Check the exit before you build.
- Can you download the full application code yourself, and run it without a rebuild?
- Is the output standard: a React front end and a WebAssembly back end, TypeScript by default?
- Is the model compiled to code, so there is no AI-written code to review line by line?
- Does the exported code pass through your own CI/CD and GitHub workflow?
Betty Blocks says it offers self-serve code export (release notes, June 24, 2026) and standard React and WebAssembly output (bettyblocks.com, October 2026). Ask any vendor to demonstrate the same.
Five questions to ask the vendor.
- Who can publish an app, and who approves the change?
- Where do prompts, records and logs actually go?
- What happens to the bill when usage doubles?
- What can our team run after the contract ends?
- Can you demonstrate recovery and export on our use case?
Three red flags.
- A flat price with undefined usage limits.
- An export promise that has never been tested outside the platform.
- Governance controls that depend on an undocumented manual process.
