Dates reflect when each change reached the product. Some larger initiatives roll out gradually
behind feature flags, so an item may appear here shortly before it becomes visible in your workspace.
Pressing Cmd+I drops the node you have selected straight into the Lab Agent chat.
Blueprints move to a LogicFlow-JSON storage format for quicker loads and saves.
Every version of a project becomes a change you can inspect, compare, and restore — with a stream-aware graph that shows drafts forking from and merging back into main, and View conversation to reopen the Lab Agent chat behind any change. See Timeline.
Pick a change workflow per project: apply edits directly, or hold them on a draft and gate delivery to main with reviewers and approval rules — four-eyes approval, passing tests, resolved comments, and more.
The Lab Agent answers questions and edits your Blueprint from a chat panel beside the canvas.
Foundations for self-hosted, enterprise deployments.
An agent that runs your Blueprints and tests, reads and writes your types, and creates and renames Blueprints — with approval and speed/quality modes.
Value and data types as a first-class, business-readable layer.
Share a project via link; viewers can copy it, and anonymous
/try works without an account.
The unified Specification View: Contents, Type Definitions, Inputs & Outputs, and embedded Blueprints in one document.
Build reusable test cases and run them from the editor or CLI, plus a VS Code extension with Veritas highlighting.
Natural-language operators —
and/or, is/isnt, not, and absent — plus execution traces distributed across the diagram.In-process execution from the CLI, plus an MCP tool that renders a Blueprint viewer.
