Vellum alternative: MausBot

Vellum turned off its hosted personal assistant in November 2026. MausBot is a free, open source alternative: one team of the AI agents you already have.

Vellum was an open source personal AI assistant with long-term memory that ran on your own computer or in Vellum Cloud. Vellum turned its hosted platform off in November 2026 and says it will no longer actively maintain the code. MausBot is a free, open source Vellum alternative: one team of the AI agents you already have, on your own computer or a Cloud plan.

What Vellum is

Vellum launched Vellum Personal Assistant in 2026: one assistant with its own identity (an email address, a GitHub account and a Slack handle), eight kinds of memory with local embeddings, an hourly check of its own notes, and tools to browse, run code, send email and control a Mac. It ran on your own computer or in Vellum Cloud on plans of $30, $100 and $200 a month, on OpenAI, Anthropic, Gemini or Ollama models, and you could reach it on macOS, iOS, the web, voice, email, Telegram, Slack and Twilio. The runtime is MIT-licensed on GitHub. In its shutdown notice Vellum says competition grew fierce and it could not grow distribution enough to continue.

Launched: Earlier in 2026, per Vellum (GitHub repository created February 7, 2026); hosted platform shut down in November 2026. Sources: Vellum: Personal Assistant Platform shutdown; Vellum; Vellum: pricing; Vellum: llms.txt (product summary); vellum-ai/vellum-assistant on GitHub.

Why people look for a Vellum alternative

The hosted platform is gone: subscriptions active on November 2, 2026 were cancelled, hosted assistants were exported and turned off from November 7, and hosted data is deleted on December 13, 2026.
Vellum will no longer actively maintain the open source repository or cut regular releases; the last release is v0.12.9 of November 8, 2026. A founding engineer plans a rebranded fork called Cadet.
Restoring a hosted assistant on your own computer means adding your own model API key and reconnecting every integration, because exports leave out saved credentials.
