eidan vs Claude in Slack
A hosted Claude teammate inside Slack vs. a self-hosted agent host you own — and eidan runs Claude models too.
This one's a friendly comparison — eidan happily runs Claude models too. The difference isn't the model, it's the architecture: Anthropic's Claude teammate is a hosted assistant inside Slack; eidan is a self-hosted agent host you own.
Claude in Slack is frictionless and team-native, with memory and data held on Anthropic's and Slack's servers. eidan keeps the agent, the memory, and the data on your own infrastructure — and lets you point it at Claude (or any model) on your own keys.
