Enterprise knowledge is trapped in silos. Digital tools (Slack, GitHub, Notion, Gmail) don't talk to physical systems (IoT sensors, industrial protocols, camera feeds). **OpenBeam unifies both into one searchable, agent-ready layer.** One query across sensors and SaaS. Answers in 200ms. Runs on your servers.

Glean proved the digital half at a $7.2B valuation. Nobody has built the physical half. We're building both.

## Features

- **Unified Search** — Hybrid semantic + keyword search across all connected sources, sub-200ms p99 latency
- **AI Agents** — Tool-use agents that search, analyze, and act across your entire knowledge base with 100+ composable tools
- **Computer** — Six pre-built autonomous agents on Temporal cron schedules with approval gating and persistent memory
- **Physical + Digital** — The only platform bridging SaaS tools and physical operations data in one query
- **87 Connectors** — Slack, GitHub, Notion, Linear, Salesforce, Jira, Gmail, plus IoT (Samsara, Verkada, AWS IoT) and industrial protocols (MQTT, OPC-UA, BACnet)
- **MCP Server** — First-class Model Context Protocol server for Claude Code, Cursor, Codex, and any MCP client
- **RAG Pipeline** — Grounded AI answers with citation and source attribution
- **Real-time Sync** — Webhooks and incremental sync keep your index fresh
- **Permission-Aware** — Respects source permissions — users only see what they have access to
- **Self-Hostable** — Deploy on your infrastructure with Docker Compose. Your data never leaves your servers
- **Edge Ready** — Offline-capable edge deployment with SQLite, local search, and sync protocol

## Install the CLI

Cross-platform Go binary, signed with cosign, with SLSA Level 3 build provenance.

```bash
# macOS — Homebrew
brew install kuluruvineeth/tap/openbeam

# Linux / macOS — curl
curl -fsSL https://openbeam.work/install.sh | bash

# Windows — Scoop
scoop bucket add openbeam https://github.com/kuluruvineeth/scoop-bucket
scoop install openbeam

# Docker
docker run --rm ghcr.io/kuluruvineeth/openbeam-cli:latest version
```

Or download `.deb`, `.rpm`, `.apk`, Arch, or platform binaries from the [latest release](https://github.com/kuluruvineeth/openbeam/releases/latest).

```bash
openbeam auth login --api-key op_live_xxx
openbeam search query "kubernetes upgrade runbook"
openbeam upgrade           # self-update
openbeam doctor            # diagnose install + auth + connectivity
openbeam computer run knowledge-digest --wait
```

## Computer — Autonomous Agents

Six pre-built agents that run on a schedule, ask for approval before any write, and remember context across runs.

| Agent | What it does |
|---|---|
| **Knowledge Digest** | Weekly summary of new content across every connected source |
| **Stale Content Detector** | Flags docs older than 90 days for archival or refresh |
| **Connector Health** | Watches sync failures and re-auths expiring OAuth tokens |
| **Search Quality** | Audits failed queries and proposes connector + index fixes |
| **Onboarding Curator** | Generates personalized reading lists for new hires |
| **Compliance Watchdog** | Alerts on exposed credentials or PII in indexed content |

Each agent is durable via Temporal, multi-surface (CLI / Dashboard / Chat / API / MCP), and approval-gated for any third-party write action. Custom agents are defined by a prompt and a tool list.

```bash
openbeam computer enable knowledge-digest --schedule "0 9 * * MON"
openbeam computer run knowledge-digest --wait
openbeam computer approve <run-id> --actions "archive,notify"
```

[Computer documentation →](https://docs.openbeam.work/computer)

## Quick Start

```bash
git clone https://github.com/kuluruvineeth/openbeam.git
cd openbeam
make setup    # Install deps, start infra, setup database
make apps     # Start all apps with hot reload
```

Open [http://localhost:3001](http://localhost:3001) and you're in.

### Self-Hosting with Docker

```bash
docker compose -f docker-compose.infra.yml -f docker-compose.yml up -d
```

See the [Self-Hosting Guide](https://docs.openbeam.work/docs/self-hosting) for configuration, TLS, monitoring, and scaling.

## Why Open Source?

Enterprise search touches your most sensitive data — every message, document, sensor reading, and credential. You should be able to read every line of code that processes it.

AGPL-3.0 licensed. Self-host it, audit it, extend it. No vendor lock-in. No data leaving your network.

## Contributing

We welcome contributions. See [CONTRIBUTING.md](./CONTRIBUTING.md) for guidelines.

```bash
git clone https://github.com/YOUR_USERNAME/openbeam.git
cd openbeam
make setup && make apps
```

Connectors are the fastest path to a merged PR — each takes about 2-3 hours. Check the [`good first issue`](https://github.com/kuluruvineeth/openbeam/labels/good%20first%20issue) label to get started.
