Xyne: Open-Source AI-Powered Enterprise Search and Answer Engine

Xyne is an AI-first search and answer engine designed for workplace data. This TypeScript-based application serves as an open-source alternative to enterprise solutions like Glean, Gemini, and Microsoft Copilot, connecting to workplace applications to index data and provide contextual AI-powered search capabilities.

The platform addresses the fragmentation of work information across multiple SaaS applications, documents, repositories, and communication tools. By securely indexing data from sources like Google Workspace, Atlassian suite, Slack, and GitHub, Xyne creates a unified search experience with AI-generated answers backed by source citations.

Quick Start

The project provides Docker-based deployment for local development and cloud environments:

docker-compose up

Time to first result: ~10 minutes (including Google Workspace integration setup)

For production deployment, the documentation references cloud deployment guides for AWS EC2 and other providers.

Alternative Approaches

Architecture and Implementation

The codebase demonstrates a full-stack TypeScript architecture with distinct frontend and server components. The analysis reveals 186,278 lines of code across 451 files, with TypeScript comprising 166,406 lines.

The OAuth implementation shows a modal-based authentication flow in frontend/src/oauth/index.ts:3-17:

export class OAuthModal {
  // private authUrl: string;
  // private connectorId: string;
  private width: number
  private height: number
  private windowRef: Window | null = null
  private intervalId: number | null = null
  private completed = false // Flag to prevent multiple resolve/reject calls
  private logger = console
  private successUrl: string = ""

  constructor(
    // connectorId: string;
    width?: number,
    height?: number,

The server utilities include timezone-aware date formatting for AI interactions in server/utils/index.ts:3-17:

export function getDateForAI({
  userTimeZone,
}: { userTimeZone: string }): string {
  const today = new Date()
  const day = today.getDate()
  const year = today.getFullYear()

  const options: Intl.DateTimeFormatOptions = {
    month: "long",
    timeZone: userTimeZone || "Asia/Kolkata",
  } // or dynamically detect user's tz
  const monthName = today.toLocaleDateString("en-US", options) // "en-US" is common for full month names

  let daySuffix = "th"
  if (day === 1 || day === 21 || day === 31) {

The test suite reveals sophisticated state management for chat interactions, particularly around “thinking” states during AI processing. The tests in frontend/src/routes/_authenticated/ChatMessage.test.tsx:81-100 demonstrate complex streaming and retry scenarios:

describe("Thinking State Scenarios", () => {
  describe('when response is stopped (even if message becomes empty), "Thinking..." text disappears and action buttons are shown', () => {
    test('it ensures "Thinking..." text disappears and relevant action buttons are shown', () => {
      // 1. Initial render: component is actively streaming/thinking
      const { rerender, getByText, queryByText } = render(
        <ThemeProvider>
          <ChatMessage
            {...baseProps}
            message="" // No final message content yet
            thinking="" // Thinking prop has content
            responseDone={false} // Response is NOT done
            isStreaming={true} // IS streaming
            dots="..." // Dots are present
          />
        </ThemeProvider>,
      )

Performance Characteristics

Bundle Impact:

• Frontend TypeScript: ~166,406 lines
• Server utilities: Timezone-aware date processing with configurable defaults
• Total analyzed codebase: ~186,278 lines

Other Considerations:

• Runtime dependencies: 1 (zustand ^5.0.8 for state management)
• Test coverage: 8 test files identified
• Build tooling: TypeScript-based with Docker containerization

Best for: Organizations needing self-hosted enterprise search with AI capabilities across Google Workspace and other workplace tools.

Deployment and Scaling Considerations

The documentation indicates support for multiple deployment patterns:

• Local development via Docker Compose
• Cloud deployment on AWS EC2 with dedicated guides
• Self-hosted options for on-premises or private cloud environments

The architecture supports model-agnostic LLM integration, allowing connection to various AI providers or local models via Ollama. The system enforces permissions awareness, maintaining existing application access controls during search operations.

Security Architecture

The platform emphasizes security through several mechanisms:

• Self-hosted deployment ensuring data remains within organizational boundaries
• No training on user data or prompts
• No telemetry collection
• Permissions-aware access control maintaining existing application security models
• Service account integration for Google Workspace with documented authentication flows

When to Use Xyne

The evidence suggests this project fits well for:

• Organizations requiring self-hosted enterprise search to maintain data sovereignty
• Teams using Google Workspace extensively who need unified search across drive, calendar, contacts, and Gmail
• Companies seeking open-source alternatives to commercial enterprise search solutions with AI capabilities

Consider alternatives when:

• Simple document search without AI integration is sufficient
• Cloud-hosted solutions are acceptable and budget allows for commercial offerings
• The organization lacks infrastructure expertise for self-hosted deployment and maintenance
