Where they pull apart
Grok Bot
Vellum
Stands out: Vellum gives you both routes: rent a hosted assistant with its own computer, email address and subdomain, or run the same open-source assistant on your own hardware with no platform fee.
Watch out: The monthly fee mostly buys compute; the actual work is billed as credits at $1 each, so monthly cost depends on usage. Searches for Vellum also turn up its old LLM developer platform, which is a different product.
Not the right fit for
- Buyers who want a flat all-in price
- Teams that need a deep library of prebuilt connectors

Vellum
