The trade-offs

Strengths and Limitations

Emergent

Strengths

Deploys to a live URL with a custom domain and automatic SSL, no pipeline to set up
Web and Expo mobile apps come from the same platform
Code pushes to GitHub, and an existing repository can be imported

Limitations

The stack is fixed, with no Flutter, Kotlin or Swift
Every deployed app draws 50 credits a month on top of the plan
Large gap between the Standard and Pro plans, at $20 and $200 per month

Retool

Strengths

Connects to any database, API or LLM provider instead of starting from its own data
Self-hosting is available on every tier, the free one included
Extensible with JavaScript everywhere and custom React and TypeScript components

Limitations

Priced per builder and per internal user, so cost tracks headcount rather than apps
Apps are not an exportable codebase, so leaving the platform means rebuilding
Git source control, SSO and SCIM are Enterprise-only
