The other three things it does.
Diagrams are the front door. These are the rooms behind it.

- Local-First AI Coding AgentSame agent core in a native desktop app and a 6 MB Rust binary, running whichever model you choose, including one on your own laptop.
- Local LLM Coding AgentFor when the constraint is not cost but that the code cannot leave the building.
- Diagram-Driven DevelopmentThe diagram stops being documentation produced after the fact and becomes the instruction the code is written from.
- Terminal Coding AgentOne binary, no runtime, no browser. Free and open source.
- AI Assistant for ObservabilityWorth being precise about what this is: it drives the observability tools you already run. It is not an LLM tracing platform, and if that is what you searched for, the tools below are the right ones.
- AI Assistant for GrafanaThe value is not writing the query. It is going from the query result to the line of code without leaving the session.
- PromQL Query AssistantPromQL is not difficult, it is just impossible to remember the exact shape of a rate over a histogram at the moment you need it.
- Loki Log Analysis with AIFinding the log line is half the job. The other half is working out what emitted it and why.
- AI Design Canvas for SoftwareWorth saying plainly: this designs the structure of an application, not its interface. If you want polished UI mockups, the tools below are better.
- App Wireframe GeneratorLow fidelity on purpose. A wireframe that looks finished gets reviewed as a design instead of as a structure.
- User Flow Diagram GeneratorThe value is in the branches you had not thought about, which is exactly what drawing the flow forces you to name.
- AI Short Video from Your DiagramsA narrow feature with a specific use: explaining a system to people who will not read a diagram.
Elsewhere
- System Design TemplatesEach template is a real diagram produced by the same layout engine the app runs, not a picture of one.
- Generate a Diagram from Your CodeEvery source below lists the exact files it reads and the constructs it maps to diagram nodes.
- AI Diagram GeneratorsThe agent emits a semantic graph and ELK computes the layout, so overlapping boxes are structurally impossible.
- Compare Lucid TrainEvery page says what the other tool is better at. If that section were empty the comparison would not be worth reading.
- Convert Code and DiagramsEvery conversion page states what survives the round trip and what does not.
- Use CasesEach page includes who it is not for, which is usually the more useful half.
