Builder.ai Shut Down: How to Recover Your App and Source Code
Quick triage: what is your situation?
- You had a Builder.ai app that is now down and you need source code to continue development What code exists
- You want to know if Builder.ai stored your code and whether it can be retrieved What code exists
- You need to rebuild or migrate your app to a new platform as fast as possible Recovery options
- You are evaluating whether to rebuild from scratch vs. salvage what exists Rebuild vs. migrate
What Happened to Builder.ai
Builder.ai, operating under parent company SAIT (Software AI Technology), entered insolvency proceedings on May 20, 2025. Creditor Viola Credit seized $37 million from company accounts, leaving Builder.ai with approximately $5 million in cash -- not enough to cover its debts. The platform shut down operations, and customer apps went offline.
The collapse exposed a significant gap between what Builder.ai marketed and what it delivered. Despite claiming AI-driven development, investigations found that the majority of the work was done by approximately 700 engineers in India and Ukraine who manually wrote code in response to customer requests. Revenue was also misreported -- claimed at $220 million for 2024 when the actual figure was closer to $55 million.
For customers, this meant two immediate problems: apps went dark without notice, and source code access became uncertain. The insolvency process put all assets, including code repositories and infrastructure, under the control of administrators.
What Code Typically Exists (and What Doesn't)
Builder.ai customers fall into three categories based on what code is recoverable:
Category 1: Code was delivered and is in your possession
Some Builder.ai contracts included periodic code deliveries or GitHub access. If you received a repository access or a code export before May 2025, you have something to work with. The code quality varies significantly -- it was written by human developers, not AI, which means it can range from well-structured to inconsistent.
- [ ] Locate your last code export or GitHub repository access
- [ ] Verify you can still access the repository (some were on Builder.ai-managed accounts)
- [ ] Document which features are complete vs. incomplete
- [ ] Identify your tech stack (Builder.ai typically used React/Node.js)
- [ ] List all third-party integrations and their API keys
Category 2: App was deployed but no code was delivered
If your app was running but you never received source code access, the code existed on Builder.ai's servers. Whether this is accessible depends on the insolvency administrators and the specific contract terms. Realistically, retrieving code from a company in administration is slow, legally uncertain, and not guaranteed.
The practical approach here is not to wait for administrators to release code, but to reconstruct your app. If you have a running version (even now offline), screenshots, feature documentation, or any export from the platform, that becomes the specification for reconstruction.
Category 3: App was in development and never launched
If your Builder.ai project was still in development when the platform closed, the starting point is whatever documentation, designs, or partial builds you received. In most cases, reconstruction from a clear specification is faster than recovering incomplete, platform-specific code.
When to call an expert: If you have existing code and need it audited, completed, and deployed -- or if you need a reconstruction scoped and started -- AppStuck handles both scenarios. We've done Builder.ai migrations before and can give you an honest assessment of what is salvageable and what is faster to rebuild.
Recovery Options
There are three viable paths depending on your situation:
Option 1: Complete and deploy existing code
If you have a code export that is mostly complete, the fastest path is to finish the incomplete parts and deploy. This requires a developer who can read the existing codebase, identify what is missing, and complete it to a deployable standard.
Builder.ai projects typically used React for frontend and Node.js for backend. The code quality varies by which team built your project, but it is generally completable. The main gaps are usually: production deployment configuration, environment variable setup, and any features that were in progress at shutdown.
- [ ] Audit the codebase for completeness (which features are implemented vs. stubbed)
- [ ] Set up local development environment to verify what runs
- [ ] Identify all external service dependencies (databases, auth providers, payment gateways)
- [ ] Configure production environment (Vercel, Railway, or equivalent)
- [ ] Transfer any domain, DNS, and SSL configuration away from Builder.ai infrastructure
- [ ] Establish version control in a repository you own
Option 2: Reconstruct from documentation and design
If the code is not recoverable, reconstruction from documentation is often faster than waiting for administrators. You need: a clear feature list, any designs or screenshots of the working app, and access to any data that was stored in the platform.
A well-documented reconstruction project can typically be scoped in one week and completed in two to six weeks depending on complexity. Modern AI tools (Lovable, Bolt, Cursor) can accelerate the frontend build significantly -- but require experienced developers to complete the backend, auth, and deployment layers.
Option 3: Platform migration
If your app is relatively simple (internal tool, booking system, basic CRUD application), rebuilding on a modern no-code platform with better ownership terms is sometimes faster than a full code reconstruction. This is only a good option if you are not planning significant custom feature development -- platform lock-in was part of what made Builder.ai's shutdown so damaging.

| Factor | Lean toward rebuilding | Lean toward migration |
|---|---|---|
| App complexity | Custom logic, complex workflows, integrations | Simple CRUD, internal tool, basic booking |
| Existing code quality | Partial but structured codebase exists | No code, or code is unusable |
| Future development plans | Significant new features planned | App is mostly complete, minimal changes needed |
| Budget | Higher short-term cost, lower long-term | Lower short-term cost, potential lock-in risk |
| Timeline | 2-6 weeks for a full rebuild | 1-2 weeks to migrate to a new no-code platform |
| Data | Complex data models, regulatory requirements | Simple data, easy to export and reimport |

Frequently Asked Questions
Can Builder.ai administrators release my source code?
Potentially, but the process is slow and uncertain. Insolvency administration involves court-supervised asset management. If you believe you are entitled to specific code assets, consult a solicitor with experience in insolvency proceedings. In parallel, pursue the reconstruction path -- waiting for administrators is rarely the fastest option for getting your product back online.
Builder.ai said I owned the code. Does that help?
Contract terms that gave you code ownership are legally meaningful but practically limited when the company holding the code is in administration. The ownership claim matters for any legal proceedings but does not give you immediate access to the code on Builder.ai's servers.
My app has active users. What do I do immediately?
First priority: communicate with your users about the situation and expected downtime. Second: if any data was stored by Builder.ai, contact the administrators to understand data retrieval options before it is deleted. Third: scope a reconstruction so you can give users a realistic timeline.
Can you work with partial Builder.ai code?
Yes. Even incomplete or poorly documented code is a better starting point than nothing. We can audit what exists, identify what is missing, and complete it. Most partial Builder.ai codebases are completable within 2-4 weeks.
What tech stack does Builder.ai code use?
Builder.ai projects typically used React or Angular for frontend, Node.js for backend, and various databases depending on the project. The stack was decided by the engineer who built your project, not a single standard. Our first step in any migration is a tech stack audit to understand exactly what you are working with.
