Open source alternative to Retool, UI Bakery, Jet Admin, Superblocks and DronaHQ

Build internal tools and customer-facing apps with 120+ drag-and-drop components, self-hosting on Docker, and an AGPL-3.0 license.
Connect existing PostgreSQL, MySQL, or MongoDB databases, place table and form components, configure filters and action buttons, and ship a working admin panel in hours. Changes take effect without a deploy step or build cycle, so iterating on feedback is fast.
If your admin requirements are met by an existing BI tool or a simple CRUD interface, Lowcoder's setup overhead may outweigh its value for a one-off panel.
Build dashboards, CRM views, inventory tools, and ticketing interfaces on your own infrastructure. The per-instance enterprise pricing means adding more users does not increase the license bill, making Lowcoder cheaper than per-seat tools as team size grows.
If your organization resists managing container infrastructure, the operational overhead of running Lowcoder may outweigh the savings over per-seat commercial tools.
Design customer-facing forms, onboarding workflows, and self-service portals. The native embedding SDK lets you drop a Lowcoder app into a client's existing website without an iFrame, so the portal keeps the host site's styling and URL structure.
If a client needs a fully bespoke UI with no shared component framework, hand-coded React will give tighter control than any visual builder.
Build student administration tools, enrollment forms, and cross-department workflows on a single visual builder. Southern Methodist University uses Lowcoder in production for campus-wide administrative and public-facing apps under a tool they call Webframe.
If your institution has procurement rules around AGPL-licensed software or requires vendor support SLAs, review Lowcoder's enterprise contract options before adopting at scale.
Building internal tools is expensive when done from scratch and costly when rented from commercial services. Retool, Superblocks, and similar tools charge per seat, so a tool used by 50 internal staff quickly runs into thousands of dollars per month. For teams with data privacy requirements, the cloud-only constraint of most commercial services is a separate blocker: sensitive operational data cannot leave the organization's infrastructure.
The technical effort to build even a basic admin dashboard without a low-code tool is high. Frontend developers must wire up databases, design component layouts, handle state, and manage updates manually. Most internal tools don't justify that investment, so teams either build shortcuts that break, or pay commercial licensing they outgrow.
The component library includes form inputs, tables, charts, kanban boards, and specialized widgets for rapid app development. Components are configured visually without writing layout code, and custom components can be built as plugins and published to npm under the lowcoder-comp namespace for community sharing.
Connects to PostgreSQL, MySQL, MongoDB, Redis, Elasticsearch, REST APIs, SMTP, and more. Connections are configured in the visual builder and query results bind directly to component properties. WebSocket data sources enable real-time streaming updates so apps reflect live data without manual refreshes.
Lowcoder apps embed directly into external HTML pages and React apps using the native SDK, without an iFrame wrapper. The embedded app can share CSS context with the host page and communicate through defined JavaScript interfaces. Most low-code tools use iFrame embedding, which creates hard style and communication boundaries.
WebRTC-based video meeting components let teams build conferencing tools inside a Lowcoder app. Meeting sessions sit alongside other app panels, so users can discuss a case, update its records, and take action without switching to a separate tool.
RBAC governs who can view, edit, or administer apps and data sources within a workspace. Permissions are managed per workspace through member groups, so teams can scope access to the right people without sharing credentials or exposing configuration.
Component groups that repeat across apps are saved as modules and re-embedded without copying configuration. The query library stores reusable data queries the same way, reducing duplication when multiple apps connect to the same databases or APIs.
Both target internal tool development and share a drag-and-drop builder, but differ sharply on hosting model and pricing. Retool is a proprietary service with self-hosting available on paid tiers only; Lowcoder is AGPL-3.0 open source with self-hosting as the primary deployment path and no per-user licensing.
| Feature | Lowcoder | Retool |
|---|---|---|
| License | AGPL-3.0 | Proprietary |
| Self-hosting | Yes (Docker, Helm) | Yes (paid tiers) |
| Pricing model | Per instance | Per user |
| Native site embedding | Yes (no iFrame) | No |
| Video meeting components | Yes | No |
Lowcoder is the better choice when your team has a large internal user base, when data privacy rules prevent sending queries through a third-party cloud, or when you need to embed an app natively in a customer-facing site. Retool is worth considering when you need its broader integration ecosystem and a managed cloud with uptime guarantees that Lowcoder does not yet match.
Superblocks is a newer commercial tool for internal apps and automations, cloud-first with self-hosting on paid plans. Lowcoder differs in its AGPL-3.0 license, per-instance pricing, and broader scope that includes customer-facing apps and native website embedding.
| Feature | Lowcoder | Superblocks |
|---|---|---|
| License | AGPL-3.0 | Proprietary |
| Self-hosting | Yes (free) | Paid plans |
| Component count | 120+ | Fewer |
| Native embedding | Yes (no iFrame) | No |
Lowcoder is the better fit when you need self-hosting and cannot absorb per-user licensing. Superblocks is worth considering when automation workflow tooling is a core need and your team prefers a fully managed service with dedicated support.
UI Bakery is a no-code/low-code internal app builder with a hosted cloud and an on-premise paid option, but it is a proprietary commercial service, not open source.
| Feature | Lowcoder | UI Bakery |
|---|---|---|
| License | AGPL-3.0 | Proprietary |
| Self-hosting | Yes (free) | Yes (paid) |
| Component count | 120+ | Comparable |
| Public apps | Yes | Limited |
Lowcoder is the better fit when source access and free self-hosting are requirements, or when you need to build customer-facing apps alongside internal tools. UI Bakery is worth considering for teams that want a polished managed cloud with vendor support contracts.
The community edition is free and runs on your own infrastructure with no seat limits. A free community cloud is also available at app.lowcoder.cloud. The enterprise edition starts at €459 per instance per month or €4,990 per year, priced per instance rather than per user. AI and support services are billed separately.
Lowcoder is AGPL-3.0 licensed. You can run it on your own servers, modify it, and use it commercially for internal teams without restriction. If you modify the source and offer it as a hosted managed service to external customers, AGPL-3.0 requires publishing those changes. The enterprise edition is also AGPL-3.0, not a separate proprietary tier.
Lowcoder is AGPL-3.0 open source with per-instance enterprise pricing; Retool is a proprietary service with per-user billing. Lowcoder supports native website embedding without an iFrame and includes video meeting components that Retool does not offer. Retool has a more mature integration ecosystem and a managed cloud with uptime guarantees that Lowcoder does not yet match.
Yes. Lowcoder has a React-based native embedding SDK that lets you embed an app directly in any HTML page without an iFrame. The embedded app can communicate with the host page through defined JavaScript interfaces. This differs from most low-code tools, which rely on iFrame embedding and face hard CSS and communication boundaries.
Lowcoder supports Docker Compose for single-server deployments and Helm Charts for Kubernetes environments. The official documentation at docs.lowcoder.cloud describes a five-minute Docker install path. A free community cloud is also available for teams that prefer not to manage their own infrastructure.
