Open-source database diagram editor with AI-generated ER diagrams
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.
Describe a database idea in plain language and get a fully editable, optimized ER diagram that you can refine and export straight to SQL.
Export clean DDL scripts in your preferred SQL dialect or download diagrams as images and embeddable previews for documentation.
On Cloud plans, diagrams stay in sync with the live database automatically, with change logs and version history to track every schema drift.
Run and build with open AI models locally or in the cloud
Install once and pull open-weight models by name; Ollama handles weights, quantization and versioning for you.
A built-in server exposes a straightforward REST API, so scripts, editors and agents can talk to local models with minimal setup.
Route requests to hosted open models when your laptop cannot hold the checkpoint you need, with per-token pricing and concurrency tiers.
Access families such as Llama, Qwen, DeepSeek, Gemma, Mistral and gpt-oss from a single interface.
