## 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

## chichi-pui

chichi-pui (affectionately known as 'chichi-pui') is a Japanese community platform built entirely around AI-generated imagery. Members upload AI illustrations, AI photos and AI manga, tag them, and share the prompts behind each piece, so the site doubles as a living prompt library that anyone can search by model or tag.

Beyond the gallery, the platform offers its own in-browser generation tools. Users can create images directly with models such as Stable Diffusion, Stable Diffusion XL, niji-journey, NovelAI, FLUX, ChatGPT and DALL-E-style engines, and the site periodically opens limited-time models through its 'UL' generation feature. A model marketplace, the 'Magoroku Library' of prompt guides, and the chichi-pui shop round out the ecosystem.

The service is run by a Japanese operator and monetised through in-site coins and monthly plans, with community activities such as user-hosted posting events, themed collections and daily/weekly/monthly rankings keeping engagement high. It is free to browse and post, with paid elements for extra generation and shop purchases.

**Pricing & Plans:** Free to browse and post; paid elements include in-site coins, a monthly subscription plan (reintroduced in October) and shop/marketplace purchases.

- **AI image posting gallery:** Upload and browse AI illustrations, photos and manga across illustration, photo and manga sections.
- **Prompt (jumon) sharing and search:** Every post can carry its prompt text, and visitors can search prompts by tag or by which model produced the image.
- **Built-in AI image generation:** Generate images in the browser with Stable Diffusion, SDXL, NovelAI, niji-journey, FLUX and other supported models.
- **Limited-time UL models:** Fresh models are periodically opened through the UL generation feature for a limited period.
- **Rankings, events and shop:** Daily/weekly/monthly rankings, user-hosted posting events, a model marketplace and the chichi-pui shop.

**Strengths:** Huge, highly active gallery with prompts attached to most posts; Generation tools and a prompt database live in the same place; Rich community features: events, collections, rankings and comments; Free to browse and post, with paid extras only when you want them

**Limitations:** Interface and content are primarily Japanese; The most advanced generation models are gated behind coins or a subscription; Some categories contain mature or adult-oriented artwork
