The trade-offs
Strengths and Limitations
Bubble
Strengths
- Builds web and native mobile apps in a single editor
- Generates a complete app from one prompt with the AI app builder, then lets you refine it
- Large ecosystem of community-made plugins and connectors
Limitations
- Priced in monthly workload units, so a busy app's running cost rises with usage instead of staying fixed
- The free plan cannot run a live app on a custom domain
Caspio
Strengths
- HIPAA, SOC 2 Type II and GDPR certified annually by independent audit, not self-attested
- Unlimited app users on every plan, so cost does not grow with the audience
- Phone, live chat and ticketing, staffed by in-house support engineers rather than outsourced
Limitations
- Entry pricing starts at $270 a month, well above most tools in this category
- Apps live on the platform rather than as an exportable codebase
- Builder seats are capped on the Team plan at five app authors
