Breaking Free from the Cloud: Self-Hosted AI Agent Architecture

Most AI agents today run on rented cloud infrastructure with no control over costs, uptime, or vendor decisions. Self-hosting on microcontrollers like the ESP32 flips this model—giving you ownership of your entire stack, from hardware to logic layers. While setup requires more work upfront, it eliminates vendor lock-in and enables true physical agency where agents can interact with the real world through actuators and sensors.
