LettaBot vs. OpenFang
LettaBot
OpenFang
A multi-channel personal AI assistant with unified persistent memory across Telegram, Slack, Discord, WhatsApp, and Signal, built on the Letta platform. Now officially deprecated and archived in favor of Letta Code's Channels and Remote Environments.
A Rust-built 'Agent Operating System' shipping as a single ~32MB binary with autonomous scheduled agents ('Hands') instead of chat-driven prompts. Ambitious and heavily tested, but pre-1.0 with breaking changes and a release cadence that appears to have stalled since May 2026.
Verdict
OpenFang has the stronger current case.
Useful guidance with a reasonable evidence base behind it. AI decision layer last reviewed Oct 5, 2026. AI decision layer last reviewed Oct 5, 2026.
Choose LettaBot if
- you specifically need existing deployments that still work and need short-term continuity
- you specifically need developers studying a hackable multi-channel agent reference implementation
Neither if
Nothing in the current evidence rules both of them out.
Choose OpenFang if
- you want to keep more of the workflow local or optional-cloud
- you want lower day-two risk and fewer hardening surprises
- privacy defaults and containment matter more than raw flexibility
