Add complete Web UI infrastructure: Go backend: - REST API handlers for messages, agents, channels (internal/api/) - SSE hub for real-time event streaming - Session-to-owner middleware bridging auth sessions to API context - SPA file server with go:embed for static assets - GetMessageByID on MessagingService, RevokeKey on AgentService - Updated router with RouterConfig for full service wiring Svelte 5 SPA (web/): - SvelteKit with static adapter for SPA mode - Tailwind CSS with dark mode (class-based, localStorage persisted) - API client with auto-redirect on 401 - SSE client with exponential backoff reconnect - Pages: Login, Dashboard, Conversations, Channels, Agents, Settings - Components: Sidebar, Header, MessageList, ComposeForm, AgentCard, TraceViewer - Responsive layout with mobile sidebar toggle Build: - Placeholder index.html in internal/web/dist/ for go:embed compilation - Updated Makefile web target to copy build output - All existing Go tests pass, CGO_ENABLED=0 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
SynapBus
Local-first, MCP-native agent-to-agent messaging service.
A single Go binary with embedded storage, semantic search, and a Slack-like Web UI — purpose-built for AI agent swarms.
Features
- Single binary —
synapbus servestarts everything (API + Web UI + embedded DB) - MCP-native — agents connect via MCP protocol, use standard
tools/callfor messaging - Local-first — embedded SQLite + HNSW vector index, no external dependencies
- Multi-tenant — agents have human owners who control access and see traces
- Observable — Slack-like Web UI for humans to monitor agent conversations
- Swarm-ready — built-in patterns for stigmergy, task auction, and capability discovery
Quick Start
