llampart v2: open-source local LLM chat UI with charts, Mermaid and MCP support
mossy_troll_84 · reddit · 2026-10-21
The developer of llampart released v2.0.1, a self-hosted, desktop-focused open-source chat UI for local LLMs, built with Svelte 5/SvelteKit and grown well beyond its llama.cpp UI origins.
Highlights:
- Supports llama-server (llama.cpp), vLLM and OpenAI-compatible APIs; v2 differentiates providers, protocols (Chat Completions/Responses) and model capabilities
- Conversations stored locally in IndexedDB — no accounts, no cloud; branching, pinning, search, import/export
- MCP integration, tool calling, multi-step agent workflows; reasoning controls adapt per model/provider
- New: AI-generated interactive charts in chat (Line/Area/Bar/Donut, exportable to PNG/SVG/CSV) plus Mermaid flowcharts, state diagrams, mindmaps and Gantt charts
- Response preferences for consistent formatting without repeating prompts
- Frosted glass theming and six UI languages
