The picks

5 open source Β· ranked by fit

  1. 01

    Budibase

    open sourceGPL-3.0Self-host
    28kjul 2026

    Custom web apps with data, forms, screens, and automations; design freedom is far below Bubble's.

    The catch vs Bubble

    Budibase's component and layout system is optimized for internal business screens and is far less flexible for polished public consumer interfaces than Bubble.

    NocoBase

    open sourceNocoBase CommunitySelf-host
    24kaug 2026

    A full database-backed web-app builder with pages, roles, actions, workflows, and plugins; more business app than consumer startup.

    The catch vs Bubble

    NocoBase is fundamentally a database-backed administrative app builder, so it gives up Bubble's consumer-app design freedom and front-end plugin ecosystem.

    NocoBase CLI or Docker deployment with MySQL, MariaDB, or PostgreSQL

    Corteza

    open sourceApache-2.0Self-host
    2.1kmar 2026

    A self-hosted business-app suite with records, pages, workflows, charts, and enterprise-grade amounts of configuration.

    The catch vs Bubble

    Corteza 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.

    Joget Community Edition

    open sourceGPL-3.0Self-host
    607may 2026

    Forms, lists, workflows, and role-aware apps from a product old enough to have survived several no-code fashions.

    The catch vs Bubble

    Joget excels at forms and workflows but cannot approach Bubble's freedom for bespoke public-facing layouts, interactions, and responsive design.

    REI3

    open sourceMITSelf-host
    571aug 2026

    A sober business-app builder with forms, reports, roles, workflows, and no per-user meter.

    The catch vs Bubble

    REI3's utilitarian forms, reports, and pages are a poor substitute for Bubble's highly customized public front ends and interaction design.
