Feature by feature
Based on each project's documentation and publicly reproducible benchmarks.
| Feature | OpenClaw | ZeroClaw |
|---|---|---|
| Language / runtime | TypeScript — requires Node.js (~390MB overhead) | Rust — single static binary, no runtime dependencies |
| RAM usage (idle) | 800MB – 1.5GB | < 5MB |
| Startup time (0.8GHz core) | 8 – 15 seconds | < 10 milliseconds |
| Binary size | ~28MB + Node.js runtime | ~8.8MB — no external runtime |
| Runs on $10 hardware | ||
| GitHub stars | 370k+ | 30.4k |
| Community skill ecosystem | 700+ community skills on ClawHub | Growing — smaller library |
| Channel support | Telegram, Slack, Discord, WhatsApp, email & more | 30+ channels — WhatsApp, Telegram, Slack, Discord, Signal, iMessage, Matrix, IRC & more |
| Scheduled tasks (cron) | Native cron system | Native cron system |
| Persistent memory | Database-backed (frequent community complaints about forgetting) | SQLite + vector search — hybrid full-text & semantic recall |
| Security defaults | Not secure by default — manual hardening required | Secure by default — DM pairing, command allowlists, sandboxing, 129+ security tests |
| Hardware peripheral support | ESP32, STM32, Arduino, Raspberry Pi GPIO | |
| Migrate from OpenClaw | N/A | `zeroclaw migrate openclaw` — imports memory, config & workspace |

Going with OpenClaw? KiloClaw handles the hosting so you don't have to.
Try KiloClaw FreeHonest assessment
Neither is strictly better. They make different trade-offs for different use cases.
370k+ GitHub stars — the largest community
More contributors, more skills, more answered questions. If you hit a problem, someone has already solved it.
700+ community skills on ClawHub
Email, search, Notion, GitHub, Jira, and hundreds more — ready to install with one command.
More accessible for non-developers
OpenClaw has a polished web UI and better onboarding materials. ZeroClaw assumes comfort with a terminal and TOML config.
Broader hosting ecosystem
KiloClaw, and a dozen other managed hosts, are purpose-built for OpenClaw. ZeroClaw managed hosting options are limited.
Needs a real server — $10 hardware won't run it
OpenClaw requires 800MB–1.5GB RAM. Running five agents means committing 5GB+ of memory.
Slow cold starts — 8–15 seconds
Node.js startup is expensive. On low-cost VPS plans this adds up across agent restarts.
Updates frequently break configs
With 82+ releases, the r/openclaw community consistently reports update-induced regressions. Not secure by default — hardening is manual.
<5MB RAM — runs on hardware OpenClaw can't
Raspberry Pi, ESP32, $10 VPS — ZeroClaw runs comfortably where OpenClaw would crash or crawl.
Starts in <10ms
Cold start is near-instant. Restarts after updates or crashes are imperceptible.
Secure by default
DM pairing, strict sandboxing (Landlock on Linux, Bubblewrap), command allowlists, 129+ security tests in CI. You opt in to trust rather than opting out.
30+ channels including Signal, iMessage, Matrix, IRC
ZeroClaw reaches channels OpenClaw doesn't ship natively — useful for privacy-sensitive or enterprise deployments.
Smaller skill ecosystem
700+ OpenClaw skills on ClawHub vs a growing ZeroClaw library. If you need a specific integration today, OpenClaw is more likely to have it.
Steeper setup curve for non-developers
TOML config, Rust build toolchain for source installs, no GUI walkthrough. ZeroClaw assumes CLI comfort.
Fewer managed hosting options
KiloClaw and the broader OpenClaw hosting ecosystem are built for OpenClaw. ZeroClaw self-hosting is well-documented, but managed options are limited.

Explore use casesManaged OpenClaw hosting
KiloClaw is managed OpenClaw hosting. Same open-source agent, same skills, same integrations — without the Docker setup, the breaking updates, or the security hardening.
No SSH. No Docker. No YAML. Pick your model, connect your chat platform, and your OpenClaw instance is running.
Route through Kilo Gateway — free, balanced, or frontier models. You pay provider rates, nothing extra.
Your agent doesn't die at 3 AM. VM isolation, auto-restart, health monitoring. Built on infrastructure serving 3M+ Kilo Code users.
Simple pricing

AI inference billed separately via Kilo Gateway. 500+ models, zero markup.
Yes — ZeroClaw ships a `zeroclaw migrate openclaw` command that imports your memory, workspace files, and config from `~/.openclaw/`. Config is converted from JSON to TOML automatically. Run it with `--dry-run` first to preview what will change.
Not directly — ZeroClaw has its own skills/plugin system built around Rust traits. OpenClaw skills are written in the context of the TypeScript/Node.js runtime. However, ZeroClaw supports 70+ built-in tools (shell, file I/O, browser, git, MCP, Jira, Notion, Google Workspace) and a growing community skill library.
ZeroClaw actually supports more channels than OpenClaw — 30+ including Signal, iMessage, Matrix, IRC, Bluesky, Nostr, MQTT, WeChat Work, and more. Both support the main ones: WhatsApp, Telegram, Slack, Discord, and email.
KiloClaw is purpose-built for OpenClaw — the same open-source project, with 370k+ GitHub stars, the largest community, and the most mature skill ecosystem. ZeroClaw is a genuinely impressive project but it's younger, has a smaller skill library, and has limited managed hosting options. KiloClaw is the answer to "I chose OpenClaw and don't want to manage the infrastructure."
ZeroClaw's lean runtime makes self-hosting easier than OpenClaw — a single static binary, no Node.js, runs on a $10 VPS. The ZeroClaw docs cover setup thoroughly. If you want managed OpenClaw hosting instead, KiloClaw has you covered at $9/mo.
KiloClaw deploys your OpenClaw instance in under 5 minutes. 500+ models via Kilo Gateway, infrastructure that doesn't break at 3 AM.
