Bubble vs Saltcorn

Bubble is a platform for building web and mobile apps, with support for Android, iOS, and the web. Projects can use a built-in database, authentication, API integrations, and shared workflows and backend across web and mobile apps. Users can build before paying to launch. The Free plan includes one app editor, 50K workload units per month, and six hours of server logs. Native mobile apps can be published to the iOS and Android app stores, and production-ready apps include security scanning. Bubble can connect with services such as Stripe and Google Maps. A 14-day trial is listed; unless canceled, it converts to a paid Starter subscription. Starting that trial involves a temporary $1 card pre-authorization, which expires within 5-10 business days. Starter Web + Mobile costs $59 a month, billed annually; Growth costs $209 a month, billed annually, and Team costs $549 a month, billed annually. The maker is Bubble Group, Inc., headquartered in New York, NY, United States, and founded in 2012.

Saltcorn is an open-source database app builder for making custom applications, workflows, and interfaces. Its visual tools let users create relational tables and assemble forms, dashboards, portals, and workflows with drag-and-drop components. It runs on PostgreSQL or SQLite and includes a JSON REST API for other systems to read and write data. Plugins can add data types, views, and themes; listed extensions include Apple Pay, CalDAV, CAPTCHA, charts, and AI agents. Applications can be packaged for iOS and Android, with offline use supported by local SQLite storage and later synchronization. Deployment options include Docker, Kubernetes, npm, marketplace templates, desktop use, and air-gapped self-hosting. Self-hosted instances make no telemetry calls and can run offline behind a firewall. The MIT-licensed platform has no licence fee or per-seat cost. The open-source platform is free; DigitalOcean marketplace deployment is $6 a month, and managed hosting via Elestio is $16 a month. Shared free evaluation hosting is not intended for production or real data.
