Claude Cowork vs Claude API vs OpenClaw — Which to Choose?

The Core Distinction

Choose Claude Cowork If…

• Your team is non-technical and can't or won't set up software on a server
• You need shared workspaces where team members collaborate around Claude-generated documents
• You need zero ops overhead — Anthropic handles uptime, updates, and security
• Your use case fits the product: content creation, document editing, team Q&A, brainstorming, light data analysis
• You're in a regulated industry and need SOC 2 compliance on Business tier, or data residency on Enterprise
• You want official integrations (Google Drive, GitHub, Slack, Jira) without building them

Choose the Claude API If…

• You're building a product — something your customers or users interact with directly
• You need programmatic control — call Claude from your code, integrate it into your pipeline, process thousands of documents automatically
• Your usage is high-volume — the API's per-token pricing is significantly cheaper than Cowork at scale
• You need to control exactly what the model sees and does — system prompt, conversation history, tool definitions, output parsing
• You have a developer who can build and maintain the integration

The Claude API is documented at docs.anthropic.com. It's a standard REST API with official SDKs in Python, TypeScript, and more.

Choose OpenClaw + Claude If…

• You want model flexibility — start with Claude, try Gemini, switch to local Ollama, come back to Claude — without changing your agent setup
• You want your agent on messaging apps — WhatsApp, Telegram, Discord, iMessage. Cowork is web-only.
• You want the data on your own server — your conversations stay on your machine; only the model inference call reaches Anthropic
• You want the 53-skill ecosystem — weather, GitHub, email, notes, system monitoring, and more
• You want to automate personal workflows — morning brief, email triage, recurring tasks — that don't fit a team document editor
• You need the cost of Cowork to go down — OpenClaw + Claude API is typically 50–70% cheaper than Cowork Business for equivalent usage once you account for per-token API pricing

Hybrid: Cowork + OpenClaw Together

Many teams use Cowork and OpenClaw simultaneously for different purposes — they don't conflict:

Migrating from Cowork to OpenClaw

If you've been using Cowork and want to move to self-hosted, the main things to migrate are:

1. Export artifacts before they expire

# In Cowork:
Project Settings → Export → Download all artifacts as ZIP
# Or export individually: Artifact → ⋮ → Export As → Markdown

2. Convert your system prompts to SOUL.md

Your Cowork project system prompts become OpenClaw workspace files. The format is similar — paste your system prompt into ~/.openclaw/workspace/SOUL.md and adjust the section headings to match the SOUL.md template.

3. Move knowledge documents to MEMORY.md or the workspace

Cowork knowledge documents become either:

• MEMORY.md facts — for short, factual items (product name, team glossary, key decisions)
• Workspace files — for longer documents, save them to ~/.openclaw/workspace/ and reference them in AGENTS.md so your agent reads them at session start

4. Replace integrations with skills

# Cowork GitHub → OpenClaw
openclaw skill install github
ironclaw allowlist add github --network "api.github.com:443"

# Cowork Google Drive → no direct equivalent skill yet
# Use the filesystem skill + manual sync, or the Google Drive MCP server in Hermes

# Cowork Slack → OpenClaw
openclaw skill install slack   # if available; or use Slack's webhook API directly

5. Set up a channel

OpenClaw doesn't have a web UI like Cowork. Pick a channel that works for your team — Telegram is the easiest, Discord works well for teams already there. See the Telegram Setup guide for the full walkthrough.

Migrating from Claude API to Cowork

Moving in the other direction — from a custom Claude API integration to Cowork — is less common but happens when:

• The team that built the API integration left and no one can maintain it
• The use case turned out to be collaborative rather than automated
• The business needs SOC 2 compliance that Cowork's Business tier provides

Cowork doesn't offer an API-import path. Rebuild the system prompts in Cowork's Project Instructions, convert any knowledge documents to file uploads, and rebuild any automated workflows as manual Cowork workflows with system prompt templates. Conversations and history from your API integration cannot be imported.
