Privacy
Good privacy posture for most teams, especially when self-hosted or carefully configured.
Most usage data runs through a managed vendor environment, so privacy control is limited.
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.
monday Agent Factory pros
- 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
monday Agent Factory cons
- Closed-source offering, so portability and vendor transparency are limited.
- Privacy controls are limited compared to self-hosted alternatives.
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.
