Move your Base44 app without losing sight of how it works.
We migrate Base44 applications to infrastructure you control. The work starts with your entities, users, permissions, functions and integrations—not just the exported interface. You get an agreed target architecture, a migration scope and a plan to verify the app before changing production.
Exporting the frontend is one part of the move.
An exported interface can still call Base44 for records, authentication and privileged operations. Changing where that interface is hosted does not replace those services. A full migration needs an explicit inventory of what stays, what moves and what must be reimplemented. If Base44 still meets your needs, staying on it or making a smaller change can be the better decision.
What you get.
An inventory of platform dependencies
We map entities, relationships, file references, sign-in methods, backend functions, scheduled work and external providers. Function count helps estimate effort, but a payment reconciliation function can take more work than several simple record lookups. We inspect the behaviour behind the count.
A target stack chosen for your requirements
Managed Supabase with appropriate frontend hosting can suit apps that need Postgres, authentication, storage and functions together. A custom API may fit more involved business rules. Self-hosting adds operational responsibility. We compare these options against region, budget, maintenance capacity and expected workload.
Data and identity mapping
We define how old identifiers, relationships, dates, nullable values and file references map into the target system. User records and authentication credentials are different things: we check supported transfer options and plan reauthentication or resets where needed. A copied email address is not a migrated session.
Backend and integration replacement
Entity calls, privileged functions, OAuth callbacks, webhooks, email and AI-provider connections are reviewed individually. A compatibility layer can reduce frontend changes; a direct rewrite can simplify a small, centralized client. We choose based on the actual callers, not a universal migration template.
Permission and workflow verification
Old access rules become explicit target rules and tests. We check representative users, staff roles, record ownership, billing transitions and imported files. Matching record counts is useful but insufficient: relationships, values and permitted operations also need verification.
Cutover, recovery and handover
We agree backups, a restore check, final data synchronization, DNS and webhook changes, a rollback decision point and the handling of writes made during cutover. The handover identifies the accounts you own and the responsibilities that move from the platform to your team.
How it works.
- 01
Assess what must move
We review the current app and your reason for migrating. A frontend-only deployment that retains Base44 as a backend is distinguished from a full platform exit.
- 02
Rehearse on an isolated target
We build the target implementation and rehearse the import with agreed test data. Known gaps and provider constraints are documented before a production cutover is scheduled.
- 03
Verify the business journeys
We compare expected records and behaviour, including customer isolation and critical integrations. You approve the agreed acceptance checks; unresolved differences are not hidden in a launch checklist.
- 04
Move production deliberately
We execute the agreed synchronization and traffic switch, observe the key workflows and keep recovery options for the agreed window. Downtime and support terms are scoped, not universally promised.
Common questions.
- Does a Base44 code export include a replacement backend?
- Do not assume so. We inspect which services the exported app still calls. Hosting the frontend elsewhere can leave Base44 handling data and auth; a complete exit requires replacing or migrating the relevant backend services.
- Do all users keep their passwords and sessions?
- That depends on the supported export and target authentication paths. We verify what can transfer, map user identities and explain any re-login or reset process before cutover. We do not promise portable sessions without checking.
- Is Supabase always the right destination?
- No. It is an option when its database, auth, storage and function services match the app. Requirements for a custom API, background processing or operations may lead to a different architecture.
- Will the app be cheaper or faster afterwards?
- Not automatically. We compare hosting, database, file storage, email, AI usage and maintenance costs. Performance depends on queries, application design and capacity; migration alone is not a benchmark.
- What affects the migration quote?
- Entities and relationships, backend function complexity, integrations, authentication, files, data quality and cutover constraints all matter. The migration scope worksheet helps collect these without sharing secrets.
