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.
Serverless cloud infrastructure for AI and data workloads
Write plain Python, attach GPUs or containers, and deploy HTTPS endpoints that autoscale with traffic and scale to zero when idle.
Launch isolated, secure environments for coding agents, RL rollouts, and untrusted code, with sub-second starts and support for over a million concurrent sandboxes.
Run fine-tunes, LoRA, full training, and reinforcement learning on elastic single or multi-node GPU capacity with no quota requests.
Serve LLMs and image, video, or audio models through OpenAI-compatible endpoints, or bring your own inference stack and let Modal handle the infrastructure.
