The free, open-source AI assistant formerly known as Clawdbot has officially rebranded to Moltbot in January 2026. The change was widely anticipated: the tool had grown in popularity on platforms like X (Twitter), where early adopters, AI power users, and internet personalities praised it. Many users rely on Claude, Anthropic's family of large-language models, to power the assistant—and the name "Clawdbot" (with mascot "Clawd") was close enough to "Claude" to attract trademark attention.
Creator Peter Steinberger confirmed the rebrand in a post on X and in a new "lore" post on GitHub. He described receiving a "polite" request from Anthropic to change the name for trademark reasons. Rather than fight it, the project embraced the change with a theme that fits the existing mascot: a space lobster.
What Is Moltbot (Formerly Clawdbot)?
Moltbot is a free, open-source AI assistant that lets users interact with AI models through a friendly interface. A significant portion of its user base runs it with Claude models from Anthropic, which offer strong reasoning and instruction-following. The project gained traction for being accessible, community-driven, and not locked behind a single vendor.
From Clawd to Molty: The Mascot Rebrand
The original mascot was a "space lobster" named Clawd, living in "Clawdbot." Lobsters are known for their claws—hence the pun with "Claude." After Anthropic's request, the character was reimagined around another lobster trait: molting. In January 2026, the lobster "molted," shedding its old shell and emerging as Molty in Moltbot. The official lore states: "New shell, same lobster soul."
Turbulence Along the Way
Before the rebrand, the project faced other challenges. Steinberger noted on X that the Clawdbot GitHub repository was briefly taken over by crypto scammers, highlighting the attention—and risk—that comes with a viral open-source project. The incident was resolved, but it underscored the need for clear branding and ownership.
Where to Find Moltbot Now
The GitHub repository has been updated to reflect the new name, and the former clawd.bot website is being replaced by molt.bot. Functionality remains the same; only the name and branding have changed. Users who relied on Clawdbot can continue using the tool as Moltbot without losing features or access.
Why Trademark Matters for Open-Source AI
The Clawdbot-to-Moltbot story is a reminder that open-source projects using third-party AI APIs still operate in a landscape shaped by trademark and branding. Names that sound or look like established products (such as Claude) can lead to legal or procedural requests from rightsholders. Choosing distinct names and mascots helps projects stay clear of such issues while keeping community identity intact.
