Budibase
open sourceGPL-3.0Self-host28kjul 2026Internal apps, forms, automations, and portals in one box; much closer to Knack than its developer branding suggests.
The catch vs ToolJet CloudBudibase can replace the CRUD interface but gives up ToolJet Cloud's managed hosting and makes the user responsible for Docker, upgrades, backups, and availability.

- platforms
- webself-hosteddocker to self-host
- install
- Docker image or Docker Compose; Kubernetes is also supported

- Requires Docker and persistent storage; production use also means owning upgrades, TLS, backups, and database/network access
- engines
- Model-agnostic; the agent builder supports bring-your-own AI provider credentials
- your data
- Built-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

Lowcoder
open sourceAGPL-3.0Self-host1.6kjul 2026A self-hosted internal-tool canvas with a broad widget set; less polished, but not a toy.
The catch vs ToolJet CloudLowcoder is capable but noticeably less polished and documented, and self-hosting shifts all production operations away from ToolJet Cloud.
Install, platforms & data +
- platforms
- webself-hostedself-host, real ops
- install
- Single Docker image for evaluation, or Docker Compose/Helm with separate MongoDB and Redis services for production
- setup
- Docker is required; a production deployment needs MongoDB, Redis, secrets, backups, TLS, and more care than the all-in-one demo image
- engines
- Connectors include OpenAI and other APIs; the operator supplies provider credentials
- your data
- Users, app definitions, data-source configuration, and assets live in the deployment's MongoDB and mounted lowcoder-stacks volume; Redis holds sessions/state; external business data stays in its source

Appsmith Free
freeApache-2.0HostedFive people can build and run database-backed internal apps in the hosted product without paying.
The catch vs ToolJet CloudAppsmith Free is less generous for a tool with many end users and its hosted component and permission model differs enough to require rebuilding the app.
Install, platforms & data +
- platforms
- webthey host it
- install
- Hosted signup for Appsmith Cloud Free
- engines
- Appsmith's AI/agent features use Appsmith-managed AI services; exact model availability is product-controlled rather than a local backend
- your data
- App definitions, users, and secrets live in Appsmith Cloud; connected business data remains in the source database/API, while query results pass through Appsmith

Retool Free
freeproprietary, freeHostedThe paid app's real builder, database, mobile apps, and 500 workflow runs for up to five people at $0.
The catch vs ToolJet CloudRetool Free's tiny team allowance makes it unsuitable for the many-viewer internal tools that ToolJet's free and paid plans are designed to serve.
Install, platforms & data +

- Hosted signup in Retool Cloud
- engines
- Retool-managed AI models and agents; Free includes pooled AI credits and limited agent hours, while bring-your-own model keys are plan-dependent

ToolJet Free
freeAGPL-3.0HostedThe same cloud product is free for two builders, 50 end users, two apps, five database tables, and unlimited external data sources.
The catch vs ToolJet CloudIt is the same service with caps on builders, apps, database tables, AI, and advanced governance, so a paid deployment may not fit without redesign.
