OpenClaw Architecture Overview (Japanese)

Name Evolution: Clawd.bot → Moltbot → OpenClaw

The project began as Clawd.bot, a proof‑of‑concept chatbot built on a lightweight Node.js runtime. As demand grew, the team rewrote the core in Rust for performance, rebranding the service as Moltbot. The “Molt” prefix highlighted the system’s ability to “molt” new capabilities without downtime. In 2023, after adding a full gateway, memory orchestration, and a marketplace of AI agents, the platform earned its final name: OpenClaw. The “Open” signals open standards and extensibility; “Claw” reflects the modular “claw‑like” hooks that attach agents, data stores, and external services.

Each name change coincided with a major architectural milestone, making the version history a useful roadmap for developers who need to migrate legacy bots. For a quick visual of the transition, see the table below:

Core Architecture Overview

OpenClaw follows a MECE (Mutually Exclusive, Collectively Exhaustive) design that separates concerns into three primary layers:

• Gateway Layer – Handles inbound/outbound traffic, authentication, rate‑limiting, and protocol translation.
• Memory Model – A shared, versioned state store that agents read/write atomically.
• Agent Layer – Pluggable AI or logic modules that process events, query external APIs, or generate responses.

The entire stack runs inside Docker containers orchestrated by Web app editor on UBOS, which provides a visual workflow canvas and one‑click deployment.

Gateway Design

The gateway is built on actix‑web (Rust) and supports HTTP, WebSocket, and gRPC. Its responsibilities include:

1. Authentication via JWT, API keys, or OAuth2.
2. Dynamic routing based on /api/v1/{agent_name} patterns.
3. Rate‑limiting per tenant to protect shared resources.
4. Payload validation using JSON Schema.

For developers who need real‑time chat, the gateway can forward messages to the Telegram integration on UBOS, which then pushes the payload to the appropriate agent.

When combined with the OpenAI ChatGPT integration, the gateway can act as a thin proxy that adds company‑specific context before hitting OpenAI’s API, reducing token usage and latency.

Shared Memory Model

OpenClaw’s memory model is a versioned key‑value store built on Chroma DB integration. Each agent reads a snapshot of the current state and writes a new version atomically, ensuring consistency without locking.

Key features:

• Time‑travel queries – agents can retrieve historical states for audit trails.
• Vector‑based similarity search – ideal for semantic retrieval of embeddings.
• TTL (time‑to‑live) policies – automatically purge stale data.

The memory model also supports cross‑agent communication. For example, a sentiment analysis agent can write its score, and a downstream response generation agent can read that score to adjust tone.

Agent Layer – Plug‑and‑Play AI Modules

Agents are isolated micro‑services written in Rust, Python, or JavaScript. They expose a simple process(event, state) → new_state contract. UBOS provides a marketplace of ready‑made agents, such as:

• AI SEO Analyzer – scans website content and returns optimization suggestions.
• AI Article Copywriter – generates long‑form drafts from bullet points.
• AI Chatbot template – a fully‑featured conversational bot with context handling.
• ElevenLabs AI voice integration – adds natural‑sounding speech synthesis.

For enterprises that need custom logic, developers can upload a Docker image to the UBOS portfolio examples page, where it becomes instantly discoverable by other tenants.

AI marketing agents are a special class that combine data enrichment, copy generation, and campaign orchestration. Learn more about them in the AI marketing agents section.

Integrations – Extending OpenClaw with Third‑Party Services

OpenClaw’s design encourages “plug‑and‑play” integrations. Below are the most popular ones, each available as a one‑click install from the UBOS marketplace:

• ChatGPT and Telegram integration – enables bidirectional chat between users on Telegram and a ChatGPT‑powered agent.
• ElevenLabs AI voice integration – adds high‑fidelity TTS to any response.
• Chroma DB integration – provides vector search for semantic memory.
• OpenAI ChatGPT integration – direct access to GPT‑4/3.5 with custom system prompts.

These integrations are orchestrated through the Workflow automation studio, where you can drag a “Telegram → ChatGPT” block, set triggers, and publish the workflow in seconds.

Step‑by‑Step Setup Flow for OpenClaw on UBOS

1. Create a UBOS account

Visit the About UBOS page, click “Sign Up”, and verify your email.

2. Choose a hosting plan

Navigate to UBOS pricing plans. For production workloads, the “Enterprise” tier provides dedicated CPU, SSD storage, and SLA‑backed uptime.

3. Deploy OpenClaw via the marketplace

In the UBOS templates for quick start, search for “OpenClaw”. Click “Deploy”, select your region, and confirm.

4. Configure the gateway

Open the Web app editor on UBOS, add a new “Gateway” component, set JWT secret, and enable WebSocket support.

5. Attach agents

From the UBOS partner program page, browse the agent marketplace. Drag “AI SEO Analyzer” and “AI Article Copywriter” onto the canvas, connect them to the memory store, and save.

6. Enable integrations

Add the “Telegram integration on UBOS” block, paste your bot token, and link it to the “ChatGPT and Telegram integration”. Test the flow by sending a message to your Telegram bot.

7. Monitor and scale

Use the built‑in UBOS portfolio examples dashboard to view latency, error rates, and memory usage. Scale the gateway or agents with a single click.

8. Go live

Once testing is complete, switch the DNS entry to the UBOS‑provided endpoint and enable HTTPS. Your OpenClaw instance is now production‑ready.

UBOS vs. DIY Hosting: The Clear Advantage

Traditional DIY deployments require you to manage Docker, Kubernetes, SSL certificates, and scaling policies manually. UBOS abstracts all of these complexities:

• One‑click deployment of OpenClaw and all its agents.
• Automatic TLS via Let’s Encrypt, no manual cert handling.
• Built‑in monitoring with alerts and auto‑scaling rules.
• Marketplace of vetted agents that are security‑scanned and versioned.
• Enterprise support through the UBOS partner program, including SLA guarantees.

For startups, the UBOS for startups bundle includes free credits for the first three months, making it risk‑free to experiment with OpenClaw. SMBs benefit from the UBOS solutions for SMBs, which bundle compliance tools and multi‑tenant isolation.

Real‑World Use Cases Powered by OpenClaw

Customer Support Automation

A SaaS company integrated the Customer Support with ChatGPT API agent, connected it to the Telegram gateway, and reduced ticket response time by 62 %.

Content Generation at Scale

A digital marketing agency used the AI Article Copywriter together with the AI SEO Analyzer to produce 500 SEO‑optimized blog posts per month, cutting writer costs by 40 %.

Multilingual Voice Assistants

By combining the Multi-language AI Translator with the ElevenLabs AI voice integration, a travel startup launched a 24/7 voice guide that speaks 12 languages with near‑human intonation.

FAQ

Is OpenClaw open source?

The core runtime is released under the Apache 2.0 license. UBOS provides commercial support, hosted services, and a curated marketplace.

Can I run OpenClaw on-premises?

Yes. UBOS offers an on‑prem installer that mirrors the cloud experience, including auto‑updates and local monitoring.

How does OpenClaw handle data privacy?

All data stays within your tenant’s isolated memory store. No logs are sent to third‑party services unless you explicitly add an integration.

What languages are supported for agents?

Agents can be written in Rust, Python, Node.js, or any language that can expose a HTTP/gRPC endpoint.

Conclusion

OpenClaw’s modular architecture, robust gateway, versioned memory model, and thriving agent marketplace make it the go‑to framework for AI‑driven automation. Coupled with UBOS’s one‑click deployment, built‑in security, and enterprise‑grade support, you can launch production‑ready AI services in hours—not weeks.
