NocoBase
open sourceNocoBase CommunitySelf-host24kaug 2026A full database-backed web-app builder with pages, roles, actions, workflows, and plugins; more business app than consumer startup.
The catch vs BubbleNocoBase is fundamentally a database-backed administrative app builder, so it gives up Bubble's consumer-app design freedom and front-end plugin ecosystem.
Install, platforms & data +
- platforms
- webself-hosteddocker to self-host
- install
- NocoBase CLI or Docker deployment with MySQL, MariaDB, or PostgreSQL
- setup
- Requires a database, secrets, and deployment administration; the community license also preserves NocoBase branding and restricts some uses

Corteza
open sourceApache-2.0Self-host2.1kmar 2026A self-hosted business-app suite with records, pages, workflows, charts, and enterprise-grade amounts of configuration.
The catch vs BubbleCorteza is a record-and-workflow suite, not a pixel-flexible public web-app designer, so a consumer-facing Bubble product will look and behave much more constrained.
Install, platforms & data +
- platforms
- webself-hostedself-host, real ops
- install
- Docker Compose with a configured MySQL or PostgreSQL database
- setup
- Docker, a database, secrets, persistent-volume permissions, and a reverse proxy/TLS are the first operational hurdle

Joget Community Edition
open sourceGPL-3.0Self-host607may 2026Forms, lists, workflows, and role-aware apps from a product old enough to have survived several no-code fashions.
The catch vs BubbleJoget excels at forms and workflows but cannot approach Bubble's freedom for bespoke public-facing layouts, interactions, and responsive design.
Install, platforms & data +
- platforms
- desktopwebself-hostedone-click install
- install
- Download the Community Edition bundle or deploy its Docker image/on-premises package
- setup
- The first real hurdle is administering a Java web stack and database rather than clicking through a managed signup

REI3
open sourceMITSelf-host571aug 2026A sober business-app builder with forms, reports, roles, workflows, and no per-user meter.
The catch vs BubbleREI3's utilitarian forms, reports, and pages are a poor substitute for Bubble's highly customized public front ends and interaction design.
Install, platforms & data +
