The New Wave of Agents (which I call Generation IV agents) is sweeping across organizations everywhere. This article provides a basic perspective for those who want to get started.
In November 2025, Peter Steinberger published a prototype on GitHub called OpenClaw. Within just 84 days, the project attracted 200,000 stars, becoming the fastest-growing software project in GitHub history.
I. INTRODUCING SIX KEY PLAYERS
Right now, the whole world is talking about OpenClaw and its variations as the next generation of agents.
This article summarizes six major variants, aiming to give readers the essential information needed to decide which one to use.
1. NanoClaw – Minimalist Container Isolation System
Codebase: Only about 500 lines of TypeScript.
Design philosophy:
Minimal source code, maximum isolation. NanoClaw demonstrates that fully functional AI agents can be built with extremely small codebases.
The real innovation lies in its security model - assigning each WhatsApp group its own isolated Linux container, creating true OS-level boundaries rather than relying on application-level permission checks.
Technology stack
- TypeScript
- WhatsApp (Baileys)
- Claude Agent SDK
- SQLite
- Docker / Apple Container
Best suited for
- People who want to clearly understand what intelligent agents can do
- Those especially concerned about security and isolation
- Developers who want to inspect the entire agent stack at once
2. Nanobot – A Powerful MCP Research Tool
Codebase: Around 4,000 lines of Python, about 99% smaller than OpenClaw.
Design philosophy:
Ultra-lightweight, MCP-first architecture, research-ready.
The core design question is:
“What is the minimum amount of code required to build a fully functional, multi-platform AI agent?”
Nanobot adopts an MCP-first architecture, where:
- The agent acts as a simple orchestrator
- Core capabilities are implemented via external MCP tool servers
Technology stack
- Python
- Supports 12+ platforms
- Supports 12+ LLM providers
- MCP tool servers
Performance
- ~100MB RAM usage
- Startup time: 0.8 seconds
Best suited for
- Developers wanting to deeply understand agent architecture
- Researchers needing clean and customizable codebases
- Users who want cross-platform messaging without OpenClaw’s complexity
3. OpenClaw – The Full-Scale Giant
Codebase
- 400,000+ lines of TypeScript
- 200,000+ GitHub stars
- 5,700+ skills
Design philosophy:
Fully featured, ready to deploy immediately after installation.
OpenClaw is the pioneering project that sparked the entire “Claw ecosystem.”
It uses a three-layer hub-and-spoke architecture:
-
Gateway – acts as the central nervous system
-
Channel adapters – connect to messaging platforms
-
Agents – execute real-time AI loops
Technology stack
- TypeScript
- 11+ messaging platforms
- Multi-model search and hybrid vector search
- Claude / GPT / DeepSeek
Performance
- Startup time: ~6 seconds
- Memory usage: ~1.5GB
Cost and risks
Extremely complex - can take weeks or months to fully understand.
Andrej Karpathy described it as:
“a 400,000-line monster.”
Security concerns include:
- Data leakage incidents
- Remote Code Execution (RCE) vulnerabilities
- Supply-chain poisoning risks
Best suited for
- Teams wanting the most complete AI assistant platform available
- Those who value a large skills ecosystem and community support
4. IronClaw – The Rust Security Fortress
Codebase: Completely rewritten in Rust with five security layers.
Design philosophy
Security first.
Multi-layer defense.
Zero trust.
IronClaw was built by security researchers who reviewed the agent ecosystem and decided to “build it properly.”
It directly addresses Karpathy’s security concerns.
Five-layer security architecture
-
Network Layer
- TLS 1.3 encryption
- SSRF protection
- Rate limiting
-
Request Filtering Layer
- Endpoint allowlists
- Prompt injection detection
- Content sanitization
-
Credential Management Layer
- AES-256-GCM encryption
- Credential injection
- Sandbox environments with no direct access
-
Execution Sandbox Layer
- Dual sandbox: WASM + Docker
-
Audit Layer
- Full activity logging
- Anomaly detection
Technology stack
- Rust
- PostgreSQL + pgvector
- Hybrid search algorithm (RRF)
Performance
- Binary size: 3.4MB
- Startup time: <10ms
- Memory usage: ~7.8MB
Best suited for
- Security-first organizations
- Teams deploying production-grade systems
5. PicoClaw – Edge Computing Agent
Codebase: 95% of the code written by AI agents.
Design philosophy
Run anywhere.
On any device.
At near-zero cost.
PicoClaw asks a bold question:
“What if your AI agent could run on $10 hardware?”
Technical highlights
- Operates with <10MB memory
- Startup under 1 second on a 0.6GHz CPU
- Supports RISC-V, ARM, and x86 architectures
It can run on:
- LicheeRV-Nano
- Raspberry Pi
- old smartphones
- cloud servers
Personality system
Agent behavior is defined using seven Markdown files
- identity.md
- personality.md
- knowledge.md
- rules.md
- skills.md
- plans.md
- self.md
Development model
- AI bootstrapping
- agent-driven architecture transformation
- code optimization
- human feedback
- roadmap adjustment
Best suited for
- Edge computing and IoT deployments
- Resource-constrained environments
- Experimenting with AI agents on unusual hardware
6. ZeroClaw – Vendor-Independent Universal Agent
Codebase: 13 core components, all replaceable.
Design philosophy
Feature-oriented architecture.
Vendor independence.
The key idea:
“What if you could replace any component without changing the code?”
Core components include
- Provider – abstract LLM provider
- Channel – standardized messaging platform
- Long-term memory – abstract storage system
- Tools – plugin execution framework
Long-term memory system
Uses hybrid vector + keyword search in SQLite.
- Embeddings stored as BLOBs with cosine similarity
- FTS5 virtual table with BM25 scoring
- Configurable weighted merging
Everything runs locally in a single file, with no external vector database required.
Performance
- Binary size: 3.4MB
- Startup time: <10ms
- Runtime memory: <5MB
Best suited for
- Teams with diverse infrastructure needs
- Developers wanting easy switching between LLM providers
- Production deployments needing operational flexibility
- Those who want to avoid vendor lock-in
