Plakai is an automatic license-plate recognition service exposed as a SaaS API. It accepts still images, video files, RTSP streams and USB cameras, runs recognition through an ONNX/OpenCV pipeline orchestrated by FastAPI and Celery, and delivers results to tenant systems via webhooks.
It is in active alpha. The interesting engineering is in the ingestion variety - a parking barrier with a USB camera and a city stream over RTSP need very different buffering and retry behaviour, but should look identical to the API consumer.
Highlights
- Images, video, RTSP and USB camera ingestion behind one API
- ONNX/OpenCV recognition pipeline with Celery orchestration
- Multi-tenant accounts with webhook delivery
