LettaBot vs. OpenFang
LettaBot
OpenFang
A now-deprecated multi-channel AI assistant with persistent unified memory across Telegram, Slack, Discord, WhatsApp, and Signal. All active development has moved into Letta Code's Channels and Remote Environments.
OpenFang is a Rust-built Agent OS shipping as a single 32MB binary with autonomous 'Hands' that run scheduled tasks without prompting. It's pre-1.0 but battle-tested with 2,696+ passing tests and active security audits, aiming to be an autonomous agent platform rather than a chatbot.
Verdict
OpenFang has the stronger current case.
Backed by multiple direct signals plus supporting context. AI decision layer last reviewed Aug 2, 2026. AI decision layer last reviewed Aug 2, 2026.
Choose LettaBot if

- you specifically need existing lettabot users maintaining legacy deployments
- you specifically need studying the architecture of a multi-channel agent before migrating to letta code channels
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
- you depend on integrations, skills, or extension headroom
