Tooljet V2

ToolJet is the open-source Retool alternative — build internal admin panels, CRUD apps, and dashboards with a visual editor, connect to 50+ data sources, and deploy self-hosted. For agents: ToolJet Workflows can be triggered via REST API (POST /api/v2/workflows/{workflow_id}/execute) to run automated sequences (database queries, API calls, conditional logic, notifications) without embedding that logic in the agent. Free and open-source self-hosting on Docker or Kubernetes. 34k+ GitHub stars signals strong community. Confidence is docs-derived.

REST API at {tooljet_host}/api. Trigger workflow: POST /api/v2/workflows/{workflow_id}/execute body: {"params": {"key": "value"}}. Response: {"status": "success", "data": {...}}. Apps: GET /api/apps lists apps. GET /api/apps/{app_id} retrieves app details. Data sources: GET /api/data_sources lists configured data sources. Users: GET /api/users lists organization users. ToolJet components: built in visual editor (drag-and-drop React components). Queries: database/API queries defined in the editor; run via component events or workflow steps. Workflow trigger: workflows can be triggered on schedule (cron) or via webhook URL (POST to /api/v2/workflows/{id}/webhook). JavaScript in ToolJet: write JS in query/transform steps for data manipulation.

API key auth: Authorization: Bearer {api_key}. Keys from ToolJet → Profile → API Keys. HTTPS enforced in ToolJet Cloud; self-hosted: configure TLS. RBAC: workspace roles (admin, builder, end-user) + app-level permissions. SSO: SAML/OIDC on Enterprise plan (Okta, Azure AD, Google Workspace). No OAuth2 for ToolJet API. Self-hosted: manage your own auth configuration via TOOLJET_HOST + database config. Workflow webhooks: HMAC signature for webhook security.

Workflow runs: synchronous (returns result when complete) or async (with webhook callback). Workflow timeout: configurable (default 30s; extend for long-running tasks). API rate limits: apply per plan on ToolJet Cloud; no limits on self-hosted. Self-hosted reliability: ToolJet recommends PostgreSQL for persistence; Docker Compose for dev, Kubernetes for production. Large data: ToolJet processes data in-memory for workflow steps — use database-side aggregation for large result sets. ToolJet Cloud uptime: status.tooljet.com.

docs.tooljet.com covers UI builder guide, data source setup, workflow automation, REST API reference, and self-hosting. Getting started (self-hosted): docker-compose up — ToolJet running in under 5 minutes. ToolJet Cloud: free tier (5 apps, 5 users). Enterprise: SAML SSO + audit logs. GitHub: ToolJet/ToolJet (34k+ stars). Community via GitHub Discussions and Slack (active). Thorough documentation; open-source nature means extensive community guides.
