OpenCrabs: AI Agent Platform Open Source yang Lo Self-Host Sendiri (Review Jujur 2026)

Description and use

OpenCrabs is a self‑hosted AI agent platform written in Rust that runs on a 1 GB VPS. It offers full data ownership, zero telemetry, and easy migration via rsync. Ideal for Indonesian businesses needing local data control and cost‑effective automation.

Problem

Many AI agent platforms are cloud‑only, forcing users to store conversation data on third‑party servers, pay subscription fees, and risk service outages if the provider shuts down.

Outcome

OpenCrabs enables local, cost‑effective AI agent automation with full data ownership, zero telemetry, and easy migration, making it suitable for Indonesian businesses that need control over data and infrastructure.

Workflow

• Install OpenCrabs via Homebrew or download the binary from GitHub releases
• Run the binary and use the built‑in CLI to configure channels (Telegram, WhatsApp, Discord, Slack, Trello) and tools
• Add custom shell commands as tools via tools.toml for hot reload
• Set up multi‑agent communication using the A2A JSON‑RPC gateway on port 18790
• Schedule periodic tasks with cron/heartbeat
• Use local STT/TTS and browser automation via CDP
• Backup the data folder with rsync and migrate to a new VPS by copying the folder and restarting the binary
