Base44 to Astro or Next.js
Give the public site its own codebase
When the generated app is doing a marketing site's job, I move the public pages into Next.js or Astro so they stay fast, indexable and owned. First question: what Base44 will hand back. I establish that in writing before quoting. The application that is doing useful work stays put.

What moves
What actually migrates.
| What you have | What happens | Why |
|---|---|---|
| Public pages | Rebuild Made again in the new codebase. The old version is a reference, not an import. | The existing front end is the reference for the Astro build. Public routes are rebuilt as deliberate pages and components rather than regenerated as another application. |
| Front-end components | Reconfigure The same thing, set up again. Nothing is recreated, but it has to be pointed at the new site by hand. | The exported code is real source material. Interactive components may survive largely intact; content-heavy ones are usually simpler to rebuild without the application runtime they no longer need. |
| Publishing content | Move Comes across as it is. The content survives the move and the work is transporting it, not remaking it. | Copy, resources, testimonials and FAQs move into whichever content model the marketing site uses. |
| Application data | Stays put Does not move, on purpose. The old platform keeps this because it is the thing it is good at, and the new front end reads from it. | User records and genuinely dynamic product data do not need to move because the front end did. Astro reads Base44 through its SDK where the public site needs that data. |
| Authentication | Stays put Does not move, on purpose. The old platform keeps this because it is the thing it is good at, and the new front end reads from it. | The marketing site should not acquire authentication because the application has it. Product routes keep using Base44 auth while the public routes stay public. |
| URLs | Reconfigure The same thing, set up again. Nothing is recreated, but it has to be pointed at the new site by hand. | Every known public address is inventoried, preserved where practical and deliberately redirected where the routing changes on purpose. |
Boundary
Where the line falls.
After the migration
Astro
The public site
- Marketing and campaign pages
- Documentation and resources
- The content model, in collections or a CMS
- Every address search already knows
The seam
The Base44 SDK
- Entities read where a public page needs them
- The signed-in handoff, at the product's door
- One source of truth, never a second copy
Base44
The application
- Authentication and accounts
- The database and its records
- Backend functions and integrations
- Everything behind the login
Hard parts
Where this migration gets complicated.
- 01
Deciding where the application ends
The front end, the authentication, the database and the backend functions all live in one Base44 project, and that does not mean they should all move. The planning work is naming which routes are really documents and which are genuinely part of the product.
- 02
Keeping one source of truth
If Base44 stays the backend, product data stays there and Astro reads it rather than holding a copy. Publishing content can move into a CMS or content collections, but application records must not quietly fork into two systems that disagree.
Process
How the migration works.
-
Audit
Every public route, authenticated route, entity, backend function and integration, sorted into website and application.
-
Rebuild
The public front end becomes Astro components, with Base44 connected through its SDK where the pages need it.
-
Migrate
Publishing content into the new model, addresses preserved or redirected, and the Base44 services in use stay live.
-
Hand over
The repository, the migration map and documentation written for somebody who was not here.
Included
What is included.
-
Design rebuild
Rebuilt as components, not approximated.
-
Responsive development
Desktop, tablet and mobile, built and checked.
-
CMS architecture
Collections and fields mapped before build.
-
Content migration
Migrated and checked against the source.
-
Asset migration
Collected, compressed and rehosted.
-
Forms and integrations
Tested through to the final record.
-
URL coverage
Every known public address preserved or deliberately redirected.
-
Metadata and canonicals
Preserved wherever possible.
-
Search footprint preservation
URLs inventoried before and checked after.
-
Pre-launch QA
Forms, templates and old URLs verified.
-
Post-launch support
30 days of indexing and traffic checks included.
After those 30 days, Continuous development is the optional way to keep shipping: $1,000 a month for the Everbase Agent, or $3,500 a month for the Partner Program (human QA on every deploy and one active request at a time), pause or cancel any month.
Search visibility can move during a migration. The goal is to preserve what search engines already understand, and to catch what changed quickly after launch.
And it is yours at the end. The repository sits in your organization rather than mine, the handoff documentation is written for somebody who was not here, and nothing about the project requires me: another developer or your own team can operate it.
Editing
Separate publishing content from application data.
-
01
Content Collections, in the repository
For a team that publishes rarely and is happy in a pull request. The content is files beside the code, typed and checked at build time, with no service to pay for and nothing to keep running. It stops suiting you the day somebody outside engineering needs to publish without help.
-
02
Sanity
For a team that publishes regularly, or where the person writing is not the person deploying. Editors get a real interface, the model is explicit, and the site reads it at build time. It is another system to configure and pay for, and the modeling is the part that decides whether editors can work on their own.
-
03
No CMS at all
For a site whose pages change a few times a year. Everything lives in components, changes go through the same review as any other change, and there is no editorial layer to maintain. Honest for a small site, and the wrong answer the moment a blog is added.
Content Collections against a headless CMS, and how the choice is made.
Proof
A migration is not finished when the new site looks right.
-
01 Codebase
A codebase your team owns
Components, routes and styles rebuilt deliberately, not cleaned up from exported markup.
Verified by Repository and component structure
-
02 Site
Everything accounted for
Collections, content, metadata and existing addresses checked against the source.
Verified by Source inventory and migration checks
-
03 Systems
Handoffs that actually arrive
Forms, analytics and CRM checked at their destination rather than at the button.
Verified by Submissions, events and records
The migration is complete when these pass, not when the homepage looks right.
The figures above show the report's shape. Yours are counted from your own site.
Maintenance
Keep the agent workflow. Make the architecture explicit.
The important part is not that an agent can write code. It is that the project is structured well enough for its changes to be understood, reviewed and reversed.
-
Marketing
Editor or AI assistant CMS Preview Publish
On the headless CMS answer above. Choose content collections instead and this lane runs through the repository and the review with the developers, which is exactly why that decision comes before the rebuild rather than after it.
-
Developers
Branch Components and routes Review Deploy
The same workflow as any other repository, which is what makes a second developer able to pick it up.
-
Coding agents
Project instructions Branch Review Deploy
Coding agents use the same repository and review process as developers. Instructions explain the patterns; tests and a human review check the changes before release.
Integrations
Changing the frontend doesn't mean changing your stack.
-
HubSpot
Forms that land in the CRM as records, confirmed by the server rather than by the browser.
CRM
-
Sanity
A content model the marketing team edits and the build renders, with a defined preview and publishing path.
CMS
-
Google Analytics
Traffic and conversions measured against the routes the site actually has.
Analytics
-
Stripe
Checkout handled by Stripe, with the webhook as the record that decides what happened.
Payments
-
Mailchimp
Signups that reach the audience exactly once, whatever the visitor clicks.
Email
-
Zapier
Site events handed to the automations the team has already built.
