Chrys Bader has created ClawCharts to track the popularity and growth of OpenClaw and its growing number of competitors.
I have an unused Raspberry Pi 4 4GB that I’ve been meaning to test one of these Claw-like personal agents on (locked down to prevent the security nightmare scenarios we’ve seen play out since OpenClaw took off).
OpenClaw is a bit of a resource hog (which is why so many people are running out to buy Mac Minis), so I’ve been looking at the list of lightweight competitors. There is no obvious reason to prefer one over the other, so I’ll probably go with the fast-growing ZeroClaw.
ZeroClaw offers OAuth connectors for OpenAI and Anthropic subscription plans, but presently neither company is clear on whether this usage is permissible or not. Anthropic recently blew up the OpenClaw community by updating their docs to specifically ban using OAuth outside of Claude Code. An Anthropic employee partially walked this back on Twitter, but there is still no clear statement whether this use case is permitted. Regarding the use of OAuth from OpenAI for OpenClaw (specifically, GPT Codex), Peter Steinberger, creator of OpenClaw, stated on Twitter: “that already works, OAI publicly said that”. No one can seem to find this public statement, but it’s worth noting that Steinberger himself is now an OpenAI employee. So, will you get banned for using your ChatGPT Plus/Pro or Claude Pro/Max subscriptions with OpenClaw? Nobody knows.
I’ll probably go with the OpenRouter API instead for now.
Update (2025-02-27): Google also confirms on Twitter that Antigravity logins are not meant to be used with third party tools.
