About Cybara #
Cybara pairs a Bun-based agent runtime with a web UI, desktop and mobile apps, a CLI, and messaging-channel adapters for Telegram, Discord, Slack, WhatsApp, and 20+ more -- extended by skills, plugins, MCP (both directions), ACP, and LSP. Agents can code with checkpoint-and-rollback, drive a live embedded browser, orchestrate multi-agent runs via Mixture of Agents, and execute on-chain operations from an encrypted local wallet, all under an operator-approval policy. Bring your own model keys across 50+ providers; there is no hosted tier, telemetry, or required account. MIT-licensed, created by Carsen Klock.
Cybara is an open-source project written primarily in TypeScript, with 20 stars on GitHub. It was last updated in August 2026.
