Short answer
Last reviewed · 2026-05-02
Migrating off base44 with Base44Devs involves three deliverables: a data export and schema map, a code rewrite on the target stack, and a DNS-cutover plan with a tested rollback path. The default target is Next.js + Supabase on Vercel. Fixed-price migrations start at $6,000for apps with up to 5 tables and 10 routes (Small), $12,000 for up to 20 tables with multi-role auth and Stripe (Medium), and $25,000+ for multi-tenant or SOC 2 / HIPAA-compatible builds (Enterprise). Typical production downtime at cutover is under five minutes; the base44 workspace stays live as rollback for a 14-day stability window after switch.
01 /WHEN TO MIGRATE
Migration is not the right call for every base44 app. If none of the triggers below applies, staying on the platform is usually the cheaper move. We will tell you that on the scoping call.
TRIGGER 01
Run the numbers in the migration ROI calculator. The break-even is roughly when base44 credits exceed the cost of an equivalent Next.js + Supabase deployment plus a part-time engineer. Read more →
TRIGGER 02
base44 renders client-side by default and is single-region. SOC 2, HIPAA, GDPR data-residency, and similar audits often require SSR + regional control that the platform does not expose.
TRIGGER 03
base44 has no published customer SLA as of May 2026. Enterprise customers requiring 99.9%+ uptime guarantees have to either accept platform risk or migrate.
TRIGGER 04
The AI agent's context resets across sessions and rewrites components on long runs. Past a certain product complexity the agent costs more time than it saves.
TRIGGER 05
The Wix acquisition (announced 2025) introduced platform-strategy uncertainty. If your business cannot tolerate roadmap or pricing changes outside your control, migration de-risks the dependency. Read more →

04 /TARGET STACK
The default target is not arbitrary. It solves the two biggest base44 limitations directly while introducing no new vendor lock-in.
We default to Next.js + Supabase because it solves the two biggest base44 limitations directly: Next.jsprovides server-side rendering that base44’s CSR-only architecture cannot, which fixes SEO, Time-to-First-Byte, and Largest Contentful Paint in one deployment. Supabaseprovides Postgres-backed Row-Level Security that mirrors base44’s permission model with full portability — including the ability to self-host the database later. The combination is deployable to Vercel in one command, open-source at every layer, and introduces no new vendor-specific lock-in beyond standard Postgres + Node.
Alternative targets we ship to: self-hosted Postgres + Node (when SOC 2 demands self-hosting), Firebase (when teams want a managed BaaS without Postgres), and other no-code platforms like Bubble, Lovable, Bolt, or Replit if a no-code-to-no-code move makes sense for your team.
05 /CUTOVER
Four phases. The base44 app stays live until the new stack passes acceptance, so production users feel nothing during the build.
01/PHASE
All base44 tables are exported to portable SQL. Referential integrity is verified before any rebuild work starts. Foreign-key constraints, enums, and default values are preserved.
02/PHASE
The replacement stack is built alongside the live base44 app with no disruption to production users. Auth, RLS, payment integrations, and routes are reimplemented against the original spec.
03/PHASE
A test pack covering all critical workflows is run against the new stack before cutover. Pass criteria: 100% functional parity on the canonical user journey, no data divergence on the seeded record set, p95 latency at or below the base44 baseline.
04/PHASE
DNS is switched with the base44 app kept live as rollback. Typical production downtime is under 5 minutes. The base44 workspace is not deleted until a 14-day stability window passes.

07 /FAQ
When monthly credit cost exceeds the amortised cost of a custom stack, when you need an SLA base44 does not offer, when SEO or compliance constraints make CSR-only rendering a blocker, when the AI agent's context-window limits are slowing feature development, or when vendor-risk concerns following the Wix acquisition put the business at risk. The /audit engagement includes a migration cost projection if you want a quantitative answer before committing.
We design every cutover with a tested rollback path. The default plan keeps the base44 app live until DNS is switched and the new stack passes acceptance — typical production downtime is under 5 minutes. The base44 workspace is not deleted until the new stack passes a 14-day stability window, so rollback remains possible even after cutover.
Both. Data migration is a first-class deliverable: we export, transform, and load with referential integrity preserved. Auth user records, Stripe customer + subscription records, all application records, and webhook integrations are migrated. We never ask you to rebuild data manually.
Default target is Next.js + Supabase on Vercel. We also migrate to self-hosted (Postgres + Node), to Firebase, or to other no-code platforms (Bubble, Lovable, Bolt, Replit) — see the comparison pages for trade-offs. We pick the target stack that matches your team's skills, compliance requirements, and budget envelope.
Visually yes by default — we match the existing UX 1:1 unless you ask for a redesign. We do clean up obvious base44 quirks (CSR-only rendering, default styles, AI-generated layout drift) so the new app loads faster and ranks better in search. SSR support alone typically improves Largest Contentful Paint by 1-2 seconds.
Base44's data export covers all tables, records, auth users, and your application code. What does not auto-export: AI-agent prompt history (not portable), the platform's internal credit ledger (not customer-accessible), and base44's native analytics (we replace with standard analytics — Plausible, PostHog, or GA4 — in the new stack).
Fixed-price tiers based on table count and complexity: Small ($6,000, up to 5 tables and 10 routes, 2-3 weeks), Medium ($12,000, up to 20 tables, multi-role auth, Stripe, 4-5 weeks), Enterprise ($25,000+, multi-tenant architecture, SOC 2 / HIPAA-compatible, custom integrations). We quote custom for anything beyond Enterprise after a scoping call.
It stays active until cutover. We bill for the new stack to come online in parallel, then switch DNS once acceptance passes. After the 14-day stability window post-cutover, you cancel your base44 subscription and the workspace is archived. We do not require base44 to be deleted as a condition of any rollback.
