Observable

Observable is a computational notebook and data-app platform for exploring, visualizing, and explaining data with code. Notebooks combine prose, JavaScript, TypeScript, HTML, SQL, live values, interactive inputs, libraries, databases, file attachments, and APIs. Teams can collaborate in real time or through fork-and-merge workflows, publish dashboards and notebooks, manage access, use AI Assist, and connect private data sources.

✨ Key Features

• Write computational notebooks — Interleave prose, code, and visual outputs in one document.
• Analyze and visualize data — Build charts, maps, dashboards, and data apps.
• Use JavaScript, TypeScript, HTML, and SQL — Work with familiar web and data languages.
• Inspect live runtime values — See outputs beside the cells that define them and inspect dataflow.
• Add interactive inputs — Use buttons, sliders, tables, filters, and file inputs.
• Connect data sources — Query databases, attach files, use secrets, libraries, and web APIs.
• Use AI Assist and Observable Chat — Draft or edit code with agent-supported workflows.
• Collaborate in teams — Edit together, comment, fork, merge, and control access.
• Publish and embed work — Share notebooks, dashboards, and data apps.
• Use version control and plain-text files — Keep notebook work portable and inspectable.
• Use open-source libraries — Build with D3, Plot, npm packages, and Observable tooling.
• Manage private workspaces — Enterprise adds authentication, restrictions, file controls, and audit logs.

💳 Pricing

• Free — Individual notebooks with limited daily Agent tokens, 1 GB/month attachments, and watermarked embeds.
• Pro — Individual plan: US$25 billed monthly. Includes 50 compute minutes/month and higher daily Agent tokens.
• Team — Shared workspace: US$45/editor billed monthly. Private viewers cost US$10/viewer/month; this viewer charge belongs to Team, not individual Pro.
