## ChartDB

ChartDB attacks a familiar annoyance: understanding an unfamiliar or sprawling database schema. 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

## Orca-Tool

Docker Compose files are powerful but unforgiving: indentation, service names, volumes, and dependency links all have to line up, and a long file quickly becomes hard to reason about. Orca takes the opposite approach and presents the same configuration as a visual map of containers and their connections, which is much easier to review and discuss with someone who does not read YAML fluently.

The tool ships with starting points for the stack patterns most teams build first. You can begin from a blank diagram or from a template such as WordPress with MySQL, React with Express and MySQL, Nginx with PHP and MySQL, or a full Elasticsearch stack including Kibana, Logstash, and APM. From there you adjust services, add containers, and reorganise the layout while the file structure follows what you draw.

Because it runs in the browser and works on plain Compose definitions, Orca fits well as a planning and teaching aid: it is a quick way to draft a new environment, to explain an existing one during onboarding, or to sanity-check a stack before committing it to a repository. It is positioned as a free tool with no account requirement implied by the product itself.

**Pricing & Plans:** Orca-Tool is listed as a free tool. No paid tier or pricing page is published on the site, so there is no cost information to quote beyond its free availability.

- **Visual Compose editor:** Represent services and their relationships as a diagram so the shape of a multi-container stack is readable without parsing YAML line by line.
- **Ready-made stack templates:** Start from predefined setups including WordPress with MySQL, React with Express and MySQL, Nginx with PHP and MySQL, and an Elasticsearch stack with Kibana, Logstash, and APM.
- **Blank canvas for custom stacks:** Begin with an empty diagram when your architecture does not match any template and assemble the services yourself.
- **Graphical container orchestration overview:** See how containers, databases, and supporting components fit together before you run them, which helps catch missing links early.
- **Browser-based, no install:** Work directly on the web app, which makes it convenient for quick drafts, demos, and explaining setups to teammates.

**Strengths:** Makes multi-container architecture legible to people who do not read YAML fluently; Includes templates for the most common self-hosted and app stacks; Runs in the browser with nothing to install; Free to use, with no pricing page suggesting a paywall for core editing

**Limitations:** Well suited to planning and documentation rather than heavy production orchestration management; Diagrams can become crowded once a stack grows to many services; Limited published documentation, so some behaviour has to be discovered by trying it
