How to Migrate from CrewAI to OpenClaw

CrewAI and OpenClaw solve the same problem, multi-agent coordination, but they start from opposite ends. CrewAI is a Python framework where you define agents, tasks, and crews in code. OpenClaw is a local-first gateway where you define agents in Markdown and connect them to messaging channels without writing code.

The core difference: CrewAI treats agent creation as a programming problem, while OpenClaw treats it as a configuration problem.

Here is how the major concepts map across:

CrewAI Agent (role, goal, backstory) maps to OpenClaw SOUL.md (Identity, Personality, Rules sections). Where CrewAI uses Python class attributes, OpenClaw uses Markdown headings in a file that loads at the start of every session.

CrewAI Task (description, expected output, assigned agent) maps to OpenClaw subagent delegation. Instead of defining tasks as objects in a list, you describe work in natural language and spawn subagents to handle it.

CrewAI Crew (collection of agents with a process type) maps to OpenClaw's gateway with AGENTS.md. The gateway orchestrates sessions, while AGENTS.md defines routing rules and security policies.

CrewAI Tools (Python functions or LangChain integrations) map to OpenClaw Skills (installable packages from ClawHub). Skills give agents capabilities like file management, web search, or API access.

CrewAI Memory (optional, enabled per crew) maps to OpenClaw's file-based memory system. OpenClaw agents write to MEMORY.md for long-term facts, daily notes for session context, and can use backends like SQLite, LanceDB, or Honcho for semantic search.

This is not a one-to-one swap. Some patterns translate cleanly, others require rethinking how you structure work. The sections below walk through each layer.

Start with your CrewAI agent definitions. Each agent has a role, goal, and backstory. In OpenClaw, these become sections in a SOUL.md file stored in your agent's local workspace directory.

A CrewAI agent defined as:

researcher = Agent(
    role="Market Researcher",
    goal="Find accurate market data for quarterly reports",
    backstory="Senior analyst with 10 years in fintech research",
    tools=[search_tool, scrape_tool],
    allow_delegation=True
)

In OpenClaw, this becomes a Markdown-based agent definition file. The role, goal, and backstory translate into structured sections that describe identity, personality, and behavioral rules. Tools become skills installed from the ClawHub registry rather than Python imports.

Tasks become subagent delegations. CrewAI tasks are objects with descriptions, expected outputs, and agent assignments. OpenClaw handles this through its subagent system: the parent agent describes a piece of work, a subagent picks it up in an isolated session, completes it, and delivers results back. The key difference is that you describe tasks in natural language rather than defining them as Python objects.

Crews become the gateway. A CrewAI crew wraps agents and tasks with a process type (sequential or hierarchical). OpenClaw's gateway handles orchestration at the platform level. Sequential workflows run subagents one after another, passing results forward. Hierarchical workflows use nested delegation, where a coordinating agent manages worker subagents underneath it.

For sequential CrewAI processes, the OpenClaw equivalent spawns subagents in order and feeds each result into the next task's context. For hierarchical processes, where a manager delegates to workers, OpenClaw supports nested subagent trees with configurable depth limits. The coordinating agent delegates to workers, collects their results, and synthesizes everything before reporting back.

Give Your OpenClaw Agents a Shared Workspace

Fastio gives OpenClaw agents generous storage with file locking, Intelligence Mode for automatic RAG, and ownership transfer for human handoff. No credit card, no trial expiration.

Once you understand the concept mapping, here is the practical migration path.

Step 1: Set up the gateway. Run the OpenClaw onboarding command to install the gateway as a user service, then start it in verbose mode for initial debugging. This is your new control plane, replacing CrewAI's Python runtime.

Step 2: Convert agent definitions. For each CrewAI agent, create a SOUL.md that captures its identity and behavioral rules. AGENTS.md handles the operational layer, defining routing, security policies, and scope boundaries. TOOLS.md lists which skills each agent can access.

Step 3: Replace Python tools with ClawHub skills. Browse the ClawHub registry for equivalents to your CrewAI tools. Skills install into ~/.openclaw/workspace/skills/ and extend agent capabilities without custom code. If you have complex Python tools with database queries or ML inference, these may not have direct skill equivalents. The CrewClaw comparison guide suggests a hybrid approach for this case: keep CrewAI for agents that need heavy Python tooling while moving communication-heavy agents to OpenClaw.

Step 4: Configure subagent delegation. Set concurrency and depth limits in your gateway config. The defaults allow 5 children per agent and 8 concurrent subagents globally. Adjust based on your workload. For most CrewAI crew migrations, maxSpawnDepth: 1 handles flat task lists and maxSpawnDepth: 2 handles hierarchical crews.

Step 5: Wire up messaging channels. One of OpenClaw's biggest advantages over CrewAI is built-in channel support. Connect Telegram, Slack, Discord, WhatsApp, Signal, or any of the 20+ supported platforms directly through the gateway. CrewAI requires custom integration code for every channel.

Step 6: Migrate memory. CrewAI's optional memory system persists context across tasks within a crew run. OpenClaw's memory is more granular. MEMORY.md stores durable facts that load every session. Daily note files (memory/YYYY-MM-DD.md) capture running context. For semantic search across memory, configure an embedding provider (OpenAI, Gemini, Voyage, or Mistral) and choose a backend. The built-in SQLite backend works immediately. LanceDB, QMD, and Honcho offer different tradeoffs for cross-session awareness and local-first operation.

OpenClaw also has a memory flush mechanism that runs before conversation compaction, prompting agents to save important context so nothing gets lost during long sessions. CrewAI does not have an equivalent.

CrewAI agents typically read and write files locally, which works fine for a single machine but breaks down when agents need to share work, survive restarts, or hand off results to humans.

OpenClaw agents face the same challenge. The local workspace directory is single-machine by default. For production multi-agent setups, you need a shared storage layer that all agents can access reliably.

Local disk works for prototyping. You can point agents at a shared directory or mount a network volume. But you lose versioning, access control, and any way to hand files to a non-technical stakeholder.

Cloud storage like S3 or Google Cloud Storage handles durability and sharing, but you need to build the access layer yourself. There is no built-in search, no file locking for concurrent agents, and no way for a client to browse results without custom tooling.

Fastio fills this gap as a workspace layer purpose-built for agent teams. Your OpenClaw agents get shared workspaces with file locking for concurrent access, Intelligence Mode for automatic RAG indexing, and branded shares for delivering results to humans. The MCP server exposes these capabilities through 19 consolidated tools that any agent can call.

The Business Trial gives you 50GB of storage, included credits, and 5 workspaces with no credit card required. That is enough to run a migrated CrewAI pipeline without spending anything on infrastructure. Sign up at fast.io/storage-for-agents.

For teams migrating production CrewAI workflows, the ownership transfer feature is worth noting. An agent can build an entire workspace, populate it with results, and then transfer the organization to a human stakeholder. The agent keeps admin access for ongoing updates, but the human owns the content. This pattern replaces the common CrewAI workflow of writing results to a shared drive and sending someone a link.

Migrating frameworks is a real cost. Here is an honest look at what changes.

You gain channel integrations. OpenClaw connects to Telegram, Slack, Discord, WhatsApp, Signal, and 20+ other platforms out of the box. In CrewAI, every channel is a custom build. If your agents need to interact with humans through messaging, this alone can justify the migration.

You gain persistent memory. OpenClaw's file-based memory with semantic search, daily notes, and long-term storage is more sophisticated than CrewAI's task-level memory. The dreaming system, which consolidates short-term signals into long-term memory using scoring thresholds, has no CrewAI equivalent.

You gain simpler configuration. Defining agents in Markdown instead of Python means less boilerplate and faster iteration. Non-developers can read and edit SOUL.md files, which opens agent customization to a wider team.

You lose Python ecosystem access. CrewAI agents can call any Python library directly. OpenClaw agents work through skills, which are more constrained. If your agents run pandas DataFrames, train models, or call internal Python APIs, you will need to either wrap that logic in a skill or keep those agents on CrewAI.

You lose enterprise tooling. CrewAI offers an enterprise tier with cloud deployment, monitoring dashboards, and managed infrastructure. OpenClaw is open source and local-first. You get full control, but you also own the ops work.

You lose process flexibility. CrewAI's sequential and hierarchical processes are explicit abstractions with well-documented behavior. OpenClaw's equivalent, chaining subagent spawns and using the orchestrator pattern, is more flexible but less structured. You are building the orchestration logic rather than selecting a process type.

Consider a hybrid approach. The CrewClaw project (crewclaw.com) is designed to orchestrate agents from both frameworks in the same team. Keep CrewAI for data-intensive Python agents. Move communication and coordination agents to OpenClaw. Use Fastio as the shared workspace layer between them.

Use this checklist to track your migration:

1. Inventory all CrewAI agents, noting their roles, tools, and delegation settings
2. Install OpenClaw and run the gateway locally
3. Create SOUL.md files for each agent, mapping role to Identity, goal to Personality, backstory to Rules
4. Write AGENTS.md with routing and security policies
5. Find ClawHub skill equivalents for each CrewAI tool
6. Flag any custom Python tools that need skill wrappers or hybrid treatment
7. Configure subagent depth and concurrency limits
8. Set up a memory backend and migrate any persistent context
9. Connect messaging channels
10. Set up shared storage (local, cloud, or Fastio workspace)
11. Test each agent individually before running multi-agent workflows
12. Run parallel pipelines (CrewAI and OpenClaw) during validation

Common pitfalls to watch for:

Subagent context is minimal by default. Unlike CrewAI tasks that automatically receive output from previous tasks in a sequential process, OpenClaw subagents start with a clean transcript (in isolated mode). You need to explicitly pass context in the task description, or use context: "fork" to branch the parent's transcript. Forking doubles token costs, so use it sparingly.

SOUL.md does not load for subagents. Only AGENTS.md and TOOLS.md inject into subagent sessions. If your agent's personality matters for the delegated task, include the relevant behavioral notes in the task description.

Announce delivery is best-effort. Subagent results can be lost on gateway restart. For critical pipelines, persist intermediate results to a shared workspace rather than relying solely on the announce mechanism.

Tool policies are depth-aware. Worker subagents at depth 2 cannot spawn their own children or access session management tools. Plan your agent hierarchy accordingly. The default limit of 5 children per agent and 8 concurrent subagents globally works for most migrations, but high-throughput pipelines may need tuning.
