific use case?
Use this rule: if your app handles auth, payments, multi-tenant data, or anything regulated, base44 needs hardening before production. If your app is internal-facing, low-concurrency, and the user base is bounded, the defaults are usually fine. The honest answer for the borderline cases is in the per-vertical page — every solution page lists the specific hardening hours, the platform limit that will bite first, and the migration trigger so you can decide before you commit.
Q.03When should I migrate off base44 instead of staying on the platform?
Five concrete triggers: monthly credit cost exceeds the amortised cost of a custom stack, a compliance audit needs SSR or data residency base44 cannot provide, the app needs an SLA above what base44 publishes, the AI agent's context-window limits start blocking feature development, or vendor risk after the Wix acquisition becomes unacceptable. Our /migrate page covers the full decision framework and pricing.
Q.04How do you decide which vertical pages to publish?
Each cluster page is grounded in real client work — engagements where we either shipped a build, ran a fix sprint, or scoped a migration in that vertical. We do not publish a solutions page for a vertical we have not shipped at least three production apps in. The 10 pages here cover the verticals where we have enough data to give an honest fit assessment, including the two (healthcare and fintech) where the answer is to use the platform sparingly.
Q.05Can the same engineers build, fix, and migrate across these verticals?
Yes — the same senior engineers run all three practices. A build engagement that ships a SaaS MVP can transition into a fix retainer when the AI agent breaks something post-launch, then into a migration plan once the app outgrows base44's single-region database. We document every engagement against a regression test plan so the next phase has a clean handoff.
Q.06What does a base44 industry-specific build cost?
Build pricing is fixed by tier, not by vertical: $4,500 MVP (2-4 weeks, auth and one core workflow), $9,000 Standard (4-6 weeks, multi-role auth, Stripe, webhooks, observability), $15,000 Premium (6-10 weeks, custom integrations, UX pass, migration plan baked in). What changes per vertical is the hardening work — multi-tenant SaaS adds 15-25 hours of RLS audit, marketplaces add escrow plumbing, healthcare needs a BAA-eligible target stack from day one.
Q.07Should I read the per-vertical page before booking a call?
If your industry is in the index above, yes — it will save 20 minutes on the scoping call. Each page documents the platform limit that bites first in that vertical, the specific hardening hours, the realistic monthly cost, and the migration trigger. If your industry is not listed, the call is the right place to start; we are honest about where base44 fits and where it does not, and we do not bill for the conversation if it ends in a no.
