Letta pros
- Open source with transparent code and flexible deployment options.
- Strong privacy story for users who care where data runs.
- Good memory and persistence support for ongoing conversations or tasks.
Majordomo pros
- Strong privacy story for users who care where data runs.
- Can handle meaningful autonomous work instead of acting only as a reactive chatbot.
Letta cons
- Lower autonomy — designed more as a platform than an out-of-box assistant
- Setup requires understanding memory architecture concepts
- Python-only — no native TypeScript/JavaScript implementation
Majordomo cons
- Closed-source offering, so portability and vendor transparency are limited.
- Security posture is weak for high-trust or regulated workflows.
- Channel coverage is narrow, so distribution options are constrained.
Letta gotchas
- You should expect ongoing hosting, uptime, and secret-management work if you deploy it for real users.
- Recurring subscription or model spend can matter more than the headline feature list.
Majordomo gotchas
- This is an add-on, not a full standalone assistant, so you will usually pair it with another agent.
