## 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

## draft1.ai

draft1.ai targets engineers and technical writers who need diagrams but don't want to hand-place boxes in a drawing tool. You paste rough notes, a Slack thread, an SQL schema, a Terraform module or a docker-compose file, and the service returns a structured diagram plus a short written report explaining components and data flow. Supported diagram families include ER diagrams, UML, flowcharts, network diagrams, cloud infrastructure and Kubernetes architecture.

The key differentiator is the editing story. Every generated diagram is delivered as a draw.io file, so you can open it in draw.io or Visio, nudge elements, recolour them, or hand it to a colleague for review. Diagrams can also be exported as PNG for slides, and the accompanying document as PDF, DOCX or Markdown.

Pricing is subscription-based with a free entry point: a demo that needs no signup, followed by three free diagrams once you create an account. Paid tiers are aimed at individuals (Basic), professional writers (Pro) and larger organisations that need version control via GitHub and collaboration (Enterprise).

**Pricing & Plans:** Free demo without signup plus 3 free diagrams with an account. Paid plans start at about $24/month for individuals, $32/month for professionals, and $99 per user/month for enterprise features such as GitHub version control and collaboration. No credit card is required for the free tier.

- **Text and code to diagram:** Describe a system in plain English or paste Terraform, docker-compose or SQL and receive a structured diagram in about 20 seconds.
- **draw.io and Visio compatible output:** Generated diagrams are editable files, not flat images, so you can keep refining them in the tools your team already uses.
- **Multiple diagram libraries:** Dedicated templates for ER diagrams, UML, flowcharts, network diagrams, cloud infrastructure and Kubernetes architectures.
- **Diagrams plus written report:** Alongside the visual, draft1.ai drafts a short document covering components, data flow and security considerations.
- **Multi-format export:** Download assets as PNG for presentations or DOCX, PDF and Markdown for documentation and publishing.

**Strengths:** Fast turnaround: rough notes become a usable diagram in about 20 seconds; Output stays editable in draw.io and Visio instead of being a static image; Handles both natural-language prompts and real infrastructure code; Free tier is genuinely usable: a no-signup demo plus three free diagrams

**Limitations:** Subscription pricing may feel steep for occasional diagram needs; Complex or highly stylised diagrams may still need manual cleanup; Enterprise collaboration and GitHub version control are listed as coming soon
