Why do people leave Bubble?

Performance limitations at scale, vendor lock-in (Bubble-specific logic is hard to migrate), cost increases, and the steep learning curve are the most common reasons.

Can Greta.sh replace Bubble for complex apps?

For most SaaS use cases, yes. Greta.sh generates clean, standard code that handles complex business logic without the limitations of Bubble's runtime.

Is there a way to migrate from Bubble to Greta.sh?

You can't import Bubble logic directly, but you can rebuild your product in Greta.sh — often faster than expected, because Greta.sh's AI generation dramatically speeds up development.

How we evaluated this comparison

This comparison draws on each vendor’s public pricing pages, product documentation and marketing material, plus hands-on use of Greta.sh — not a hands-on rebuild of the same application in every tool. Prices and limits are the published list figures at the date below, not promotional rates; vendors change plans often, so check their pricing page before deciding. Where a tool is the better choice for a given job, the page says so.
