## 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

## T3 Code

T3 Code is an open-source application for developers who juggle more than one AI coding agent. Instead of switching between terminals, editors and vendor dashboards, it provides one surface where threads with Claude Code, Codex, Antigravity, OpenCode, Cursor and Grok can run side by side. Critically, the project does not resell model tokens: you plug in the credentials and subscriptions you already have, so your existing plan and quota remain yours. Models can even be switched mid-thread, letting you move a task to a different harness without losing conversation context.

**Pricing & Plans:** Free and open-source. There is no T3 Code subscription; you bring your own existing Claude Code, Codex, Cursor or similar subscription and pay those vendors directly.

- **Multi-Agent Orchestration:** Run Claude Code, Codex, Antigravity, OpenCode, Cursor and Grok sessions side by side in one workspace.
- **Bring Your Own Subscription:** No resold tokens or quota caps — connect the credentials and plans you already pay for, and switch models mid-thread.
- **Git and PR Workflow:** Manage branches, automate commits and pushes, and handle pull requests with inline diff review before accepting changes.
- **Forkable and Self-Hostable:** Open-source and MIT licensed, so you can run it on your own infrastructure and modify it for your team.
- **Desktop and Mobile Access:** Available on macOS, Windows and Linux with iOS, Android and browser connect options for remote machines.

**Strengths:** Free and open source with no vendor subscription for the tool itself; One interface for several major coding agents instead of scattered terminals; Bring-your-own-subscription model with no token reselling or quota caps; Mobile and browser access plus Git, diff review and PR automation built in

**Limitations:** Requires your own paid agent subscriptions to be genuinely useful; Self-hosting and configuration are your responsibility, with community rather than vendor support; Rapidly evolving project means features and stability can shift between releases
