Rather than installing a heavy modeling suite with database access, it asks you to run one read-only query per DBMS — the project publishes a ready-made query for PostgreSQL, MySQL, MariaDB, SQL Server, SQLite, ClickHouse, CockroachDB, Oracle, Snowflake, and BigQuery. Paste the output JSON and you get a full, interactive ER diagram that you can rearrange, annotate, and export. Beyond visualization, ChartDB works as an editor. You can add tables, subject areas, and sticky notes, edit relationships, use a DBML editor for text-driven modeling, and produce clean DDL scripts in your preferred SQL dialect. The AI ER diagram generator goes the other direction: describe what you want and get an editable, optimized schema draft. Diagrams are also exportable as images or embeddable previews for docs and wikis. The project is open source under AGPL and has accumulated tens of thousands of GitHub stars, which is why a self-hosted deployment is available alongside the Cloud product. Cloud plans add real-time collaborative editing, database auto-sync that keeps diagrams current as the schema changes, change logs and versioning, and an AI assistant. Teams get multi-user workspaces, 2FA, and priority support; larger organizations can request custom SSO and RBAC terms. **Pricing & Plans:** ChartDB offers a genuinely free open-source tier (self-hosted, AGPL) that includes all core features and up to two diagrams. Cloud plans run about US$25/month for a single user (Pro) and US$59/month for teams, with annual billing discounts of up to 40%. Custom enterprise pricing covers SAML SSO and granular permissions. - **One-query schema import:** Paste a single read-only query result and ChartDB renders the whole schema as an ER diagram, with no direct database access or local agent required. - **AI ER diagram generator:** Describe a database idea in plain language and get a fully editable, optimized ER diagram that you can refine and export straight to SQL. - **DDL and diagram export:** Export clean DDL scripts in your preferred SQL dialect or download diagrams as images and embeddable previews for documentation. - **Auto-sync and versioning:** On Cloud plans, diagrams stay in sync with the live database automatically, with change logs and version history to track every schema drift. - **Real-time collaboration:** Invite teammates to view and edit diagrams simultaneously, with multi-user workspaces and 2FA on team plans. **Strengths:** Truly open source with a generous free self-hosted option and no database access needed; Fast setup — a single query gets you a complete interactive diagram in seconds; Broad DBMS coverage including PostgreSQL, MySQL, SQL Server, SQLite, ClickHouse, Snowflake, BigQuery, and Oracle; AI generation works both ways: prompt-to-diagram and diagram-to-DDL **Limitations:** Cloud collaboration, auto-sync, and the AI assistant are paid; the free self-hosted tier limits you to two diagrams and ten tables each; Snowflake and BigQuery support sits on higher-tier plans; As a specialized ERD tool it does not replace a full data-governance or lineage platform [Profile (Markdown)](https://openaitools.app/tool/chartdb.md) ## n8n n8n is a workflow automation platform built for technical teams who want automation they can actually read and audit. Rather than hiding logic behind opaque configuration, every step stays open: you can see what a node does and explain the whole flow to whoever runs it. It combines a drag-and-drop visual builder with the ability to drop into code at any point, so simple tasks stay simple while complex ones remain possible. A major focus of the current product is AI agents. You can connect any model, watch an agent work step by step in the same workflow view, open past runs, and constrain behaviour with structured inputs and outputs, rule-based automation and human-in-the-loop approval gates. That makes it practical to put agents into processes like refund handling, alert triage, lead qualification and security investigation without losing control. n8n is open source and can be self-hosted on-prem or with Docker to keep data in your own environment, or used as a hosted service. Enterprise capabilities add SSO with SAML and LDAP, RBAC, encrypted secret stores, audit logs, log streaming to SIEM systems, isolated environments and Git-based control. Integrations span 500+ native services, arbitrary HTTP APIs and MCP connections to agents and coding assistants. **Pricing & Plans:** n8n offers a free self-hosted open-source edition, a paid cloud service with a free trial, tiered paid plans, and enterprise pricing on request. Feature limits scale with plan tier, so check the official pricing page for current details. - **Visual builder with code escape hatch:** Build automations with a visual node editor, then insert JavaScript or Python code nodes when you need custom logic. - **500+ integrations and any API:** Connect to 500+ native services, any REST API via HTTP nodes, and any agent or coding assistant through MCP. - **AI agents you can follow and trust:** Run agents alongside regular steps, inspect every decision, and add structured inputs, guardrails and human approval steps. - **Observability and reproducible runs:** Watch workflows execute live, open past runs, replay a run with mocked data and re-run just the step that failed. - **Self-host or cloud with governance:** Deploy on your own infrastructure with Docker or on-prem, or use the hosted cloud product, with version history and RBAC. **Strengths:** Open source and self-hostable, keeping data in your own environment; Visual builder plus full code access for complex workflows; Strong observability: live runs, past-run inspection and step-level retries; 500+ integrations and generic HTTP nodes cover almost any service [Profile (Markdown)](https://openaitools.app/tool/n8n.md) ## Frequently Asked Questions ### How do ChartDB and n8n compare in monthly traffic?
