Bubble alternatives: 8 open-source picks
Bubble costs $59/mo — $708 a year. These 8 alternatives replace it for $0, led by Budibase, NocoBase and Corteza. All 8 are open source. License, stars and last commit checked by hand on 2026-08-29. No trials, no crippled tiers.
Custom web apps with data, forms, screens, and automations; design freedom is far below Bubble's.
licenseGPL-3.0
runsyour server
installDocker image or Docker Compose; Kubernetes is also supported
enginesModel-agnostic; the agent builder supports bring-your-own AI provider credentials
dataBuilt-in app data and app definitions are stored in CouchDB, files in MinIO/S3-compatible object storage, and connected external data remains in its source system
the catch vs BubbleBudibase's component and layout system is optimized for internal business screens and is far less flexible for polished public consumer interfaces than Bubble.
setupRequires Docker and persistent storage; production use also means owning upgrades, TLS, backups, and database/network access
facts verified 2026-08-10
A full database-backed web-app builder with pages, roles, actions, workflows, and plugins; more business app than consumer startup.
licenseNocoBase Community
runsyour server
installNocoBase CLI or Docker deployment with MySQL, MariaDB, or PostgreSQL
enginesBuilt-in AI employees can connect to common LLMs; exact provider support depends on installed AI plugins
dataBusiness data lives in standard relational tables in the configured MySQL, MariaDB, or PostgreSQL database; files use configured local or object storage
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.
setupRequires a database, secrets, and deployment administration; the community license also preserves NocoBase branding and restricts some uses
facts verified 2026-08-10
A self-hosted business-app suite with records, pages, workflows, charts, and enterprise-grade amounts of configuration.
licenseApache-2.0
runsyour server
installDocker Compose with a configured MySQL or PostgreSQL database
dataRecords and configuration live in the configured SQL database; uploaded attachments live in the server persistence directory
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.
setupDocker, a database, secrets, persistent-volume permissions, and a reverse proxy/TLS are the first operational hurdle
facts verified 2026-08-10
Forms, lists, workflows, and role-aware apps from a product old enough to have survived several no-code fashions.
licenseGPL-3.0
runsyour server
installDownload the Community Edition bundle or deploy its Docker image/on-premises package
dataApplication definitions, workflow state, and records live in the configured relational database; uploaded files live on the Joget server
the catch vs BubbleJoget excels at forms and workflows but cannot approach Bubble's freedom for bespoke public-facing layouts, interactions, and responsive design.
setupThe first real hurdle is administering a Java web stack and database rather than clicking through a managed signup
facts verified 2026-08-10
A sober business-app builder with forms, reports, roles, workflows, and no per-user meter.
licenseMIT
runsyour server
installNative Linux/Windows server package or Docker Compose, connected to PostgreSQL
dataHuman-readable application records and configuration live in a PostgreSQL database controlled by the operator
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.
setupYou must provision PostgreSQL and configure a server/reverse proxy; it is not a managed one-click workspace
facts verified 2026-08-10
Turns any database into a smart spreadsheet with grid, kanban, and form views

Bubble FreeA development sandbox with no live production site; the core job begins when you pay.
SaltcornIt does the job, but its own security page lists fresh critical RCE, SQL injection, path-traversal, and cross-tenant bugs.
how to choose a Bubble alternative
Easiest to get running
Joget Community Edition — a one-click install, no server to maintain.
Most proven
NocoDB, with 64,000 GitHub stars — the largest community of the 8, which usually means more answers when something breaks.
Works on your phone
REI3 has a mobile app on iOS and Android.
Needs real ops to self-host
Corteza is capable but expects someone to run a server, updates and backups. Budget for that before choosing it.
what you give up by leaving Bubble
- visual editor
- workflow builder
- plugin marketplace
- hosting/scaling
- nondeveloper maintenance
- templates
None of the picks above covers all of it. The full verdict says which gaps matter.
